Napped nonwoven fabric having high bulk and absorbency

摘要

A soft, bulky light weight fabric having good absorbency and suitable for use as a wound dressing is prepared from a hydroentangled nonwoven fabric comprising a plurality of parallel spaced apart ribs interconnected by loose fiber bundles extending between adjacent ribs. The ribs comprise high density, highly entangled masses of fibers and contain at least about 60 percent by weight of the fiber in the fabric. The fabric is napped ina direction perpendicular to the ribs to obtain the soft, bulky fabric without tearing or disrupting the integrity of the fabric.
