  • Publication number: 20070218791
    Abstract: There is disclosed artificial leather with even imprinted texture and a method for making the same. The method includes the steps of: making a thermally imprintable polyurethane resin foil into a first substrate; providing at least one polyurethane resin layer on the first substrate in a spotted manner or by rolling or spraying; making pre-determined texture or graphics on the polyurethane resin layer by imprinting; making non-woven fabric, elastic fabric, woven fabric or ultra-fine fiber materials into a second substrate; and providing the first substrate on the second substrate by adhesion so as to form the artificial leather with even imprinted texture.

  • Publication number: 20060272770
    Abstract: Disclosed is a method for making artificial leather with superficial texture. In the method, a substrate is coated, in a non-overall manner, with a wet polyurethane resin. After curing, there is provided a polyurethane resin coated on releasing paper. Thus, a semi-product is made. Texture of the releasing paper is transferred to a surface of the semi-product. Then, the semi-product with the texture on the surface is coated with a layer of a chemical. A machine is used to heat and flatten the surface of the semi-product. Finally, the semi-product is physically finished by forces so that the surface of the final product is formed with texture like that of real leather.

  • Patent number: 6592700
    Abstract: The present invention relates to a method for preparing retro-reflective sheet with high abrasion resistance produced by initially coating the first coating layer one component type polyurethane (hereinafter refer to PU) resin mixed with reflective particles on the pattern releasing paper with embossed grain, and after drying, further coating the second layer two component type PU resin adhesive agent containing colorant, then drying; above this, coating a kind of paste; finally, adhering substrate; after pre-drying and curing, divesting releasing paper, using solvent to solve the part of PU resin leaving reflective particles exposed and hardened. The material produced characterized in high abrasion resistance and using soft material as substrate. Use of the retro-reflective material produced by the invention is valuable for commercial fields like coat, vest, shoes, cap, poster, and the like.
