ABSTRACT:
A procedure is provided for producing a wound dressing having a crushed or uncrushed foam bonded to a woven, knit or nonwoven absorbent layer, particularly woven cotton gauze. The foam is self-bonded to the absorbent layer, i.e., no adhesive is needed to bond the foam. The foam may be applied by one of several methods. One procedure comprises applying a thin layer of foamed latex on a release medium. The dry foam, still on the release paper, is then simultaneously crushed and transfer bonded to the absorbent layer. A second method comprises applying the foam directly on the absorbent layer and crushing if desired. A third method comprises applying unfoamed material on the fabric and then causing foaming by the use of blowing agents then crushing if desired.
