Application of plant antimicrobial pigments in antibacterial textiles
In order to understand the application progress of plant antimicrobial pigments in textiles,so as to obtain better natural plant dyed antibacterial textile products,the application advantages of natural plant antibacterial agents are reviewed,including their molecular structure,pigment extraction scheme,dyeing process,antibacterial properties of several typical plant antibacterial pigments and their application in fabrics.It has been pointed out that antibacterial durability is the technical bottleneck of popularization and application of plant dyed antibacterial textile,and suggestions are made from the following four breakthrough point to develop durable antibacterial plant fabrics:One is the antibacterial properties of plant dye extracts;The second is the stability of the molecular structure of plant antibacterial pigments;The third is the optimization plan for pigment extraction and dyeing process;The fourth is the antibacterial durability of plant dyed fabrics,which refers to the adsorption fastness,hydrolysis resistance,oxidation resistance,acid and alkali resistance,and friction resistance of plant dyed fabrics during use.
