Definitions
- the present invention relates to a new type of complex material based on a textile structure, in particular fabric, associated with a layer of thermoplastic material such as polyolefin sheet, in particular polyethylene.
- Such articles are used in particular as coating materials, in particular in the field of furniture, for the coating of vehicle seats, the coating of the internal walls of the latter, for example dashboards, door walls, headlamps. roofs, luggage ...
- a calender comprising a cylinder coated with a layer of rubber (or the like), the other cylinder being, in turn, made of steel and its surface being grained in order to give at the article produces a surface finish which not only contributes to the aesthetic appearance, for example by imitating natural materials such as leather, but also prevents the article from being slippery and / or sticky when used as as seat or wall covering, in particular in the automotive or furniture sector.
- the textile support is associated with a film intended to constitute the surface support coating directly at the outlet of the production installation d 'such a film.
- a calender comprising a smooth steel roller and a rubberized counter roller.
- the fabric is in contact with the smooth steel roller while the film is in contact with the rubberized roller; - the film is stretched in the area between the outlet of the die and the junction line between the rollers of the calender;
- the film is at a temperature close to its temperature at the outlet of the die.
- the stretching of the film between the die and the junction line is obtained by appropriately adjusting the speed of the rollers of the calender, this stretching being carried out over a very short distance, of the order of five centimeters, the temperature of the film only lowering slightly on this path and being in particular of the order of 200 ° C at the time of superposition with the support fabric.
- the support fabric can also be preheated.
- the rubberized cylinder must be flexible on the surface in order to allow the fabric to sink in and the film to be shaped during bonding. After passing between the calender and the connection of the fabric and the film, the complex formed is cooled and then received, for example in the form of a winding.
- thermoplastic film any material other than
- PVC which can adhere under the action of heat and pressure to the support fabric.
- films based on polyurethane, polyethylene, polypropylene, cellulose acetate, etc. can be either mass-colored or transparent. When they are transparent, it is possible to use previously decorated fabrics, for example by printing, which will therefore be visible after formation of the complex.
- the method as described in FR 2 583 339 is suitable and is characterized in that the basic textile support is, in this embodiment, associated with the film intended to constitute the surface coating always directly at the outlet of the installation for producing such a film, said association being carried out by means of a calender comprising a smooth steel roller and a rubberized counter roller.
- the continuous basic textile support which can be a fabric, a nonwoven or a closed knit, is brought against the rollers of the calender while being in contact with the rubberized roller.
- a second textile structure intended to form the decoration structure constituted by an openwork textile such as a warp knitted fabric or Rachel with knitted stitches, is brought simultaneously to the level of the grille while being him in contact with the smooth cylinder.
- the film is at a temperature close to its temperature at the outlet of the die.
- the stretching of the film between the die and the junction line is obtained by appropriately adjusting the speed of the rollers of the calender, this stretching being carried out over a very short distance, of the order of five centimeters, the temperature of the film decreasing only slightly on this path compared to its temperature at the outlet of the extruder.
- the openwork textile which is intended to form the decoration is fed at a speed slightly lower than the speed of call through the cylinders of the grille.
- this speed is approximately 2 to 3% lower than the call speed of the radiator grille.
- the spacing between the cylinders of the calender is adjusted so that a pressure of the order of about five bars is exerted over the entire width of the complex.
- Openwork textile therefore gives certain relief effects to the assembly which it forms with the plastic film.
- thermoplastic material in particular based on polyethylene or polypropylene, bringing the richness of the decorations of these two materials.
- the single appended figure illustrates the way in which the process which is the subject of FR 2,583,339 is adapted to obtain a new type of complex in accordance with the invention, this figure being a schematic view, at the end, showing how the succession is carried out of the different constituents.
- the new complex according to the invention is therefore produced on an installation which comprises a conventional extrusion head (1), making it possible to form a film, for example based on a plastic composition.
- a calender designated by the general reference (3), calender consisting of two cylinders (4,5), driven in rotation at a determined speed and maintained with a slight difference l relative to each other, while maintaining pressure against the materials brought between the cylinders of this calender.
- the cylinder (4) is a smooth surface steel cylinder.
- the cylinder (5) is a cylinder coated with a layer of flexible rubber (6), itself silicone.
- the textile support (7) constituted by a fabric or knitted fabric, is brought between the cylinders (4,5) so as to be in contact with the rubberized cylinder (5).
- This second textile structure (10) is delivered by means of cylinders (11) at a speed slightly lower than the peripheral speed of the rollers of the calender (4,5), the speed difference being generally of the order from 2 to 3%.
- the distance between the outlet (8) of the extruder (1) and the pinch line (9) between the three constituents of the textile support (7), film (2) and openwork textile decoration (10), is such that the film undergoes only a slight cooling in this area.
- a distance of the order of five centimeters between this outlet is suitable and allows the film to be kept at a temperature in the region of 200 ° C at the time of joining in the case of the extrusion of a polyolefin-based film.
- additional heating means could be provided to maintain this temperature in the event that the extrusion head is further from the cylinders of the calender.
- the speed of rotation of the cylinders (4) or (5) is such that the film is stretched strongly between the exit zone (8) of the extruder and the pinch area.
- the film is based on polyolefin and has a thickness of 0.8 mm at the outlet of the die, stretching makes it possible to reduce this thickness to approximately 0.350 to 0.400 mm at the time of the superposition.
- a complex structure is produced in accordance with the invention under the following conditions:
- Base support fabric (7) consisting of a warp and weft fabric in brown color.
- This warp and weft fabric is cotton-based and has
- the surface mass of this basic textile fabric (7) is 1850 g / m
- the film (2) is a polyolefin film extruded at a speed of 4 m / min, having a thickness of 0.8 mm at the outlet of the extruder.
- This film is stretched 2 times at the outlet of the extruder and after stretching, at the time of association with the base support textile (7), weighs 350 g / m 2 '.
- This film is tinted, for example in a aluminum metal color.
- an openwork textile (10) is formed on the smooth steel cylinder (4), constituted by a warp knitting based on of polyester, consisting of threads having a count of 100 dtex and forming days of hexagonal shape, each side of which has a length of approximately 1 mm.
- This openwork fabric is delivered by two call cylinders (11) rotating at a speed slightly lower than the peripheral speed of the cylinders (4,5) and, in this case, at a speed of 3.92 m / min.
- the call speed of the complex formed (12) by the calender (4.5) is in the order of 4 m / min, thus allowing stretching of the film.
- rollers (4,5) are adjusted so as to exert a pressure of five bars over the entire width of the complex according to the nipping area.
- a complex structure is obtained comprising a basic support textile constituted by the fabric (7) covered by an aspect face. constituted by the combination of the extruded polyolefin film (2) and the openwork fabric (10) which is embedded on the surface of said film while remaining visible.
- Such a complex material can be used in particular as a seat covering, is very resistant, has an original appearance combining both the textile appearance given by the openwork fabric (10) and the colored appearance given by the extruded film (2). .
