Abstract

The invention belongs to the technical field of textile material preparation and relates to a long-acting antibacterial fabric rich in silver ion fibers and a preparation method of the long-acting antibacterial fabric rich in silver ion fibers. The method includes: firstly, subjecting oak bark fibers and citric acid to mixed soaking, and defiberizing preliminarily; secondly, mechanically defiberizing through a wooden hammer to obtain degummed oak bark fibers; thirdly, soaking the oak bark fibers in N-methylmorpholine solution to obtain pre-modified fibers; fourthly, mixing the pre-modified fibers with water, performing high-temperature high-pressure cooking, mixing with mussel mucin solution, adding catechol oxidase, and performing reaction to obtain modified oak bark fibers; fifthly, mixing the modified oak bark fibers with sodium polyphosphate and silver nitrate solution, and performing reaction to obtain self-made sliver ion fibers; finally, compounding the silver ion fibers, polyurethane fibers and viscose fibers to finally obtain the long-acting antibacterial fabric rich in silver ion fibers. According to detection data in a table as shown in the specification, the long-actingantibacterial fabric has remarkable antibacterial effects and long antibacterial action, thereby having a promising application prospect.

Description

technical field [0001] The invention relates to a long-acting antibacterial fabric rich in silver ion fibers and a preparation method thereof, belonging to the technical field of textile material preparation. Background technique [0002] The improvement of living standards has promoted the rise of fitness sports and leisure life, thus increasing people's demand for leisure sportswear, and putting forward higher requirements for the comfort and health care functions of clothing. This has promoted the development of functional clothing fabrics. People's body temperature will rise during exercise, and they will also sweat to varying degrees. Although sweating will not be formed in many cases, this will cause the microclimate between the clothing and the human body to be in a state of high temperature and high humidity, thus making the human body Bacteria are very easy to breed on the skin and clothing in contact with human skin, which affects people's health. For microorgani...
