Antibacterial additive for producing antibacterial acrylic fibre

Abstract

The invention discloses an antibacterial additive for producing antibacterial orlon, which is a solution and comprises an antibacterial agent, a solubilizing agent, an emulsifier and a solvent, wherein the antibacterial agent is A or a mixture of the A and B, the A is 2.4.4'-trichloro-2'-dihydroxy diphenyl ether, the B is 4-chlorine-3,5-xylenol or 2,4-dichloro-3,5-xylenol, and the weight ratio of the A to the B is 1:0-0.3; the solubilizing agent is hydrogenated castor oil polyoxyethylene ether-40; the emulsifier is one or a mixture of more than two selected from Tween-20, Tween-40, Tween-60 or Tween-80; and the solvent is diethylene glycol monobutyl ether. The weight ratio of the total amount of the solubilizing agent and the emulsifier to the antibacterial agent is 1-3:1, the weight ratio of the solubilizing agent to the emulsifier is 10:0.5-5, and the content of the antibacterial agent in the antibacterial additive is 6 to 30 weight percent. Compared with an orlon spinning solution taking sodium thiocyanate aqueous solution as the solvent, the antibacterial additive has better solubility.

Description

technical field [0001] The invention relates to an antibacterial additive, in particular to an antibacterial additive used to manufacture antibacterial acrylic fiber by using a sodium thiocyanate aqueous solution as a spinning solvent through a wet spinning process. Background technique [0002] In recent years, while people are pursuing the comfort of chemical fiber fabrics, they also pay more and more attention to the health care functions of fabrics. Among them, antibacterial fabrics with bactericidal or antibacterial functions are very popular, such as antibacterial underwear and antibacterial socks. Antibacterial fabrics are usually made of antibacterial functional fibers with antibacterial properties. Acrylic fibers have good warmth retention and moisture permeability, and are easy to blend with wool and cotton. They are suitable for making underwear, socks and other close-fitting fabrics. Therefore, antibacterial acrylic fibers are very The development of ideal antiba...
