Description

RVETZMENT DE SOL OU DE MUR TUFTE DOUBLE SUR SUPPORT PAR TEBRMOCOLLAGE
La présente invention concerne un revêtement de sol ou de mur tufté doublé sur un support par thermocollage.DOUBLE TUFTED FLOOR OR WALL COVERING ON TEXTURED SUPPORT
The present invention relates to a tufted floor or wall covering lined on a support by heat sealing.

On connaît déjà de nombreux revêtements de sol ou de mur dont l'élément décoratif est constitué par des e élé- ments textiles à base de fibres, tissus ou non-tisses. La fixation de ces éléments décoratifs sur les murs et parois est le plus souvent assurée par l'intermédiaire d'une feuille, généralement en papier, que l'on peut appliquer à la manière d'un papier peint classique. Numerous floor or wall coverings are already known, the decorative element of which is made up of textile elements based on fibers, fabrics or non-wovens. The fixing of these decorative elements on the walls and walls is most often ensured by means of a sheet, generally made of paper, which can be applied in the manner of a conventional wallpaper.

La fixation de ces éléments décoratifs sur la feuille de papier est généralement effectues par collage au moyen d'adhésifs .  The fixing of these decorative elements on the sheet of paper is generally carried out by gluing by means of adhesives.

Le brevet français 2 262 725 décrit par ailleurs un revêtement mural constitué d'une nappe aiguilletée de fibres thermofusibles dans lequel une partie de ces fibres assure la liaison entre ladite nappe et le support papier la fabrication de revêtements de ce type pose pourtant de nombreux problèmes en raison de la nécessité impérieuse de limiter la fusion des fibres à une épaisseur très faible par rapport à leépaisseur totale de la nappe pour maintenir la souplesse du produit fini. French patent 2,262,725 also describes a wall covering consisting of a needled sheet of hot-melt fibers in which a portion of these fibers provides the connection between said sheet and the paper support. The production of coverings of this type nevertheless poses numerous problems. because of the imperative to limit the melting of the fibers to a very small thickness compared to the total thickness of the sheet to maintain the flexibility of the finished product.

La présente invention 'est donnée pour objet de remédier à cet inconvénient tout en élargissant le domaine d'application des revêtements de ce type, en proposant un revêtement de sol ou de mur du type constitué par un élé- ment décoratif, compose au moins partiellement de fibres thermofusibles, et associé par thermocollage à une feuille support permettant 50D application ultérieure sur les murs et parois ou sa pose sur le sol, et dont l'originalité consiste en ce que les éléments décoratifs sont constitués par des groupes de fils dont au moins une partie est susceptible de fondre à des températures situées entre 140 et 1750C, tuftés sur un support textile relativement insensible à ces températùres, et entre que la base des tufts est rendue simultanément solidaire, par thermocollage, du support de tuftage et de la feuille destinée à permettre son application ultérieure sur les murs et parois, ou sa pose sur le sol. The object of the present invention is to remedy this drawback while widening the field of application of coatings of this type, by proposing a floor or wall covering of the type constituted by a decorative element, composed at least partially of hot-melt fibers, and associated by heat-bonding to a support sheet allowing 50D subsequent application to walls and walls or its laying on the floor, and whose originality consists in that the decorative elements consist of groups of wires of which at least a part is capable of melting at temperatures between 140 and 1750 ° C., tufted on a textile support relatively insensitive to these temperatures, and between that the base of the tufts is made simultaneously integral, by heat-bonding, with the tufting support and the sheet intended to allow its subsequent application on walls and walls, or its installation on the floor.

Les fils de tuftage sont de préférence des fils de po lypropplène susceptibles de fondre entre 150 et 1650C,
Selon un mode de réalisation de l'invention, le support de tuftage est un non-tissé en polyester.The tufting yarns are preferably yarns of lypropplene capable of melting between 150 and 1650C,
According to one embodiment of the invention, the tufting support is a polyester nonwoven.

Alternativement, le support de tuftage est un nontissé en fibres bi-composantes polyester enrobe de polyamide 6. Alternatively, the tufting support is a nonwoven of two-component polyester fibers coated with polyamide 6.

Dans les deux cas précédents, la feuille destinée à permettre l'application du revêtement est un papier tenture classique d'un poids au m2 de 70 à 110 g et de préférence de 90 g/m2. In the two preceding cases, the sheet intended to allow the application of the coating is a standard wall paper with a weight per m2 of 70 to 110 g and preferably of 90 g / m2.

Le support de tuftage peut également être en polypro pyrène.  The tufting support can also be made of polypro pyrene.

Dans ce cas, la feuille destinée à permettre l'application ultérieure du revêtement est de préférence un papier crêpe. In this case, the sheet intended to allow the subsequent application of the coating is preferably crepe paper.

Selon un autre mode de realisation, la feuille destinée à permettre l'application ou la pose du revêtement est un non-tissé polyester d'un poids au m2 de 25 à 120 g et de préférence de 60 à 80 g. According to another embodiment, the sheet intended to allow the application or the laying of the coating is a polyester nonwoven with a weight per m2 of 25 to 120 g and preferably from 60 to 80 g.

Alternativement, la feuille destinée à permettre l'application ou la pose du revêtement est un tissu clos et résistant en fibres naturelles ou synthétiques dont le point de fusion est égal ou supérieur a 1900C.  Alternatively, the sheet intended to allow the application or the laying of the coating is a closed and resistant fabric made of natural or synthetic fibers whose melting point is equal to or greater than 1900C.

La présente invention sera mieux comprise d'ailleurs et ses avantages ressortiront bien de la description qui suit, d'un mode de realisation du revêtement selon l'invention, en référence au dessin schématique annexé dans lequel
Figure 1 est une vue en coupe du revêtement
Figure 2 est une vue en plan de dessous du revêtement avant doublage sur feuille support
Figure 3 est une vue similaire à figure 2, après doublage sur feuille support, la feuille étant partiellement arraches
Figure -4 est une vue très schématique de l'appareillage servant à l'obtention du revêtement selon l'invention
Sur les figures (2) désigne de façon générale le revêtement selon l'invention, (3) les groupes de fils formant les tufts, (4) le support de tuftage et (5) la
feuille support destinée à permettre l'application ultérieure du revêtement (2) sur les murs ou parois, ou sa pose au sol.The present invention will be better understood moreover and its advantages will emerge clearly from the description which follows, of an embodiment of the coating according to the invention, with reference to the appended schematic drawing in which
Figure 1 is a sectional view of the coating
Figure 2 is a bottom plan view of the coating before doubling on support sheet
Figure 3 is a view similar to Figure 2, after doubling on support sheet, the sheet being partially cut away
Figure -4 is a very schematic view of the apparatus used to obtain the coating according to the invention
In the figures (2) generally designates the coating according to the invention, (3) the groups of threads forming the tufts, (4) the tufting support and (5) the
support sheet intended to allow the subsequent application of the coating (2) on the walls or walls, or its laying on the ground.

Selon l'invention, et comme on le voit aux figures 1 et 3, la base des tufts (3) est solidaire à la fois du support de tuftage (4) et de la feuille support (5). According to the invention, and as seen in Figures 1 and 3, the base of the tufts (3) is integral with both the tufting support (4) and the support sheet (5).

Les tufts (3) sont constitués par des fils texturés de polypropylène plus généralement connus sous l'appela tionanglosaxonne de l'Bulked Continuous Filaments" (B.C.F.). The tuff (3) consist of textured polypropylene threads more generally known under the name Anglo-Saxon of the Bulked Continuous Filaments "(B.C.F.).

Le titre de ces fils varie, bien entendu, selon la jauge de la machine à tufter et la couverture et le moelleux souhaité pour le velours. Pour une machine à tufter de jauge 1/8, et un poids au m2 de fils déposés de 300 g, on utilise, par exemple, des BCF polypropylène de 2000 dtex pour un serrage de 31 points et une hauteur de velours de 4 mm. The title of these threads varies, of course, depending on the gauge of the tufting machine and the coverage and softness desired for the pile. For a tufting machine of 1/8 gauge, and a weight per m2 of yarn deposited of 300 g, we use, for example, BCF polypropylene of 2000 dtex for a tightening of 31 points and a pile height of 4 mm.

Pour une machine à tufter de jauge 5/32, et un poids au m2 de fil déposé de 400 g, on utilise, par exemple, des BCF polypropylène de 2900 dtex pour un serrage de 34 points et une hauteur de velours de 6 mm. Alternativement, il peut s'agir de fils filés traditionnels, de numéro métrique 3,8 par exemple réalisé en technique semi-peignée et comportant un minimum de 50 ,' de fibres de polypropy lène, ce pourcentage pouvant atteindre 100 ,'. L'éventuel autre composant (qui n'intervient pas dans le processus de fixation selon l'invention) est choisi en fonction d'exigences diverses demandées au revêtement fini, telles que la résistance à l'usure et au frottement, ou bien en fonction d'exigences de prix.Le titre des fibres variera bien entendu selon le toucher et l'aspect désiré et pourra se situer entre 3,3 et 17 dtex. Par exemple, pour une
jauge de 1/8 et un poids au m2 de fil déposé de 350 g, on a utilisé un fil de numéro métrique 3,8 (2630 dtex) comportant 50 % de fibres de polypropylène 17 dtex et 50 ,' de fibres de polyamide écru 6,7 dtex pour un serrage de 30 points et une hauteur de velours de 4 mm.For a tufting machine of 5/32 gauge, and a weight per m2 of deposited yarn of 400 g, we use, for example, BCF polypropylene of 2900 dtex for a tightening of 34 points and a pile height of 6 mm. Alternatively, it may be traditional spun yarns, with metric number 3.8 for example produced in semi-combed technique and comprising a minimum of 50% of polypropylene lene fibers, this percentage being able to reach 100%. The other possible component (which does not intervene in the fixing process according to the invention) is chosen according to various requirements demanded from the finished coating, such as resistance to wear and friction, or else depending price requirements. The titer of the fibers will of course vary according to the touch and the desired appearance and may be between 3.3 and 17 dtex. For example, for a
1/8 gauge and a weight per m2 of deposited wire of 350 g, we used a wire of metric number 3.8 (2630 dtex) comprising 50% polypropylene fibers 17 dtex and 50, unbleached polyamide fibers 6.7 dtex for a tightening of 30 points and a pile height of 4 mm.

Le choix du support de tuftage (4) est également très important puisque d'éventuels retraits ou déformations à chaud de ce support lors de ltopération de thermocollage seraient susceptibles d'entraîner des perturbations dans le compOrtement de la feuille support (5) destinée à permettre l'application ultérieure ou la pose du revêtement (2). Qu'il s'agisse d'un support tissé ou non-tisse, il est essentiel que ce support soit le moins sensible possible aux températures de thermocollage ultérieurement appliquées. The choice of the tufting support (4) is also very important since any shrinkage or hot deformation of this support during the heat-sealing operation would be likely to cause disturbances in the behavior of the support sheet (5) intended to allow subsequent application or laying of the covering (2). Whether it is a woven or non-woven support, it is essential that this support is as sensitive as possible to the heat-bonding temperatures subsequently applied.

C'est ainsi que, pour la réalisation d'un article tufté velours coupé, on a utilisé un non-tissé du type dit wlié à la filature" de 70 g/m2 (ce qui permet d'obtenir un aspect régulier pour un poids au m2 relativement faible). Thus, for the production of a tufted cut velvet article, a nonwoven of the so-called wlié type "70 g / m2" was used (which makes it possible to obtain a regular appearance for a weight relatively small m2).

Les fibres constituant ce non-tissé sont des fibres de polyester ; elles pourraient également être choisies parmi les fibres bi-composantes, du type ame polyester/gaine polyamide.The fibers constituting this nonwoven are polyester fibers; they could also be chosen from two-component fibers, of the polyester core / polyamide sheath type.

La réalisation de ce non-tissé (ou d'article tissé) à l'aide de fibres de polypropylène est également possible mais il faudra alors apporter un soin tout particulier à la surveillance des températures de thermocollage ainsi qu'au choix de la feuille support. The realization of this nonwoven (or woven article) using polypropylene fibers is also possible but it will then be necessary to take a very particular care in the monitoring of the fusing temperatures as well as in the choice of the support sheet. .

Cette feuille support (5) assure deux fonctions intéressantes
- dans le cas d'un revêtement mural, elle facilite d'une part la mise en place et le collage du revêtement (2) sur le mur et autorise l'emploi de colles traditionnelles selon des procédés classiques, de
- d'autre, part, cette feuille joue un rôle/barrière et empêche le passage de l'air chargé de poussières et/ou de fumées arrivant des fissures présentes dans les murs à travers le revêtement (2). This support sheet (5) performs two interesting functions
- in the case of a wall covering, it facilitates on the one hand the installation and bonding of the covering (2) on the wall and allows the use of traditional adhesives according to conventional methods,
- on the other hand, this sheet plays a role / barrier and prevents the passage of air charged with dust and / or fumes arriving from the cracks present in the walls through the coating (2).

La feuille (5) est alors choisie parmi les papiers tentures classiques de 70 à 110 g/m2 et de préférence de 90 g/m2. On peut également utiliser du papier crêpé, blanc ou kraft, dont le poids au m2 (toujours supérieur au poids au m2 du papier tenture lisse le mieux adapté) sera bien sûr fonction du poids au m2 du papier d'origine ainsi que de l'intensité du crêpage. The sheet (5) is then chosen from conventional drapery papers of 70 to 110 g / m2 and preferably of 90 g / m2. We can also use crepe paper, white or kraft, whose weight per m2 (always greater than the weight per m2 of the most suitable smooth wall paper) will of course depend on the weight per m2 of the original paper as well as the intensity of creping.

Dans le cas de revêtement de sol, spécialement adapté pour des poses éphémères,(tels que les tapis de stand de foire), la feuille support (5) est choisie parmi les non-tissés polyester de 25 à 120 g/m2 et de préférence de 60 à 80 g/m2, ou parmi tout tissu clos et résistant, en fibres naturelles et/ou synthétiques pourvue que la tem pérature de fusion de ces dernières soit égale ou supérieure à 1900C. In the case of floor covering, specially adapted for ephemeral poses, (such as fair stand carpets), the support sheet (5) is chosen from polyester nonwovens from 25 to 120 g / m2 and preferably from 60 to 80 g / m2, or from any closed and resistant fabric, made of natural and / or synthetic fibers provided that the melting temperature of the latter is equal to or greater than 1900C.

'Le procédé d'obtention du revêtement selon l'invention consiste à provoquer la fusion de la base des tufts (3) implantés sur le support de tuftage (4) et à appliquer simultanément, sous pression, la feuille (5) contre ladite base des tufts. '' The process for obtaining the coating according to the invention consists in causing the base of the tufts (3) implanted on the tufting support (4) to melt and in simultaneously applying, under pressure, the sheet (5) against said base. tuff.

L'appareillage servant à l'obtention du revêtement selon l'invention est très schématiquement représenté à la figure 4. I1 se compose essentiellement d'une calandre à deux rouleaux, l'un chauffé (8), l'autre froid (7) et d'un poste de déroulage (9) de la feuille (5). The apparatus used to obtain the coating according to the invention is very schematically represented in FIG. 4. It essentially consists of a calender with two rollers, one heated (8), the other cold (7) and an unwinding station (9) for the sheet (5).

L'ensemble constitué des fils (3) tuftés sur le support (4) tel que représenté à la figure 3 et désigné par (6) arrive sur la calandre de telle sorte que la face velours du produit tufté (6) soit au contact du rouleau froid (7); l'oevers dn produit tufté (où se trouve la base des tuftés) vient se plaquer contre la feuille (5) sur la surface du rouleau chauffé (8). Sous l'action de la température et de la pression, les bases des touffes de fils (3) se ramollissent et fluent partiellement assurant de ce fait simultanément leur solidarisation sur le support de tuftage (4) et le collage sur la feuille support (5).  The assembly consisting of threads (3) tufted on the support (4) as shown in FIG. 3 and designated by (6) arrives on the calender so that the velvet face of the tufted product (6) is in contact with the cold roller (7); the invert of a tufted product (where the base of the tufted material is located) is pressed against the sheet (5) on the surface of the heated roller (8). Under the action of temperature and pressure, the bases of the tufts of threads (3) soften and partially flow, thereby simultaneously securing them to the tufting support (4) and bonding to the support sheet (5 ).

Cette solidarisation de la bas des touffes au support de tuftage (4) se substitue done au traitement classique de consolidation par enduction d'envers. La chaleur effective appliquée sur l'envers du matériau doit être suffisante (150 à 165 C) pour souder les unes aux autres à leur base les fibres des touffes et assurer leur accrochage définitif tant sur le support de tuftage (4) que sur la feuille (5) sans pour autant exercer d'action néfaste sur ledit support de tuftage (4) : retrait ou déformation. This joining of the bottom of the tufts to the tufting support (4) therefore replaces the conventional treatment of consolidation by coating upside down. The effective heat applied to the back of the material must be sufficient (150 to 165 C) to weld the fibers of the tufts to each other at their base and ensure their permanent attachment both on the tufting support (4) and on the sheet. (5) without exerting a harmful action on said tufting support (4): shrinkage or deformation.

Le choix d'un support non-tissé en fibres de polyester (températures de ramollissement de 220/2400C, température de fusion 255/2650C), est spécialement indiqué. Dans le cas d'utilisation de ce type de support, tout papier tenture classique peut être utilise' pour l'application murale. The choice of a non-woven support in polyester fibers (softening temperatures of 220 / 2400C, melting temperature 255 / 2650C) is specially indicated. When using this type of support, any conventional wall paper can be used for wall application.

On peut également envisager d'utiliser un support de tuftage en polypropylène tissé ou non-tissé. Il est bien sûr nécessaire dans ce cas d'apporter une attention toute particulière aux conditions de températures du rouleau chauf fé (8) et au choix du papier de doublage (5) qui sera choisi alors parmi les papiers crêpés.One can also consider using a woven or nonwoven polypropylene tufting support. It is of course necessary in this case to pay special attention to the temperature conditions of the heated roller (8) and to the choice of liner paper (5) which will then be chosen from crepe papers.

I1 est bien évident par ailleurs que la température réelle du rouleau chauffé (ô) qui peut atteindre 2400C est toujours nettement supérieure à la température requise pour la fusion des bases des tufts (3) de fils de polypropylène (150 à 1650C) en raison notamment des pa ramètres de la machine tels que la vitesse de passage du revêtement, la pression effective entre les rouleaux, le secteur d'enveloppement du rouleau chauffé et le poids au m2 de la feuille support (5).  It is also quite obvious that the actual temperature of the heated roller (ô) which can reach 2400C is always significantly higher than the temperature required for melting the bases of the tuff (3) of polypropylene threads (150 to 1650C) due in particular to machine parameters such as the speed at which the coating passes, the effective pressure between the rollers, the wrapping sector of the heated roller and the weight per m2 of the support sheet (5).
