Five yarn samples were prepared at five different heater temperatures, viz. 185, 195,205, 215 and 225°C, and the fabric samples were produced by using these yarns in weft. With increase in heater temperature, the yarn tenacity increased up to 205°C and then decreased. Heberlein crimp contraction had a direct relationship with temperature and so had the fabric width shrinkage. The flexural rigidity of the fabric decreased with increase in temperature up to 215°C and then increased while the crease recovery angle decreased warp-wise and increased weft-wise with increase in temperature. The dye upake of the fabric decreased with increase in heater temperature up to 205°C and then increased.</span>
