PROCESS FOR PRODUCING POLYESTER DIFFERENTIAL SHRINKAGE BLENDED WOVEN YARN

摘要

One manufacturing method of the polyester air bulky yarn with different shrinkage is arranged to make to have the yarn suede of uniform tension to interweave, and installs a roller by the rear side in a cross connection device. One manufacturing method of the polyester air bulky yarn with different shrinkage includes the following steps:: one heart yarn of weaving and effect yarn difference (S1); Execute the solidification on heart yarn (S2), attached drawing, and heat treatment; In conjunction with heart yarn and effect yarn, have a unstretched condition (S3); It shifts the heart yarn combined and effect yarn enters a cross connection device; Yarn suede is set to interweave, when maintaining to be tensioned equably (S4). Heart yarn passes through a heating roller. Effect yarn passes through a non-thermal roller.
