Description

L'invention concerne un procédé de réalisation d'un tapis de sol de véhicule automobile et un tapis obtenu par un tel procédé. On connaît des complexes comprenant une couche fibreuse dont les fibres sont non fusibles en dessous d'une température T2 et une couche d'envers fusible de température de fusion Ti inférieure à T2. Ces complexes sont par exemple sous la forme de tapis de sol de véhicule automobile, la couche fibreuse étant à base de moquette ou d'aiguilleté et la couche d'envers étant par exemple à base de polyéthylène ou d'éthylène propylène diène monomère. En outre, ces complexes présentent usuellement une sous couche d'accrochage des fibres, en particulier à base de latex, permettant de conférer à la face fibreuse une grande résistance à l'abrasion. Ces complexes sont très difficilement recyclables. L'invention a pour but de proposer une voie de recyclage pour ces complexes, permettant de réaliser une couche d'envers d'un tapis de sol de véhicule automobile. L'invention a aussi pour but de s'affranchir de la sous couche d'accrochage des fibres.The invention relates to a method for producing a motor vehicle floor mat and a carpet obtained by such a method. Complexes are known comprising a fibrous layer whose fibers are non-fusible below a temperature T2 and a fusible fusible backing layer Ti less than T2. These complexes are for example in the form of motor vehicle floor mats, the fibrous layer being based carpet or needled and the backing layer being for example based on polyethylene or ethylene propylene diene monomer. In addition, these complexes usually have a sub-layer of attachment of the fibers, in particular based on latex, to give the fibrous side a high abrasion resistance. These complexes are very difficult to recycle. The object of the invention is to propose a recycling path for these complexes, making it possible to produce a backing layer of a motor vehicle floor mat. The invention also aims to overcome the underlying layer of attachment of the fibers.

A cet effet, et selon un premier aspect, l'invention propose un procédé de réalisation d'un tapis de sol de véhicule automobile, ledit procédé comprenant les étapes successives suivantes : - prévoir un complexe à recycler comprenant une couche fibreuse, dont les fibres sont non fusibles en dessous d'une température T2, et une couche fusible d'envers de température de fusion Ti inférieure à T2, - broyer ledit complexe de manière à obtenir un broyat, - réaliser à partir dudit broyat un mélange comprenant, par rapport au poids total dudit mélange, au moins 40% dudit broyat, au moins 20% de charge minérale et au moins 30% de polyoléfine, notamment sous forme de polyoléfine thermoplastique et/ou de polyéthylène, - disposer ledit mélange dans une vis d'extrusion pour l'amener à une température supérieure à Ti et inférieure à T2, afin d'obtenir une matière visqueuse chargée en fibres non fondues, - extruder ladite matière au travers d'une filière d'extrusion de manière à obtenir une couche d'envers, - en sortie de ladite filière, calandrer ladite couche d'envers directement contre une nappe de textile, ladite nappe étant dépourvue de sous couche d'accrochage des fibres, de manière à obtenir un nouveau complexe, - découper ledit complexe en flans, chacun desdits flans étant destiné à être conformé pour réaliser un tapis.For this purpose, and according to a first aspect, the invention proposes a method for producing a floor mat of a motor vehicle, said method comprising the following successive steps: - providing a complex to be recycled comprising a fibrous layer, whose fibers are non-fusible below a temperature T2, and a fusible fuselage backing layer Ti less than T2, - grinding said complex so as to obtain a ground material, - making from said ground material a mixture comprising, relative to the total weight of said mixture, at least 40% of said ground material, at least 20% of mineral filler and at least 30% of polyolefin, especially in the form of thermoplastic polyolefin and / or polyethylene, - disposing said mixture in an extrusion screw to bring it to a temperature higher than T1 and lower than T2, in order to obtain a viscous material loaded with unmelted fibers, - extruding said material through an extrusion die so as to obtain an upside-down layer, at the outlet of said die, calendering said backing layer directly against a textile ply, said ply being devoid of underlayer of adhesion of the fibers, so as to obtain a new complex - Cutting said complex blanks, each of said blanks being intended to be shaped to achieve a carpet.

Un tel procédé permet de recycler un complexe comprenant une couche fibreuse et une couche fusible, ledit complexe étant par exemple sous la forme d'un tapis usagé ou de chutes de flans servant à fabriquer un tapis.Such a method makes it possible to recycle a complex comprising a fibrous layer and a fusible layer, said complex being, for example, in the form of a used carpet or falling blanks used to manufacture a carpet.

De façon surprenante, il est observé que la couche d'envers, malgré sa composition hétérogène et en grande partie issue de produits recyclés, suffit à assurer la tenue à l'abrasion des fibres de la nappe textile, tenue qui requiert usuellement le dépôt d'une sous couche d'accrochage, opération à part entière qui entraîne un renchérissement du prix du tapis.Surprisingly, it is observed that the backing layer, despite its heterogeneous composition and largely derived from recycled products, is sufficient to ensure the abrasion resistance of the fibers of the textile web, which usually requires the deposition of dyes. a sub-layer attachment, a separate operation that leads to higher price of the carpet.

On notera en outre que la couche d'envers ainsi obtenue présente l'avantage de ne pas nécessiter d'être pourvue sur sa face d'envers d'une couche de glissement, notamment à base de non tissé, disposée en vue de faciliter le montage du tapis dans le véhicule.30 En effet, la couche d'envers obtenue par l'invention présente une surface de faible pouvoir agrippant, ce qui favorise le glissement du tapis sur la tôle de plancher de véhicule lors de son montage.It will further be noted that the backing layer thus obtained has the advantage of not having to be provided on its back side with a sliding layer, in particular a nonwoven layer, arranged in order to facilitate the In fact, the backing layer obtained by the invention has a surface of low gripping power, which promotes the sliding of the carpet on the vehicle floor plate during assembly.

Selon un deuxième aspect, l'invention propose un tapis réalisé par un tel procédé. On décrit à présent un procédé de réalisation d'un tapis de sol de véhicule automobile, ledit procédé comprenant les étapes successives suivantes : - prévoir un complexe à recycler - par exemple sous forme d'un tapis usagé ou de chutes de production - comprenant une couche fibreuse, dont les fibres sont non fusibles en dessous d'une température T2, et une couche fusible d'envers - qui peut comprendre une charge minérale telle que de la craie - de température de fusion Ti inférieure à T2, - broyer ledit complexe de manière à obtenir un broyat, - réaliser à partir dudit broyat un mélange comprenant, par rapport au poids total dudit mélange, au moins 40% dudit broyat, au moins 20% de charge minérale et au moins 30% de polyoléfine, notamment sous forme de polyoléfine thermoplastique et/ou de polyéthylène, - disposer ledit mélange dans une vis d'extrusion pour l'amener à une température supérieure à Ti et inférieure à T2, afin d'obtenir une matière visqueuse chargée en fibres non fondues, - extruder ladite matière au travers d'une filière d'extrusion de manière à obtenir une couche d'envers, - en sortie de ladite filière, calandrer ladite couche d'envers directement contre une nappe de textile - notamment sous forme de tuft ou d'aiguilleté -, ladite nappe étant dépourvue de sous couche d'accrochage des fibres, de manière à obtenir un nouveau complexe, - découper ledit complexe en flans, chacun desdits flans étant destiné à être conformé pour réaliser un tapis.According to a second aspect, the invention provides a carpet made by such a method. There is now described a method for producing a motor vehicle floor mat, said method comprising the following successive steps: providing a complex to be recycled - for example in the form of a used carpet or production falls - comprising a fibrous layer, whose fibers are non-fusible below a temperature T2, and a fusible backing layer - which may comprise a mineral filler such as chalk - with a melting point Ti of less than T2, - grinding said complex so as to obtain a ground material, - making from said ground material a mixture comprising, relative to the total weight of said mixture, at least 40% of said ground material, at least 20% of mineral filler and at least 30% of polyolefin, especially in the form of of thermoplastic polyolefin and / or polyethylene, - arranging said mixture in an extrusion screw to bring it to a temperature greater than T1 and lower than T2, in order to obtain a viscous material filled with unmelted fibers, - extruding said material through an extrusion die so as to obtain a backing layer, - at the outlet of said die, calendering said backing layer directly against a textile web - in particular in the form of tuft or needled -, said web being devoid of underlayer of attachment of the fibers, so as to obtain a new complex, - cut said complex blanks, each of said blanks being intended to be shaped to achieve a carpet.

Selon une réalisation, le procédé comprend en outre l'étape de disposer un flan dans un moule de thermoformage et de le conformer à la forme du tapis à réaliser.In one embodiment, the method further comprises the step of disposing a blank in a thermoforming mold and conforming it to the shape of the carpet to be produced.

Les fibres du complexe à recycler sont notamment à base de polyamide ou de polyester. Selon une réalisation, la couche fusible du complexe à recycler est à base de polyéthylène.The fibers of the complex to be recycled are especially based on polyamide or polyester. According to one embodiment, the fusible layer of the complex to be recycled is based on polyethylene.

Selon une autre réalisation, la couche fusible du complexe à recycler est à base d'éthylène propylène diène monomère. La couche fusible du complexe à recycler peut comprendre une dispersion de charge minérale telle que de la craie. Selon une réalisation, la filière est conformée de manière à permettre l'obtention d'une couche d'envers d'épaisseur variable.In another embodiment, the fusible layer of the complex to be recycled is based on ethylene propylene diene monomer. The fuse layer of the complex to be recycled may comprise a mineral filler dispersion such as chalk. According to one embodiment, the die is shaped so as to obtain a back layer of variable thickness.

En variante, la filière est conformée de manière à permettre l'obtention d'une couche d'envers d'épaisseur constante, une couche d'envers annexe étant appliquée par calandrage contre une partie de la largeur de ladite couche d'épaisseur constante de manière à créer une surépaisseur localisée de couche d'envers.As a variant, the die is shaped so as to allow a backing layer of constant thickness to be obtained, an additional backing layer being applied by calendering against a part of the width of said layer of constant thickness. in order to create a localized overthickness of the backing layer.

On décrit enfin un tapis de sol de véhicule automobile comprenant une nappe de textile dépourvue de sous couche d'accrochage des fibres, ladite nappe étant pourvue d'une couche d'envers - pouvant présenter une épaisseur variable - appliquée directement contre elle, ladite couche d'envers comprenant - les pourcentages étant exprimés en poids -: - une dispersion de fibres non fondues, - une dispersion d'au moins 20% de charge minérale, - et au moins 30% de polyoléfine, notamment sous forme de polyoléfine thermoplastique et/ou de polyéthylène.Finally, a floor mat of a motor vehicle comprising a textile ply devoid of an underlayer of attachment of the fibers is described, said ply being provided with a backing layer - which may have a variable thickness - applied directly against it, said layer backing comprising - the percentages being expressed by weight -: - a dispersion of unfused fibers, - a dispersion of at least 20% of mineral filler, - and at least 30% of polyolefin, especially in the form of thermoplastic polyolefin and / or polyethylene.
