Definitions
- the invention relates to the field of the textile industry, and more particularly textile complexes associating a textile core and polymeric coating layers. It aims to manufacture materials combining good mechanical properties, in particular resistance to abrasion and flexion, combined with a durable aesthetic appearance. It finds a particular but not exclusive application in the field of leather goods.
- textiles and in particular fabrics based on high-tenacity fibers such as carbon, aramid, glass or basalt, are used for their mechanical properties of tensile strength.
- thermoplastic or thermosetting resins are generally used while being embedded in thermoplastic or thermosetting resins, or still wrapped or tensioned so that the fibers express their intrinsic properties.
- the Applicant has designed a textile complex including a woven core based on high tenacity yarns, such as, for example, carbon, aramid, basalt or glass yarns, covered on its face with a first bilayer film comprising a heat-sealing layer based on polyurethane, adhering to the textile core, and a cover layer also based on polyurethane, having a melting point higher than that of the heat-sealing layer.
- a textile complex including a woven core based on high tenacity yarns, such as, for example, carbon, aramid, basalt or glass yarns, covered on its face with a first bilayer film comprising a heat-sealing layer based on polyurethane, adhering to the textile core, and a cover layer also based on polyurethane, having a melting point higher than that of the heat-sealing layer.
- the complex On its reverse side, the complex comprises a second bilayer film comprising a heat-bonding layer in contact with the textile core, based on polyurethane including colored fillers, and an outer layer based on polyurethane, and having a melting point greater than that of the fusible layer of the second bilayer film.
- the invention consists in complexing the fabric with polyurethane layers which have good adhesion to the textile, in order to limit delamination, increase the bending strength and give a pleasant touch.
- the colored charges of the film of the reverse side confer a global opacity of the complex, and in particular at the level of the zones of opening between the woven threads.
- the multilayer film also adheres firmly to the fabric by its fraction in contact with the fibers of the reinforcement, while the outer fraction of this film provides protection of the complex against mechanical aggression and ultraviolet radiation.
- the bilayer film present on the face side is transparent, so as to reveal the woven reinforcement from the outside.
- the bilayer film of the face face has a suitable surface condition that can be grained according to a predetermined pattern, or completely smooth.
- the thickness of the film present on the face side is relatively thick, and typically has a thickness between three and five times that of the thickness of the film on the back side.
- This thickness thus makes it possible to produce sufficiently deep graining patterns, without, however, rigidifying the complex too much and thus retaining its flexibility.
- the invention also relates to a method of manufacturing this complex, which therefore includes a woven core based on high tenacity yarns.
- a bilayer film comprising a heat-sealing layer based on polyurethane, this heat-sealing layer being oriented towards the woven core of the intermediate product, as well as a covering layer;
- the fusible material of the two bilayer films is softened so that it comes into intimate contact with the reinforcement, and fills the volumes generated by the embossing son reinforcement.
- the filaments of the reinforcement threads are somehow coated with the heat-sealing material, which greatly improves the bending resistance of the reinforcement.
- the use of a compressible foam makes it possible to ensure pressure on the grained paper, so that the patterns of the paper are impinged on the bilayer film of the face-face, the unevenness of the thickness of the graining being thus collected by compression of the characteristic foam.
- the first lamination step allowing the complexing of the back side is performed on a carpet machine that has two successive sectors, namely a first heating sector, then a second cooled sector.
- these two sectors are advantageously separated by a calender ensuring pressure on the backing bilayer film, and coming to press firmly against the reinforcement, filling the volumes due to the embolization of the textile and thus ensuring optimal adhesion.
- This adhesion is particularly important at the interstices of the weaving points, to avoid the partial detachment of the film during the bending manipulations that may be involved in the routine use of the complex.
- the bilayer film can be brought into contact with the textile core via a removable support layer allowing manipulation and training inside the carpet machine.
- This support layer which can typically be paper-based or polyester-based, is then removed.
- drum calender ensures a pressure of the multilayer film on the woven core over a portion of the circumference of the heating drum, which may advantageously be greater than half the circumference of this drum.
- the pulling belt comes to face the hot drum over more than half or even three quarters of its circumference, while being kept under mechanical tension, so as to press the unwinding material on the heating drum.
- Figure 1 is a simplified sectional view of a complex according to the invention.
- Figure 2 is a simplified side view of a machine on which is performed the first lamination step of the method according to the invention.
- Figure 3 is a simplified side view of a machine illustrating the implementation of the second lamination step of the method according to the invention.
- FIG. 1 illustrates a complex according to the invention, which comprises a woven core 1, composed of warp-woven and warp 2 warp yarns which is determined according to the desired aesthetic appearance of the reinforcement.
- this core 1 may be composed of 3K carbon son.
- the complex On its face location, that is to say that which will be intended to be visible on the article made from the complex, the complex comprises a layer 5 formed of a bilayer film, which is itself formed of two elementary layers 6, 7.
- This film 5 is essentially transparent, so as to reveal the structure of the woven reinforcement 1 on the outside.
- the lower layer 6 of the bilayer film is based on thermoplastic polyurethane, with a thickness of a few tens , or at most a hundred microns.
- the lower layer 6 is heat-bondable because it has a relatively low melting point of between 90 and 140 ° C.
- the cover layer 7 of the multilayer film of the face face has a similar thickness, or even slightly greater, typically between 50 and 150 microns.
- the melting point of the material of the upper elemental layer 7 is greater than the melting point of the lower layer 6, and typically between 140 and 180 ° C, and preferably between 150 and 160 ° C.
- this bilayer film 5 may be the film marketed by the company FAITPLAST SPA, under the reference FAITE M VIX 1067 NEUTRO.
- the multilayer film of the face may have on its outer face 9 deformations 8 forming a graining, the pattern and geometry are set according to the desired aesthetic effect.
- the reverse face of the complex is covered in turn with a bilayer film 10, and also based on thermoplastic polyurethane.
- This film 10 has an elementary layer 11 in contact with the textile core 1, which is heat-bondable, and having a melting point of the order of 90 to 140 ° C, and preferably between 1 10 and 120 ° C.
- This layer includes color charges, typically black, so as to make the complex opaque.
- color charges typically black
- the color of the charges can be adapted to that of the reinforcing son.
- the charges may be white.
- This elementary layer 11 is covered by the outer layer 12 which is also made of thermoplastic polyurethane, with a melting point higher, typically between 140 and 180 ° C, and preferably close to 160 ° C.
- This outer layer may or may not include colored fillers, in order to increase the opacifying power of the layer coating the reverse side.
- this bilayer film 10 may be the film marketed by FAITPLAST under the reference FAITE ME EASY SYSTEM O8HB NERO, of a thickness of 40 microns with two elementary layers of the same thickness.
- FIG. 2 illustrates the first step of the process for manufacturing the complex according to the invention, allowing the lamination of the back film. More specifically, the woven core 1 is unwound from an inlet roll 101, and penetrates after passing on the deflection roller 102 in a carpet machine, having two mats 110, 120. These two belts are driven between the rollers 111, 112 for the upper carpet 110, and the rollers 121, 122 for the lower carpet 120.
- These two mats 110, 120 circulate between two cylinders 117, 118 located in the central part of the machine, and forming a pressurized calender. Upstream of the calender 107, the machine comprises heating means 114, 124, for heating the material flowing between the two belts 110, 120.
- cooling means Downstream of the calender 107, cooling means are provided to ensure cooling of the material having been calendered.
- a roller 103 for supplying the bilayer film 10 intended to form the reverse side.
- This bilayer film 10 is associated with a support or liner which can typically be a paper or a film of polyethylene terephthalate (PET) 108, and for manipulating the bilayer film 10 without imposing excessive traction.
- a roll 130 is provided for the recovery of the support 108. The intermediate product formed of the textile core 1 and the multilayer film back 10 is then returned to the roller 51.
- the machine 100 may be a machine marketed by MEYE.
- the heating time, corresponding to the circulation time in the first part 105 of the machine 100 is of the order of 3 minutes, while the circulation time in the cooling zone 106 is of the order of 2 minutes.
- the calendering force is of the order of 20 to 30 N / cm.
- the method implements a second lamination step performed on the machine, illustrated schematically in FIG.
- the drum calender 200 illustrated in FIG. 3 mainly comprises a heating drum 201 and a pull-down belt 202 which circulates around deflection rollers 203, 204, 205, 206 and one of the rolls 211 of the calender 210.
- rollers are arranged so that the belt 202 comes into view of the drum 201 over a large part, typically half or three quarters of the circumference of the drum 201.
- Adjusting means are provided to maintain the tension of the belt 202, and therefore the pressure applied by the belt 202 on the drum 201, and therefore on the material that will circulate between these two bodies.
- the carpet 202 is made of a particularly resistant material, and typically based on aramid yarns or the like.
- the machine At the outlet of the heating drum 201, the machine comprises a two cylinders 211, 212 forming a heating shell.
- the intermediate product 50 from the first lamination comprising the textile core 1 and the bilayer film of the reverse side 10.
- This product is introduced from so that the bilayer film of the reverse side 50 comes into contact with the heating drum 201. 11 thus has outwardly the face of the textile 1 ready to receive the contact of the bilayer film 5 of the face.
- a grain paper 220 is also introduced into the machine on the face of the center bilayer film 5 facing outwardly of the complex.
- the surface state of this paper comprises raised patterns which are in negative graining patterns that one wishes to obtain on the final complex.
- this paper has undergone on the face which comes into contact with the bilayer film 5 a particular finish, which allows easy demolding, despite exposure during the second stage of the process at high temperatures, of the order of 200 ° vs. It is indeed preferable that the material of the bilayer film does not penetrate by capillarity into the embossed paper. Satisfactory results are noted using an embossing paper of the ULTRACAST ADVA range, with a design referenced as NABUK by SAPPI.
