摘要
In the study, a new treatment with cationic surfactants was proposed to remove deposited disperse dyes from polyester fabrics as an alternative to the traditional reduction clearing process. For this purpose, dodecyltrimethyl ammonium bromide and two gemini cationic surfactants (12-4-12 and 14-4-14) were investigated and the optimum operating conditions were obtained using a central composite design. Findings indicated that gemini cationic surfactants can be considered as the best candidates to remove deposited disperse dyes from polyester fabrics. This was confirmed by the results of the scanning electron microscope images, fastness properties and spectrophotometry.
