Migration of Crosslinking Reagents in Cotton Fabric During Resin-Finishing Treatments

Abstract

Migration and distribution of crosslinking reagents during controlled drying of cotton fabric cross linked with dimethyloldihydroxyethylene urea (DMDHEU) and dimethytotatkyl triazone (TAE) has been reported. Effects of different temperatures (60, 70, and 80°C) and times (0 60 min) on rate of drying and migration of DMDHEU reagent have been investigated. Migration and distribution of reagent and drying of crosslinked fabric treated with triazone were studied at 80°C only. Rate of drying for fabrics treated with DMDHEU and dried at different temperature showed similar trends, and the rate of drying increased with an increase in the drying temperature. The sample treated with TAE showed a similar trend, but the rate of drying was higher. The agent migration was highest after 60 min of drying at 60°C and lowest at 80°C. The fabric sample treated with TAE showed a higher rate of migration compared to the corresponding sample of DMDHEU after 10 min of drying. The relationship between agent migration and rateof drying is discussed.
