Abstract

Higher productivity in spinning of polyester partially oriented yarn is achieved by using high intrinsic viscosity polymer i.e. 0.65-0.95, a hot zone below the spinneret wherein solidification is prevented i.e. 255 DEG -350 DEG C, a cooling zone below the hot zone wherein the streams are solidified into filament in the substantial absence of the customary transverse cooling air flow, and converging the filaments into a yarn preferably on a surface supplied with a liquid spin finish.
