[0028] The invention provides a kind of preparation method of fabric antibacterial agent, concrete steps are as follows:

[0029] (1) First disperse the nano-silicon carbide in the ethanol aqueous solution to form a nano-silicon carbide dispersion. Under the dark condition, add the nano-silicon carbide dispersion to the silver nitrate solution, adjust the pH value of the solution to about 6-10, and react Time 2-8h, use a centrifuge to separate, clean with deionized water after separation, and dry to obtain nano-silver composite particles;

[0030] (2) Put 80-100 parts of deionized water in a clean stirring tank and start stirring;

[0031] (3) Add 5-15 parts of nano-silver composite particles and 1-5 parts of silane coupling agent, at a speed of 500-1000 rpm, stir for 20-30 minutes until completely mixed;

[0032] (4) Add 10-30 parts of butyl chitosan and 1-5 parts of triethanolamine, at a speed of 500-1000 rpm, stir for 20-30 minutes until completely mixed;

Abstract

The invention discloses preparation and application of a textile antibacterial agent. The antibacterial agent is prepared from the following raw materials in parts by weight: 5 to 15 parts of nano-silver composite particles, 10 to 30 parts of butyl-chitosan, 1 to 2 parts of tetrakis hydroxymethyl phosphonium sulfate, 1 to 2 parts of sodium hexametaphosphate, 1 to 5 parts of triethanolamine, 1 to 4 parts of sodium laurate, 1 to 5 parts of vaseline, 1 to 5 parts of a silane coupling agent and 80 to 100 parts of de-ionized water. The textile antibacterial agent disclosed by the invention has the advantages of good antibacterial effect and long lasting time and does not contain heavy metal and organic halogens so that harmful effects on the environment are not caused. Moreover, a preparation technology of the textile antibacterial agent is simple and industrialized popularization is easy to realize.

Description

technical field [0001] The invention relates to an antibacterial agent in the field of textile materials, and more specifically, the invention relates to an antibacterial agent with good antibacterial effect, long duration, no heavy metal and organic halogen, and no adverse effect on the environment. Background technique [0002] With the continuous improvement of people's living standards, the demand for antibacterial materials and antibacterial clothing will continue to increase, especially as medical clothing, which is an ideal product for effectively protecting medical staff and patients, and the daily clothing market with antibacterial functions is even more For the vast.
