Abstract

The invention discloses an anti-pilling and antibacterial wool yarn, which comprises a core layer, an antibacterial nanofiber layer and a covering layer, wherein the core layer is wool yarn, and the wool yarn is woven into a rhombus mesh structure; The antibacterial nanofiber layer is obtained by preparing silver-loaded polyacrylonitrile / titanium dioxide nanocomposite fibers by electrospinning, and covering the surface of the core layer; the covering layer is made of modal yarn at a temperature of 30°. It is obtained by spirally winding the surface of the antibacterial nanofiber layer with a wrapping angle of ‑40°. The invention also provides a preparation method of the anti-pilling antibacterial wool yarn. The anti-pilling and antibacterial wool yarn of the invention has good anti-pilling and antibacterial properties.

Description

technical field [0001] The invention relates to the technical field of yarn production, in particular to an anti-pilling antibacterial wool yarn and a preparation method thereof. Background technique [0002] With the continuous progress and development of society, people's requirements for clothing fabrics are also increasing, especially in the field of wool fabrics. Wool fabrics are favored by many people because of their excellent thermal properties. At present, wool fabrics on the market are mostly produced from sheep wool. Although they have good thermal insulation properties, they are prone to pilling, which greatly affects the appearance of wool fabrics. At the same time, most of the current wool fabrics do not have antibacterial properties. With the increasing awareness of textile hygiene and health care, this will greatly affect the market for wool fabrics. [0003] Chinese invention patent CN103271472A discloses an anti-pilling sweater, which is blended with supe...
