  • Method for producing artificial leather
    Publication number: 20070207687
    Abstract: Artificial leather includes a substrate and a coating of a first elastomeric resin provided on the substrate. The substrate contains a second elastomeric resin evenly spread in the substrate. The first elastomeric resin forming the coating is identical to the second elastomeric resin in the substrate. The substrate includes a first porous structure. The coating includes a second porous structure contiguous to the first porous structure of the substrate. Preferably, the substrate has a density larger than that of the coating.

  • Method for producing artificial leather
    Publication number: 20060147642
    Abstract: A method for producing artificial leather includes providing a substrate with an upper surface and a lower surface, providing a coating of an elastomeric resin on the upper surface of the substrate, and providing a pressure difference between the upper and lower surfaces of the substrate so as to cause infiltration of the elastomeric resin into the substrate from the upper surface to the lower surface.

  • Artificial leather
    Publication number: 20050244654
    Abstract: Artificial leather includes a substrate, a coating of a single type of elastomeric resin provided on the substrate and particles of the single type of elastomeric resin evenly spread into the substrate from the coating. The density of the substrate filled with the particles is greater than that of the coating.
