SURFACE SHEET FOR WOUND DRESSING AND WOUND DRESSING
First Claim
1. A surface sheet for a wound dressing,the surface sheet being disposed on at least a portion of the wound dressing which portion is to face a wound site andcomprising a resin sheet material having a first surface which is to face the wound site, a second surface which is the opposite surface to the first surface, and a large number of penetration pores penetrating through the sheet material from the first surface to the second surface in the thickness direction,the penetration pores allowing the permeation of a liquid from the first surface to the second surface, andthe first surface being hydrophobic.

Abstract
Disclosed is a wound dressing which can retain exudate to prevent it from spreading over a larger area while maintaining a moist environment, can be easily peeled off after use, can prevent skin redness, heat rash, or offensive smell, and can fit various shapes of wound surfaces. The wound dressing is provided with a liquid-permeable layer (1) on the surface to be used to face a wound site (15). The liquid-permeable layer (1) comprises a resin surface sheet (10). The surface sheet (10) comprises a first surface (11) which is to face the wound site (15), a second surface (12) which is the opposite surface to the first surface, and a large number of penetration pores (13) penetrating through the sheet from the first surface (11) to the second surface (12) in the thickness direction. The penetration pores (13) allow the permeation of a liquid from the first surface (11) to the second surface (12). The first surface (11) is hydrophobic.

30. A process for producing a wound dressing comprising at least any one of a liquid-permeable layer, a liquid-permeation restricting layer and an absorbing retaining layer,
the process comprising the step of partially applying a hot-melt adhesive to, among the surfaces of the layers, any of the surfaces which is to face another layer, and stacking the another layer on the applied surface to join each other.
