Definitions
- the present invention relates to a improved process for manufacturing textile products from "topped-glued" type directly from fibers and / or filaments.
- the invention also relates to a device for the implementation of the process, as well as the products obtained by said process.
- the so-called "coated-glued” products are products which are made from a textile tablecloth, and preferably from a sheet already made up of threads, or possibly from a fibrous web, which is subjected to a succession of folds in order to form folds which can be assimilated in the direction of advance from tablecloth to curls.
- This folded tablecloth is then simply attached to a support by gluing. We obtain thus a product where the threads and / or fibers do not pass through the support, unlike tufted products, which are in the form of a succession of loops crossing the support.
- the first family is the best known and understands processes using a hand-held machine which are fixed blades. A sheet of thread is pushed by these blades successively on a first folder and then on a second folder which is parallel to the first in order to form by folding a succession of loops. Then, these loops are secured to a support, which is preferably previously coated with a glue such as polyvinyl chloride plastisol, on which loops will be dropped, the whole as well constituted by the support and the integral loops being then subjected to a heat treatment, for example a passage through an infrared oven.
- a glue such as polyvinyl chloride plastisol
- the loops can be held between two front supports that a hot melt adhesive does not pass through said supports in order to impregnate the bases of the loops.
- Another alternative is to offer the use of stretched cables to replace the blades mentioned above.
- successive folds are formed by means of a rotary system, pushing the threads and / or fibers of the sheet successively in growths present on a grooved cylinder.
- the folds are created under the action of a folding organ like a blade or a roller themselves grooved.
- a support preferably beforehand coated with glue, placed on the succession of loops obtained by folding.
- the whole support / integral loops is subjected to a treatment before they are removed from the grooved cylinder.
- the technique described consists in subjecting fibers and / or filaments "transverse looping” accompanied by a “stretching” and to obtain an accumulation of fibers and / or filaments in the form of a wavy “pseudo-thread" in which the fibers and / or filaments are parallelized.
- This step is generally called “step of (pre) looping "and should not be equated with folding.
- each fiber or filament is in principle involved in at least one loop.
- the pseudo-wire is then transported using of these transport components constituted either by the needles, either by the transfer elements, in the form transverse rows of loops, to a support to which the loops are joined.
- the first set is intended for perform a ripple step using a device constituted by the interpenetration of a first set of inverter discs with a first set of inverter fingers
- the second set is intended to achieve the classic subsequent step called the pre-closing step at using a device made up of interpenetration a second set of discs called looping discs with a second set of fingers called looping fingers, this second assembly being arranged downstream of the corrugation device relative to the direction of advance of the veil.
- the gauge of ripple device is a multiple of the gauge of the pre-loop device.
- the products offered in this document are mainly in the form of products tufted.
- the production speed which can express themselves as the product of the advance by stroke of the substrate (in mm) by the beat rate of the needles (in strokes per minute) reaches an order of magnitude of 1.5 to 4.5 m / min, which is entirely admissible to achieve tufted products but is still too weak in the case of a production comparable to a line needling, the production speed of which can reach an order of 15 m / min.
- the gauge of a so-called verticalization device may hardly be less than 1/10 inch, or 2.54 mm, unless it allows the realization of very precise and therefore relatively expensive, and which would deprive the so-called verticalization process of possibility of making inexpensive products.
- the present invention aims to provide a solution to existing limitations, and more particularly with regard to productivity, in the processes used in the technique known as verticalization as described in the documents WO91 / 00382 and WO96 / 10667.
- the present invention aims more particularly to allow the realization of products so-called "coated-glued” which may have a similar appearance of those known in the state of the art while allowing a very high productivity during the implementation process work.
- the present invention aims as complementary to allow the realization of products of type "coated-glued" fine gauge, that is to say having a gauge less than 1/10 of an inch.
- the present invention aims to allow the realization of new products that were currently impossible to achieve using the technique described as is in publications of the Applicant, and more particularly in publications WO91 / 00382 and WO96 / 10667.
- the present invention relates to a process for producing a textile product of the "topped-glued" type from fibers and / or filaments flowing in the direction of advance in the form of a veil, this process comprising at least one step called the pre-looping step in which the fibers and / or filaments undergo individually looped transversely to advance management, possibly accompanied by a transverse stretching.
- the transverse looping accompanied by stretching is carried out for each individual fiber or filament using elements rotary or looper discs spaced apart and arranged on a transverse axis with respect to the direction of advance of the veil and between which are arranged looping fingers. This allows each fiber or filament to be involved in at least one pre-loop step and allows the parallelization of these fibers and / or filaments elementary.
- the present process is characterized by that we carry out a confinement of the material under form of loops formed by fibers and / or filaments particularly well parallelized and that this confinement is produced directly on a support without there intervention of transport devices such as needles or transfer elements.
- This confinement is obtained after a first transitional stage linked to the start of a product line and during which the first loops obtained by the pre-looping step of the fibers and / or filaments individual randomly form a stop.
- the containment comes in the form of an accumulation of loops, made up of fibers and / or filaments one behind the other.
- the positioning of successive loops takes place essentially vertically using a detaching element, which guides the material to the support while holding it by tie-down.
- the support can be directly the substrate end of the product we want to make, and in fact consisting of a fiber mat, a plastic film, a PVC type backing, ....
- the material confined could be seized by an intermediate element such as a spiked mat, a brush, or a stand velcro ®, whose role is to maintain the wavy shape loops while the free end of the material is secured to a substrate.
- an intermediate element such as a spiked mat, a brush, or a stand velcro ®, whose role is to maintain the wavy shape loops while the free end of the material is secured to a substrate.
- This attachment to the substrate is done at using an adhesive whose viscosity is designed to allow a drive of fibers and / or filaments material with the substrate while performing an effective bonding.
- plastisols i.e. resins (acrylics, isocyanates, styrene-butanian, phenolic, etc.), or thermoplastics in the form of hot melt, film or powder (polyesters, polypropylene, EVA PVC, etc.), i.e. foams (PVC, acrylics, etc.), either by performing a direct adhesion by fusion of the verticalized fiber on the substrate.
- the means used to provide calories necessary for this are preferably brought by an oven infrared, a calender or a heating drum or heating blades which are in the form of flat metal parts with resistors electrical or heat transfer fluid conduits.
- the substrate feed rate can either be uniform, or be done in spurts, so that we obtain a containment of the textile material more marked on this support.
- This device essentially includes a game of discs called “looping discs” marked 11 and carried on a transverse common axis 13 driven in continuous rotation at a peripheral speed preferably equal to the speed of entry of the web 0.
- the discs looper 11 are provided on their periphery with a toothing 15 having an appropriate angle to the tangent and which allows the training of the entry veil. Between each of the discs are arranged with sulking fingers 21 the end of which is essentially so tangential to the discs.
- This device allows to carry out the so-called “pre-looping step”, which consists in subjecting the fibers and / or filaments individually a transverse looping accompanied by a stretching, in order to parallelize them correctly.
- FIG. 2a describes the step in which the veil 0 consisting of fibers and / or individual 10 filaments have just been introduced between looping discs 11 and looping fingers 21.
- the fibers and / or filaments 10 individually undergo the step of pre-loop already described and which corresponds to a loop individual transversal possibly accompanied by drawing.
- the fibers and / or filaments 10 parallelized are brought to the fingertips looper 21.
- Figure 2b shows that the fibers and / or filaments 10 which continue to be entrained by the rotating looper discs 11 are next blocked by the presence of detaching feet 31 against which they start to accumulate behind each others in order to form a stop (or "plug") 20.
- the fibers and / or filaments are strongly inclined and can even appear, at the limit, almost horizontal.
- Figure 2c shows that this stop or "plug" 20 tends to expand downward direction of a substrate 100.
- FIG. 2d shows that the "plug" 20 consisting of the accumulation of fibers and / or filaments parallelized and wavy ends up reaching such a volume that it comes into contact naturally with the substrate 100 placed just under the looping fingers 21.
- the fibers and / or filaments originating directly from the pre-loop stage condense during a step called “containment step", this time vertically, against the obstacle constituted by the "plug".
- Figure 2e shows that the "plug" 20 is driven by substrate 100, aided in this by rotation looping discs 11 and by the pressure exerted by the fibers and / or filaments 10 parallelized which continue to come from looping fingers 21.
- This phase shows that the fibers and / or filaments are then deposited regularly on the substrate 100 without there being any more of accumulation in the form of a "plug". In this case, these fibers and / or filaments are arranged so essentially vertical.
- the detaching feet 31 prefferably have a particular form to facilitate this step.
- the detaching feet are arranged so that they can be made a funnel 41 between said feet and the substrate 100 which continues to flow.
- the feet detachers 31 no longer have the function of detaching the fibers and / or filaments of the looping fingers, but rather the function of promoting the joining of said fibers and / or filaments on the substrate.
- the rounded part of detaching feet will also guide the fibers and / or filaments confined to the substrate, while its oblique part, located at a distance from the substrate slightly less than the looping height, will exert a pressure of the fibers and / or filaments parallelized so to force them to adhere to the support.
- the tension present within the fibers and / or filaments by the time they are confined to the feet detachers is less than that prevailing within the material undergoing the pre-looping step, which allows easy training of parallel fibers and / or filaments with the substrate. Indeed, if the tension undergone by fibers and / or filaments at the end of the looping fingers during the pre-loop step was less than the reaction pressure exerted by the "plug" or stop in the funnel formed by the detaching feet 31 and the substrate 100, the fibers and / or filaments 10 would start then to accumulate between the looping discs 11 and the looper fingers 21, and this until the entry of the veil. Of this fact, there would be no automatic training of the material with the substrate.
- This tension mainly depends on the orientation of the fibers and / or filaments in the veil the entrance to the verticalization device.
- the substrate 100 be previously coated with an adhesive whose viscosity has been chosen so as to allow the entrainment of fibers and / or filaments 10 with the substrate while producing a effective bonding.
- Activation devices and methods can be chosen from the devices or processes by contact, such as calenders, heating blades, etc., devices or processes working with hot air such as ovens, forced air devices, etc., or possibly the devices or processes working by irradiating, infrared energy, ....
- Figure 3 shows an embodiment preferred for the implementation of the method according to the present invention with a view to producing coated-glued products of sandwich type.
- This figure shows a disc looper 11 on which a looper finger 21 is superimposed in the extension of which is placed a detaching foot 31.
- a veil 0 of adequately oriented fibers is driven by a succession of looping discs 11.
- a plastisol deposition is carried out using a doctor blade 51 in order to secure the loops made up of fibers and / or filaments from the pre-looping stage and from the step of confinement to the substrate 100. Then, the product obtained is subjected to a heat treatment at using hot plates 54 in order to obtain a plastisol gelation. A second substrate 102 also coated with a plastisol deposited using a doctor blade 52 is then deposited on the product constituted by the first substrate 100 and the loops secured in order to create a sandwich product 60. This sandwich product 60 is again heat treated with plates heaters 56 in order to obtain the gelation of plastisol present on the second substrate 102. Finally, a blade 58 split the sandwich product 60 in two by slitting so to obtain two velvet type products 70 and 80.
- the present invention enables a series of products which it was not possible to obtain in using the methods and / or devices as described in the Applicant's previous requests.
- a first large family includes the floor, wall or automobile coverings.
- the glues used will mainly be plastisols, PVC or acrylic while the substrates can be woven, non-woven or glass mats (in the specific case of the slab).
- low-rise products but high density of flocked type velvet can be also made for gauges less than 1/16 ".
- the adhesives used are preferably thermoplastics.
- the device used for implementing the method according to the present invention does not include any sensitive organ such as needles or transfer elements which perform reciprocating movements. Therefore, we can even use coarse natural fibers.
- the second large family includes upholstery such as seat upholstery, hangings, etc.
- the gauges are particularly weak, of the order of 1/32 ", and the preferably very fine fibers used. The use of microfibers is even possible.
- the third large family relates to technical textiles which have a structure in form sandwich and which are therefore not split.
- geotextiles that can be used as a structure draining or as a structure with inclusion of powders bentonite type.
- figure 4 describes how to produce a product more precisely composite geotextile with inclusion of clay powder bentonite type.
- a device is introduced into this device veil made in the present case of fibers of a title high, for example greater than 80 dtex, possibly mixed with finer fibers, for example a title of 17 dtex which aim to facilitate the carding the veil.
- the veil 0 is entrained between the succession of discs 11 and pouting fingers 21 with a view to carry out the pre-looping and containment stages as as described in more detail in Figure 2.
- a substrate 104 is brought to the point of stain removal of fibers using a heating blade 61.
- the substrate is preferably made of fibers having a melting point higher than the melting point of the fibers present in the loops from the pre-looping steps and containment.
- This heating blade 61 allows reach a temperature that is higher than the melting temperature of the loops, which by contact adhere directly to substrate 104 in order to obtain a product 60.
- bentonite powder is deposited using conventional means 63 on the product 60 constituted by the substrate secured to the loops.
- the whole then goes on a table vibrating 65 in order to promote the migration of the powder of bentonite- within product 60 to obtain a the most homogeneous distribution possible. This is in particular possible due to high fiber content present in the loops and their resilience important, which prevents them from being crushed under the powder pressure.
- the height of the loops is also chosen according to the weight of the powder to be deposited so to get a space on the top of the product which is free of powder, so that it can be deposit with a second heating blade 67 a second substrate 105.

Abstract
Description
La présente invention est relative à un procédé perfectionné de fabrication de produits textiles de type "nappé-collé" directement à partir de fibres et/ou de filaments.The present invention relates to a improved process for manufacturing textile products from "topped-glued" type directly from fibers and / or filaments.
L'invention concerne également un dispositif pour la mise en oeuvre du procédé, ainsi que les produits obtenus par ledit procédé.The invention also relates to a device for the implementation of the process, as well as the products obtained by said process.
Les produits dits "nappés-collés" sont des produits qui sont réalisés à partir d'une nappe textile, et de préférence à partir d'une nappe déjà constituée de fils, ou éventuellement à partir d'une nappe fibreuse, qui est soumise à une succession de pliages en vue de former des plis qui pourront être assimilés dans le sens de l'avance de la nappe à des boucles. Cette nappe pliée est ensuite simplement solidarisée à un support par collage. On obtient ainsi un produit où les fils et/ou fibres ne traversent pas le support, contrairement aux produits touffetés, qui se présentent sous la forme d'une succession de boucles traversant le support.The so-called "coated-glued" products are products which are made from a textile tablecloth, and preferably from a sheet already made up of threads, or possibly from a fibrous web, which is subjected to a succession of folds in order to form folds which can be assimilated in the direction of advance from tablecloth to curls. This folded tablecloth is then simply attached to a support by gluing. We obtain thus a product where the threads and / or fibers do not pass through the support, unlike tufted products, which are in the form of a succession of loops crossing the support.
Il existe pour l'instant essentiellement deux grandes familles de procédés destinés à la réalisation de produits textiles de type "nappé-collé".There are currently essentially two major families of processes intended for carrying out "coated-glued" type textile products.
La première famille est la plus connue et comprend les procédés utilisant une machine à bras sur lesquels sont fixées des lames. Une nappe de fils est poussée par ces lames successivement sur un premier dossier, puis sur un second dossier qui est parallèle au premier afin de former par pliage une succession de boucles. Ensuite, ces boucles sont solidarisées à un support, qui est de préférence préalablement enduit d'une colle telle qu'un plastisol de chlorure de polyvynile, sur lequel les boucles seront déposées, l'ensemble ainsi constitué par le support et les boucles solidarisées étant ensuite soumis à un traitement thermique, par exemple un passage dans un four à infrarouges.The first family is the best known and understands processes using a hand-held machine which are fixed blades. A sheet of thread is pushed by these blades successively on a first folder and then on a second folder which is parallel to the first in order to form by folding a succession of loops. Then, these loops are secured to a support, which is preferably previously coated with a glue such as polyvinyl chloride plastisol, on which loops will be dropped, the whole as well constituted by the support and the integral loops being then subjected to a heat treatment, for example a passage through an infrared oven.
Selon une autre forme d'exécution, les boucles peuvent être maintenues entre deux supports avant qu'un adhésif thermofusible (hot melt) ne traverse les dits supports afin d'imprégner les bases des boucles.According to another embodiment, the loops can be held between two front supports that a hot melt adhesive does not pass through said supports in order to impregnate the bases of the loops.
On obtient dans tous les cas, que cela soit avec une solidarisation de type PVC ou de type hot melt, soit un produit d'aspect bouclé ressemblant à un produit touffeté bouclé, soit un produit de type "sandwich" constitué par des boucles emprisonnées entre deux supports que l'on peut envisager de fendre longitudinalement ensuite afin d'obtenir deux produits de type velours.In any case, we get that with a joining of PVC type or hot melt type, either a curly product looking like a product tufted curly, a product like "sandwich" constituted by loops trapped between two supports that we can consider splitting longitudinally then in order to obtain two velvet type products.
Une autre alternative consiste à proposer l'utilisation de câbles tendus pour remplacer les lames mentionnées ci-dessus.Another alternative is to offer the use of stretched cables to replace the blades mentioned above.
Selon la seconde grande famille de procédés, on effectue la formation de plis successifs grâce à un système rotatif, en poussant les fils et/ou fibres de la nappe successivement dans des excroissances présences sur un cylindre rainuré. Les plis sont créés sous l'action d'un organe plieur comme une lame ou un rouleau eux-mêmes rainurés. Ensuite, un support, de préférence préalablement enduit de colle, est disposé sur la succession des boucles obtenues par pliage. Eventuellement, l'ensemble support/boucles solidarisées est soumis à un traitement thermique avant que celles-ci ne soient retirées du cylindre rainuré.According to the second large family of processes, successive folds are formed by means of a rotary system, pushing the threads and / or fibers of the sheet successively in growths present on a grooved cylinder. The folds are created under the action of a folding organ like a blade or a roller themselves grooved. Then a support, preferably beforehand coated with glue, placed on the succession of loops obtained by folding. Eventually, the whole support / integral loops is subjected to a treatment before they are removed from the grooved cylinder.
Il convient de noter que tous ces procédés présentent les inconvénients suivants :
- leur vitesse de production reste relativement faible. A titre d'exemple, 120 coups par minute est une vitesse déjà relativement élevée pour un système à bras tel que décrit ci-dessus, dû à la complexité du mouvement produit par les organes à cames;
- la quantité d'adhésif nécessaire à solidariser les boucles au support reste importante, et de ce fait, les produits obtenus sont relativement encore trop coûteux;
- la gamme des produits de type "nappé-collé" réalisables est relativement limitée.
- their production speed remains relatively low. For example, 120 strokes per minute is an already relatively high speed for an arm system as described above, due to the complexity of the movement produced by the cam members;
- the amount of adhesive necessary to secure the loops to the support remains large, and therefore the products obtained are still relatively too expensive;
- the range of achievable "topped-glued" type products is relatively limited.
D'autre part, la Demanderesse a mis au point une technique de réalisation de produits textiles directement à partir de fibres et/ou filaments, qui est appelée "technique de verticalisation".On the other hand, the Applicant has developed a technique for making textile products directly from fibers and / or filaments, which is called "verticalization technique".
Cette technique est décrite dans la demande de brevet publiée sous le numéro WO91/00382, et permet directement à partir de fibres et/ou de filaments circulant sous forme d'un voile, la réalisation de produits tels que des revêtements de sols et/ou de murs de type moquette.This technique is described in the application patent published under number WO91 / 00382, and allows directly from flowing fibers and / or filaments in the form of a veil, the production of products such as carpet and / or floor coverings.
La technique décrite consiste à faire subir aux fibres et/ou aux filaments un "bouclage transversal" accompagné d'un "étirage" et à obtenir une accumulation des fibres et/ou filaments sous forme d'un "pseudo-fil" ondulé dans lequel les fibres et/ou filaments sont parallélisés. Cette étape est appelée de manière générale "étape de (pré)bouclage" et ne doit pas être assimilée à un pliage.The technique described consists in subjecting fibers and / or filaments "transverse looping" accompanied by a "stretching" and to obtain an accumulation of fibers and / or filaments in the form of a wavy "pseudo-thread" in which the fibers and / or filaments are parallelized. This step is generally called "step of (pre) looping "and should not be equated with folding.
Dans ce document, on décrit que le bouclage transversal accompagné d'étirage est réalisé pour chaque fibre ou filament individuel à l'aide d'éléments rotatifs ou disques boucleurs, espacés et disposés sur un axe transversal par rapport à la direction d'avance du voile et entre lesquels sont disposés des doigts boucleurs. De cette manière, chaque fibre ou filament est en principe impliqué dans au moins un bouclage. On constitue ainsi un pseudo-fil sans torsion obtenu par l'accumulation des diverses fibres et/ou filaments élémentaires bien parallélisés, qui présente une forme bouclée.In this document, it is described that the closure transverse accompanied by stretching is carried out for each individual fiber or filament using rotating elements or looper discs, spaced apart and arranged on an axis transverse to the direction of advance of the web and between which are curly fingers. Of this way, each fiber or filament is in principle involved in at least one loop. We thus constitute a pseudo-thread untwisted by the accumulation of various fibers and / or elementary filaments well parallelized, which has a curly shape.
L'accumulation des fibres et/ou filaments parallélisés sous forme du pseudo-fil s'effectue soit dans le chas ouvert d'aiguilles tel que cela a été décrit en détails dans la publication WO91/00382 de la Demanderesse, soit dans des encoches prévues dans des éléments de transfert comme décrit dans le document WO96/10667 également de la Demanderesse.Accumulation of fibers and / or filaments parallelized in the form of the pseudo-wire takes place either in the open eye of needles as described in details in the applicant's publication WO91 / 00382, either in notches provided in elements of transfer as described in document WO96 / 10667 also from the Applicant.
Le pseudo-fil est ensuite transporté à l'aide de ces organes de transport constitués soit par les aiguilles, soit par les éléments de transfert, sous forme de rangées transversales de boucles, vers un support auquel les boucles sont solidarisées.The pseudo-wire is then transported using of these transport components constituted either by the needles, either by the transfer elements, in the form transverse rows of loops, to a support to which the loops are joined.
Dans la publication WO91/00382, la solidarisation s'effectue par passage des aiguilles à travers ce support dans le but de réaliser plus spécifiquement un revêtement de sol de type tuft. In publication WO91 / 00382, the joining is effected by passing needles to through this support in order to achieve more specifically a tuft type flooring.
Ce procédé a encore été amélioré en proposant les perfectionnements décrits dans la demande de brevet européen EP-95870093.2, dans laquelle on combine le procédé décrit dans la publication WO91/00382 avec l'utilisation d'un étireur de nappe tel que décrit dans le document EP-A-0520911. En outre, on propose de dédoubler les éléments boucleurs en rajoutant une étape appelée "étape d'ondulation" de manière à limiter les efforts sur les arbres résultant de l'utilisation d'un voile issu d'un nappeur conventionnel.This process has been further improved by proposing the improvements described in the patent application European EP-95870093.2, in which the method is combined described in publication WO91 / 00382 with the use a web stretcher as described in the document EP-A-0520911. In addition, it is proposed to split the looping elements by adding a step called "step undulation "so as to limit the forces on the trees resulting from the use of a veil from a conventional lapper.
Dans ce cas, on a au moins deux ensembles d'éléments distincts : le premier ensemble est destiné à effectuer une étape d'ondulation à l'aide d'un dispositif constitué par l'interpénétration d'un premier jeu de disques onduleurs avec un premier jeu de doigts onduleurs, alors que le deuxième ensemble est destiné à réaliser l'étape ultérieure classique appelée étape de prébouclage à l'aide d'un dispositif constitué par l'interpénétration d'un second jeu de disques appelés disques boucleurs avec un second jeu de doigts appelés doigts boucleurs, ce second ensemble étant disposé en aval du dispositif d'ondulation par rapport à la direction d'avance du voile. La jauge du dispositif d'ondulation est un multiple de la jauge du dispositif de prébouclage.In this case, we have at least two sets separate elements: the first set is intended for perform a ripple step using a device constituted by the interpenetration of a first set of inverter discs with a first set of inverter fingers, while the second set is intended to achieve the classic subsequent step called the pre-closing step at using a device made up of interpenetration a second set of discs called looping discs with a second set of fingers called looping fingers, this second assembly being arranged downstream of the corrugation device relative to the direction of advance of the veil. The gauge of ripple device is a multiple of the gauge of the pre-loop device.
Les produits proposés dans ce document se présentent essentiellement sous forme de produits touffetés.The products offered in this document are mainly in the form of products tufted.
A ce stade, cette technique de verticalisation a pu atteindre véritablement une application industrielle. En effet, on a pu contrôler les niveaux d'efforts et de couples même dans le cas de très grandes largeurs de travail (supérieures à 4 mètres, par exemple).At this point, this technique of verticalization was able to truly reach a industrial application. In fact, we were able to control the effort and torque levels even in the case of very large working widths (greater than 4 meters, for example example).
Néanmoins, bien que ce procédé soit totalement réalisable de manière industrielle, il faut admettre que sa productivité reste encore limitée. Ceci est essentiellement dû à la présence d'organes de transport effectuant un mouvement alternatif qui se présentent soit sous forme d'aiguilles, ou encore sous forme d'éléments de transfert tels que décrits dans le document WO96/10667.However, although this process is fully achievable industrially, admit that its productivity is still limited. this is mainly due to the presence of transport devices performing a reciprocating movement which arise either in the form of needles, or in the form of elements of transfer as described in document WO96 / 10667.
En effet, la vitesse de production qui peut s'exprimer comme le produit de l'avance par coup du substrat (en mm) par la vitesse de battement des aiguilles (en coups par minute) atteint un ordre de grandeur de 1,5 à 4,5 m/min, ce qui est tout à fait admissible pour réaliser des produits touffetés mais reste encore trop faible dans le cas d'une production comparable à une ligne d'aiguilletage, dont la vitesse de production peut atteindre un ordre de 15 m/min.Indeed, the production speed which can express themselves as the product of the advance by stroke of the substrate (in mm) by the beat rate of the needles (in strokes per minute) reaches an order of magnitude of 1.5 to 4.5 m / min, which is entirely admissible to achieve tufted products but is still too weak in the case of a production comparable to a line needling, the production speed of which can reach an order of 15 m / min.
En outre, et ceci pour des raisons évidentes d'encombrement dues à la présence d'aiguilles ou même d'éléments de transfert entre les disques boucleurs, la jauge d'un dispositif dit de verticalisation pourra difficilement être inférieure à 1/10 de pouce, soit 2,54 mm, à moins de permettre la réalisation d'organes très précis et de ce fait relativement coûteux, et qui priverait le procédé dit de verticalisation de possibilité de réalisation de produits peu onéreux.In addition, and this for obvious reasons of congestion due to the presence of needles or even transfer elements between the looping discs, the gauge of a so-called verticalization device may hardly be less than 1/10 inch, or 2.54 mm, unless it allows the realization of very precise and therefore relatively expensive, and which would deprive the so-called verticalization process of possibility of making inexpensive products.
D'autre part, on note une évolution liée au goût des consommateurs vers des produits à jauge fine. Ces produits sont ceux pour lesquels l'avance par coup est la plus faible, et de ce fait la productivité également. Ainsi, on mesure l'intérêt qu'aurait un procédé pour lequel les jauges très fines seraient facilement réalisables, et ceci sans devoir limiter la vitesse de production.On the other hand, there is an evolution linked to the consumer taste for fine gauge products. These products are those for which the stroke advance is the lower, and therefore productivity too. Thus, we measure the interest that a process for which very fine gauges would be easily achievable, and this without having to limit the production speed.
La présente invention vise à proposer une solution aux limitations existantes, et plus particulièrement en ce qui concerne la productivité, dans les procédés utilisés dans la technique dite de verticalisation telle que décrite dans les documents WO91/00382 et WO96/10667.The present invention aims to provide a solution to existing limitations, and more particularly with regard to productivity, in the processes used in the technique known as verticalization as described in the documents WO91 / 00382 and WO96 / 10667.
La présente invention vise plus particulièrement à permettre la réalisation de produits dits "nappés-collés" qui peuvent présenter un aspect proche de ceux connus dans l'état de la technique tout en permettant une productivité très élevée lors de la mise en oeuvre du procédé.The present invention aims more particularly to allow the realization of products so-called "coated-glued" which may have a similar appearance of those known in the state of the art while allowing a very high productivity during the implementation process work.
La présente invention vise à titre complémentaire à permettre la réalisation de produits de type "nappé-collé" à fine jauge, c'est-à-dire présentant une jauge inférieure à 1/10 de pouce.The present invention aims as complementary to allow the realization of products of type "coated-glued" fine gauge, that is to say having a gauge less than 1/10 of an inch.
En outre, la présente invention vise à permettre la réalisation de nouveaux produits qui étaient actuellement impossibles à réaliser en utilisant la technique décrite telle quelle dans les publications antérieures de la Demanderesse, et plus particulièrement dans les publications WO91/00382 et WO96/10667.Furthermore, the present invention aims to allow the realization of new products that were currently impossible to achieve using the technique described as is in publications of the Applicant, and more particularly in publications WO91 / 00382 and WO96 / 10667.
La présente invention se rapporte à un procédé de réalisation d'un produit textile de type "nappé-collé" au départ de fibres et/ou filaments circulant dans la direction d'avance sous forme d'un voile, ce procédé comprenant au moins une étape appelée étape de prébouclage dans laquelle les fibres et/ou filaments subissent individuellement un bouclage transversalement par rapport à la direction d'avance, éventuellement accompagné d'un étirage transversal.The present invention relates to a process for producing a textile product of the "topped-glued" type from fibers and / or filaments flowing in the direction of advance in the form of a veil, this process comprising at least one step called the pre-looping step in which the fibers and / or filaments undergo individually looped transversely to advance management, possibly accompanied by a transverse stretching.
Ainsi que déjà mentionné précédemment, le bouclage transversal accompagné d'étirage est réalisé pour chaque fibre ou filament individuel à l'aide d'éléments rotatifs ou disques boucleurs espacés et disposés sur un axe transversal par rapport à la direction d'avance du voile et entre lesquels sont disposés des doigts boucleurs. Ceci permet d'obtenir que chaque fibre ou filament soit impliqué dans au moins une étape de prébouclage et permet la parallélisation de ces fibres et/ou filaments élémentaires.As already mentioned previously, the transverse looping accompanied by stretching is carried out for each individual fiber or filament using elements rotary or looper discs spaced apart and arranged on a transverse axis with respect to the direction of advance of the veil and between which are arranged looping fingers. This allows each fiber or filament to be involved in at least one pre-loop step and allows the parallelization of these fibers and / or filaments elementary.
Le présent procédé est caractérisé par le fait que l'on effectue un confinement de la matière sous forme de boucles constituées par les fibres et/ou filaments particulièrement bien parallélisés et que ce confinement se produit directement sur un support sans qu'il y ait intervention d'organes de transport tels que des aiguilles ou des éléments de transfert.The present process is characterized by that we carry out a confinement of the material under form of loops formed by fibers and / or filaments particularly well parallelized and that this confinement is produced directly on a support without there intervention of transport devices such as needles or transfer elements.
Ce confinement s'obtient après une première étape transitoire liée au démarrage d'une ligne de produit et au cours de laquelle les premières boucles obtenues par l'étape de prébouclage des fibres et/ou filaments individuels forment de manière aléatoire un arrêt. Le confinement se présente sous la forme d'une accumulation de boucles, constituées par des fibres et/ou filaments parallélisés, les unes derrière les autres.This confinement is obtained after a first transitional stage linked to the start of a product line and during which the first loops obtained by the pre-looping step of the fibers and / or filaments individual randomly form a stop. The containment comes in the form of an accumulation of loops, made up of fibers and / or filaments one behind the other.
Le positionnement des boucles successives s'effectue de manière essentiellement verticale à l'aide d'un élément détacheur, qui permet de guider la matière jusqu'au support tout en la maintenant par embarrage.The positioning of successive loops takes place essentially vertically using a detaching element, which guides the material to the support while holding it by tie-down.
Le support peut être directement le substrat final du produit que l'on désire réaliser, et de fait constitué par un mat de fibres, un film plastique, un envers de type PVC, ....The support can be directly the substrate end of the product we want to make, and in fact consisting of a fiber mat, a plastic film, a PVC type backing, ....
Eventuellement, au lieu d'être directement déposée sur le substrat du produit final, la matière confinée pourrait être saisie par un élément intermédiaire tel qu'un tapis à pointes, une brosse ou un support velcro ®, dont le rôle est de maintenir la forme ondulée des boucles pendant que l'extrémité libre de la matière est solidarisée à un substrat.Possibly, instead of being directly deposited on the substrate of the final product, the material confined could be seized by an intermediate element such as a spiked mat, a brush, or a stand velcro ®, whose role is to maintain the wavy shape loops while the free end of the material is secured to a substrate.
Cette solidarisation au substrat se fait à l'aide d'une colle dont la viscosité est étudiée pour permettre un entraínement des fibres et/ou filaments individuels de la matière avec le substrat tout en réalisant un collage efficace.This attachment to the substrate is done at using an adhesive whose viscosity is designed to allow a drive of fibers and / or filaments material with the substrate while performing an effective bonding.
De manière générale, on peut utiliser soit des plastisols, soit des résines (acryliques, isocyanates, styrène-butaniennes, phénoliques, etc.), soit des thermoplastes sous forme de hot melt, de film ou de poudre (polyesters, polypropylène, EVA PVC, etc.), soit des mousses (PVC, acryliques, etc.), soit en effectuant une adhésion directe par fusion de la fibre verticalisée sur le substrat. Les moyens utilisés pour apporter les calories nécessaires à ceci sont de préférence apportées par un four infrarouge, une calandre ou un tambour chauffant ou encore des lames chauffantes qui se présentent sous forme de pièces métalliques planes comportant des résistances électriques ou des conduits de passage de fluides caloporteurs. In general, one can use either plastisols, i.e. resins (acrylics, isocyanates, styrene-butanian, phenolic, etc.), or thermoplastics in the form of hot melt, film or powder (polyesters, polypropylene, EVA PVC, etc.), i.e. foams (PVC, acrylics, etc.), either by performing a direct adhesion by fusion of the verticalized fiber on the substrate. The means used to provide calories necessary for this are preferably brought by an oven infrared, a calender or a heating drum or heating blades which are in the form of flat metal parts with resistors electrical or heat transfer fluid conduits.
La vitesse d'avance du substrat peut soit être uniforme, soit s'effectuer par à-coups, de telle sorte que l'on obtienne un confinement de la matière textile plus marquée sur ce support.The substrate feed rate can either be uniform, or be done in spurts, so that we obtain a containment of the textile material more marked on this support.

De manière classique, un voile de fibres et/ou de filaments présentant des conditions de position des fibres et/ou filaments au sein du voile et de poids telles que décrites dans les publications antérieures de la Demanderesse est amené au niveau du dispositif de verticalisation décrit à la figure 1.Conventionally, a veil of fibers and / or filaments with position conditions fibers and / or filaments within the veil and weight as described in previous publications of the Applicant is brought to the level of the verticalization described in figure 1.
Ce dispositif comprend essentiellement un jeu
de disques appelés "disques boucleurs" portant le repère 11
et portés sur un axe commun transversal 13 entraíné en
rotation continue à une vitesse périphérique de préférence
égale à la vitesse d'entrée du voile 0. Les disques
boucleurs 11 sont pourvus sur leur périphérie d'une denture
15 présentant un angle approprié par rapport à la tangente
et qui permet l'entraínement du voile d'entrée. Entre
chacun des disques sont disposés des doigts boudeurs 21
dont l'extrémité se présente essentiellement de manière
tangentielle par rapport aux disques. Ce dispositif permet
de réaliser l'étape dite "étape de prébouclage", qui
consiste à faire subir aux fibres et/ou filaments
individuellement un bouclage transversal accompagné d'un
étirage, en vue de les paralléliser correctement.This device essentially includes a game
of discs called "looping discs" marked 11
and carried on a transverse
Afin de mieux appréhender le procédé à la base de la présente invention, il convient de se référer aux différentes figures 2a à 2e, qui décrivent les étapes successives de la préparation de la matière textile destinée à la réalisation des produits spécifiques de type nappé-collé.In order to better understand the process basis of the present invention, reference should be made in the different figures 2a to 2e, which describe the steps successive stages of the preparation of the textile material intended for the production of specific type products topped laminated.
Plus particulièrement, la figure 2a décrit
l'étape dans laquelle le voile 0 constitué des fibres et/ou
filaments 10 individuels vient d'être introduit entre les
disques boucleurs 11 et les doigts boucleurs 21. Les fibres
et/ou filaments 10 subissent individuellement l'étape de
prébouclage déjà décrite et qui correspond à un bouclage
transversal individuel éventuellement accompagné d'un
étirage. Ensuite, les fibres et/ou filaments 10
parallélisés sont amenés vers l'extrémité des doigts
boucleurs 21.More particularly, FIG. 2a describes
the step in which the veil 0 consisting of fibers and / or
individual 10 filaments have just been introduced between
looping
Selon le procédé de la présente invention et du fait de l'absence d'organes de transport tels que des aiguilles ou des éléments de transfert qui subissent un mouvement alternatif, on n'est pas limité dans le dimensionnement, et de ce fait, les efforts encaissés pourront être nettement plus importants. Ceci signifie également que les efforts subis par l'arbre pourront être plus importants, ce qui laisse une plus grande latitude dans l'orientation des fibres et/ou filaments à l'entrée du voile.According to the method of the present invention and due to the absence of transport devices such as needles or transfer elements that undergo a reciprocating, we are not limited in the dimensioning, and therefore the efforts received may be much larger. This means also that the efforts undergone by the tree could be more important, which leaves more leeway in the orientation of the fibers and / or filaments at the entrance of the sail.
La figure 2b montre que les fibres et/ou
filaments 10 qui continuent d'être entraínés par les
disques boucleurs 11 en rotation se trouvent ensuite
bloqués par la présence de pieds détacheurs 31 contre
lesquels ils commencent à s'accumuler les uns derrière les
autres en vue de former un arrêt (ou "bouchon") 20. Dans ce
cas, les fibres et/ou filaments sont fortement inclinés et
peuvent même se présenter, à la limite, de manière quasi
horizontale.Figure 2b shows that the fibers and / or
La figure 2c montre que cet arrêt ou
"bouchon" 20 a tendance à se dilater vers le bas en
direction d'un substrat 100.Figure 2c shows that this stop or
"plug" 20 tends to expand downward
direction of a
La figure 2d montre que le "bouchon" 20
constitué par l'accumulation des fibres et/ou filaments
parallélisés et ondulés finit par atteindre un volume tel
qu'il entre en contact de manière naturelle avec le
substrat 100 disposé juste sous les doigts boucleurs 21.
Dans ce cas, les fibres et/ou filaments provenant
directement de l'étape de prébouclage se condensent lors
d'une étape appelée "étape de confinement", cette fois-ci
de manière verticale, contre l'obstacle constitué par le
"bouchon".FIG. 2d shows that the "plug" 20
consisting of the accumulation of fibers and / or filaments
parallelized and wavy ends up reaching such a volume
that it comes into contact naturally with the
La figure 2e montre que le "bouchon" 20 est
entraíné par le substrat 100, aidé en cela par la rotation
des disques boucleurs 11 et par la pression exercée par les
fibres et/ou filaments 10 parallélisés qui continuent de
provenir des doigts boucleurs 21. Cette phase montre que
les fibres et/ou filaments sont ensuite déposés
régulièrement sur le substrat 100 sans qu'il n'y ait plus
d'accumulation sous forme de "bouchon". Dans ce cas, ces
fibres et/ou filaments sont disposés de manière
essentiellement verticale.Figure 2e shows that the "plug" 20 is
driven by
Selon une forme d'exécution particulièrement
préférée, on a prévu que les pieds détacheurs 31 présentent
une forme particulière en vue de faciliter cette étape. Les
pieds détacheurs sont disposé de manière à pouvoir réaliser
un entonnoir 41 entre lesdits pieds et le substrat 100 qui
continue à s'écouler.According to a particular embodiment
preferred, provision has been made for the detaching
Dans cette dernière étape, les pieds détacheurs 31 n'ont plus la fonction de détacher les fibres et/ou filaments des doigts boucleurs, mais plutôt la fonction de favoriser la solidarisation des dits fibres et/ou filaments sur le substrat. La partie arrondie des pieds détacheurs va en outre permettre de guider les fibres et/ou filaments confinés vers le substrat, alors que sa partie oblique, située à une distance du substrat légèrement inférieure à la hauteur de bouclage, va exercer une pression des fibres et/ou filaments parallélisés afin de les obliger à adhérer au support.In this last step, the feet detachers 31 no longer have the function of detaching the fibers and / or filaments of the looping fingers, but rather the function of promoting the joining of said fibers and / or filaments on the substrate. The rounded part of detaching feet will also guide the fibers and / or filaments confined to the substrate, while its oblique part, located at a distance from the substrate slightly less than the looping height, will exert a pressure of the fibers and / or filaments parallelized so to force them to adhere to the support.
La tension présente au sein des fibres et/ou
filaments au moment où ils sont confinés sur les pieds
détacheurs est inférieure à celle régnant au sein de la
matière subissant l'étape de prébouclage, ce qui permet
l'entraínement aisé des fibres et/ou filaments parallélisés
avec le substrat. En effet, si la tension subie par les
fibres et/ou filaments à l'extrémité des doigts boucleurs
lors de l'étape de prébouclage était inférieure à la
pression de réaction exercée par le "bouchon" ou arrêt dans
l'entonnoir formé par les pieds détacheurs 31 et le
substrat 100, les fibres et/ou filaments 10 commenceraient
alors à s'accumuler entre les disques boucleurs 11 et les
doigts boucleurs 21, et ceci jusqu'à l'entrée du voile. De
ce fait, il n'y aurait aucun entraínement automatique de la
matière avec le substrat.The tension present within the fibers and / or
filaments by the time they are confined to the feet
detachers is less than that prevailing within the
material undergoing the pre-looping step, which allows
easy training of parallel fibers and / or filaments
with the substrate. Indeed, if the tension undergone by
fibers and / or filaments at the end of the looping fingers
during the pre-loop step was less than the
reaction pressure exerted by the "plug" or stop in
the funnel formed by the detaching
Cette tension dépend essentiellement de l'orientation des fibres et/ou filaments dans le voile à l'entrée du dispositif de verticalisation.This tension mainly depends on the orientation of the fibers and / or filaments in the veil the entrance to the verticalization device.
L'existence de cette tension au sein des fibres et/ou filaments permet à l'ensemble de fonctionner comme un "clapet anti-retour" en évitant que les fibres et/ou filaments ne s'accumulent sur les doigts boudeurs.The existence of this tension within fibers and / or filaments allows the assembly to function as a "non-return valve" avoiding that the fibers and / or filaments do not accumulate on the sulky fingers.
Il convient de noter que bien qu'il n'y ait pas, comme décrit dans les précédentes publications de la Demanderesse, une véritable création d'un fil ou pseudo-fil, on obtient tout de même que les fibres et/ou filaments soient parfaitement parallélisés. La densité des boucles est en outre ajustable en faisant varier le rapport vitesse d'avance du substrat par rapport à la vitesse d'entraínement des disques.It should be noted that although there is not, as described in previous publications of the Applicant, a real creation of a thread or pseudo-thread, all the same, the fibers and / or filaments are obtained are perfectly parallelized. The density of the loops is also adjustable by varying the speed ratio of the substrate ahead of the speed disc drive.
En vue de réaliser les produits de type
nappés-collés, il est préférable que le substrat 100 soit
préalablement enduit d'une colle dont la viscosité aura été
choisie de manière à permettre l'entraínement des fibres
et/ou filaments 10 avec le substrat tout en réalisant un
collage efficace.In order to realize the type products
coated-glued, it is preferable that the
Eventuellement, il est envisageable de prévoir des moyens d'activation de la colle afin de la faire réagir au moment du dépôt des fibres et/ou filaments sur le substrat. Des exemples de colles telles que les colles plastisol, acryliques ou autres peuvent être bien entendu envisagés. Des dispositifs et procédés d'activation peuvent être choisis parmi les dispositifs ou procédés par contact, tels que les calandres, les lames chauffantes, etc., les dispositifs ou procédés travaillant à l'air chaud tels que les fours, les dispositifs à air pulsé, etc., ou éventuellement les dispositifs ou procédés travaillant par énergie irradiante, infrarouges, ....Possibly, it is conceivable to provide means for activating the adhesive in order to react when fibers and / or filaments are deposited on the substrate. Examples of glues such as plastisol, acrylic or other glues can be good heard contemplated. Activation devices and methods can be chosen from the devices or processes by contact, such as calenders, heating blades, etc., devices or processes working with hot air such as ovens, forced air devices, etc., or possibly the devices or processes working by irradiating, infrared energy, ....
La figure 3 représente une forme d'exécution préférée de la mise en oeuvre du procédé selon la présente invention en vue de réaliser des produits nappés-collés de type sandwich.Figure 3 shows an embodiment preferred for the implementation of the method according to the present invention with a view to producing coated-glued products of sandwich type.
Dans cette figure, on a représenté un disque
boucleur 11 sur lequel est superposé un doigt boucleur 21
dans le prolongement duquel est disposé un pied détacheur
31. Un voile 0 de fibres orientées de manière adéquate est
entraíné par une succession de disques boucleurs 11.This figure shows a
Le procédé de prébouclage et de confinement de la matière directement sur un support qui avance est réalisée de la manière décrite dans les figures 2a à 2e.The pre-loop and containment process material directly on a support which advances is performed as described in Figures 2a to 2e.
Selon la forme d'exécution représentée à la
figure 3, on effectue un dépôt de plastisol à l'aide d'une
racle 51 en vue de solidariser les boucles constituées de
fibres et/ou filaments issus de l'étape de prébouclage et
de l'étape de confinement au substrat 100. Ensuite, le
produit obtenu est soumis à un traitement thermique à
l'aide de plaques chauffantes 54 afin d'obtenir une
gélification du plastisol. Un second substrat 102 également
enduit d'un plastisol déposé à l'aide d'une racle 52 est
ensuite déposé sur le produit constitué par le premier
substrat 100 et les boucles solidarisées en vue de créer un
produit sandwich 60. Ce produit sandwich 60 est à nouveau
soumis à un traitement thermique à l'aide de plaques
chauffantes 56 afin d'obtenir la gélification du plastisol
présent sur le second substrat 102. Enfin, une lame 58
sépare en deux le produit sandwich 60 par refente afin
d'obtenir deux produits de type velours 70 et 80.According to the embodiment shown in
FIG. 3, a plastisol deposition is carried out using a
La présente invention permet de réaliser une série de produits qu'il n'était pas possible d'obtenir en utilisant les procédés et/ou dispositifs tels que décrits dans les demandes antérieures de la Demanderesse.The present invention enables a series of products which it was not possible to obtain in using the methods and / or devices as described in the Applicant's previous requests.
Trois grandes familles de produits textiles sont réalisables grâce au procédé selon la présente invention.Three main families of textile products are achievable by the method according to the present invention.
Une première grande famille comporte les revêtements de sols, de murs ou d'automobiles. En particulier, il est envisageable de réaliser un produit s'apparentant au tuft bouclé ou velours pour lequel les jauges les plus courantes sont 5/64" à 5/32". Dans ce cas, les colles utilisées seront principalement des plastisols, des PVC ou des acryliques tandis que les substrats peuvent être des tissés, des non tissés ou encore des mats de verre (dans le cas spécifique de la dalle).A first large family includes the floor, wall or automobile coverings. In particular, it is possible to realize a product akin to curly tuft or velvet for which the the most common gauges are 5/64 "to 5/32". In that case, the glues used will mainly be plastisols, PVC or acrylic while the substrates can be woven, non-woven or glass mats (in the specific case of the slab).
Il est également envisageable de réaliser des produits à aspect homogène à faible densité de velours de type aiguilleté vertical pour lesquels les jauges iront de 1/16" à 5/64". It is also possible to carry out homogeneous products with low density of velvet vertical needled type for which the gauges will go from 1/16 "to 5/64".
Finalement, les produits de faible hauteur mais forte densité de velours de type floqué peuvent être également réalisés pour des jauges inférieures à 1/16". Dans ce cas, les colles utilisées sont de préférence des thermoplastes.Finally, low-rise products but high density of flocked type velvet can be also made for gauges less than 1/16 ". In this case, the adhesives used are preferably thermoplastics.
De manière avantageuse, on observe que le dispositif utilisé pour la mise en oeuvre du procédé selon la présente invention ne comporte aucun organe sensible tel que des aiguilles ou des élément de transfert qui effectuent des mouvements alternatifs. De ce fait, on peut même utiliser des fibres naturelles grossières.Advantageously, it is observed that the device used for implementing the method according to the present invention does not include any sensitive organ such as needles or transfer elements which perform reciprocating movements. Therefore, we can even use coarse natural fibers.
Ces différents produits présentent un intérêt économique intrinsèque et des aspects fonctionnels intéressants tels que la faible sensibilité à l'humidité, la facilité d'entretien, etc.These different products are of interest intrinsic economic and functional aspects interesting things like the low sensitivity to humidity, ease of maintenance, etc.
La seconde grande famille regroupe les étoffes d'ameublement telles que les garnitures de sièges, les tentures, etc. Dans ce cas les jauges sont particulièrement faibles, de l'ordre de 1/32", et les fibres utilisées de préférence très fines. L'emploi de microfibres est même envisageable.The second large family includes upholstery such as seat upholstery, hangings, etc. In this case the gauges are particularly weak, of the order of 1/32 ", and the preferably very fine fibers used. The use of microfibers is even possible.
En particulier pour l'obtention d'un aspect suédé, on utilise une colle qui a la propriété de s'expanser jusqu'à remplir totalement l'espace entre les deux substrats d'un produit de type sandwich, telle qu'une colle de type mousse PVC, acrylique ou polyuréthane, afin d'emprisonner les fibres. L'aspect suédé est simplement obtenu par refente puis émerisage.In particular for obtaining an appearance suede, we use an adhesive that has the property of expand until completely filling the space between two substrates of a sandwich product, such as PVC, acrylic or polyurethane foam type adhesive to trap the fibers. The suede aspect is simply obtained by slitting then emery-making.
La troisième grande famille se rapporte aux textiles techniques qui présentent une structure sous forme de sandwich et qui ne sont de ce fait pas refendus. The third large family relates to technical textiles which have a structure in form sandwich and which are therefore not split.
Parmi ces textiles, on peut citer les géotextiles qui peuvent être utilisés comme structure drainante ou comme structure avec inclusion de pulvérulents de type bentonite. On peut également citer les structures panneaux, dont la rigidité est apportée par la forme sandwich, et dans lesquelles l'espace entre les deux substrats est remplie par une résine ou une mousse.Among these textiles, mention may be made of geotextiles that can be used as a structure draining or as a structure with inclusion of powders bentonite type. We can also cite the structures panels, the rigidity of which is provided by the shape sandwich, and in which the space between the two substrates is filled with a resin or foam.
Afin de mieux illustrer cette dernière famille de produits, on se référera à la figure 4, qui décrit la manière de réaliser plus précisément un produit géotextile composite avec inclusion de poudre d'argile de type bentonite.To better illustrate the latter family of products, we will refer to figure 4, which describes how to produce a product more precisely composite geotextile with inclusion of clay powder bentonite type.
Selon une forme d'exécution préférée
représentée à la figure 4, on réalise selon la présente
invention une étape de prébouclage à l'aide de disques
boucleurs 11 entre lesquels sont présents des doigts
boucleurs 21 et dans le prolongement desquels sont prévus

voile constitué dans le présent cas de fibres d'un titre
élevé, par exemple supérieur à 80 dtex, éventuellement
mélangées à des fibres plus fines, présentant par exemple
un titre de 17 dtex qui ont pour but de faciliter le
cardage du voile. Le voile 0 est entraíné entre la
succession de disques 11 et doigts boudeurs 21 en vue de
réaliser les étapes de prébouclage et de confinement tel
que décrit plus en détails à la figure 2.According to a preferred embodiment
shown in Figure 4, is carried out according to this
invention a pre-looping step using
Un substrat 104 est amené jusqu'au point de
détachage des fibres en s'appuyant sur une lame chauffante
61. Le substrat est de préférence constitué de fibres ayant
un point de fusion supérieur au point de fusion des fibres
présentes dans les boucles issues des étapes de prébouclage
et de confinement. Cette lame chauffante 61 permet
d'atteindre une température qui est supérieure à la
température de fusion des boucles, qui par contact adhèrent
directement au substrat 104 en vue d'obtenir un produit 60.A
Ensuite, de la poudre de bentonite est
déposée à l'aide d'un moyen conventionnel 63 sur le produit
60 constitué par le substrat solidarisé aux boucles.Then bentonite powder is
deposited using
L'ensemble passe ensuite sur une table
vibrante 65 en vue de favoriser la migration de la poudre
de bentonite- au sein du produit 60 pour obtenir une
distribution la plus homogène possible. Ceci est en
particulier possible du fait du titre élevé des fibres
présentes dans les boucles et de leur résilience
importante, ce qui évite qu'elles ne s'écrasent sous la
pression de la poudre. La hauteur des boucles est en outre
choisie en fonction du poids de la poudre à déposer afin
d'obtenir un espace sur la partie supérieure du produit qui
soit exempt de poudre, de telle sorte que l'on puisse y
déposer à l'aide d'une seconde lame chauffante 67 un second
substrat 105.The whole then goes on a table
vibrating 65 in order to promote the migration of the powder
of bentonite- within
On obtient ainsi une structure sandwich dans laquelle la poudre de bentonite est retenue de manière homogène.This gives a sandwich structure in which bentonite powder is retained so homogeneous.
Ces produits sont généralement utilisés en association avec des géomembranes afin d'assurer une étanchéité. En effet, en cas de présence d'un liquide, la bentonite gonfle en absorbant celui-ci et en créant de ce fait un auto-colmatage de la brèche.These products are generally used in association with geomembranes to ensure seal. Indeed, in the presence of a liquid, the bentonite swells by absorbing it and creating self-sealing the breach.
Claims (17)
- Method for producing a textile product of the lapped/bonded type from fibres and/or filaments travelling in the direction of feed motion in the form of a web, this method comprising at least one step, called the "prelooping step", in which the fibres and/or filaments individually undergo looping transversely to the direction of feed motion of the web, if appropriate accompanied by transverse drawing, characterized in that it subsequently comprises a step of confining the parallelized fibres and/or filaments in the form of loops, this latter confining step taking place directly on a support by means of a detaching element, without transport members, such as needles or transfer elements, being involved.
- Method according to claim 1, characterized in that, after a first transient step which is associated with the start-up of a line and during which the first loops obtained after the prelooping step form a stop in an arbitrary manner, confinement is obtained in the form of an accumulation of loops one behind the other, the said loops being positioned essentially vertically on the said support.
- Method according to claim 2, characterized in that the successive loops are positioned by means of a detaching element which makes it possible to guide the material as far as the support, whilst at the same time holding the said material by means of a bar assembly.
- Method according to any one of the preceding claims, characterized in that the support is the substrate of the final product.
- Method according to any one of the claims 1 to 3, characterized in that the support is an intermediate element, such as a spiked belt, a brush or else a Velcro ® support, the function of which is to maintain the crimped form of the loops while the free end of the material is being fixed to a substrate.
- Method according to claim 4 or 5, characterized in that the loops are fixed to the substrate by means of a glue, the viscosity of which makes it possible to drive the loops, together with the substrate, whilst at the same time carrying out efficient bonding.
- Method according to claim 4 or 5, characterized in that the loops are fixed to the substrate with the aid of heating means, such as a furnace, a calender, a drum or a heating blade, in order to obtain adhesion of the loops to the substrate by melting.
- Method according to any one of the preceding claims, characterized in that the feed speed of the support is uniform or takes place in bursts.
- Method according to any one of the preceding claims, characterized in that a second substrate is deposited onto the product comprising the basic substrate and the fixed loops, in order to produce a sandwich product.
- Method according to claim 9, characterized in that the sandwich product is split in order to obtain two products in the form of pile fabric.
- Method according to claim 9, characterized in that a powdery material, such as bentonite, chalk or sand, is introduced into the sandwich structure consisting of the two substrates, if appropriate accompanied by solid elements, such as pipes or cables.
- Device for carrying out the method according to any one of the preceding claims, comprising a set of discs (11) which are carried on a common transverse shaft (13) and are driven in continuous rotation and which are provided, on their periphery, with a toothing (15) which has an angle relative to the tangent and between which are arranged looping fingers (21), the ends of which are presented essentially tangentially relative to the discs, characterized in that it possesses, furthermore, in the extension of each looping finger (21), a detaching foot (31).
- Product obtained by means of the method according to any one of claims 1 to 11 or the device according to claim 12, characterized in that it comprises a first substrate, to which loops of parallelized fibres and/or filaments are fixed, without the said loops passing through the substrate, the loops being capable, if appropriate, of being sheared during a subsequent step, the gauge being less than 1/10th of an inch, preferably less than 1/16th of an inch.
- Product according to claim 13, characterized in that the gauge is less than 1/32th of an inch.
- Product according to claim 13 or 14, characterized in that the loops are fixed to the substrate either by melting or with the aid of a glue.
- Product according to any one of the claims 13 to 15, characterized in that a second substrate is arranged on top of the assembly consisting of the first substrate and of the fixed loops, in order to produce a sandwich structure.
- Product according to claim 16, characterized in that it comprises, in the sandwich structure consisting of the two substrates, a powdery material, such as bentonite, included between the two substrates.
