Patent ID: 11266547

Abstract:
A liquid permeable surface sheet (3) includes an upper layer non-woven fabric (20) which is provided at the skin side, and which is hydrophilic, and a lower layer non-woven fabric (21) which is provided at the non-skin side, and which is water repellent. Multiple apertures (22) are formed which penetrate the upper layer non-woven fabric and the lower layer non-woven fabric. Accordingly, body fluid transfers smoothly through the apertures to an absorbent body. The upper layer non-woven fabric at the skin side is made to be hydrophilic such that body fluid readily permeates therethrough. The lower layer non-woven fabric at the non-skin side is made to be water repellent such that the body fluid which has passed through is not readily absorbed again. Accordingly, the backflow amount of body fluid can be reduced.
