摘要: Abstract The purpose of this work was to develop a textile finish based on radical UV-curing chitosan cotton and silk confer antimicrobial properties. Fabrics were impregnated with solution 2% w in aqueous acetic acid (2% v/v) added 2-hydroxy-2-methylphenylpropane-1-one w/w respect chitosan) as photoinitiator cured at room temperature by exposure UV lamp for 60 s both the sides. activity finished fabrics tested according ASTM standard test performed Escherichia coli . Obtained results showed strong conferred treatment, homogeneous fabric surface, without affecting hand properties due low weight (about 2%). treatment durability domestic laundering after 5 cycles using either anionic or nonionic detergents. resulted completely maintained washing surfactant, while detergents better samples prepared deeper penetration inside fibers. characterized dyeing tests, SEM FTIR-ATR analyzes.
