Problems solved by technology

At present, the methods of antibacterial finishing of textiles using chitosan are all antibacterial finishing through processes such as soaking, dehydration, pre-baking, and baking. Cross-linking, the amount of cross-linking, the uniformity and fastness of the cross-linking reaction are relatively low, which directly affects the durability of the antibacterial effect, and high-temperature baking wastes a lot of steam and electric energy

Embodiment 1

[0030] (1) Pretreatment of pure cotton clothing

[0031] The bath ratio is 1:20-1:50, and the sodium hydroxide solution with a mass concentration of 10g / L-20g / L is prepared, and the pure cotton clothing is treated at 80°C-100°C for 15min-60min. Soak in acetic acid solution with a concentration of 0.5%-5%, fully wash with clean water, dehydrate, and dry for later use;

[0032] (2) Plasma surface activation treatment of pure cotton clothing

[0033] Put the pre-treated and dried pure cotton clothes into the microwave plasma reaction chamber, the reaction chamber is evacuated to a vacuum of 5Pa-50Pa, and air, oxygen, nitrogen, argon, and hydrogen are introduced at a flow rate of 0.8L / h-6L / h Or the mixed non-polymerizable gas of the above gases, maintain the vacuum degree at 50Pa-220Pa, turn on the microwave power switch, activate the microwave plasma to activate the surface of pure cotton clothing for 0.5min-4min, and continue to maintain the vacuum degree of the reaction chambe...

Abstract

The invention discloses a chitosan antibacterial finishing method for textiles. Firstly, it is pretreated, and then the surface of the fiber is activated with a large amount of high-energy electrons, ions and free radicals generated by microwave plasma; , flush the antibacterial finishing agent containing chitosan with a certain temperature into the reaction chamber by using the negative pressure in the reaction chamber to react with the activated clothing for a certain period of time, then dehydrate the finished clothing to maintain the liquid retention rate between 30-60%; and microwave-dried it, finally rinsed with clean water, dehydrated, dried, and packaged. The pure cotton garment of the present invention exhibits good durability after chitosan antibacterial finishing, and after 60 times of soaping, the antibacterial rate of Escherichia coli is still over 80%, and the antibacterial rate of Staphylococcus aureus is over 89%.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, relates to the functional finishing technology of finished garments and home textile products, is an antibacterial finishing of finished garments that can be applied to woven garments and knitted garments, and specifically relates to a chitosan antibacterial finishing method for textiles . Background technique [0002] With the improvement of living standards, people's demand for textiles is not only limited to styles and colors, but also has an increasing desire for the function of clothing. Clothing, home textile products, especially underwear and underwear that are worn next to the body, towels, bath towels, and bedding used every day It is easy to breed bacteria. Antibacterial finishing of this kind of textiles can alleviate the damage to the human body caused by various bacteria bred by the textiles due to absorbed sweat and human body shed dander. At present, the meth...
