Abstract

The invention provides a preparation method of antibacterial wool flocculus. The preparation method mainly comprises the following steps: supplying a kind of wool flocculus, a nanometer silver dispersed solution and a reducer; and impregnating the wool flocculus in the nanometer silver solution to carry out impregnation reduction, and then carrying out press-rolling and drying treatment to obtain the antibacterial wool flocculus. The preparation method is simple and feasible and is suitable for automation production in a large scale. Meanwhile, a product prepared by the preparation method has the characteristics of air permeability, strong moisture exhaust performance and capabilities of promoting sleep and cell metabolism, enhancing vitality, delaying aging and inhibiting germs, and can effectively prevent various skin lesions and pruritus.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular, the invention relates to a preparation method of antibacterial wool flakes. 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 flakes or flakes, also known as non-woven fabrics, non-woven fabrics, non-woven fabrics, non-woven fabrics, which combine the advantages of the five major materials 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 flakes output by the c...
