  • 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.

  • Publication number: 20060046597
    Abstract: A method is disclosed for making permeable artificial leather that is realistic and permeable regarding air and liquid. At first, a non-woven cloth provided. A semi-product of the artificial leather is provided by means of immersing the non-woven cloth in a solution of a polymer resin. A highly porous sheet is provided. Finally, the final product of the artificial leather is provided by means of adhering the highly porous sheet to the semi-product of the artificial leather so that gaps exist between the highly porous sheet and the semi-product of the artificial leather.
