Absorbent article and surface sheet thereof

摘要

Disclosed is an absorbent article having an absorbent member positioned between a liquid-permeable multilayer surface sheet and a backside sheet. A plastic film layer is laminated on the non-skin contact surface side of the multilayer surface sheet. The multilayer surface sheet has embossments in the form of a large number of elevated portions protruding outward, the elevated portions being formed by heating the sheet to a temperature higher than the melting point of the plastic film layer but lower than the melting point of the nonwoven fabric layer. The multilayer surface sheet is also provided with a large number of openings. The absorbent article has a highly spatial appearance, provides good cushioning effect with minimized skin contact, and retains uneven emboss, even upon absorption of a body fluid.

主权项

1. An absorbent article comprising an absorbent member interposed between a liquid-permeable multilayer surface sheet and a backside sheet, the multilayer surface sheet comprising a nonwoven fabric layer having a skin contact surface side and a non-skin contact surface side and a plastic film layer laminated on the non-skin contact surface side of the nonwoven fabric layer, the plastic film layer comprising a material having a melting point that is lower than a melting point of the nonwoven fabric layer,
the multilayer surface sheet being provided with an uneven surface contour including a plurality of elevated portions protruding outward, the uneven surface contour being formed by embossing the multilayer surface sheet with heating to a temperature that is not lower than a melting point of the plastic film layer and that is lower than a melting point of the nonwoven fabric layer, whereby only the plastic film layer is deformed by the embossing and heating, the uneven surface contour of the multilayer surface sheet being retained after the heating and embossing, the multilayer surface sheet having a plurality of through holes.
