Abstract
A process is described for false twist texturing polyester filament yarn at greatly enhanced speeds while inserting comparable twist levels and obtaining comparable yarn bulk without increasing yarn heat setting lengths. The process is particularly adopted to the utilization of partially oriented yarns in a draw texturing operation utilizing friction twisting as the means for simultaneously drawing and heat setting the yarn in a twisted state.
