Embodiment

[0014] The antibacterial treatment method of the woolen cloth of the present embodiment comprises the following production steps:

[0015] 1. Prepare chitosan antibacterial finishing solution, heat chitosan and citric acid in water at 60°C for 8 hours, then stir evenly, the concentration of chitosan is 0.25%, and the concentration of citric acid is 0.5%%;

[0016] 2. Put the wool fabric into the chitosan antibacterial finishing solution, soak it at room temperature for 30 minutes, and then put it on a vertical electric rolling trolley for pad dyeing. The rolling rate is 82%, and then repeat soaking and rolling again;

[0017] 3. Put the woolen cloth into a constant temperature oven and dry it at 80°C for 5 minutes, then put it into a baking machine and bake it at a high temperature for 2 minutes at a temperature of 120°C;

[0018] 4. After drying, soak in woolen washing liquid for 5 minutes, then rub and rinse for 2 minutes each, and then dry it.

Abstract

The invention discloses a woolen cloth antibacterial processing method. The method comprises the following steps: adding a chitosan solution and a critic acid solution into water with a temperature of 60 DEG C, heating the water for 8 hours, then evenly stirring, wherein the concentration of the chitosan solution is 0.25%, and the concentration of the critic acid solution is 0.2% to 1%; soaking the woolen cloth into a chitosan antibacterial finishing agent for 30 minutes at a room temperature, subjecting the woolen cloth to a pad-dyeing treatment on a vertical electrical dyeing trolley, wherein the mangle expression is 80% to 90%, then repeating the soaking treatment and the rolling process for another time; drying the woolen cloth in a constant-temperature oven for 5 minutes at a temperature of 80 DEG C, then carrying out a high temperature baking treatment for 2 minutes in a baking machine at a temperature of 120 DEG C; soaking the dried woolen cloth in a woolen detergent for 5 minutes, rolling the woolen cloth for two minutes, rinsing the woolen cloth for two minutes, and finally naturally drying the woolen cloth in the air. The processing method is simple and reasonable. The processed woolen cloth has a good antibacterial performance and washing resistant performance.

Description

[0001] technical field [0002] The invention belongs to the technical field of fabrics, and in particular relates to an antibacterial treatment method for woolen fabrics. Background technique [0003] Worsted wool has a unique and elegant style. It is used to make uniforms and coats. It is crisp yet soft, simple yet stylish, and rough yet elegant. It is very popular, but woolen is prone to bacteria and mold growth. And reproduction provides rich nutrition, causing mildew, odor, and even spreading disease. [0004] Chitosan, like other polysaccharides, contains highly active functional groups in its complex spatial structure, exhibits the characteristics of antibiotics, and can inhibit the growth and activity of various bacteria. A large number of experiments have shown that chitosan has an inhibitory effect on Escherichia coli. The study found that at a pH value of 5.5, at a concentration of 0.5% and 1%, it can be completely inactivated after a two-day incubation period. ...
