Abstract

The invention discloses a preparation method of functional fiber, particularly relates to an antibacterial cellulosic fiber or antibacterial cellulosic fiber product and a preparation method thereof, and belongs to the technical field of after-trimming of textiles. According to the antibacterial cellulosic fiber or antibacterial cellulosic fiber product and the preparation method thereof, a soluble starch aqueous solution and a silver nitrate solution are mixed uniformly, and a fibroin aqueous solution is added to obtain fibroin nano-silver colloid, and after being added with a protein aqueous solution, carrying out padding treatment on a cellulosic fiber or cellulosic fiber product subjected to selective oxidation treatment, so as to obtain the antibacterial cellulosic fiber or antibacterial cellulosic fiber product. According to the technical scheme, nano-silver is attached to the surface or the interior of the cellulosic fiber stably for a long time, and simultaneously the cellulosic fiber or cellulosic fiber product is endowed with the protein property, and has the characteristics of being long-acting in antibacterial function and good in washability.

Description

technical field [0001] The invention relates to a preparation method of functional fibers, in particular to a preparation method of antibacterial protein-coated cellulose fibers, and belongs to the technical field of textile finishing. Background technique [0002] Antibacterial textiles can increase the added value of products and meet people's needs for health and environmental protection. Therefore, more and more textile researchers pay more and more attention to them, and the market potential is huge. Although common cellulose fiber products have the advantages of wearing comfort, renewability and biodegradability, due to their large specific surface area and strong moisture absorption capacity, they are very easy to attach microorganisms or pathogenic bacteria during consumption. And create conditions for its reproduction and spread, resulting in strong fiber damage, stains, fading, unpleasant odors, and even the spread of diseases, affecting human health. Therefore, r...
