Abstract
Embodiments of the disclosure include elastomeric stretch fibers containing an anti-tack agent, methods of preparing the fiber, methods of using this fiber, articles including this fiber, and the like.
Claims42
An article comprising:
- a fiber comprising an elastomeric propylene based polymer and an anti-tack agent, said fiber being substantially free of a silicone-based finish.
An article comprising an elastomeric fiber comprising:
- about 60% to about 95% by weight of an elastomeric propylene based polymer;
- and
- about 0.5 and 30% by weight of an anti-tack agent, wherein the elastomeric fiber is substantially free of a silicone-based finish.
A method of spinning an elastomeric propylene based polymer fiber comprising:
- providing an elastomeric propylene based polymer;
- mixing an anti-tack agent with the elastomeric propylene based polymer, wherein the mixing occurs during preparation of the elastomeric propylene based polymer or during melt-spinning;
- melt-spinning the polymer/anti-tack mixture into a fiber;
- and
- winding the fiber, wherein the fiber is adapted to be unwound without the application of a silicone-based finish to the surface of the fiber prior to winding.
