NON-CIRCULAR POLYESTER FIBERS CONTAINING SILICONE AND/OR COPOLYMERS HAVING IMPROVED CROSS SECTIONAL SHAPE RETENTION AND A PROCESS TO PRODUCE THEM |
摘要 |
A melt extrusion composition made by combining about 99.9 to about 98.5 weig ht percent of at least one polyester and about 0.1 to about 1.5 weight percent additive provides for a polyester or copolyester non-circular cross sectiona l fiber having at least four percent improved shape retention as compared to t he same fiber made from a melt extrusion composition without the additive. The additive is present at the air-polymer interfacial surface during melt spinning. A method of making the fiber is also disclosed.
