Abstract
A topsheet for body fluids absorbent article having a plurality of liquid-pervious apertures, the topsheet including an upper fibrous layer having a relatively low density and a lower fibrous layer having a relatively high density. Around each of the apertures, the first and second fibrous layers are integrated together so that the topsheet has a density progressively increasing from an upper surface towards a lower surface of the topsheet and has, in the proximity of the lower surface, a density further higher than in the second fibrous layer. The topsheet thus formed improves so that an upper surface thereof can be maintained in a dry state during use of the article having the topsheet.
Claims8
A topsheet for a body fluids absorbent article comprising:
- said topsheet having an upper surface intended to be placed against a wearer's skin;
- a lower surface underlying said upper surface;
- a plurality of liquid-pervious apertures extending between said upper and lower surfaces;
- said topsheet having an upper part defined by a first fibrous layer and a lower part defined by a second fibrous layer having a density higher than that of said first fibrous layer, and
- around each of said apertures, said first and second fibrous layers being integrated together so that said topsheet has a density progressively increasing from said upper surface towards said lower surface and, at least in proximity of said lower surface, has a density further higher than the density in said second fibrous flayer.
A topsheet for body fluids absorbent article comprising:
- an upper surface intended to be placed against a wearer's skin;
- a lower surface underlying said upper surface;
- a plurality of liquid-pervious apertures extending between said upper and lower surfaces without protruding from the lower surface;
- said topsheet having an upper part defined by a first fibrous layer and a lower part defined by a second fibrous layer having a density higher than that of said first fibrous layer wherein a lower surface of said first fibrous layer is entirely in close contact with an upper surface of said second fibrous layer, and
- around each of said apertures, said first and second fibrous layers being integrated together so that said topsheet has a density progressively increasing from said upper surface towards said lower surface and, at least in proximity of said lower surface, has a density further higher than in said second fibrous layer.
A topsheet for a body fluids absorbent article consisting essentially of:
- said topsheet having an upper surface intended to be placed against a wearer's skin;
- a lower surface underlying said upper surface;
- a plurality of liquid-pervious apertures extending between said upper and lower surfaces;
- said topsheet having an upper part defined by a first fibrous layer and a lower part defined by a second fibrous layer having a density higher than that of said first fibrous layer, and around each of said apertures, said first and second fibrous layers being integrated together so that said topsheet has a density progressively increasing from said upper surface towards said lower surface and, at least in proximity of said lower surface, has density further higher than the density in said second fibrous layer.
