Abstract

The invention discloses a cationic surfactant and application thereof and discloses the antibacterial property, mildew resistance, flexibility and anti-yellowing property of cationic quaternary ammonium myristylmethyl dihydroxyethyl ammonium bromide which is used as a clothing antibacterial finishing agent of cotton fabrics and non-woven fabrics. Antibacterial experiments performed on the cotton fabrics and the non-woven fabrics processed by the cationic surfactant with different mass concentration prove that the novel cationic surfactant has the remarkable effect of killing escherichia coli and staphylococcus aureus and also has a certain suppression effect on aspergillus niger, penicillium funiculosum and chaetomium globasum when the mass concentration of the surfactant is 1.0g/L; tests on the flexibility and anti-yellowing property of cotton fabrics processed by the surfactant with different mass ratios prove that the flexibility of the fabrics is most excellent when the mass ratio is 0.25%, and the fabric finished by quaternary ammonium is good in anti-yellowing property.

Description

technical field [0001] The invention relates to a cationic surfactant and its application. Background technique [0002] 1. With the rapid development of the economy, the continuous progress of the society, and the continuous improvement of people's quality of life, people pay more and more attention to the clothes they wear. In addition to the beautiful and trendy styles, people also pursue the excellent performance of the clothes. Single textiles can no longer meet the needs of the public, and textiles with excellent performance after functional finishing are more and more popular. In daily life, microorganisms that are harmful to our human body are ubiquitous and pervasive. Textiles are the closest thing to us. Of course, textiles are also a good place for bacteria and mold to multiply. Our skin secretes sweat every day, and the sebum secreted by the sebaceous glands adheres to our clothes, which provides good nutrients and growth places for bacteria, and bacteria and m...
