To make it possible to maintain hydrophilicity at a skin contact surface side material even after the body fluid, such as urine or menstrual blood, is excreted several times by using a non-woven fabric which is mainly composed of polyolefin or polyester based fibers and is treated with sericin on its fiber surfaces as the skin contact surface side material.
A throw-away diaper 1 is constituted by having a liquid penneable surface material 2, a liquid impermeable rear surface material 3 and a liquid holdable absorber interposed between the front and rear surface materials 2 and 3. A belly side waist part 5 existing on the belly side of a wearing person at the time of wearing and a back side waist part 5' existing on the back side are formed. At this time, the non-woven fabric which is mainly composed of the polyolefin or polyester based fibers and is treated with the sericin on its fiber surfaces is used as the front surface material 2 which is the skin contact surface side material. The sericin is one kind of protein and is obtainable in a refining stage for cocoon yarn. The non-woven fabric is formed by impregnating the raw non-woven fabric with the sericin, then insolubilizing the sericin, thereby adding the sericin to the fabric.
