DYEING METHOD OF POLYESTER TEXTILE FOR IMPROVING DYEING CHARACTERISTICS

摘要

PURPOSE: A method for dyeing a polyester fabric is provided to modify the surface of the polyester fabric using chitosan-acetic acid solution and to improve leveling property and color fastness. CONSTITUTION: A method for dyeing a polyester fabric comprises: a step of modifying the surface of the polyester fabric using an antimony free nontoxic catalyst; a step of dyeing the polyester fabric using a dyeing solution containing a chitosan-acetic acid solution and a solution containing one or more disperse dyes; and step of reduction-cleaning the fabric using sodium hydrosulfite or sodium hydroxide.
