ABSTRACT:
A burn sheet comprising a plurality of layers laminated one to another and including a liquid-permeable top layer, a liquid-absorbent layer and a strength-imparting scrim layer. The scrim layer comprises an open pattern of crossing multifilamentary yarns bonded on one another at their crossings. The scrim is flattened prior to its incorporation into the burn sheet laminate so that cut ends of the scrim yarn monofilaments yield to the touch and the sheet is rendered conformable, and telegraphing of the scrim to the surface of the sheet is minimized. The sheet is suitable for use as a transfer sheet as well as for a burn sheet.
