PRODUCTION OF YARN COVERED WITH COCOON YARNS

摘要

PURPOSE:Cocoon yarns are put together with the core yarn, which is undergoing false twisiting, at a speed faster than the running of the core yarn and passed through the false-twisting means to give the titled yarn giving woven or knitted fabrics with silk yarn's luster and touch. CONSTITUTION:The core yarn such as wool spun single yarn 1 is passed through the guide 2 and drawn out by the feed roller 3, false-twisted by the means 4 and taken out by the delivery rollers 5. In the meantime, cocoon yarns 8 from cocoons in the reeling baths 9 are passed through the guides 11 and reeled by means of the feed rollers 12, then put together with the core yarn 1, which is undergoing false twisting, between the core yarn feed rollers 3 and the false twisitng means. At this time, the feed speed of the cocoon yarns 8 is made higher than the taking-up speed of the core yarn 1 by the delivery roller 5 and the core yarn 1 is covered with the cocoon yarns 8, then they are passed through the false twisting means 4, taken up with the delivery rollers 5 and wound up with the frction roller 6 around the bobbin 7, thus giving the objective yarn.
