A kind of composite structure slub yarn and its production process

Abstract

The invention discloses composite structure bunchy yarn and a production technology thereof. The composite structure bunchy yarn comprises bunchy yarn A and winding yarn B, and the winding yarn B is wound on the surface of the bunchy yarn A, and the mass ratio of the winding yarn A to the winding yarn B is (30-60%): (40-70%), and a siro tight spinning technology is adopted to obtain the compositestructure bunchy yarn; the bunchy yarn A is blended by flax fiber and super high molecular weight polyethylene fiber, and then through the steps of pretreatment of flax, pretreatment of the super highmolecular weight polyethylene fiber, a blending technology of the flax fiber and the high molecular weight polyethylene fiber, pretreatment of spun silk fiber, a blending technology of spun silk andmodal fiber and a spinning technology of the composite structure bunchy yarn, the production technology of the composite structure bunchy yarn is completed. Through pretreatment of the spun silk, theflax and the super high molecular weight polyethylene fiber before spinning, the problem that during spinning of the spun silk and the super high molecular weight polyethylene fiber, static electricity is severe is effectively solved, the flax is effectively softened, and the spinnability of the spunk silk, the flax and the super high molecular weight polyethylene fiber is improved.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to a composite structure slub yarn and a production process thereof. Background technique [0002] Flax fiber is hygroscopic and breathable, and is a good material for summer clothing. However, flax fiber has a large lignin content, thick and hard fibers, and large yarn hairiness, which causes itching to the skin; UHMWPE has good heat transfer performance and high strength, and is also Good clothing material, but ultra-high molecular weight polyethylene fiber has too much molecular weight, high fiber rigidity, poor cohesion, difficult spinning, and large yarn hairiness. [0003] Modal fiber is a high wet modulus cellulose regenerated fiber developed by Austrian Lenzing Company. It has good hygroscopicity and air permeability. Its crystallinity is small, the fiber is soft and smooth, and has a strong silky texture. , still supple after repeated washing, full o...
