Abstract

The invention relates to a method for preparing nanosilver and finishing a fabric. The method comprises the steps: according to the volume ratio of 100:1-1:1, mixing a 0.01-1 g/L thymol solution with a 0.01-100 g/L silver nitrate solution, carrying out uniform-velocity stirring for 10-600 min under the condition of the temperature of 30 DEG C-80 DEG C, to obtain a nanosilver colloidal solution, repeatedly washing with ethanol and deionized water, centrifuging, carrying out drying treatment to obtain silver nanoparticles, then dipping the fabric into a nanosilver solution with the concentration of 0.01-10 g/L, and dipping for two times and rolling for two times. Thymol is used as a reductant and a stabilizer, and the method has the advantages of simple process, mild reaction, green environmental protection and the like. The prepared nanosilver is used in the textile field, can prepare the blended fabric having multiple efficacies of fragrance, corrosion prevention, sterilization, mite removal, dermatomycosis and tinea disease prevention, and greatly improves the added value of textiles.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a method for preparing nano silver and fabric finishing. Background technique [0002] Textiles are recognized as a medium for the growth of microorganisms such as bacteria and fungi. Microbial communities in nature widely exist in the surrounding environment, and can multiply rapidly once encountering suitable humidity, nutrients and temperature. Microorganisms growing on textiles not only affect the performance of textiles themselves, but also affect the health of users. Therefore, how to suppress or kill the microorganisms attached to textiles, especially the textile industry, is an urgent problem to be solved. [0003] Antibacterial textiles can increase the added value of products and meet people's needs for health and environmental protection. Therefore, they have attracted more and more attention from textile researchers and have great market potential. In the research field of ...
