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.
Claims24
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.
