Antibacterial processing method for wool fiber

Abstract

The invention relates to an antibacterial treatment method for wool fiber, which comprises the following steps: an organic-inorganic composite antibacterial agent, namely silver-bearing silicon dioxide-chitosan is taken as an antibacterial agent and prepared into a pentabasic antibacterial mother liquor with anhydrous alcohol, deionized water, a diluted hydrochloric acid, a dispering / coupling agent and gamma-vinyltriethoxysilane A-151; the wool fiber is subjected to pre-irradiation of the ultraviolet light, and then immersed into the antibacterial mother liquor for secondary irradiation; and the wool fiber and the silver-bearing silicon dioxide-chitosan composite antibacterial agent generate chemical reaction under the action of a light trigger benzophenone and are combined by means of valence linkage to form an antibacterial film with the thickness of 200 nanometers. The antibacterial treatment method improves the persistence of antibacterial functions of the wool fiber, and the antibacterial rate of the wool fiber is still 98.6 percent after being washed for 50 times. Moreover, the antibacterial treatment method has short process flow, small number of equipment used, quick antibacterial speed, high efficiency and good effect, is easy to prepare the mother liquor, is particularly suitable for performing antibacterial treatment on the wool fiber and pashm fiber, and improves the efficiency by 90 percent compared with the prior antibacterial technology.

Description

technical field [0001] The invention relates to an antibacterial treatment method for wool fibers, belonging to the technical field of antibacterial treatment methods for wool and cashmere products. Background technique [0002] Wool and cashmere are excellent products of animal fibers, which are light, soft, slippery and warm, and have always been considered as a high-grade textile material. [0003] Wool and cashmere fibers are animal fibers, which will adhere to and breed different types of bacteria and molds in the process of cutting, transportation, spinning, storage, etc., which will directly damage the quality of the fibers, and even make it impossible for textile processing, causing great economic losses . Furthermore, wool and cashmere products are generally worn next to the skin. Since people will inevitably produce sweat and dander in their daily activities, this will provide a necessary place and source of nutrition for the growth of bacteria, so that harmful ba...

AI Technical Summary

Problems solved by technology

[0005] There are also many forms of antibacterial treatment methods for wool and cashmere fibers, such as: disinfectant dipping method, surface nanocrystallization method, surface wrapping method, antibacterial agent washing method, etc., but these methods have many disadvantages and shortcomings. Simple physical surface treatment is not resistant to washing and friction, and the durability of antibacterial function is poor; It can carry out short-term antibacterial on the fiber. If the specified time is exceeded, some pathogenic bacteria will still be revived, and the antibacterial effect is poor; The process is complicated, the cost is high, and the pollution to the environment is great; these disadvantages seriously restrict the development of antibacterial treatment technology for wool and cashmere fibers
