Abstract: An interlabial pad, which is fitted between labia and absorbs menstrual blood and other body fluids, and a surface side sheet used in this interlabial pad are presented. The surface side sheet is used in the interlabial pad that is fitted between labia and has a fiber aggregate having a wet shear strength with respect to labial inner walls of no less than 15 cN/25 mm and no more than 60 cN/25 mm when containing an artificial menstrual blood at a content of 800%. The artificial menstrual blood being a fluid composition includes water, glycerin, sodium carboxymethylcellulose, sodium chloride, sodium bicarbonate, and a food dye preparation. Even when the shape of the labia changes because of movement of a wearer in a highly wet state after absorption of menstrual blood, since the shear force that arises between the labial inner walls and the interlabial pad can be resisted, positional deviation and falling off of the interlabial pad can be prevented.

Abstract: Here are disclosed a composite non-woven fabric having a high dimensional stability and a process for preparing such non-woven fabaric. This non-woven fabric is prepared by a cross-stretching starting non-woven fabric obtained by a fiber entanglement treatment of a staple fiber web by fluid jets to form a substrate, then introducing short fibers onto this cross-stretched substrate and filling said cross-stretched substrate with said short fibers by further fiber entanglement treatment also by fluid jets. Such composite non-woven fabric is suitable particularly as cloth for disposable medican garments or the like.
