Embodiment 1～10

[0021] At room temperature, mix the solubilizer and emulsifier uniformly with the solvent diethylene glycol monobutyl ether in the required ratio, and then gradually add the required amount of antibacterial agent to it under stirring, and continue to stir until the system It is clear and transparent, and antibacterial additives are prepared for use.

Embodiment 11～18

[0040]The antibacterial additive is added to the acrylic fiber spinning dope (the total solid content of the dope is 12% by weight) with the sodium thiocyanate aqueous solution (concentration of 51.3% by weight) as the spinning solvent through the online injection device, and the spinning dope is passed through a static mixing Maker, so that the antibacterial additives and the original liquid are evenly mixed. According to the general wet spinning process conditions for spinning and post-processing (post-processing procedures include cold drawing, water washing, hot drawing, oiling, dry densification, crimping and heat setting, etc.), the fineness is 1.67dtex Of antibacterial acrylic. During the entire spinning process, the pressure of the nozzle assembly and the filter did not change abnormally, and the spinning process was smooth.

[0041] See Table 4 for the addition amount of antibacterial agent in the spinning dope and the antibacterial test results in Examples 11-18. In Tabl...

Abstract

The invention relates to a manufacturing of antibacterial acrylon, which adopts a wet spinning process that takes sodium sulfocyanate aqueous solution as solvent. Antibacterial additive is added to spinning solution and evenly mixed with the same to obtain a fiber product after the processes of spinning and post-processing, wherein the antibacterial additive is a solution which comprises the components of antibacterial agent, solubilizing agent, emulsifying agent and solvent; the antibacterial agent is A or the mixture of A and B, wherein A is 2, 4, 4'-trichloro-2'-dihydrox diphenyl ether, B is selected from 4-chlorine-3, 5-oylenol or 2, 4-dichloro-3, 5-xylenol, and the weight ratio of A and B is 1 : 0-0.3; the solubilizing agent is hydrogenated castor oil polyoxyethylene ether-60; the emulsifying agent is selected from one or the mixture of more than two of Tween-20, Tween-40. Tween-60 or Tween-80; and the solvent is diethylene glycol monobutyl ether. The manufacturing method of antibacterial acrylon takes the total solid of the spinning solution as a standard, and the addition amount of the antibacterial agent according to weight proportion is 0.5-2.2 percent. The invention solves the technical problem that the compatibility between the antibacterial agent and the spinning solution is poor.

Description

Technical field [0001] The invention relates to a method for manufacturing antibacterial acrylic fibers, in particular to a method for manufacturing antibacterial acrylic fibers by adopting a wet spinning process using an aqueous sodium thiocyanate solution as a solvent. Background technique [0002] In recent years, while pursuing the comfort of chemical fiber fabrics, people also pay more and more attention to the health care function of fabrics. Among them, antibacterial fabrics with antibacterial 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 fiber has good warmth retention and moisture permeability, and is easy to blend with wool and cotton. It is suitable for making underwear, socks and other close-wearing fabrics. Therefore, antibacterial acrylic fiber is very The research and development of ideal antibacter...
