Preparation method of wool-cashmere anti-bacterial blended knitting yarn

Abstract

The invention relates to the technical field of wool-cashmere anti-bacterial blended knitting yarns, in particular to a preparation method of a wool-cashmere anti-bacterial blended knitting yarn. Theyarn is produced through carrying out loose fiber dyeing and anti-bacterial finishing on a blended raw material and then utilizing a semi-worsted process, wherein the blended raw material is formed by10 to 15 percent of cashmere and 85 to 90 percent of mercerized wool; in the loose fiber dyeing process, a low temperature dyeing auxiliary LTD and a wool protective auxiliary HTW are added; and anti-bacterial finishing is carried out after accomplishing loose fiber dyeing. The preparation method of the wool-cashmere anti-bacterial blended knitting yarn obtained through the invention has the advantages that main anti-bacterial factors of an anti-bacterial agent are silver ions, the contact specific surface area of the silver ion anti-bacterial components and a fiber can be increased through the method, fibers are fully adsorbed, the surface silver content of a final finished-product fabric can range from 15 to 50ppm, and an anti-bacterial effect and the durability are improved.

Problems solved by technology

[0002] Most of the wool spinning antibacterial knitting products in the prior art are antibacterial treatment in the fabric finishing process or use natural antibacterial (such as hemp) fibers in the spinning process. Among them, the antibacterial products produced through fabric finishing are High temperature conditions are often required, which will cause damage to the antibacterial agent and affect the antibacterial effect. In addition, the contact surface area between the fabric and the antibacterial agent is small, and the antibacterial agent is mainly concentrated on the surface of the fabric. Disappeared, the overall sustained performance is poor

For products produced by blending with natural antibacterial fibers, in order to achieve a satisfactory antibacterial effect, the blending ratio of natural antibacterial fibers needs to meet certain requirements, so that the product style will change, which will affect the soft, smooth and comfortable feel of the product. And the spinning process will be different, and the production difficulty will increase
