Preparation method of special antibacterial wool fiber for wool hat

Abstract

The invention discloses a preparation method of a special antibacterial wool fiber for a wool hat. The preparation method comprises the steps of dipping the wool fiber in acetone, airing after washing, adding into a mixed aqueous solution of sodium cyanate and hydrogen peroxide, airing after dipping, and irradiating through an ultraviolet light to obtain a pretreated wool fiber; adding thiourea, urea and butyl titanate into absolute ethyl alcohol for mixing, adjusting a pH value, adding deionized water for stirring until a Tyndall effect occurs, standing for ageing, drying, grinding, and calcining to obtain modified nanometer titania; adding chitosan into an acetic acid aqueous solution, adjusting a pH value, adding the modified nanometer titania, adjusting a system pH value, adding glutaraldehyde after temperature rising, standing for reacting, centrifuging, washing, and drying to obtain modified chitosan; adding the modified chitosan, a plant extract, beta-cyclodextrin and a silane coupling agent KH-550 into the deionized water, and stirring to obtain an antibacterial solution; adding the pretreated wool fiber into the antibacterial solution for padding processing, and baking after drying.

Description

technical field [0001] The invention relates to the technical field of wool hats, in particular to a preparation method of special antibacterial wool fibers for wool hats. Background technique [0002] Wool is a widely used natural protein fiber, which has the characteristics of soft touch, good elasticity and good warmth retention. Wool hats are made from wool and are daily necessities for people. They can be used for decoration, sunshade and warmth, and are very popular among consumers. However, as a natural protein fiber, wool itself does not have antibacterial function. Wool hats made of it often provide a "hotbed" for bacteria to survive, and are prone to breed bacteria during use, posing a certain threat to human health and the environment. . Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a preparation method of special antibacterial wool fiber for wool hats. The process is si...
