Textiles having a protective function against abrasion and contact heat
The invention relates to a textile sheet product. According to the invention, said textile sheet product is characterized by a plurality of coating elements, which are arranged on a surface of a textile substrate layer of the sheet product in such a way that only part of the surface of the substrate layer is covered by the coating elements. The coating elements are made of a material that substantially is a mixture of a polymer material, preferably a prepolymer that can be crosslinked to form a thermoset, and a filler in the form of inorganic and/or metal particles. In a method according to the invention for producing a textile sheet product, a textile substrate layer and a coating material are provided. In order to form coating elements, a plurality of portions of the coating material are applied to a surface of the substrate layer. The portions of the coating material are arranged on the surface in such a way that the portions do not overlap, and only part of the surface of the substrate layer is covered by the coating material. Subsequently, the coating material is fixed, whereby a plurality of solid coating elements is formed on the substrate layer.
1. A method for producing a textile sheet product, the method comprising:
providing a textile substrate layer;
at least temporarily hydrophobing a first side of the textile substrate layer;
providing a coating material on the first side of the textile substrate layer, comprising a polymer material and a filler material, which contains inorganic and/or metal particles;
forming coating elements by,
applying a plurality of portions of the coating material to the surface of the substrate layer,
arranging the portions of the coating material on the surface of the substrate layer such that the portions do not overlap, and only a portion of the surface of the substrate layer is covered by the coating material; and
fixing the coating material, whereby a plurality of solid coating elements is formed on the substrate layer, wherein the proportion of coating elements on the entire surface of the substrate layer is between 30% and 70%, wherein the volume of the coating material on the textile substrate layer is 100 to 1500 g/m2,
wherein the surface of the substrate layer is embodied, by coating, such that the contact angle in air between surface and coating material is greater than 60°.
2. The method of claim 1 , wherein the substrate layer is embodied such that a viscous coating material is able to flow at least partially into a fiber structure of the substrate layer.
3. The method of claim 1 , wherein, after applying a plurality of portions of the coating material to the surface of the substrate layer, and prior to fixing the coating material, the coating material penetrates partially into a fiber structure of the textile substrate layer, so that, after fixation, a positive connection is produced between the substrate layer and the coating material.
4. The method of claim 1 , wherein the contact angle is greater than 80°.
5. The method of claim 1 , wherein the polymer material of the coating material is a prepolymer that can be crosslinked to form a thermoset, wherein the prepolymer is a hardenable epoxy resin prepolymer.
6. The method of claim 1 , wherein the plurality of portions of the coating material are applied to the surface of the substrate layer by means of screen printing.
7. The method of claim 1 , wherein the at least temporarily hydrophobing a first side of the textile substrate layer is achieved by impregnation.
