Abstract

The invention relates to a nano-silver antibacterial blended fabric. The nano-silver antibacterial blended fabric is manufactured by the following steps: performing light-shielded oxidation reaction on a blended fabric formed by interweaving warp yarns composed of 50% of cotton, 30% of flax and 20% of bamboo fibers with weft yarns composed of 100% of cotton in a sodium periodate solution; preparing a pure silk fibroin solution; then, dipping the oxidized blended fabric in the silk fibroin solution for reaction; and finally, dipping the fibroin grafted blended fabric in a silver nitrate solution, taking the blended fabric out of the solution, and heating the blended fabric in a 800W microwave oven for 5 minutes to obtain the nano-silver antibacterial blended fabric. According to the invention, the cotton / flax / bamboo fiber blended fabric is taken as a base material, the nano-silver antibacterial blended fabric is generated by silk fibroin in situ through a microwave radiation method, and the surface of the fabric is grafted with a layer of silk fibroin, so that the fabric is endowed with hand feeling and gloss similar to those of silk.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a nano-silver antibacterial blended fabric. Background technique [0002] Although natural cellulose has the advantages of wearing comfort, renewability and biodegradability, but in the process of taking, because the fiber has a large specific surface area and strong moisture absorption capacity, fiber products are very easy to attach microorganisms, and for Its reproduction and propagation create conditions that cause damage to fiber strength, stains and discoloration, unpleasant odors, and even the spread of diseases, affecting human health. Therefore, in the research on the modification of cellulose, an important research direction is to realize the antibacterial properties of cellulose and reduce the damage of bacteria to the human body. Nano-silver is often used as an antibacterial finishing agent due to its safe, non-toxic and efficient antibacterial properties, and its long-lastin...
