Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2020 / V.32,no.1,Mar Title Chemical Warfare Agent Simulant Decontamination of Chitosan Treated Cotton Fabric Authors Woong Kwon, Minwoo Han, and Euigyung Jeong* Institution/Affiliations Kyungpook National University Pages/Total page pp.51 ~ 56 / 6 Language Korean Abstract This study aims to pursue the multi-functional textile finishing method to detoxify chemical warfare agent by simply treating the well-known antimicrobial agent, chitosan, to cotton fabric. For this purpose, DFP(diisopropylfluorophosphate) was sele cted as a chemical warfare agent simulant and cotton fabric was treated with 0.5, 1.0, and 2wt% chitosan solution in 1wt% acetic acid. DFP decontamination properties of the chitosan treated cotton fabrics were evaluated and compared with the untreated cotton fabric. The chitosan treated cotton fabrics showed better DFP decontamination than the untreated cotton. Decontamination properties of the chitosan treated cotton fabrics improved with the increased chitosan solution used. Especially, the cotton fabrics treated with 2wt% chitosan solution showed 5 times more DFP decontamina tion than the untreated cotton fabrics. This suggested that the chitosan treated fabric has potential to be used as a material for protective clothing with chemical warfare agent detoxifying and antimicrobial properties.
