Problems solved by technology

[0003] But there are many deficiencies in the antibacterial finishing agent for fiber yarn and cloth at present, the function is particularly single, it is difficult to meet the needs of modern people, and there are often following defects:
[0004] 1) Most of the existing antibacterial finishing agents for clothing fabrics have varying degrees of toxicity, teratogenicity, mutagenicity and carcinogenicity. Although the antibacterial finishing agents themselves have certain antibacterial effects, they are easy to damage the fabrics and the human body after treatment. Health produces certain side effects;
[0005] 2) At present, many antibacterial finishing agents have poor durability and reusability, and the antibacterial finishing agents of clothing fabrics themselves cannot carry out repeated finishing processes; secondly, the antibacterial effect of clothing fabrics after each finishing is difficult to maintain for a long time , prone to failure

Abstract

The invention discloses an antibacterial finishing agent for fiber yarn and cloth and a preparation method thereof. The antibacterial finishing agent is calculated in parts by weight and consists of the following components: 1-10 parts of modified tourmaline nano powder, poly 0.2-2 parts of allyl dimethyl ammonium chloride, 0.5-5 parts of hydroxyethyl cellulose, and 100 parts of deionized water. The antibacterial finishing agent prepared by the present invention is safe and has no side effects on the human body, and tourmaline can emit negative oxygen ions and emit infrared rays, which has a beneficial effect on the health of the human body; and the antibacterial finishing agent of the present invention has strong reusability, Can play a long-lasting strong antibacterial effect.

Description

technical field [0001] The invention relates to the field of antibacterial finishing agents for fiber yarns, in particular to an antibacterial finishing agent for fiber yarns and cloths and a preparation method thereof. Background technique [0002] With the development of society and the improvement of people's living standards, people pay more and more attention to the comfort and functionality of fabrics. As a fabric worn next to the body, it has higher requirements for comfort, not only requires a super soft hand, but also has high requirements for its antibacterial properties and skin-friendly properties. [0003] But there are many deficiencies in the antibacterial finishing agent for fiber yarn and cloth at present, the function is particularly single, it is difficult to meet the needs of modern people, and there are often following defects: [0004] 1) Most of the existing antibacterial finishing agents for clothing fabrics have varying degrees of toxicity, teratoge...
