Adsorption Properties of Cationized Cotton

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. This paper studies adsorption properties of modified cotton. Modification of cotton yarns for achieving electropositive charge and better adsorption properties was carried out by cationization with cationic compound, quaternary ammonium salt in different stages of pretreatment. It is an alternative method for improving dyestuff and surfactant adsorption. Dyestuff adsorption ability and ionic surfactants adsorption ability were investigated.
