Abstract

The invention provides a functional antibacterial composite wool flocculus. The functional antibacterial composite wool flocculus is mainly prepared from wool composite fiber webs, hot melting powder and silver nanoparticles, wherein the mass of the hot melting powder accounts for 7%-13% of the total mass of the wool composite fiber webs. The functional antibacterial composite wool flocculus has the advantages of being breathable, high in moisture removal property and capable of promoting sleep, enhancing the vitality, promoting cell metabolism, delaying ageing and inhibiting pathogenic bacteria and can effectively prevent many skin lesions and pruritus. The invention further provides a preparation method of the functional antibacterial composite wool flocculus. The method is simple, easy to operate and suitable for large-scale automated production.

Description

technical field [0001] The invention belongs to the technical field of textiles. Specifically, the invention relates to a functional composite antibacterial wool flake and a preparation method thereof. Background technique [0002] In the daily environment, wool fiber has good heat preservation function, can release negative ions slowly and evenly, and has high anti-mold ability. Among them, wool flakes are a common variety of hot-melt nonwovens, and nonwovens are sheets made of directional or disordered fibers by friction, cohesion or bonding or a combination of these methods. Wool composite fiber web or wadding, also known as non-woven fabric, non-woven fabric, non-woven fabric, non-woven fabric, which combines the advantages of chemical fiber, textile, paper, plastic and leather. [0003] The specific production process of wool flakes is as follows: the mixed wool fibers are evenly fed to the carding machine through the feeding hopper, and the single-layer wool composite...
