Background

Cotton fabrics are one of the common fabrics in the textile field at present, but single-function cotton fabrics have difficulty in meeting the pursuit of people for high-quality life. The cotton textile has the excellent properties of ventilation, moisture absorption, heat resistance, acid resistance, softness, close fitting, warmth retention and the like, and is widely applied to living aspects, but the antibacterial function of the pure cotton textile is relatively poor, and the structure and the property of the pure cotton textile are extremely easy to cause bacterial breeding, so that the cotton textile is endowed with more excellent antibacterial function and has extremely important significance. The traditional antibacterial finishing of cotton fabrics mainly surrounds two mechanisms, namely a, contact type durable sterilization and b, release sterilization components for antibacterial (dissolution type antibacterial). Among them, materials used in the method based on contact persistent sterilization are chitosan, guanidine salt polymer, halamine compound, betaine, etc. materials, which generally adsorb bacteria to the bacteria when they come close together, and a large amount of charge distribution can cause rupture of bacterial cell membranes. Antimicrobial methods based on release of antimicrobial components typically pre-load or embed the antimicrobial agent and then use it in antimicrobial finishing of cotton fabrics such as silver nanoparticles, various antibiotics, and some metal oxides, etc. However, these materials have certain adverse effects on human physiology, including skin allergy, erythema and other inflammatory adverse reactions, so that the application of these materials is limited.
