Problems solved by technology

[0004] The technical problem mainly solved by the present invention: Aiming at the problems that the traditional organic antibacterial agents are rapid and effective in inhibiting and killing bacteria, but have side effects on the human body, bacteria are prone to drug resistance, poor timeliness and high temperature resistance, a composite antibacterial fiber is provided The preparation method of the invention, the invention mixes waste silk and chitosan, acidifies after treatment to obtain acidified silk powder, then takes expanded vermiculite as carrier particles after calcining, loads acidified silk powder on the carrier particles, and uses sodium alginate solution Soak the coated carrier particles, mix them with cattle feed, feed the cattle, modify them through the rich microorganisms inside the cattle, collect the carrier particles from cow dung, mix them with chitosan, etc., and pass the modified silk in microwave And under ultraviolet irradiation, supplemented with vermiculite catalysis, it is easier to modify the grafted antibacterial substance, and finally the powder can be obtained by ultrasonic vibration and sieving. The composite antibacterial fiber prepared by the present invention belongs to natural antibacterial agent, which is highly effective in antibacterial and has no effect on the human body. Safe and no side effects, bacteria do not produce drug resistance, stable and long-lasting antibacterial performance, and rich sources of raw materials, simple preparation process, low cost

Abstract

The invention discloses a preparation method of a composite antibacterial fiber, which belongs to the field of antibacterial fibers. In the present invention, waste silk and chitosan are mixed, acidified after treatment to obtain acidified silk powder, and then expanded vermiculite is calcined as carrier particles, acidified silk powder is loaded on the carrier particles, and soaked in sodium alginate solution to obtain coating Carrier particles, mixed with cattle feed, fed cattle, modified by the rich microorganisms inside the cattle, collected carrier particles from cow dung, mixed with chitosan, etc., passed through the modified silk, under microwave and ultraviolet irradiation , at the same time supplemented with vermiculite catalysis, it is easier to modify the grafted antibacterial substance, and finally the powder can be obtained by ultrasonic vibration and sieving. The composite antibacterial fiber prepared by the present invention belongs to the natural antibacterial agent, which has high antibacterial effect and is safe for the human body without side effects. Bacteria do not produce drug resistance, the antibacterial performance is stable and long-lasting, and the source of raw materials is abundant, the preparation process is simple, and the cost is low.

Description

technical field [0001] The invention discloses a preparation method of a composite antibacterial fiber, which belongs to the field of antibacterial fiber. Background technique [0002] With the advent of the era of antibacterial products, research on antibacterial fibers has become the focus of attention in the fiber industry. Viscose fiber has always been considered as a high-grade textile material due to its excellent hygroscopicity, smooth and cool, breathable and antistatic properties. Nano-oxides have microporous structure characteristics, small particle size, large specific surface area, a large number of dangling bonds and unsaturated residual bonds on the surface, high surface activity and bonding tendency, and can be made into very good antibacterial properties. Nano-composite antibacterial powder. Due to the easy agglomeration of nanomaterials and poor compatibility with polymers, their application level and scope have been seriously affected. Therefore, many res...
