Manufacturing method for elastic fiber having fur-like touch, elastic fiber having fur-like touch made from the same, and fabric woven by said fiber
A manufacturing method for elastic fiber having fur-like touch elastic fiber having fur-like touch made from the same, and fabrics woven by said fiber is provided to improve the defects caused by the conventional wool fiber or lack in the elasticity, wearing comfortability and maintenance of fabric having fur-like touch. Two kinds of thermoplastic polymer in different heat shrinkage rate by using same spinnerette arranged in side by side in the way ofmelt conjugate spinning to form conjugate fiber having spiral structure like spring. Elastic thermoplastic polymer is adopted to central core yarn, general thermoplastic fiber or modified thermoplastic polymer of crystalline retarded by third component is used to peripheral effect yarn, and by means of draw-twister, draw-winder or other filament combination equipment with heat setting and air entanglement, spin texturing to get a combined n filament heat draw yarn.then said combined filament yarn is subjected to twisting heat setting, warping or battening to weave or knit to fabric, then via fabric finishing and processing. High temperature treatment makes core yarn of combined filament yarn elastic due to heat shrinkage difference and makes effect yarn of combined filament yam low Young's modulus. This leads to elastic fiber having fur-like touch and fabrics woven by said fiber.
