Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2020 / V.32,no.2,Jun Title Comparative Study of Detoxification Properties of 3-Aminopropyltrimethoxysilane and Chitosan treated Cotton Fabric Authors Woong Kwon, Changkyu Kim and Euigyung Jeong* Institution/Affiliations Kyungpook National University Pages/Total page pp.96 ~ 102 / 7 Language Korean Abstract Abstract Recently, it was reported that chitosan or APTMS(3-aminopropyltrimethoxysila ne) treatment to cotton using the simple pad-dry-cure method has potential to prepare textile materials for military chemical warfare protective clothing. However, it is not confirmed which method is more efficient. Therefore, this study aims to quantitatively compare detoxification properties of chitosan treated cotton fabric with those of APTMS treated cotton fabric. Detoxification properties were evaluated using the well-known organic phosphorous nerve agent stimulant, diisopropylfluorophosphate(DF P). With the same amount of chitosan and APTMS on the surface of the cotton fabrics, APTMS treated cotton fabric exhibited 10% higher detoxification properties than chitosan treated cotton fabric based on the rate of DFP hydrolysis and half-live of DFP calculated from the DFP decontamination ratios of the treated cotton fabrics through time. Therefore, APTMS treatment can be more efficient method to prepare the textile materials for military protective clothing than chitosan treatment.
