Faser mit verbesserten Eigenschaften, Zusammensetzung zur Herstellung solcher Fasern und Verfahren zur Verbesserung von Fasereigenschaften

摘要

An improved polyester fiber, polymer composition for producing such fibers by spinning and drawing, and a process for improving the production of fibers from polyester is disclosed wherein an aliphatic diester such as ethylene glycol distearate is incorporated into the polyester resin prior to spinning fibers from the resin in trace amounts of from about 0.01 to about 0.4 percent by weight of the polyester. The composition improves the process of spinning and drawing fibers from the resin and produces superior fibers.
