Water-absorbing sanitary underwear

Abstract

To provide water-absorbing sanitary underwear capable of improving diffusibility of body fluid and inhibiting liquid return.SOLUTION: Water-absorbing sanitary underwear (1) is reusable underwear having: a surface layer (10); an absorption layer (20) disposed on a non-skin surface side (T2) of the surface layer; and a waterproof layer (30) disposed on the non-skin surface side of the absorption layer. The surface layer and the absorption layer mainly include non-water-absorbing fibers. The water repellency of the skin surface of the surface layer is higher than the water repellency of the non-skin surface of the surface layer. The absorption layer has an intake region (25) in which the density increases from a skin surface side toward the non-skin surface side. The intake region has a diffusion portion (27) including fibers oriented in a planar direction.SELECTED DRAWING: Figure 6
