Problems solved by technology

[0012] Natural antibacterial agents mainly include chitosan, protamine, cassia bark and luohan tar, etc., most of which are refined from animals and plants. They have the advantages of excellent weather resistance, low toxicity, and safe use. The main disadvantage is heat resistance. Poor, short duration of efficacy

Embodiment 1

[0029] A method for preparing an antibacterial finishing agent for textiles, comprising the following steps;

[0030] Step 1 Add 232 parts of deionized water, 11 parts of surface-modified nano-titanium dioxide, 6 parts of hexadecyltrimethylammonium bromide, and 5 parts of OP-10 into the reactor, stir, and heat up to 68-72 °C; 0.5 Part of initiator sodium persulfate is dissolved in 20 parts of deionized water for stand-by;

[0031] Step 2: Add the initiator aqueous solution and 24 parts of dimethyl diallyl ammonium bromide, 6 parts of 3-vinylaniline, and 3 parts of diallylamine dropwise to the reactor simultaneously within 2 hours. After the dropwise addition, Then heat-preserve and react at 75°C for 1 hour;

[0032] Step 3: Lower the temperature of the reactor to 45-50°C, add a solution of 0.2 parts of silver nitrate and 20 parts of deionized water, stir well, then quickly add a solution of 0.2 parts of sodium borohydride and 20 parts of deionized water to carry out the reduc...

Abstract

The invention relates to preparation method of antibacterial finishing agent of textile apply, belonging to textile assisting agent field. The antibacterial finishing agent for textile apply is prepared from zircoaluminate coupling agent, nanometer titanium dioxide, quaternary ammonium monomer, deionized water, and polymerization initiator synthetically react prepared; by mass, 7-11 parts of zircoaluminate coupling agent, 13-18 parts of nanometer titanium dioxide, 27-39 parts of quaternary ammonium monomer, 117-153 parts of deionized water, 0.8-1.3 parts of polymerization initiator. The method adopts the step of quaternary ammonium monomer after modification nanometer titanium dioxide ion surface grafting, restrict controls quaternary ammonium in basal body, compounds inorganic and organic antibacterial agent, overcomes the weaknesses that nanometer titanium dioxide light touch media loses antibacterial property at dim light and quaternary ammonium safety property appears poor and creates micro organism agent resistance, the finishing agent chemical stability stays poor, tolerates heat poor and more related weaknesses, helps achieves antibacterial agent safety, persistence, and efficiency property.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial finishing agent for textiles, in particular to an antibacterial finishing agent for textiles, belonging to the field of textile auxiliaries Background technique [0002] Antibacterial agents commonly used in textiles can be divided into several categories such as inorganic, organic and natural. [0003] 1. Inorganic antibacterial agent [0004] Inorganic antibacterial agents can be divided into metal ion type and photocatalytic type. [0005] (1), metal ion type [0006] Using the antibacterial ability of silver, copper, zinc and other metals, through physical adsorption and ion exchange, etc., silver, copper, zinc and other metals (or their ions) are fixed on the surface of porous materials such as zeolite and silica gel to make antibacterial agent, and then add it to the product to obtain a material with antibacterial properties. Metals such as mercury, cadmium, and lead have the s...
