<p>A process is described for false twist texturing a synthetic multifilament yarn by friction twisting means wherein the bleeding of real twist through the false twisting zone is arrested, thereby eliminating a source of yarn streaking in dyed goods produced from said yarns. The process involves sequentially passing multifilament yarn to be textured through a heated zone, a cooling zone, a false twisting zone, and a yarn separation zone to a take-up zone, wherein friction twisted yarn is backed up in the twisted state into the heated zone wherein it is heat set, passed through a cooling zone and hence through said friction twisting zone where the yarn is untwisted to substantially remove twist and hence through a yarn separation zone wherein the yarn is separated into at least two plies, thereby arresting twist prior to taking up the yarn.</p> |
