Causticizing of viscose/lycra (95/5) knit fabric

摘要

Viscose treatment needs high care and know how because viscose fabrics are more susceptible to the chemical processes. In this study, caustisizing which is generally found to be dangerous in the pretreatment of the viscose fabrics was applied to the viscose fabrics. It was found that the usage of caustic soda in the pretreatment of viscose fabrics ensured considerable advantages in terms of pilling degree and colour efficiency in textile dyeing. After causticization, the surface of the fabrics became smoother and fuzzy of the fabrics decreased. In addition, performing a caustic treatment before dyeing with reactive dyestuff caused an increase in the colour efficiency.
