Abstract
A composite article comprises a fluid transport layer having first and second surfaces and a hydrophobic layer applied to the first surface of the fluid transport layer. When the composite article is used as a wound dressing, the first surface of the fluid transport layer provides a skin-facing surface. The hydrophobic layer comprises a plurality of discontinuities, and at least a portion of the discontinuities have a dimension sufficient to permit the passage of fluid through the hydrophobic layer and into the fluid transport layer.
Claims22
A composite article comprising:
- (a) a fluid transport layer, the fluid transport layer having a first surface and a second surface, the first surface of the fluid transport layer having a first surface energy, and the second surface of the fluid transport layer having a second surface energy, the second surface energy being greater than the first surface energy, and
- (b) a hydrophobic layer applied to the first surface of the fluid transport layer, the hydrophobic layer having a third surface energy, the third surface energy being less than the first surface energy, the hydrophobic layer comprising a plurality of discontinuities, at least a portion of the discontinuities having a dimension sufficient to permit the passage of fluid through the hydrophobic layer and into the fluid transport layer,
- wherein the fluid transport layer is a jersey knit textile material comprising a first yarn forming a plurality of interlocking loops and at least one effect yarn tucked into the interlocking loops formed by the first yarn, wherein the plurality of interlocking loops formed by the first yarn provide the second surface of the fluid transport layer, and wherein the first yarn is more hydrophilic than the effect yarn.
