Definitions

  • the invention relates to the field of coated textiles used in various sectors, such as leather goods, furniture or interior or exterior of vehicle compartments. More specifically, it relates to a process which makes it possible to produce decorative patterns on coated textiles, with a high level of precision, as well as with patterns that may have a high resolution.
  • textile coatings used in the field of leather goods which are used in substitution or replacement of natural materials, such as leather or the like. These materials have a particularly sensitive aspect, and must therefore be of irreproachable visual quality.
  • coated textiles which are composed of a textile core covered with a top coating layer, typically based on vinyl chloride, polyurethane or thermoplastic polyolefin.
  • this textile also undergoes a treatment step that allows to give it an irregular surface condition, so as to visually reproduce the grain of the leather.
  • the customization or decoration of the textile complex requires the printing of various decorative motifs in the broad sense. It may for example be marking different identification signs, logos, or more generally various figurative or verbal motifs.
  • the coated textile receives an ink layer which passes through the pores of a membrane stretched over a frame, and which is permeable at the regions where the decorative patterns must be drawn.
  • This screen printing technique has many disadvantages when it is applied to the decoration of coated textiles with irregular surface conditions. Indeed, the screen printing operations are generally heavy, complex and expensive, insofar as they require the use of fixed frames on which the partially porous membranes are stretched. Indeed, because of the use of these frames of given dimensions, they require to perform the printing operations on textile pieces previously cut to the dimensions of the frames, these pieces are then joined together for finishing operations. Thus, the manufacturing process requires to work discontinuously, immobilizing the material to be printed during a whole printing cycle.
  • the screen printing directly applied to the textile coating layer gives results of very questionable quality, especially when the textile is exposed to subsequent graining operations or the like.
  • such an operation is generally done by the passage of the textile complex under an imprint having the inverted graining pattern, which is applied to it with conditions of temperature and pressure to be able to conform the upper coating layer of the complex.
  • this is usually done using a calender which one of the rollers has the desired graining pattern, as well as appropriate heating means.
  • this temperature and the pressure causes phenomena of modification of the colors of the markings obtained by serigraphy.
  • the object of the invention is to propose a technique that makes it possible to obtain both high resolution patterns and this with a simplified manufacturing process.
  • the invention therefore consists in manufacturing a textile complex which comprises a coating layer having localized patterns, which combines the following steps.
  • the inverted patterns are screen printed on boards of a polymer film. Then, at least on these grounds, a layer of thermo-adhesive material is deposited. At the same time, the textile complex is unwound, then these boards are applied to the coating layer of the textile complex by their printed side, as the said complex is unwound. After exposure to a source of heat and / or pressure, the units adhere to the coating layer, and then the polymer film is removed before proceeding to a graining step by application to the coating layer, d. a member having a textured surface condition such that under the effect of heat and / or pressure, the coating layer deforms to a textured surface condition complementary to that of said member. It is then possible to return the textile complex.
  • the invention consists in producing the patterns by serigraphy, not directly on the textile, but on a transfer intermediate, which requires making these patterns in an inverted orientation.
  • the positioning of these patterns on the textile complex is thus much better than for the solutions where the screen printing is done directly on the textile complex.
  • the graining operation is carried out by deforming both the coating layer and the printed patterns, by applying temperature and pressure conditions which cause the printed patterns to follow the deformation of the layer material. coating.
  • the reliefs formed by this graining are continuously covered by the printed patterns, in the areas where they are present.
  • Silk screen printing can be done on boards or panels of polymeric films that are adapted to the size of screen printing frames, which greatly facilitates printing operations.
  • the layer of thermo-adhesive material is thus deposited on the printed patterns, advantageously also by a screen printing operation. It is necessary that this layer of thermo-adhesive material covers the patterns.
  • the layer of thermo-adhesive material covers only the patterns, without overflowing, eliminating any risk of making apparent any overflow after finishing steps.
  • this adhesive layer slightly overflows patterns, in order to ensure encapsulation of the printed pattern between the polymer film and the adhesive layer, in the case where the overflows of heat-adhesive material around the patterns are invisible once the finishing is completed.
  • the polymer film may be based on different materials, and in particular based on polyester, with advantageously a translucent or even transparent state, to allow control of the printing before the transfer.
  • the adhesive material may be formulated with a base selected from the group consisting of polyesters, polyurethanes and polyamides. It can be water-based or solvent-based solutions.
  • Such a method makes it possible to produce a textile complex in the form of a roll of continuous material.
  • the coated textile is unwound in successive steps, to receive the patterns during the transfer operation. Then, the textile is then returned to form the roll comprising a series of several successive patterns. This eliminates the splicing operations that were necessary with the screen printing techniques used to date.
  • the application of the textured surface condition can be done by means of a calender, including two rollers, one of which comes into contact with the coating layer having a surface condition grained or embossed complementarily to the surface. desired surface condition for the finished product.
  • the invention allows the decoration of coated textile complexes, which uses a pattern transfer technique made by screen printing.
  • a polymer film 1 is printed by screen printing. More specifically, this polymeric film 1 is in the form of panels or boards of similar dimensions to the frame 2 of serigraphy.
  • This film 1 can typically be based on polyester, and more particularly polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • This film may also have received a surface treatment, on the face to be printed, so as to control the adhesion of the ink to be printed, and in particular to facilitate the peeling during the removal of the film 1 after hot transfer.
  • This film 1 may also have received a specific treatment on the opposite side to that intended for printing. This treatment, of the "anti blocking" type, and carried out to allow easy handling and correct stacking of film sheets 1.
  • this film 1 is transparent, which will allow, in the subsequent steps, to be able to accurately position the patterns that will be printed.
  • This film thus receives an impression through the frame 2, which supports a fabric 4 on which permeable patterns 3 have been made in a conventional manner.
  • the printing step can be performed in one or more places, depending on the colors and shapes of the patterns to be made.
  • the inks used for this printing are of acrylic type, copolymers, plastisol, or aqueous.
  • the heat-adhesive material chosen may be of the polyester type. This material is chosen to have adhesive power on the one hand on the printed inks, and on the other hand, on the coating layer of the coated textile to be decorated. This adhesive power must in particular be greater than the adhesive power of the inks on the surface treatment of the polymeric film 1, intended to facilitate the peeling of the film after transfer.
  • the deposition of the adhesive layer 8 can be carried out in different ways, and in particular by a screen printing operation, which can advantageously use the same frame as that used for the pressure of the inks. This procedure ensures a precise recovery and only printed patterns.
  • this installation makes it possible first of all to have at the level of a first station 21 the boards 31 comprising the various patterns, the printed patterns being arranged facing the upper coating layer of the coated textile 30. It should be noted that this textile complex 30 is continuous, and may be from a long roll 19.
  • the placement of the characteristic patterns with respect to the patterns already existing on the coating layer of the textile complex requires low tolerances, of the order of millimeter. In this case, we can cut the boards into small elements each having a pattern and each small element will be placed individually on the textile complex with precision compared to existing patterns.
  • the different boards 31 are deposited as the textile unwinding. It can be provided, if necessary, to interrupt the movement of the textile 30 to ensure accurate positioning of the boards 31. It is also possible that this positioning is automated and the various boards 31 are deposited continuously.
  • the coated textile 30 covered boards 31, enters a second station 22 called "transfer station".
  • the textile complex complex coated 30, printed boards 31, passes between two mats 35,36, after passing through an area including two rollers 33,34, facing one another , making it possible to apply a pressure on the two elements 30, 31 to be assembled.
  • heating means 32 are provided at the level of the circuit of the upper belt 35, so as to ensure heating of the multilayer complex 31, and in particular of the adhesive layer.
  • the temperature which prevails on the upper face of the coated textile may be a function of the chemical nature of the adhesive material covering the patterns.
  • a temperature between 110 ° C and 150 ° C makes it possible to obtain good results with adhesives based on polyester.
  • the temperature can be maintained at much lower levels, for example at room temperature, at the lower carpet circuit 36.
  • the complex complex textile coated 30 and printed boards 31 passes between two rollers 41,42 of a shell 24, to apply a pressure favoring hot contact intimate between the adhesive layer and the upper face of the coating layer of the coated textile.
  • This pressure can typically be of the order of a few Newtons to a few tens of Newtons per square centimeter.
  • the air gap between the belts 35 and 36 at the calender 24, can be set very slightly lower than the thickness of the coated textile, it being understood that the latter is much greater than the thickness of the boards 31.
  • the installation After the passage between the rollers 41 and 42 calendering, the installation comprises a cooling zone 25, at which the temperature is maintained at a low level, typically at room temperature, below, but also above the coated textile .
  • This cooling is carried out under stress, that is to say that a pressure is maintained between the two mats 35, 36, so that the adhesive layer, but also the ink layers and the coating layer coated textile, cool by staying in contact with one another, and this to avoid the creation of delamination areas, or the appearance of bubbles.
  • the machine 20 comprises a peeling station 26, at which the polymeric film 1 is eliminated, by manual or automated means. Subsequently, various treatments can be envisaged, and in particular at a station 27, the deposition of a layer of varnish to ensure in particular protection against mechanical and / or external chemical attack, and ensure also the setting to the desired shine.
  • the coated textile then undergoes, as illustrated in FIG. figure 4 , a graining operation or hot embossing.
  • the textile passes between two rollers 48,49, and its coated surface is brought into contact with a roller 48 having a surface state complementary to the desired surface finish for the finished product.
  • Complementary finishes are also possible before and / or after the hot embossing operation. It is thus possible to carry out a complementary printing, preferably before the embossing, and the deposition of the varnish layer.
  • the method according to the invention has the advantage of allowing a marking which has an excellent quality of finish, and this with a method for obtaining long lengths of continuous textile, despite the fact that the screen printing operation is performed discontinuously.
