1. Anti-bacterial and anti-odor finishing
At present, most of the antibacterial sanitary finishing agents for textiles are bactericides. For example, AV-990, a silicone sterilizing and deodorizing finishing agent, is a new type of sterilizing and hygienic finishing agent based on high molecular weight organosilicon ammonium salt polymer. It uses active groups in silicone polymers to graft cationic groups with bactericidal properties onto the surface of the fiber, which can kill negatively charged bacteria. It mainly uses cationic groups to penetrate the surface membrane of bacteria, causing the bacteria to flow out and achieve sterilization. This finishing agent belongs to the virtually non-toxic grade, has no obvious irritation to the skin, and does not show skin allergic reactions. It is a safe new antibacterial sanitary finishing agent. Finishing process: AV-990, 0.7%-1.0% (o.w.f.), temperature 30-50℃, liquor ratio 15-20:1, this sanitary finishing agent is suitable for textiles of all types of fibers.
2. Anti-insect finishing
As a protein natural animal fiber, cashmere fiber is very easy to be eaten by insects. At present, ordinary households mainly use sublimated substances such as camphor and naphthalene. The gases emitted by such substances are also harmful to humans and have carcinogenic effects on humans. Moreover, their validity period is short, and moths are prone to produce antibodies. The moth-proof finishing agent JF-86 can make cashmere have long-term and effective moth-proof function, and at the same time overcome the shortcomings caused by naphthalene and extend the service life of cashmere products. It can be used in the same bath with dyes during the cashmere dyeing process. It is simple and convenient to operate, does not affect the dyeing process, and its insect-proof effect reaches level 2 of the International Wool Bureau grade standard. The recommended dosage of finishing agent JF-86 is 0.5%-0.6%. There is basically no change in the color light and color fastness of the sample, and it has good stability. In addition, the washing resistance of the product is also very good. It can still maintain good anti-moth performance after multiple washings. It has been washed 9 times and still reaches level 2 of the International Wool Bureau grade standard. Therefore, it can obtain a long-lasting anti-moth effect and facilitate storage by consumers. custody.
