Patent AT-E401441-T1: [Translated] LEATHER COLLAGEN FIBER YARN AND METHOD THEREOF
A yarn of collagen fiber of animal leather and the manufacturing process thereof, characterized in that the yarn is made of 1-100 % by weight of collagen fiber of animal leather, and 0-99 % by weight of textile fiber. The yarn of collagen fiber is made by the following steps: choosing raw materials, loosing fiber, assorting, blending, carding, drawing, and twisting; if using rawhide, the above process should also add the steps of liming, washing, de-liming, tanning and dehydrating. The raw material for making of yarn can be rawhide of any animal, as well as any leather waste material or worn-out leather. The yarn has excellent properties, including high tensile strength, abrasion resistance, softness, water adsorption, oil adsorption, flame-retardation, and can be woven, knitted and braided. The yarn can be used to weave high quality fabric with high count and high strength for the four seasons, which greatly broadens the application field of animal leather, improves the utilization of the leather, and provides a spinnable fiber for the textile industry. The present invention can be widely used in textile industry.
