This study has been undertaken to see the variation of the weight loss, dyeing property, and the tensile strength of the polyethylene terephthalate (PET) fabrics under the influence of the heat setting during the finishing of the fabrics. The fabrics were heat set for 40,80 and 120 seconds, then alkali treated with 5%, caustic soda solution for 40 minutes on temperature of 80℃, and then dyed with blue and red disperse for 30 minutes of the temperature of 130℃, Using these treated materials, color differences and tensile strength were measured. The results were as follows; 1. The weight loss of PET fabrics increased as the heat setting temperature was elevated. 2. weight loss of PET fabrics decreased as heat setting time increased on the temperature over 220℃ 3. The dyeing property of PET fabrics became stable on the temperature below 180℃ not influenced by heat setting time. 4. The tensile strength decreased as the weight loss increased. Consequently, the temperature influences greatly on the weight loss and the dyeing property during the finishing of PET fabrics.
