This research had an aim for studying the printing process of LACCIFER LACCA KERR. (LAC) on cotton and polyester fabric. The Lac dye was extracted by using Sodium hypochlorite solution Sodium hydroxide Hydrogen peroxide and diethyl ether then Acetic acid was used for dye sedimentation. Thenthe printing condition and color fastness to washing crocking and light were examined. The efficiency of solution for extraction process were found Diethyl ether > Sodium hypochlorite solution > Sodium hydroxide > Hydrogen peroxide respectively. The hot air was suitable fixation process for cotton and polyester printing. The cotton fixation was 150oC for 5 minutes it is 11.87 in color strength. And the polyester fabric was fixed at 220oC for 3 minutes the 8.27 color strength was shown. The both of cotton and polyester were printed with Lac dye had the good color fastness to crocking and light and moderate in washing fastness. This study can apply the Lac dye on cotton and polyester fabric by a printing technique without mordanting. Then it can reduce some chemicals in the textile printing industry. This process can applied and transfer for small enterprise for Lac value added appication.
