Sažetak
Cotton fibers, like most textile fibers, are negative charged in neutral and alkali aqueous solutions. Dyestuffs, optical brighteners and finishing agents in aqueous solution have the same electrical charge as cotton, so adsorption processes are difficult due to repulsive forces. It is well known that for overcome these forces in dyeing processes, a large amounts of electrolyte is needed, what is economically and ecologically unfavorable. This paper studies the cotton modification for achieving its electropositive charge and better dyeing properties. Modification of cotton yarns was carried out with quaternary ammonium compound in different stages of pretreatment for the purpose of lowering the zeta potential of cotton. It is one of alternative method to low the high electrolyte amount in dyeing bath. For this purpose, raw and bleached cotton yarns were cationized with 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride (CHPTAC) before and during the mercerization process
