Problems solved by technology

Organic antibacterial agents have poor toxicological safety and poor chemical stability, which will lead to drug resistance of microorganisms; they are easy to migrate and have poor durability, especially poor heat resistance. Many antibacterial fibers are easy to decompose under high temperature processing.
Natural antibacterial agents are easy to carbonize and decompose at high temperature, so the application range is narrow and the antibacterial effect is poor

Abstract

The invention relates to the technical field of antibacterial fibers, in particular to antibacterial compound polymer fibers. The antibacterial compound polymer fibers consist of a macroporous inner core and an outer wall with mesopores; the macropores are internally filled with extracts of traditional Chinese medicines; the pore diameters of the macropores in the inner cores are 50-150nm; the pore diameters of the mesopores in the outer walls are 10-30nm. The antibacterial compound polymer fibers provided by the invention has the advantages of being long in antibacterial time and good in antibacterial effect, and has development prospect and wide application market.

Description

technical field [0001] The invention relates to the technical field of antibacterial fibers, in particular to an antibacterial composite polymer fiber. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's quality of life, people's demand for textiles is not only good-looking and comfortable. The original single textile material can no longer meet people's needs. Antibacterial materials can inhibit fiber damage. The growth and reproduction of microorganisms not only protects the fiber from the invasion of microorganisms, prevents it from discoloration and mold, but also completely non-toxic and non-irritating to humans when in contact with the skin, and does not cause sensitization to the human body. [0003] At present, synthetic fiber products occupy a very important position in people's daily life and industrial and agricultural production. In order to make synthetic fiber products more widely u...
