  • Patent number: 8328878
    Abstract: A kind of yarn of animal collagen fiber and the manufacture process thereof, characterized in that the yarn is made of 1-100 WT % of collagen fiber of animal leather, and 0-99 WT % of textile fiber. The yarn of animal collagen fiber is made by the following procedure: choosing raw materials, loosing fiber, assorting, blending, carding, drawing, and twisting, if using the rawhide, the above procedure should add the steps of liming, washing, deliming, tanning and dehydrating. The raw material of the yarn can be the rawhide of any animal, as well as the leftover material or worn-out leather. The yarn has excellent properties, high tensile strength, abrasion resistance, softness, water adsorbent, oil adsorbent, flame-retardant, and can be woven, knitted and braided.

  • Publication number: 20120295505
    Abstract: Disclosed are a reducing leather and a method for preparing the same. The leather is mainly made by three-dimensionally interweaving the collagen fibres obtained through fibre disintegration of a leather material, with an apparent density of 0.35 g/cm3-1.4 g/cm3. The method for preparing the leather comprises the steps of preparing collagen fibres by fibre disintegration of a leather material, laying, spunlacing, and wet-hot shrinking setting. The reducing leather approaches to a natural leather in the weaving structure and the apparent density, and each of the strength criteria, as well as the wear resistance. The advantages of the leather are that the leather piece is big and regular so that it can be arbitrarily tailored, and the weaving apparent density is consistent. The scraps in the leather industry are mainly used as the raw materials for the reducing leather. The preparation method facilitates to reutilizing the resources in the leather industry.
