WASHABLE SILK WOVEN FABRIC AND PRODUCTION THEREOF

摘要

PURPOSE:To obtain the title silk woven and knit fabric having stretchability and dimensional stability after washing by covering urethane elastic yarn with silk yarn under a specific condition, using the covered urethane elastic yarn as weft in weaving of silk woven fabric, presetting the fabric under heating and finishing while maintaining under low tension. CONSTITUTION:Urethane elastic yarn 3 which is reeled from a core yarn package 1 and fed by a roller 2 is passed through a feed roller 4 and in a shaft of a hollow spindle 5. Silk yarn 8 which is wound on a rotary bobbin 7 inserted into the hollow spindle 5 and made into sheath yarn is fed to the periphery of the core yarn 3 and rotated at 800-1,400T/M to cover the core yarn to give covered yarn 9. Then the covered yarn is used as weft to weave silk woven fabric, which is successively preset at 160-180 deg.C and then finished by maintaining the silk woven fabric under low tension to give the aimed silk woven fabric having 20-40% elongation in the lateral direction, 70-90% elongation recovery ratio and =3% shrinkage percentage of washing.
