ABSTRACT:
A dressing comprising a textile-like nonwoven fabric characterized in that the fibers comprise a blend of fibers including a percentage (preferably from about 15 to about 60 percent) of thermoplastic fibers, and the fabric is compacted (preferably micro-creped at an overfeed not less than 10 percent and typically in the range of about 20 to about 30 percent and at a drum temperature of greater than about 250 degrees F.) subsequent to hydro-entangling the fibers. prior to compacting, the fabric typically has a weight in the range of about 20 to 60 grams per square yard. After compacting, the fabric has an absorptive capacity and a liquid transfer both of which are greater than the absorptive capacity and liquid transfer of a hydro-entangled fabric of the same weight and fiber blend which has not been compacted.
