Abstract
Abstract 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.
