Antibacterial finishing process of pure cotton knitted underpants

Abstract

The invention discloses an antibacterial finishing process of pure cotton knitted underpants. The antibacterial finishing process comprises the following steps: (1) performing antibacterial pretreatment, namely, washing bleached pure cotton knitted underpants, and removing anion residues; or washing off flooding of the pure cotton knitted underpants, and removing anion residues, wherein the unlubricated friction color fastness of the pure cotton knitted underpants is higher than or equal to grade 4, and the lubricated friction color fastness of the pure cotton knitted underpants is higher than or equal to grade 3; (2) performing antibacterial treatment, namely, dipping the washed pure cotton knitted underpants in an antibacterial agent, wherein the antibacterial agent is a cationic polymer antibacterial agent, the o.w.f of the antibacterial agent is 1.5-2.0%, the dipping bath ratio of the antibacterial agent is 1:(10-15), and the primary pH value of the dipping bath ratio is 7.5-8.0; (3) performing softening treatment, namely, dipping the pure cotton knitted underpants after the antibacterial treatment into a softening agent, wherein the o.w.f of the softening agent is 1-3%, and the dipping bath ratio of the softening agent is 1:(10-15). By adopting the antibacterial finishing process, the antibacterial agent can be solidly combined with fiber, so that long-lasting washing-resistant antibacterial properties can be achieved, and the requirements of grade A products in the industrial standard FZ / T 73023-2006 of the Antibacterial Knitwear can be met.

Description

technical field [0001] The invention relates to the technical field of antibacterial finishing of textiles, in particular to an antibacterial finishing process of pure cotton knitted underwear. Background technique [0002] Germs (including pathogenic bacteria and fungi) are everywhere. The secretions, sweat, sebum and other substances absorbed by textiles are excellent nutrients for germs. The foul smell can easily cause skin infections and even diseases. [0003] Underpants are personal products. Currently, the underpants sold in the market have different fabrics and various colors. There are many styles for consumers to choose from. Some underwear also have antibacterial function. However, the antibacterial performance of existing antibacterial underwear is mainly through its The drug ingredients contained in the fabric are realized, and the combination of the drug and the fabric is realized by soaking, sticking, etc., and its binding force is weak. In addition, because ...

[0003] Underpants are personal products. Currently, the underpants sold in the market have different fabrics and various colors. There are many styles for consumers to choose from. Some underwear also have antibacterial function. However, the antibacterial performance of existing antibacterial underwear is mainly through its The drug ingredients contained in the fabric are realized, and the combination of the drug and the fabric is realized by soaking, sticking, etc., and its binding force is weak. In addition, because the drug itself has a certain activity, the stability of its chemical composition is poor. , after wearing or washing for a period of time, its antibacterial performance will decrease rapidly, or even disappear completely. In addition, there is also the problem of not having a wide antibacterial spectrum; Larger, more secretions and sweat, faster germ reproduction, and longer wearing time of underwear, so it is more necessary for underwear to have long-term antibacterial properties
