Description

La présente invention a pour objet un fil composite de type bouclette, un procédé pour la fabrication d'un tel fil et des produits de récurage contenant dans leur structure au moins un tel fil.The subject of the present invention is a loop-like composite yarn, a method for manufacturing such a yarn and scouring products containing in their structure at least one such yarn.

Elle concerne plus particulièrement un tel fil et son utilisation pour l'élaboration de produits de récurage (ou produits abrasifs).It relates more particularly to such a wire and its use for the preparation of scouring products (or abrasive products).

L'utilisation de fils selon l'invention permet l'élaboration de produits récurants présentant un très fort pouvoir abrasif si l'on fait intervenir un métal au niveau des bouclettes ; un pouvoir abrasif plus ou moins fort si l'on utilise d'autres matériaux à ce niveau. Ceci est explicité plus avant dans le présent texte.The use of threads according to the invention allows the preparation of scouring products having a very high abrasive power if a metal is used at the loops; more or less strong abrasive power if other materials are used at this level. This is explained further in this text.

Le fil de l'invention est du type de celui intervenant dans la structure de l'étoffe récurante décrite dans le brevet US-A-2 026 632. Dans ledit brevet, le fil composite intervenant comprend une âme en un matériau textile naturel tel que le coton, autour de laquelle est enroulée, de manière lâche, selon une hélice, une lame métallique, en cuivre par exemple.The yarn of the invention is of the type used in the structure of the scouring fabric described in patent US-A-2 026 632. In said patent, the intervening composite yarn comprises a core made of a natural textile material such as cotton, around which is loosely wound, according to a propeller, a metal blade, made of copper for example.

Le fil composite de l'invention comprend également une âme autour de laquelle est enroulée, à distance, de manière flottante, au moins un fil, selon une hélice à spires non jointives. Ledit fil, en vue d'exercer une action abrasive, présente au moins une arête vive. De façon caractéristique, on a modifié, selon l'invention, la structure de ladite hélice, pour renforcer le pouvoir abrasif du fil la constituant. Pour une telle modification, on a du mettre au point un procédé spécifique de guipage dudit fil autour de l'âme.The composite wire of the invention also comprises a core around which is wound, at a distance, in a floating manner, at least one wire, according to a helix with non-contiguous turns. Said wire, in order to exert an abrasive action, has at least one sharp edge. Characteristically, the structure of said propeller has been modified according to the invention in order to reinforce the abrasive power of the wire constituting it. For such a modification, we had to develop a specific process for wrapping said wire around the core.

De façon caractéristique, les spires de l'hélice sont réparties le long de l'âme de façon irrégulière, tantôt étirées, tantôt ramassées sur elles-mêmes pour former des bouclettes. Le fil enroulé autour de l'âme selon une hélice à spires non jointives se présente donc sous une forme irrégulière. Le long de sa longueur, il se présente tantôt selon une hélice à "grand" pas, tantôt selon un amas de spires (bouclettes).Characteristically, the turns of the propeller are distributed along the core in an irregular manner, sometimes stretched, sometimes picked up on themselves to form loops. The wire wound around the core in a helix with non-contiguous turns is therefore in an irregular shape. Along its length, it sometimes appears in a "large" pitch propeller, sometimes in a heap of turns (loops).

La présence de ces bouclettes constitue l'une des originalités des fils composites selon l'invention et des produits de récurage incluant, dans leur structure, lesdits fils.The presence of these loops constitutes one of the originalities of the composite wires according to the invention and of the scouring products including, in their structure, said wires.

Le fil enroulé autour de l'âme présente au moins une arête vive. Il peut être de forme quelconque. Il consiste avantageusement en une lame.The wire wound around the core has at least one sharp edge. It can be of any shape. It advantageously consists of a blade.

Ledit fil est en un matériau dur. Un tel matériau est avantageusement choisi parmi les matériaux métalliques, les plastiques métallisés, les plastiques durs. Ledit fil peut notamment être élaboré :

  • en acier inoxydable, en cuivre, en maillechort, en aluminium...
  • en polyester métallisé avec de l'aluminium...
  • en polyamide, polyester...
Said wire is made of a hard material. Such a material is advantageously chosen from metallic materials, metallized plastics, hard plastics. Said thread can in particular be produced:
  • stainless steel, copper, nickel silver, aluminum ...
  • polyester metallized with aluminum ...
  • polyamide, polyester ...

Ledit fil consiste avantageusement en une lame métallique résistant à l'eau de Javel.Said wire advantageously consists of a metal blade resistant to bleach.

Comme indiqué ci-dessus, on n'exclut nullement dans la structure des fils composites de l'invention l'intervention de plusieurs desdits fils, enroulés autour d'une même âme, lesdits fils étant en un même matériau ou en des matériaux différents.As indicated above, the structure of the composite yarns of the invention is in no way excluded from the intervention of several of the said yarns, wound around the same core, the said yarns being of the same material or of different materials.

L'âme des fils composites de l'invention peut comporter un ou plusieurs fils. De tels fils peuvent notamment être choisis parmi les fils en matière textile naturelle telle que le coton, les fils en matière textile artificielle telle que la viscose, les fils métalliques, les fils en matière plastique telle que le polypropylène, le polyester, le polyamide... Avantageusement, ladite âme comporte au moins deux fils en des matériaux différents dont au moins l'un est thermofusible, tandis que l'autre (ou les autres) est (sont) plus résistant(s) en température. Selon une variante préférée, ladite âme consiste en deux fils en matière plastique, l'un en polypropylène, l'autre en polyamide ou polyester.The core of the composite yarns of the invention can comprise one or more yarns. Such threads can in particular be chosen from threads made of natural textile material such as cotton, threads made of artificial textile material such as viscose, metallic threads, threads made of plastic material such as polypropylene, polyester, polyamide. .. Advantageously, said core comprises at least two wires made of different materials, at least one of which is hot-melt, while the other (or the others) is (are) more resistant (s) in temperature. According to a preferred variant, said core consists of two plastic wires, one of polypropylene, the other of polyamide or polyester.

On comprendra aisément l'intérêt de cette combinaison : fil(s) thermofusible(s)/fil(s) plus résistant(s) en température au sein de l'âme des fils composites de l'invention à la lecture de ce qui suit. On précise d'ores et déjà que la thermofusibilité d'au moins un des fils de l'âme permet de créer des liaisons, par collage, au sein de produits de récurage renfermant des fils composites, selon l'invention. De telle liaisons peuvent également être obtenues par soudage, soudage faisant intervenir au moins un fil métallique de l'âme et/ou un fil métallique enroulé en hélice autour de ladite âme.We can easily understand the advantage of this combination: hot-melt wire (s) / wire (s) more temperature-resistant (s) within the core of the composite wires of the invention on reading the following . It is already specified that the thermofusibility of at least one of the wires of the core makes it possible to create bonds, by gluing, within scouring products containing composite wires, according to the invention. Such connections can also be obtained by welding, welding involving at least one metal wire of the core and / or a metal wire wound helically around said core.

Selon un autre de ses aspects, l'invention concerne un procédé pour la fabrication d'un fil composite tel que décrit ci-dessus.According to another of its aspects, the invention relates to a method for the manufacture of a composite wire as described above.

On obtient un tel fil selon une technique du type guipage. Le guipage est en lui-même un procédé connu. On a notamment décrit dans la demande de brevet FR-A-2 670 806 un dispositif pour une certaine mise en oeuvre de oelui-ci. Selon l'invention, le guipage est mis en oeuvre de façon caractéristique en faisant intervenir une aiguille. On fait défiler le ou les fils destiné(s) à constituer l'âme des fils composites selon l'invention le long de ladite aiguille et l'on guipe autour de l'ensemble aiguille/âme le ou les fil(s) présentant chacun au moins une arête vive, générant ainsi autour de ladite âme une ou des hélice(s) à pas irrégulier. L'âme défile, au cours dudit guipage, maintenue sous une certaine tension, de manière adjacente à l'aiguille. Du fait du manque de glissement des spires de l'hélice ou des hélices générée(s) sur l'aiguille, lesdites spires se dégagent, sous la tension, par paquets et c'est ainsi que se génèrent les bouclettes.Such a wire is obtained according to a technique of the wrapping type. The wrapping is in itself a known process. In particular, there has been described in patent application FR-A-2 670 806 a device for a certain implementation thereof. According to the invention, the wrapping is implemented typically by involving a needle. We scroll through the thread (s) intended to constitute the core of the composite yarns according to the invention along said needle and the yarn (s) is (are) wrapped around the needle / core assembly, each having at least one sharp edge, thus generating around said core a or propellers with irregular pitch. The core scrolls, during said wrapping, maintained under a certain tension, adjacent to the needle. Due to the lack of sliding of the turns of the propeller or of the propellers generated (s) on the needle, said turns are released, under tension, in bundles and this is how the loops are generated.

De façon avantageuse, ladite aiguille présente une extrémité conique et le guipage du ou desdits fil(s) est mis en oeuvre au niveau de ladite extrémité conique.Advantageously, said needle has a conical end and the covering of the said thread (s) is implemented at the level of said conical end.

L'aiguille utilisée est généralement en métal.The needle used is generally made of metal.

C'est donc grâce à cette aiguille que les bouclettes sont obtenues et que les fils composites de l'invention présentent plusieurs arêtes vives, leur permettant d'exercer une forte action abrasive, une fois lesdits fils composites disposés sur un support approprié ou enroulés sur eux-mêmes.It is therefore thanks to this needle that the loops are obtained and that the composite yarns of the invention have several sharp edges, allowing them to exert a strong abrasive action, once said composite yarns are placed on a suitable support or wound on themselves.

La présente invention a également pour objets l'utilisation de tels fils composites pour l'élaboration de produits récurants et lesdits produits récurants per se.The present invention also relates to the use of such composite yarns for the preparation of scouring products and said scouring products per se.

Les produits de récurage selon l'invention incluent donc dans leur structure au moins un fil composite tel que décrit ci-dessus. Ils ont en tout état de cause, été élaborés en utilisant au moins un tel fil.The scouring products according to the invention therefore include in their structure at least one composite wire as described above. In any case, they were developed using at least one such thread.

On peut retrouver dans lesdits produits de récurage le fil composite original ou modifié, suite à un traitement visant à créer des liaisons au sein de la structure desdits produits.One can find in said scouring products the original or modified composite yarn, following a treatment aimed at creating bonds within the structure of said products.

Ces liaisons peuvent notamment résulter de soudage et/ou collage mettant à profit la nature des matériaux intervenants : métal et/ou matériau thermofusible. Ces liaisons renforcent encore le pouvoir abrasif des produits de récurage au sein desquels elles interviennent. Elles stabilisent également leur structure.These connections can in particular result from welding and / or bonding taking advantage of the nature of the materials involved: metal and / or hot-melt material. These bonds further reinforce the abrasive power of the scouring products in which they operate. They also stabilize their structure.

L'homme du métier réalisera aisément à la lecture de ce qui suit l'intérêt de ces liaisons.Those skilled in the art will readily realize on reading the following the interest of these links.

Les produits de récurage selon l'invention peuvent exister selon différentes formes et notamment sous la forme de tampons, de nappes, de combinés, disques ou patins récurants incluant de telles nappes dans leur structure. Ils sont utiles pour récurer et/ou abraser des surfaces métalliques, des parquets, des surfaces en béton...The scouring products according to the invention can exist in different forms and in particular in the form of pads, plies, combined, scouring discs or pads including such plies in their structure. They are useful for scouring and / or abrading metal surfaces, parquet floors, concrete surfaces ...

Selon une première variante, les produits de récurage selon l'invention consistent en des tampons qui se présentent sous la forme de pelotes, obtenues par enroulement d'au moins un fil composite. On peut par exemple bobiner un tel fil autour d'un mandrin puis éjecter ledit mandrin. Avantageusement, lesdites pelotes présentent dans leur structure des liaisons par collage et/ou soudage. De telles liaisons augmentent la cohésion, la rigidité du tampon et par là même son pouvoir décrassant. Ces liaisons peuvent être générées par différentes techniques et notamment par soudage. On peut réaliser ponctuellement des soudures ou des brasures en faisant intervenir au moins un fil métallique enroulé autour de l'âme ; ladite âme comportant éventuellement au moins un autre fil métallique.According to a first variant, the scouring products according to the invention consist of pads which are in the form of balls, obtained by winding at least one composite wire. One can for example wind such a wire around a mandrel and then eject said mandrel. Advantageously, said balls have in their structure bonds by bonding and / or welding. Such connections increase the cohesion, the rigidity of the buffer and thereby its scouring power. These connections can be generated by different techniques and in particular by welding. Welds or solders can be made punctually by using at least one metal wire wound around the core; said core possibly comprising at least one other metallic wire.

Ces liaisons peuvent également, selon une variante préférée, résulter de la fusion d'au moins un fil thermofusible de l'âme. Pour les générer, on fait passer le produit dans un four, à une température et pendant une durée suffisantes pour assurer la fusion dudit matériau thermofusible. La création de telles liaisons fait pratiquement disparaître un fil de l'âme du fil composite. C'est pourquoi, l'on utilise avantageusement au départ une âme multi-fils.These connections can also, according to a preferred variant, result from the fusion of at least one hot-melt wire of the core. To generate them, the product is passed through an oven, at a temperature and for a time sufficient to ensure the melting of said hot-melt material. The creation of such connections practically disappears a wire from the core of the composite wire. This is why, a multi-son core is advantageously used at the start.

On n'exclut pas, selon l'invention, de générer au sein d'un tampon à la fois des soudures et des points de collage.It is not excluded, according to the invention, to generate within a buffer both welds and bonding points.

Selon une autre variante, les produits de récurage de l'invention consistent en des nappes comprenant un support et au moins un fil composite de l'invention, inséré et pris, avantageusement régulièrement dans ledit support ; des liaisons par collage et/ou soudage existant avantageusement entre ledit support et le(s)dit(s) fil(s) composite(s) et/ou entre lesdits fils composites.According to another variant, the scouring products of the invention consist of sheets comprising a support and at least one composite wire of the invention, inserted and taken, advantageously regularly in said support; bonding and / or welding connections advantageously existing between said support and said composite wire (s) and / or between said composite wires.

Ledit support peut être de tout type. Il comporte au moins un fil de support et peut notamment être obtenu par tricotage.Said support can be of any type. It comprises at least one support wire and can in particular be obtained by knitting.

Selon cette variante de l'invention, on incorpore donc des fils composites dans un support, par exemple tissé ou tricoté. Un tel support peut notamment consister en un tricot présentant une maille de type jersey, par exemple une maille jersey vanisé.According to this variant of the invention, composite yarns are therefore incorporated in a support, for example woven or knitted. Such a support may in particular consist of a knitted fabric having a jersey-type mesh, for example a vanized jersey mesh.

La nature des matériaux entrant dans la composition dudit support doit évidemment, si l'on souhaite créer des liaisons au sein de la structure support/fil(s) composite(s), être compatible avec les traitements générant lesdites liaisons.The nature of the materials used in the composition of said support must obviously, if one wishes to create connections within the support structure / composite wire (s), be compatible with the treatments generating said connections.

Ledit support peut notamment renfermer de la cellulose, des fils métalliques, des fils de polyester et/ou polyamide...Said support may in particular contain cellulose, metallic threads, polyester and / or polyamide threads, etc.

Comme dans le cas des tampons précédemment décrits, on peut donc avantageusement créer au sein de ladite structure support/fil(s) composite(s) des liaisons. Ces liaisons peuvent être obtenues par collage et/ou soudage de matériaux entrant dans la composition des fils composites et éventuellement dans la composition du support. Ainsi, par fusion d'un fil thermofusible entrant dans la composition de l'âme de fils composites, on peut lier ceux-ci au support. La liaison sera encore plus forte si elle met aussi en jeu au moins un fil thermofusible du support. Au sein de nappes récurantes selon l'invention, on trouve donc avantageusement des liaisons résultant de la fusion de fil(s) thermofusible(s) présent(s) dans la structure des fils composites intervenants et/ou dans la structure du support. On peut, selon une variante, faire intervenir un fil thermofusible du même type dans l'âme des fils composites et dans le support et, par fusion dudit fil thermofusible, solidariser parfaitement lesdits fils composites audit support.As in the case of the buffers described above, it is therefore advantageous to create within said support structure / composite wire (s) connections. These connections can be obtained by bonding and / or welding of materials used in the composition of the composite wires and optionally in the composition of the support. Thus, by melting a hot-melt wire used in the composition of the core of composite wires, these can be linked to the support. The bond will be even stronger if it also involves at least one hot-melt wire of the support. Within scouring layers according to the invention, there are therefore advantageously connections resulting from the fusion of hot-melt wire (s) present in the structure of the composite son involved and / or in the structure of the support. One can, according to a variant, involve a hot-melt wire of the same type in the core of the composite wires and in the support and, by melting said hot-melt wire, perfectly joining said composite wires to said support.

Ledit support peut par exemple consister en une nappe tricotée et l'incorporation de fils composites en son sein peut se faire à chaque rangée ou toutes les 2, 3, 4... rangées.Said support can for example consist of a knitted sheet and the incorporation of composite threads within it can be done in each row or every 2, 3, 4 ... rows.

Ledit support peut être avantageusement obtenu par tricotage d'un fil double de support constitué d'un fil avant thermofusible et d'un fil de fond plus résistant en température et ledit fil composite constituer un fil de chaîneuse dudit tricot ; ledit fil composite comportant dans son âme un fil thermofusible présentant une température de fusion inférieure à ou voisine de celle dudit fil avant. La fusion desdits fils thermofusibles est assurée par traitement thermique adéquat de la nappe obtenue après incorporation du fil composite dans le support.Said support can advantageously be obtained by knitting a double support wire consisting of a hot-melt front wire and a bottom wire more resistant to temperature and said composite wire constituting a chain thread of said knitted fabric; said composite wire comprising in its core a hot-melt wire having a melting temperature lower than or close to that of said front wire. The melting of said hot-melt wires is ensured by adequate heat treatment of the sheet obtained after incorporation of the composite wire into the support.

L'intervention de fil(s) thermofusible(s) dans la structure de nappes récurantes selon l'invention permet donc, par un traitement thermique approprié, de solidariser plus efficacement le support et les fils composites insérés dans celui-ci. Ceci influe, sur le pouvoir récurant du produit fini et sur sa stabilité, surtout au niveau de ses bords. On évite ainsi, en tout état de cause ou limite très fortement, les phénomènes d'effilochage.The intervention of hot-melt wire (s) in the structure of scouring plies according to the invention therefore makes it possible, by appropriate heat treatment, to more effectively secure the support and the composite wires inserted therein. This influences the scouring power of the finished product and its stability, especially at its edges. This avoids, in any event or very strongly limits, the fraying phenomena.

A cette même fin, on peut prévoir de recouvrir les bords de telles nappes d'une pellicule de matériau thermofusible, que l'on fait fondre à la température adéquate. Cette étape supplémentaire du procédé est a priori superflue avec des nappes liées. Elle n'est toutefois pas écartée du cadre de l'invention.To the same end, provision may be made to cover the edges of such plies with a film of hot-melt material, which is melted at the appropriate temperature. This additional step of the process is a priori superfluous with linked plies. However, it is not excluded from the scope of the invention.

On a insisté ci-dessus sur les liaisons par collage, résultant de la fusion d'au moins un matériau thermofusible présent dans la structure support/fil(s) composite(s).We have stressed above the bonding by bonding, resulting from the fusion of at least one hot-melt material present in the support structure / composite wire (s).

L'homme du métier comprendra que les mêmes effets peuvent être obtenus en générant des liaisons par soudage entre des métaux entrant dans la composition des fils composites, notamment au croisement de deux fils de ce type et/ou des métaux entrant dans la composition du support.Those skilled in the art will understand that the same effects can be obtained by generating bonding by welding between metals entering the composition of the composite wires, in particular at the crossing of two wires of this type and / or of the metals used in the composition of the support.

On n'exclut pas, par ailleurs, de générer au sein des nappes récurantes à la fois des soudures et des points de collage.It is not excluded, moreover, to generate within the scouring plies both welds and bonding points.

A la lecture des propos ci-dessus, on réalisera par ailleurs tout l'intérêt des fils composites de l'invention qui se caractérisent donc par leur aspect bouclette et par leur structure qui permet au sein d'un matériau de figer plus ou moins lesdites bouclettes.On reading the above remarks, one will also realize all the interest of the composite yarns of the invention which are therefore characterized by their curly appearance and by their structure which allows, within a material, to more or less freeze said said curls.

Selon une autre variante, les produits de récurage de l'invention consistent en des combinés récurants comprenant une éponge ou une mousse synthétique, par exemple une mousse de polyuréthanne, sur au moins une face de laquelle est collée une nappe récurante, telle que décrite ci-dessus ou encore en des disques de ponçage comprenant un support sur lequel est collée une telle nappe récurante.According to another variant, the scouring products of the invention consist of scouring combinations comprising a sponge or a synthetic foam, for example a polyurethane foam, on at least one face of which a scouring sheet is bonded, as described below. above or in sanding discs comprising a support on which is glued such a scouring sheet.

On insistera ici sur les avantages que présentent les produits récurants de l'invention et tout particulièrement sur ceux des combinés récurants associant une éponge ou équivalent à une nappe récurante.We will insist here on the advantages of the scouring products of the invention and very particularly on those of scouring handsets associating a sponge or equivalent with a scouring sheet.

De tels combinés offrent une excellente prise en main, évitent le contact des mains de l'utilisateur avec la surface à récurer, et ont un pouvoir décrassant maximum. Par ailleurs, on peut optimiser la densité de fil sur la surface de l'éponge et limiter ainsi le problème du colmatage par les saletés.Such handsets offer an excellent grip, avoid contact of the user's hands with the scouring surface, and have maximum cleaning power. Furthermore, it is possible to optimize the density of yarn on the surface of the sponge and thus limit the problem of clogging by dirt.

L'invention est illustrée par les dessins annexés :

  • la figure 3 représente, à échelle agrandie, la maille élémentaire d'un support, pour nappes récurantes selon l'invention ;
  • la figure 4 schématise, à échelle agrandie, une nappe récurante selon l'invention.
The invention is illustrated by the accompanying drawings:
  • Figure 1 shows, on an enlarged scale, a composite yarn according to the invention;
  • FIG. 2 schematically represents the method of obtaining a composite wire according to the invention;
  • FIG. 3 represents, on an enlarged scale, the elementary mesh of a support, for scouring sheets according to the invention;
  • Figure 4 shows schematically, on an enlarged scale, a scouring sheet according to the invention.

La figure 1 montre un fil composite 1 selon l'invention. Il comprend une âme 2 comportant deux fils 2a, 2b. Le fil 2a peut être en polypropylène (fusible vers 170°C), le fil 2b en polyester (stable à 170°C ; fusible vers 240°C). Ladite âme 2 est entourée par une lame métallique 3 selon une hélice. Les spires 4 de ladite hélice sont non jointives et sont réparties le long de ladite âme 2 de façon irrégulière. Lesdites spires 4 sont tantôt étirées 4a, tantôt ramassées sur elles-mêmes pour former des bouclettes 4b. Lesdites spires 4 entourent ladite âme 2 de manière flottante.Figure 1 shows a composite wire 1 according to the invention. It comprises a core 2 comprising two wires 2a, 2b. The wire 2a may be made of polypropylene (fuse around 170 ° C), the wire 2b of polyester (stable at 170 ° C; fuse around 240 ° C). Said core 2 is surrounded by a metal blade 3 according to a helix. The turns 4 of said propeller are non-contiguous and are distributed along said core 2 irregularly. Said turns 4 are sometimes stretched 4a, sometimes picked up on themselves to form loops 4b. Said turns 4 surround said core 2 in a floating manner.

Conformément à la figure 2, un tel fil 1 est obtenu par guipage. L'âme 2 défile contre une aiguille fixe 5 et la lame métallique 3 est guipée autour de l'ensemble : âme 2/aiguille 5. Ladite aiguille 5 présente une extrémité conique 5a. En 20, on a représenté la tête de guipage dans l'axe de laquelle circule l'âme textile 2 et est fixée l'aiguille 5. Sur ladite tête de guipage 20 est montée une bobine 21 susceptible de débiter la lame métallique 3. La tête de guipage 20 est animée d'un mouvement de rotation autour de l'âme 2, de manière à déposer en hélice ladite lame 3 autour de ladite âme 2. Les spires métalliques 4 se dégagent par paquet 4b de l'extrémité Sa de l'aiguille, du fait du manque de glissement de la lame métallique 3 sur ladite aiguille 5.According to Figure 2, such a wire 1 is obtained by wrapping. The core 2 travels against a fixed needle 5 and the metal blade 3 is wrapped around the assembly: core 2 / needle 5. Said needle 5 has a conical end 5a. At 20, the covering head is shown in the axis of which the textile core 2 circulates and the needle is fixed 5. On said covering head 20 is mounted a coil 21 capable of delivering the metal blade 3. The covering head 20 is driven in a rotational movement around the core 2, so as to helically deposit said blade 3 around said core 2. The metal turns 4 are released by package 4b from the end Sa of l 'needle, due to the lack of sliding of the metal blade 3 on said needle 5.

Sur la figure 3, on a représenté en 8 un fil double de support pour nappes récurantes selon l'invention. Ledit fil double est constitué d'un fil de fond 8a et d'un fil avant ou fil de liaison 8b thermofusible. Ledit fil avant 8b peut être en polypropylène. Les deux fils 8a et 8b sont tricotés en parallèle suivant le principe du vanisé, pour obtenir un tricot tel que représenté en 11 sur la figure 4.In Figure 3, there is shown at 8 a double support wire for scouring sheets according to the invention. Said double wire consists of a bottom wire 8a and a front wire or thermofusible connecting wire 8b. Said front wire 8b can be made of polypropylene. The two threads 8a and 8b are knitted in parallel according to the principle of vanity, to obtain a knit as shown at 11 in FIG. 4.

Sur la figure 4, on a schématisé une nappe récurante selon l'invention, à base d'un tricot 11 formant support. Ledit tricot 11 est obtenu par tricotage du fil double de support 8. Dans ledit tricot 11, on a entrelacé sous forme de fils de chaîneuse une pluralité de fils composites 1 selon l'invention. Chaque fil composite 1 se trouve pris, régulièrement selon sa longueur, dans le tricot 11. Les fils avant ou fil de liaison 8b du tricot 11 et l'âme 2 desdits fils composites 1 sont liés les uns aux autres par fusion de leurs matériaux thermofusibles (ici, par exemple, un seul et même matériau thermofusible : le polypropylène) selon des "points" de liaison 10. Ces "points" de liaison 10 emprisonnent et noient les fils métalliques. Ils stabilisent la nappe.(On notera qu'en réalité, pratiquement, l'intégralité des fils 8b a fondu).In Figure 4, there is shown schematically a scouring sheet according to the invention, based on a knitted fabric 11 forming a support. Said knit 11 is obtained by knitting the double support thread 8. In said knit 11, a plurality of composite threads 1 according to the invention have been interlaced in the form of warp threads. Each composite yarn 1 is taken, regularly along its length, in the knitted fabric 11. The front yarns or connecting thread 8b of the knitted fabric 11 and the core 2 of said composite yarns 1 are bonded to each other by fusion of their hot-melt materials (here, for example, one and the same hot-melt material: polypropylene) according to "points" of connection 10. These "points" of connection 10 trap and drown the metal wires. They stabilize the sheet (Note that in reality, practically, all of the wires 8b have melted).

A titre d'exemple, on précise ci-après la structure d'un fil composite selon l'invention.By way of example, the structure of a composite wire according to the invention is specified below.

Son âme est constituée de deux fils multibrins : l'un en polyproylène 550 décitex, l'autre en polyester 1100 décitex.Its core is made up of two multi-strand threads: one in 550 decitex polyproylene, the other in 1100 decitex polyester.

Autour de ladite âme, on a guipé une lame métallique en acier Inox. Son épaisseur est de 8 à 10 centièmes de mm, sa largeur de 45 à 50 centièmes de mm. Les spires de l'hélice obtenue ont un diamètre qui varie de 1,8 à 2,5 mm.Around the said core, a stainless steel metal blade was wrapped. Its thickness is 8 to 10 hundredths of a mm, its width from 45 to 50 hundredths of a mm. The turns of the propeller obtained have a diameter which varies from 1.8 to 2.5 mm.

De tels fils sont avantageusement entrelacés sous forme de fils de chaîneuse dans les entremailles d'un tricot : polypropylène/polyester (PP, PE tels que caractérisés ci-dessus). Le tout est apprêté thermiquement vers 200°C pendant environ 5 min. On obtient ainsi une nappe récurante que l'on peut contrecoller sur une éponge ou une mousse polyuréthanne. On a ainsi réalisé un combiné récurant à fort pouvoir abrasif, qui offre une bonne prise en main.Advantageously, such threads are interlaced in the form of warp threads in the interlacing of a knitted fabric: polypropylene / polyester (PP, PE as described above). The whole is thermally primed at around 200 ° C. for approximately 5 min. This gives a scouring sheet that can be laminated on a sponge or polyurethane foam. We thus achieved a scouring handset with high abrasive power, which offers a good grip.
