Abstract

A filamentary yarn is false twist textured by being heat set in a twisted configuration. The twist is imparted to the yarn by contact with the inner surface of a rotating friction insert having a profiled friction surface, the insert being mounted in a rotatable cup. The threadline contacts the friction surface at an angle to the surface and passes from the friction surface through a guide and out of the interior of the friction insert. [US3724196A]
