Abstract
An absorbent article such as a diaper, panty diaper, panty liner, a sanitary napkin, an incontinence protection or the like, having in this order a liquid-permeable coversheet, optionally at least one further layer of a web or foam material, optionally an absorbent layer, and a liquid-impermeable coversheet, characterized in that at least one part of this absorbent article has a polymer that is hydrophilic when dry, but shows a reduced hydrophilicity upon wetting; and to the corresponding liquid-permeable or -impermeable coversheet and web or foam material.
Claims20
An absorbent article comprising in this order
- a liquid-permeable coversheet, and
- a liquid-impermeable coversheet,
- wherein at least one part of the absorbent article comprises a coating comprising a contraphilic polymer that is hydrophilic when dry, but shows a reduced hydrophilicity upon wetting, and
- wherein the coating comprises fine particles and the surface roughness of the coating is increased by the fine particles.
A liquid-permeable coversheet for an absorbent article wherein the liquid-permeable cover-sheet comprises a coating comprising a contraphilic polymer that is hydrophilic when dry, but shows a reduced hydrophilicity upon wetting, and wherein the coating comprises fine particles and the surface roughness of the coating is increased by the fine particles.
A web or foam material for a diaper, a panty diaper, a panty liner, a sanitary napkin, or an incontinence device, wherein the web or foam material comprises a coating comprising a contraphilic polymer that is hydrophilic when dry, but shows a reduced hydrophilicity upon wetting, and wherein the coating comprises fine particles and the surface roughness of the coating is increased by the fine particles.
A liquid-impermeable coversheet for an absorbent article wherein the liquid-impermeable cover-sheet comprises a coating comprising a contraphilic polymer that is hydrophilic when dry, but shows a reduced hydrophilicity upon wetting, and wherein said coating comprises fine particles and the surface roughness of said coating is increased by the fine particles.
