Abstract

The invention discloses a yarn and a preparing method, and belongs to the technical field of textile manufacturing. According to the preparing method, viscose staple fibers serve as raw materials, andviscose staple fiber card slivers are obtained through opening and carding into slivers; then two or more viscose staple fiber card slivers are subjected to primary drawing and secondary drawing, andthen rotor spinning or vortex spinning or ring spinning is conducted to prepare the yarn. According to the indexes of the finished yarn product, the hairness index is 2.0-4.0, the pilling resistancereaches the level 2.5-4, the breaking strength variation coefficient is 5.8-12%, the dry breaking strength is 10.7-16 CN / tex, the dry elongation at break is 6-13%, and the linear density is 9.84-84.96tex. The yarn has the advantages of high strength, low elongation, good softness, good pilling resistance and the like, the market requirement is met, and the living standard of people is improved.

Description

technical field [0001] The invention relates to a yarn and a preparation method, in particular to a yarn with high-strength elongation viscose staple fiber as a raw material and a preparation method, belonging to the technical field of textile manufacturing. Background technique [0002] High-strength and low-elongation viscose staple fiber (product name: Yacel) is made of 100% natural bio-based materials. It is a kind of strength and elongation index similar to Modal fiber. It has good water absorption, air permeability, and skin-friendly Sexual new textile fiber raw materials. It has high strength and low elongation fiber characteristics, and its dry breaking strength and wet breaking strength are about 40% higher than ordinary bio-based short fibers. It can be widely used in vortex spinning, siro spinning and siro compact spinning 80S In the above high-count yarn field, the product price is 5,000 yuan per ton lower than that of modal fiber, which has a very high cost per...
