Hollow fiber fabrics

Abstract

The present invention is directed to fibrous fabric comprising hollow fibers. Preferably, the fibrous fabrics will have an opacity greater than a fibrous fabric with an equivalent basis weight and made with the same material and the same fiber diameter. The fibrous fabric comprising hollow fibers may also have an opacity greater than a higher basis weight fibrous fabric containing the same material and having an equivalent fiber diameter and the same number of fibers. The perimeter of the hollow region of the hollow fibers is substantially non-concentric to the outer perimeter of the hollow polymeric fibers. The hollow fibers can be monocomponent and multicomponent, as well as monoconstituent or multiconstituent. These hollow fibers are then consolidated into woven and nonwoven fibrous fabrics that are then converted into articles.
