Embodiment 1

[0030] 1. Fabric: Pure cotton poplin woven fabric (40x40) after desizing, refining and bleaching;

[0031] 2. For finishing, use 5% glutamic acid aqueous solution prepared by dissolving 20mmol / L phosphate with a pH of 6.8-7.0 at 80°C, soak the fabric at 80°C for 1 hour and dry it at 50°C to make the excess rate 60%; 2% N, N-dimethyl-N-12 alkyl aminopropyl trimethoxy silicon quaternary ammonium salt and 0.5% 16 alkyl trimethoxy silane solution dissolved in 10mM phosphate buffer solution with a pH of 6.8-7.0 , soak the fabric for 1 hour and then dry it so that the excess rate is 50%, and then dry it with air at 50°C; transfer the finished cotton yarn fabric to a 20mM rinse solution with a pH of 5.0, soak it for 1 hour, drain and dry it, and then transfer it to a 20mM rinse solution with a pH of 5.0. Soak in 10mM rinsing solution for 1 hour, drain and spin dry (ie, double soaking and double tying treatment), until the residual rate is 30%; then bake at 120°C for 1 hour, then turn...

Abstract

The invention discloses a method for finishing cotton yarn with antibacterial organosilicon quaternary ammonium salt, which belongs to the technical field of textile chemistry. The method of the invention is to strengthen the adhesion density of the organosilicon quaternary ammonium salt to the cotton fiber and improve its antibacterial performance after finishing. The cotton yarn is impregnated with neutral glutamic acid solution, compounded organic silicon quaternary ammonium salt, and weak acid rinsing solution in sequence, and finally baked to complete the finishing, that is, the fiber is negatively charged by pretreatment with neutral 5% glutamic acid to improve For the electrical adhesion of positively charged organosilicon quaternary ammonium salts, use 2% compound quaternary ammonium salts to make it densely attached, then rinse with weak acid to remove glutamic acid, and bake and coke to attach glutamic acid to remove negative charges. After finishing, the adhesion speed, adhesion density and adhesion efficiency of cotton fiber to organic silicon antibacterial quaternary ammonium salt are improved, the antibacterial performance of cotton fabric after finishing is enhanced, and the appearance properties such as softness and moisture retention of finished cotton fabric are improved at the same time. The process is simple, the operation is convenient, the consumption is low and the efficiency is high, and it has application value for finishing cotton yarn for filtering bacteria, preventing bacteria, killing bacteria and killing viruses.

Description

technical field [0001] The invention discloses a method for finishing cotton yarn with antibacterial organosilicon quaternary ammonium salt, which belongs to the technical field of textile chemistry. Background technique [0002] With the improvement of living standards, people's demand for functional textiles is increasing, and antibacterial functional textiles also occupy a very important position. Textile antibacterial agent finishing technology has been applied earlier, such as triclosan, TiO2, silver series, copper series, nickel-chromium alloy, haloamine compound, chitosan polyhexanide, organosilicon betaine and quaternary ammonium salt as There are many applications for such finishes. [0003] Organosilicon quaternary ammonium salt has always been popular because it is non-irritating and non-carcinogenic. In the 1970s, it was discovered that organosilicon quaternary ammonium salt can be antibacterial and antibacterial, and can make textiles have antibacterial, soft, ...
