摘要

Biquaternary ammonium salt CY and cationic surfactant DAB were investigated as pretreating agents for surface modification of cotton fibers. The measurement of zeta potential was used to indicate the effectiveness of the pretreatment. It was found that CY and DAB both largely enhanced the positive charge on cotton fibers following an increase in the pH. Adsorption studies of gardenia yellow dye on these pretreated cotton fibers showed that both CY and DAB enhance adsorption capacity of gardenia yellow dye on cotton fibers. The zeta potential results and adsorption studies revealed that the uptake of gardenia yellow dye on treated cotton fibers occurs via electrostatic attractions between the anion of the dye and cationic segments of the treated cotton fibers. The washing fastness and crocking fastness of the dyeings were improved after the pretreatments.
