Abstract

The invention provides a preparation method of antibacterial anti-wrinkle linen-cotton fabric. The method comprises the following steps: (1) ultrasonically treating the linen-cotton fabric with an aqueous solution of triethanolamine; (2) preparing amino-modified silver nanoparticles; (3) modifying 2,3-epoxypropyltrimethyl ammonium chloride by a carbodiimide solution, then crosslinking with the amino-modified silver nanoparticles, aminated graphene, and chitosan, and drying the materials; and (4) adding a dried product obtained in the step (3), tea polyphenol, malic acid, tartaric acid, tripolymaleic acid, nano TiO2, antimony trioxide, an osmotic agent, and fibroin to an aqueous solution of ethanol to prepare a finishing agent, and performing dip padding on the fabric to obtain the antibacterial anti-wrinkle linen-cotton fabric. The linen-cotton fabric prepared by the invention has good inhibition effect on Escherichia coli, Staphylococcus aureus and Candida albicans, and has good anti-wrinkle performance. Therefore, the fabric made by the invention has broad application prospects as the antibacterial anti-wrinkle fabric.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of an antibacterial and anti-wrinkle cotton and linen fabric. Background technique [0002] Cotton and linen fabrics are highly recognized in modern textile and apparel applications due to their good hygroscopicity and comfortable wearing. However, cotton and linen fabrics are very easy to breed bacteria in a humid and warm environment. Under suitable conditions, the sugar in cotton fibers can even be used as nutrients for microorganisms, which will not only cause fabric discoloration and mechanical damage, but also threaten human health. , it can be seen that it is necessary to hinder and inhibit the metabolism and reproduction of microorganisms during fabric storage and use. Using antibacterial agents to finish textiles to inhibit and kill harmful bacteria is an important method to prepare antibacterial fabrics, but the long-term use of tradit...
