ABSTRACT
Over recent years interest in cotton blended fabrics has continued to grow. Enhanced or a combination of performance properties can be delivered to the textile such as durability, elasticity, drape or handle above that achieved by use of a single fibre alone. However, problems may be encountered with the fibre quality of certain cellulosic blends where one or more of the fibre(s) in the blend is susceptible to damage during conventional bleaching processes. For this reason, bleaching cannot be performed under harsh conditions and can sometimes require several bleaching stages to attain whiteness. If peroxide is used under low temperature conditions, performance can be improved by reaction with T.A.E.D which forms a strong oxidant which is a highly effective bleaching agent at low temperatures. Experiments have been undertaken to investigate the use of low temperature peroxide/T.A.E.D based bleaching systems for cotton/viscose and cotton/polyamide blends to improve fibre quality by attaining whiteness without compromising fibre strength.
