  Abstract

Silk textile has been used for a long time owing to its soft texture and luster. However, its limited elasticity has restricted its textile application causing end users to demand silk textile with improved features such as good extensibility and elasticity. In this study, the silk textile was prepared with high twist silk yarn and subjected to heat treatments to augment its elasticity. The effect of heat treatment on the morphology and mechanical properties of silk textile was examined. As the water temperature and drying temperature increased, the shrinkage ratio of silk textile increased causing the weft silk yarn to become tangled. Further, the breaking strength of silk textile decreased and its elongation increased significantly. Most silk textiles, except the ones immersed in water and dried at 25 ℃, showed an elastic recovery of 100%. However, the results of tough repetitive extension tests (at 150% elongation condition) showed a small permanent extension of silk textile at the end of the first extension cycle.
