Claims
- 1. A woven fabric having front and back surfaces and comprising yarns of thermoplastic polymer filaments arranged in warp and fill directions, at least some of said filaments being hollow filaments having at least one longitudinal void, said void of at least a majority of said hollow filaments being collapsed to form collapsed hollow filaments having an oblong exterior cross-section with major and minor dimensions, the major dimension of said cross-section of at least a majority of said collapsed hollow filaments being generally aligned with said surfaces of said fabric.
- 2. The woven fabric of claim 1 wherein all of said filaments of said yarns in one of said warp or fill directions are hollow filaments having at least one longitudinal void.
- 3. The woven fabric of claim 1 wherein said filaments are comprised of nylon polymer.
- 4. The woven fabric of claim 1 wherein said hollow filaments have a denier per filament (dpf) such that the denier per filament at 25% elongation (dpf).sub.25 is about 0.5 to about 20.
- 5. The woven fabric of claim 4 wherein said void of said filaments provides a fractional void content (VC) of at least about [(7.5Log.sub.10 (dpf)+10)/100].
