A process for the combined scouring and bleaching of polyester/cotton fabrics at low temperature

Abstract

Optimisation of a low‐temperature combined scouring and bleaching process for polyester/cotton fabric using triethanolamine hydrochloride‐activated sodium chlorite as bleaching agent and a self‐emulsifiable solvent composition as scouring agent has been carried out. The effect of various parameters, namely bleaching agent concentration, time and temperature of treatment, has been investigated by a factorial design methodology.
