The covering member includes an inner side surface being in contact with the absorber and an outer side surface to come into contact with a vaginal wall when in use. The covering member contains a hydrophobic fiber with a low affinity to water and a hydrophilic fiber with a high affinity to water. In the outer side surface, an abundance ratio of the hydrophobic fiber is higher than an abundance ratio of the hydrophilic fiber.

Here is disclosed a composite sheet comprising substantially non-stretchable nonwoven fabric sheets and a plurality of elastic members extending in a transverse direction and spaced one from another in a longitudinal direction by a given spacing wherein the elastic members are secured in a stretched state to the nonwoven fabric sheets. The composite sheet has a plurality of gathers formed by slightly undulated surface of the nonwoven fabric sheets and the elastic members and these gathers are substantially continuous in the longitudinal direction and arranged at substantially regular intervals in the transverse direction.

Stretchable composite sheet and process for forming the same with a plurality of gathers

A disposable diaper is formed in one of front and rear waist regions with first wings which are elastically stretchable in a waist-surrounding direction and these first wings are provided on respective body facing surfaces with first fastener elements. The other waist region is provided on its undergarment facing surface with, in addition to second fastener elements, anti-slip zones exhibiting a desired average kinetic frictional force relative to the body facing surface of the first wings.
