Abstract (en)
[origin: EP1795634A1] This Invention provides a kind of leather yarn and its process of production, wherein the yarn is made of 1~100%WT of leather fiber, being mechanically opened from leather, and 0~99%WT of textile fiber. Leather fiber and textile fiber are disposed longitudinally, interlaced with each other and twisted together to form leather yarn. Process of making yarn of leather fiber is as follows: tanning animal pelage with conventional tanning process, then sorting, swelling, opening fiber, degumming, decoloring, edulcorating, grading, blending, clearing, carding, drawing, and spinning. This Invention can improve availability of animal pelage, broaden application field of animal pelage, and solve problems of low availability of animal pelage and reclamation and recycling of worn-out leather.
