Abstract
Processes for forming synthetic fibers from polymer melts containing a first fiber forming polymer, a spin assist additive, and optionally a pigment additive are provided. Also provided are synthetic fibers of a first fiber forming polymer, a spin assist additive, and optionally a pigment additive, as well as articles of manufacture such as yarns, carpets and fabrics made up of these synthetic fibers.
Claims34
A process for forming a synthetic fiber, said process comprising the steps of:
- (a) producing a polymer melt comprising a first fiber forming polymer and a spin assist additive, wherein the spin assist additive is present in a range from about 0.5 to about 5 percent by weight;
- and
- (b) forming a synthetic fiber from the polymer melt.

A synthetic fiber comprising:
- (a) a first fiber forming polymer;
- and
- (b) a spin assist additive present in the synthetic fiber at a range from about 0.5 to about 5 percent by weight, wherein the spin assist additive is a polyamide comprising at least one aliphatic diamine and at least two distinct aromatic dicarboxylic acids, and copolymers and blends thereof.
