Abstract

The invention discloses an organosilicon quaternary ammonium salt finishing method for the antibacterial treatment of a cotton yarn, and belongs to the technical field of textile chemistry. The methodstrengthens the adhesion density of the organosilicon quaternary ammonium salt on a fiber of the cotton yarn and the antibacterial property of the cotton yarn is improved after finishing. The cottonyarn is sequentially leached in a neutral glutamic acid solution, a compound organosilicon quaternary ammonium salt, and a weak acid rinsing solution, and is finally baked to finish finishing, the neutral glutamic acid with the concentration of 5% is used to pretreat to charge the fiber with the negative charge, the electric adhesion of the organosilicon quaternary ammonium salt with the positivecharge is improved, the compound quaternary ammonium salt with the concentration of 2% is used in finishing to achieve dense adhesion, then the weak acid rinsing solution is used to rinse to remove the glutamic acid, and the negative charge is removed by baking and coking the adhered glutamic acid. The adhesion speed, the adhesion density and the adhesion efficiency of the fiber of the cotton yarnon the organosilicon antibacterial quaternary ammonium salt are improved after finishing, the antibacterial property of the finished cotton yarn fabric is strengthened, and meanwhile, the appearanceperformances like softness and moisture retention of the finished cotton yarn fabric are improved. The process is simple, the operation is convenient, the consumption is low, the efficiency is high, and the method has an application value in the aspect of filtering and blocking bacteria and killing bacteria and 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, ...
