Abstract

Cationic dyeable polyester(CDP) was produced through melt blending of cationic chips having $2mol\%$ of sodium salt of dimethyl ester of 5-sulfoisophthalic acid(DMS salt) and normal polyester chips in different proportions to obtain yarns having varying amount of comonomer in the fiber. The modified polyesters showed increased moisture regain, decreased viscosity, lower softening point and improved antistatic characteristics, according to the amount of modifier. In dyeing at $100^{\circ}C$ the dyeing rate of cationic dyes with CDP fiber increased slowly than that of disperse dyes. In dyeing at $120^{\circ}C$ cationic dyes reached to equilibrium at 30min and disperse dyes at 10min. Cationic dyes in dyeing of CDP fabric have a better wash fastness compared with disperse dyes, also rubbing fastness of cationic dyes is better than that of disperse dyes. The light fastness of CDP fabric for cationic and disperse dyes is not good. The fastness of 75d/36f CDP fabric is higher than 75d/72f fabric. Solvent wicking fastness of CDP with cationic dyes is better than that of disperse dyes.
