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.
Claims11
A burn sheet characterized in that said sheet comprises a plurality of layers including a layer of liquid-absorbent material and a strength-imparting layer comprising a scrim formed of a plurality of multifilamentary yarns, said scrim having a tensile strength of at least about 45 pli and an elongation in either its length or width dimension of not greater than about 30% thereby permitting said burn sheet to be grasped at the side edges thereof and serve as a transfer sheet for a patient disposed theron.
