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.

Dressing

A bandage comprising a fabric formed from at least one layer of nonwoven hydroentangled fibers having a skim coat of adhesive disposed thereon. Subsequent to entangling the fibers, the fabric is compacted to arrange the fabric into a series of wave-like configurations having crests and valleys. These wave-like configurations allow the fabric to stretch when pulled, and recover to most of its original form when the tension is released. After compacting, a light coat of adhesive is applied to the crests of the fabric to impart some slip resistance to the surface of the fabric while leaving the valleys substantially free from adhesive. The adhesive may be applied to one side or both sides of the fabric, depending on the requirements of the fabric. The thusly formed bandage, when stretched for application, has discontinuous areas of adhesives disposed therein that provide sufficient slip resistance while also permitting complete repositionability.

Slip resistant bandage

An absorbent pad such as a disposable diaper having a water-resistant backing sheet, a layer of absorbent material, and a top sheet in the form of a fibrous web with a binder of polymeric material containing at least 1% by weight of combined 2-ethyl hexyl acrylate.
