Problems solved by technology

It can be seen from the above-mentioned existing technologies that at present, pure wool products with excellent quality can be obtained by combining plasma technology and enzyme treatment technology, which is an ideal treatment method at present, but the cost of pure wool is relatively high, and the removal of wool scale layer must To a certain extent, the performance of wool itself has been changed, and the more complicated processing technology has further increased the price of wool products, which is not conducive to market promotion.

Abstract

The invention provides a shrink-proof wool composite yarn, which includes wool fiber and chemical fiber. The wool composite yarn has a sheath-core structure. In the sheath-core structure, the cortex is wool fiber, the core layer is chemical fiber, and the surface of the chemical fiber contains 2 ‑3 rotating grooves, the scales on the surface of the wool fiber are embedded in the rotating grooves of the chemical fiber to form a better fit, and then the shrink-resistant wool composite yarn is obtained through twisting and mechanical heat pressing. The preparation process of the invention is simple, the cost is low, and the color and feel of the wool will not be affected, and the obtained shrink-proof wool composite yarn retains the excellent characteristics of the wool itself, and has good dimensional stability.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a shrink-proof wool composite yarn and a preparation method thereof. Background technique: [0002] Products made of pure wool have always been loved by consumers because of their warmth, breathability, strong hygroscopicity, good elasticity and rich hand feel. However, products made of pure wool are more expensive and more complicated in daily care. It is difficult to recover after shrinking. Wool shrinks because of its unique microstructure and nature. The surface of wool contains scales. The scales will expand and expand when stimulated by water flow, temperature difference or static electricity. structure, and with the movement process, each wool is constantly entangled, deformed, retracted, displaced, and tightly entangled, that is, the common shrinkage deformation. [0003] Wool shrink-proof methods include chlorination treatment, oxidase treatment,...
