Definitions

  • the present invention relates to a transfer sheet for a leather finishing process.
  • a transfer sheet according to the invention for finishing leather in the form of skin or in the form of a ready-to-use piece for making shoes, leather goods or the like, comprising a support provided with layers superimposed of priming and / or finishing products, as well as a separate adhesive layer or incorporated into one of the priming and / or finishing products suitable for being reactivated when hot and having dielectric losses is characterized in that the material of the layer in contact with the support and intended to form the surface finishing is chosen from products of the plasticized nitrocellulose or single-component polyurethane type dissolved in solvents suitable for its attachment to said support, in that said first layer is coated with a second layer ensuring the solidity of the finish and the color, the material of which is chosen from aqueous dispersions of aliphatic polyurethane and acrylic colopymers es or one-component polyurethanes of aromatic type in organic solution and in that in said second layer is incorporated a thermoplastic adhesive of the polyurethane / vinyl acetate copolymer
  • the first layer, in contact with the silicone paper, and which is intended to provide the finishing of the skin or the piece of leather can be tinted or transparent.
  • the dyes used are those used in the leather industry, for example little organic and mineral pigments, in a modified nitrocellulosic binder.
  • Such an arrangement is particularly preferred when it is desired to give the skin or the piece of leather a coloration in two tones or two colors, for example for producing patterns giving the skin or the pieces of leather the appearance snake scales, or the like.
  • the transfer sheet Given the nature of the constituents of the transfer sheet, it can be easily manufactured on an automatic machine by a continuous process according to which said constituents are arranged in successive layers on the base support.
  • the manufacturing process as defined above provides a constant, uniform film thickness, allowing the leather to retain its natural suppleness and also providing a significant saving in finishing and / or finishing products.
  • the transfer sheet thus produced is first pre-bonded to the leather by a thermal application process carried out either using a heating press or a rotary press. continuous tightening and this to easily separate the silicone paper from the finishing layer, this pre-bonding being carried out either on whole skins, or on pre-cut pieces according to the leather pieces that one wishes to use for the manufacture of shoes, leather goods, or the like.
  • the skin or piece of leather is then subjected to a final operation in a high-frequency machine, as described in the aforementioned French patent for obtaining a particular grain on said skin or pieces or part of a piece.
  • a transfer sheet according to the invention is prepared from a support constituted by a silicone paper of the type of that sold under the name PU 2000 by the company ARJOMARI.
  • a second layer is added to it to ensure the solidity of the finish and, if necessary, the color of the leather.
  • This second base layer is added by spraying with a thickness of 0.01 mm.
  • Said second layer is then coated with a third layer of adhesive, suitable for being reactivated at around 100 ° C. and intended to ensure the adhesion of the entire film formed by the three layers on the crust or leather grain. which we want to finish.
  • a silicone paper of the type of those sold by the company ARJOMARI under the name PU 2000 is first coated with a first layer as described in Example 1 which, after drying, is provided with a second layer in which a thermoplastic adhesive is incorporated in the form of a polyurethane / vinyl acetate co-polymer.
  • a transfer sheet according to Example 1 For the finishing of a piece or skin of chrome tanned leather, using a transfer sheet according to Example 1, said transfer sheet is pre-glued in a thermal press and then, after introduction of the assembly into a silicone or resin mold suitable for high-frequency treatment, the graining is carried out in an HF machine, with an appropriate generator.
