<p>Improved PVC filaments for use as wig material for toy dolls are described. PVC resin may be mixed with a stabilizing agent, lubricants, and a processing aid and pounded into PVC resin pellets. The PVC resin pellets may be subsequently spun or extruded in a conventional spin-draw machine. Undrawn PVC filaments are oil-coated and drawn at differential temperatures on a plurality of roller sets prior to heat-setting and being wound on a take-up unit.</p> |
