Abstract

The invention belongs to the technical field of textiles, and particularly relates to a preparation method of an antibacterial and mildew-proof agent for textiles. Flos lonicerae, fruit of cubeb litsea tree and herba houttuyniae are used as basic raw materials, beneficial substances such as ester and acid and the like in the basic raw materials are obtained through explosion and cooking extraction, an antibacterial and mildew-proof basic material is obtained, then activated carbon is used for decoloration, the processed basic material and ethanolamine carry out amidation treatment on ester andthe like in the base material under the action of a catalyst; firstly, active groups are increased; and secondly, the bonding performance with other substances is improved, the mixed particles are used for adsorption, a cross-linking agent is used for cross-linking, and then wrapping is carried out, so that microencapsulation is realized, and the bonding performance with textiles is improved.

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 antifungal agent for textiles. Background technique [0002] Due to its loose and porous structure, textiles can easily absorb sweat and oil secreted by human metabolism, providing a favorable place for the attachment and reproduction of microorganisms. Some bacteria and viruses can survive for several hours to several days on the surface of textiles. A number of studies have shown that the use of antibacterial textiles for medical protection and personal hygiene will greatly improve the overall cleanliness of the environment, reduce the incidence of nosocomial infections, and ensure the safety of patients and medical staff. Therefore, the development and application of antibacterial and antiviral textiles are of great significance. [0003] Antibacterial agents refer to substances that can effectively inhibit the growth ...
