  • Substrate of Artificial Leather Including Ultrafine Fibers
    Publication number: 20090098785
    Abstract: Artificial leather includes a non-woven fabric made of split type conjugate fibers and a resin material for submerging or coating the non-woven fabric. The conjugate fibers are made from a first polymer with crystallization of 40% to 95% and a second polymer with crystallization of 1% to 25% by conjugate spinning. Each of the conjugate fibers is split into 24 to 128 segments.

  • Substrate of artificial leather including ultrafine fibers and methods for making the same
    Patent number: 7494697
    Abstract: There is provided a method for splitting a split type conjugate fiber. The method includes four steps. Firstly, there is provided a first polymer with crystallization of 40% to 95% and a second polymer with crystallization of 1% to 25%. Secondly, a conjugate fiber is made of the first and second polymers by conjugate spinning. Thirdly, the conjugate fiber is submerged in water so that the conjugate fiber contains water. Finally, the conjugate fiber is heated and split into fine fibers.
