Anti-fungus and mothproof coating for textiles

Abstract

The invention discloses an anti-fungus and mothproof coating for textiles, comprising the following components by weight parts: 10-30 parts of polyurethane, 10-20 parts of pyridine copper sulfate, 10-15 parts of alcohol, 1-10 parts of chitosan and 1-5 parts of sodium tripolyphosphate. The coating is prepared by the following steps of: dissolving the polyurethane in the alcohol, dissolving the chitosan in 0.5-1.5 wt% of acetum, dissolving the pyridine copper sulfate in chitosan solution, then, adding the polyurethane alcohol solution into the chitosan solution, slowing adding the sodium tripolyphosphate, simultaneously, stirring at high speed and executing ultrasonic processing, finally, obtaining the coating. The anti-fungus and mothproof coating has the following positive effects that: the coating is high-efficiency, low-toxicity, broad-spectrum, long-acting, antibacterial to various microorganisms, strong in antibiotic property and high in safety, can keep integrity and efficiency for longer time, and has no influence on strength of gray fabrics.

Description

technical field [0001] The invention relates to an anti-mildew and anti-moth coating for fabrics, belonging to the field of textile chemistry. Background technique [0002] During the weaving process of fabrics, the starch size on the yarn and gray cloth is the most suitable source of nutrients for bacteria to multiply. Therefore, weaving shafts and gray cloths that need to be stored for a long time, especially export gray cloths. Mildew spots are prone to occur under the conditions of high air humidity and poor ventilation. In order to prevent moldy textile fabrics, antifungal agents are generally added to the slurry. [0003] Moreover, in the middle and lower reaches of the Yangtze River, because of the unique rainy season, it is very suitable for the growth and reproduction of mold, which can easily cause mildew and rot in textile products, which not only causes losses, but also causes harm to the health of consumers.
