Abstract

A prefabricated construction material comprises at least one non-woven textile material of synthetic continuous filaments, which may be needled and singed, and a plastic support material, which may be loaded. The plastic support material may be injection moulded in a mould where at least one of the internal surfaces is covered with one or more layers of the non-woven textile. Non-woven fabrics of melt-spun fibres when used for mouldings of this kind provide an isotropy, deforming well in stress zones, with no thin places. Folds do not occur in the moulding, nor bursting in the relief zones. Such fabrics have good resistance to abrasion, light, ageing, heat and cleaning. The pre-fabricated construction element is obtained in a single operation. The pre-fabricated construction elements are used for building, domestic appliances and for furniture, etc.

Description

La présente demande a pour objet des éléments habillés préfabriqués de construction et leurs procédés de fabrication. The present application relates to prefabricated dressed construction elements and their manufacturing processes.

Les éléments préfabriqués de construction tels que ceux utilisés par exemple dans la construction de moyen de transport, dans le bâtiment, l'électro-ménager, l'ameublement, nécessitent parfois un habillage d'un revêtaient textile sur au moins une de leurs faces pour des raisons de confort, d'esthétique et d'intégration de processus de réalisation pour simplifier celui- ci. Prefabricated construction elements such as those used for example in the construction of means of transport, in building, household appliances, furniture, sometimes require a covering of a textile coating on at least one of their faces to reasons of comfort, aesthetics and integration of the production process to simplify it.

Ainsi, pour le garnissage intérieur de moyens de transport par eau, air, terre, tels qu'automobiles, wagons de chemins de fer, bateaux, cars, canyons, avions, que ces moyens de tranport servent pour du personnel ou des marchandiscs, il est connu de faire appel à un habillage intérieur en textile, cuir ou imitation posés selon des méthodes de sellerie longues et onéreuses. Récemment, il a été proposé d'associer du tricot k des pièces moulées lors du moulage de ces dernières.Toutefois, le tricot n'est généralesent extensible que dans un sens et les déforiations dues au moulage en particulier dans les zones très sollicitées telles que coins, Creux, etc , provoquent des points faibles, fragiles à l'éclatement, et des plis préjudiciables à l'aspect du produit fini. On a aussi songé à utiliser des textiles non-tissés réalisés à partir de fibres par voie sèche ou humide Toutefois, ces non-tissés ont une déforiabilité faible et une résistance à la rupture relative qui ne tonnent pas de bons résultats.Dans le bâtiment, la réalisation de cloisons préfabriquées facilite la construction ais il faut y ajouter ensuite une revêteioent, ce qui nécessite d'autres opérations. Thus, for the interior lining of means of transport by water, air, land, such as cars, railroad cars, boats, coaches, canyons, planes, whether these means of transport are used for personnel or merchants. is known to use an interior covering in textile, leather or imitation posed according to long and expensive upholstery methods. Recently, it has been proposed to combine knitting with molded parts during the molding of the latter. However, knitting is generally only stretchable in one direction and the deformations due to molding in particular in highly stressed areas such as corners, Hollow, etc., cause weak points, fragile at bursting, and folds detrimental to the appearance of the finished product. Consideration has also been given to using non-woven textiles produced from fibers by the dry or wet method. However, these non-wovens have a low deforability and a relative breaking strength which do not give good results. the production of prefabricated partitions facilitates construction, but a coating must then be added thereto, which requires other operations.

La présente demande se propose d'éviter les inconvénients des habillages textiles antérieurement proposés. The present application proposes to avoid the drawbacks of the textile covers previously proposed.

La présente invention a pour objet des éléments habillés préfabriqués de construction, caractérisés en ce qu'ils comportent en surface, au moins sur le coté visible, au moins un textile non-tissé de filaments continus synthétiques solidaire du support desdits éléments. The subject of the present invention is dressed prefabricated construction elements, characterized in that they comprise on the surface, at least on the visible side, at least one nonwoven fabric of synthetic continuous filaments secured to the support of said elements.

La présente demande a aussi pour objet un procédé pour la réalisation par moulage des éléments ci-dessus, caractérisé en ce que l'on associe avec le support et sur au moins une face de ce dernier au moins un non-tissé de filaments continus synthétiques puis que l'on soumet l'ensemble à une opération de formage dans une presse. The present application also relates to a process for the production by molding of the above elements, characterized in that one associates with the support and on at least one face of the latter at least one nonwoven of synthetic continuous filaments then that the assembly is subjected to a forming operation in a press.

La présente demande concerne un procédé pour la réalisation par injection des éléments ci-dessus décrits, caractérisé en ce que l'on injecte dans un moule froid une matière plastique, éventuellement chargée, ledit moule étant recouvert sur au moins une de ses faces internes d'au moins un textile non-tissé de filatents continus synthétiques. The present application relates to a method for producing by injection of the elements described above, characterized in that a plastic material, possibly loaded, is injected into a cold mold, said mold being covered on at least one of its internal faces. '' at least one nonwoven textile of synthetic continuous filatents.

Pour le moulage, les matières premières des supports sont de type connu, telles que carton ondulé, déchets de fibres textiles ou de fibre de verre, de fibres cellulosiques, enrobées de résines thermoformables, mousse rigide, pitre, ciment, matières plastiques chargées éventuellement de produits tels que talc, etc
Le non-tissé de filaments continus synthétiques utilisé est de préférence aiguilleté sur au moins une face d'un nombre de perforations supérieur à 50 perforations au centimètre carré.For molding, the raw materials of the supports are of known type, such as corrugated cardboard, waste of textile fibers or glass fiber, of cellulose fibers, coated with thermoformable resins, rigid foam, pitre, cement, plastics possibly loaded with products such as talc, etc.
The synthetic continuous filament nonwoven used is preferably needled on at least one face with a number of perforations greater than 50 perforations per square centimeter.

Ce non-tissé peut etre de couleur écrue, teint, coloré dans la masse, il peut etre imprimé au cadre, aux rouleaux, ou par transfert thermique. Le non-tissé est de préférence flambé sur au moins une face pour améliorer sa résistance au frottement. On utilise un non-tissé de poids compris entre 50 et 300 g/m2 de préférence entre 90 et 200 g/m2. Ces non-tissés sont obtenus par extrusion selon les procédés connus, de masses fondues de polymères synthétiques tels que ceux à base de polyamide1 polyester, polyoléfine, utilisés seuls, en mélange ou donnant lieu, lors de leur extrusion, à des produits bicomposites ou mixtes, on utilise de préférence un non-tissé à base de polyester tel que le polytéréphta late d'éthylène glycol extrudé seul ou en ne.. temps que du poly téréphtalate de butylène glycol pour donner des fils continus sixtes
Lc moulage peut être effectué à chaud à une t c a p é r a t u r e comprise e n t r e 100 et 2200C et à une p r c s s i o n comprise entre 0,5 et 100 bars/cm2 ou à froid avec une colle appropriée sur le support déjà formé par assemblage à l'aide d'un moule en deux parties en utilisant une pression comprise entre 0,5 et 100 bars.Lors du moulage, le non-tissé peut être utilisé seul ou avec un intercallaire qui peut être par exemple un fila plastique thermocollant par exemple en polyoléfinc, il est aussi possible d'associer le non-tissé et une matière plastique k structure alvéolaire puis d'utiliser l'intercallaire. L'intercallaire peut aussi être une poutre thermocollante. Lors de l'injection, le support injecté est en général k base de résine
ABS ou de polyoléfines chargées. L'injection et le soulage sont effectués selon les procédés connus et sur du matériel connu.This nonwoven can be of ecru color, dyed, colored in the mass, it can be printed with the frame, with the rollers, or by thermal transfer. The nonwoven is preferably flamed on at least one side to improve its resistance to friction. A nonwoven of weight between 50 and 300 g / m2 is used, preferably between 90 and 200 g / m2. These nonwovens are obtained by extrusion according to known methods, from melts of synthetic polymers such as those based on polyamide1 polyester, polyolefin, used alone, as a mixture or giving rise, during their extrusion, to bicomposite or mixed products , preferably a polyester-based nonwoven such as polyethylene terephta late extruded alone or in combination with poly butylene terephthalate glycol is used to give continuous six-ply yarns.
The molding can be carried out hot at a temperature between 100 and 2200C and at a pressure between 0.5 and 100 bars / cm2 or cold with an appropriate glue on the support already formed by assembly using '' a two-part mold using a pressure of between 0.5 and 100 bars. it is also possible to combine the nonwoven and a plastic material with a cellular structure and then use the interlayer. The interlayer can also be a fusible beam. During the injection, the injected support is generally k resin base
ABS or loaded polyolefins. The injection and the relief are carried out according to known methods and on known equipment.

Pour le forcage-moulage, on utilise des températures et pressions compatibles avec la matière première du textile non-tissé et les supports utilisés, par exemple lorsqu'on utilise un non-tissé teint ou imprimé, la température ne doit pas provoquer de dégra- dation du colon recherché.For forcing-molding, temperatures and pressures compatible with the raw material of the nonwoven fabric and the supports used are used, for example when a dyed or printed nonwoven is used, the temperature must not cause degradation. donation of the colonist sought.

Les non-tissés de filaments continus obtenus par voie fondue, contrairement aux non-tissés obtenus par voie sèche ou humide présentent une isotropie, une bonne déformabilité dans les zones très sollicitées, il n'y a pas d'amincissement dans les zones de forte déformation car la cohésion de ces nontissés de filaments continus permet une sollicitation de la matière sur une plus grande suface, il ne se produit pas de plis au moulage, pas d'éclatement sur les parties en relief le non-tissé est opaque, il présente une bonne résistance à l'abrasion, à la lumière, au vieillissement, une bonne tenue thermique, une solidité au nettoyage ; on obtient ainsi en une seule opération un complexe support/textile en une seule pièce ce qui est important du point de vue économique. Indépendemment de l'utilisation de non-tissés à surface plane, il est possible d'utiliser des non-tissés gaufrés entre cylindres métalliques gravés et chauffés par exemple pour le polytéréphtalate d'éthylène glycol à une température de 220/2300C. Avec ces éléments, on peut ainsi réaliser par exemple tout habillage intérieur de tout moyen de transport tel que pavillons, panneaux de portières, arrières de sièges, tableaux de bord, il est aussi possible d'obtenir en ameublement un mobilier plastique à surface textile en une seule opération, dans le batiment des cloisons d1apparte- ments avec revêtement textile incorporé lors de la réalisation des cloisons préfabriquées, l'habillage intérieur et en extérieur d'électroménager tel que machine à laver, réfrigérateur. The nonwovens of continuous filaments obtained by the melt process, unlike the nonwovens obtained by the dry or wet route exhibit isotropy, good deformability in the highly stressed areas, there is no thinning in the areas of strong deformation because the cohesion of these nonwovens of continuous filaments allows a solicitation of the material on a larger surface, there are no folds in the molding, no bursting on the raised parts the nonwoven is opaque, it has good resistance to abrasion, to light, to aging, good thermal resistance, fastness to cleaning; in this way a support / textile complex is obtained in a single piece, which is important from an economic point of view. Regardless of the use of nonwovens with a flat surface, it is possible to use embossed nonwovens between etched and heated metal cylinders for example for polyethylene terephthalate glycol at a temperature of 220 / 2300C. With these elements, it is thus possible, for example, to produce any interior covering for any means of transport such as pavilions, door panels, rear seats, dashboards, it is also possible to obtain plastic furniture with textile surface in furniture. a single operation, in the building of apartment partitions with textile covering incorporated during the production of the prefabricated partitions, the interior and exterior cladding of household appliances such as washing machine, refrigerator.

Les exemples suivants illustrent la présente demande sans la limiter. The following examples illustrate the present application without limiting it.

Exemple 1-
Pour la réalisation de pavillons pour véhicules automobiles, on utilise d'une part, un non-tissé de filaments continus en polytéréphtalate d'éthylène glycol, de couleur bleue, aiguilleté à 170 coups au centimètre carré, de poids 110 g/m2, de titre au brin 3,5 dtex, de marque déposée Bidim de la Société RHoNE-POULÈNC-
TEXTILE, flambé sur les tex faces sur une rampe à gaz à la -vi- tesse de 100 m/min, et d'autre part, un panneau plan aggloméré de résine polypropylène et de sciure de bois de marque WOODSTOOK de la Société GRIFFINE MARECBAL, d'épaisseur 2 millimètres, de poids 1,8 kg/m2 . On pose le panneau sur une des deux parties d'un moule chauffé à 160 C, on maintient à cette température pendant 2 minutes, puis on recouvre du non-tissé et on abaisse l'autre partie da moule en pressant par palier, pression utilisée 5 bars/cm2 On obtiens ainsl,de façon économique,en une seule opération, un complexe support non-tissé présentant un excellent aspect textile sur la face visible du pavillon sans pli, ni défaut.Example 1-
For the production of pavilions for motor vehicles, on the one hand, a nonwoven of continuous filaments of polyethylene terephthalate, blue in color, needled at 170 strokes per square centimeter, weighing 110 g / m2, title to the strand 3,5 dtex, of Bidim registered trademark of the Company RHoNE-POULÈNC-
TEXTILE, flamed on the tex faces on a gas ramp at a speed of 100 m / min, and on the other hand, a flat panel made of polypropylene resin and sawdust brand WOODSTOOK from the company GRIFFINE MARECBAL , thickness 2 millimeters, weight 1.8 kg / m2. The panel is placed on one of the two parts of a mold heated to 160 C, maintained at this temperature for 2 minutes, then covered with non-woven fabric and the other part of the mold is lowered by pressing stepwise, pressure used 5 bars / cm2 We thus obtain, economically, in a single operation, a non-woven support complex having an excellent textile appearance on the visible face of the pavilion without folds or defects.
