In this research, we tested the fertile physical and the sensory properties and the handle of the domestic polyester fabrics were treated with the varying alkaline concentrations and temperatures were tested. The tests were conducted to determine the effects of the alkaline treatment on the changes of the physical and the sensory chrateristics of the domestic polyester fabrics. The results were as follows; 1. When treated with the varying alkaline concentrations from $7.5\%$ to $15\%$ at temperatures from $60^{circ}C$ to $90^{circ}C$, the weight decreasing phenomena were shown to as a linear equations increase in that range. 2. As the weight loss increased, the softness and the smoothness were increased but the fullness and the tightness were decreased. 3. The positive correlations were found between the sensory and the physical properties, and the fullness ana the tightness, while a negative correlation was found between softness and the smoothness. 4. The regression equations obtained by the sensory chrateristics related with the physical chracteristics were as follows ; Softness: y=84.01-0.74x Fullness : y=0.06+0.78x Smoothness: y=88.67-0.82x Tightness : y= 0.34+0.79x
