    Abstract: An oblong absorbent article that includes a liquid-impermeable bottom sheet, and upper liquid-permeable sheet and an absorbent body disposed between these sheets, and on each side of the longitudinal center line of the upper sheet at least one longitudinal elastic liquid barrier having at least the free edge treated with a non-adhesive sealing medium which partly fills out the pores formed between the free edge and the abutment surface on the wearer, and/or which, when the article is donned, increases, around said abutment surface, the wetting angle of the liquid to the skin. An absorbent article that includes an essentially liquid-impermeable top sheet above an absorbent body enclosed between an upper liquid-permeable sheet and a liquid-impermeable sheet, the top sheet being provided with elastic for shaping the article to the wearer's body and incorporating apertures intended to register with the anus and the urethra orifice of a wearer in use, around which apertures elastically puckered sealing edges are disposed, at least one sealing edge being coated with a sealing medium.

    Abstract: A method of improving in an oblong absorbent article that includes a liquid- impermeable bottom sheet, an upper liquid-permeable sheet and an absorbent body disposed between these sheets, and on each side of the longitudinal center line of the upper sheet at least one longitudinal elastic liquid barrier, the sealing effect afforded against the skin of the wearer by at least one liquid barrier on each side of said centre line by causing the absolute value of the negative product 2.gamma. cos.theta.m/r in this liquid barrier to increase. A method of increasing in an absorbent article that includes an essentially liquid-impermeable top sheet above an absorbent body enclosed between an upper liquid-permeable sheet and a liquid-impermeable sheet, the top sheet being provided with elastic for shaping the article to the wearer's body and incorporating apertures intended to register with the anus and the urethra orifice of a wearer in use, around which apertures elastically puckered sealing edges are disposed, the absolute value of the negative product 2.gamma. cos.theta.m/r for at least one sealing edge. An absorbent article where the absolute value of the product 2.gamma. cos.theta.m/r for at least one liquid barrier on each side of the centre lin e of the absorbent body or for at least one sealing barrier lies above the line y=kx+ m, where x designates the available elongation, k has the value -14/30 and m has the value 48 within the major part of an available elongati on range of between 20 and 40 %.

    Abstract: The invention relates to a material structure for use in absorbent articles, and an absorbent article comprising such a material structure. The material structure ( 1 ) comprises a liquid-pervious cover layer ( 2 ), a liquid-impervious cover layer ( 3 ), and an absorbent structure ( 4, 4' ) enclosed between the cover layers ( 2, 3 ). Thereby, the absorbent structure ( 4, 4' ) comprises polylactide fibres or filaments, the properties of which contributing to a rapid acquisition of liquid through the liquid-pervious cover layer ( 2 ) for absorption into the absorbent structure ( 4, 4' ) also when the material structure ( 1 ) is subjected to repeated wettings. The invention can advantageously be applied within the field of absorbent hygiene articles, such as different types of diapers and incontinence guards, sanitary napkins, pantyliners, and the like.

    Abstract: A method of improving the sealing effect against the skin of an absorbent article comprising an absorbent body disposed between liquid impermeable and liquid permeable sheets, such article having either longitudinally extending liquid barriers 28 on each side of the centre line of the permeable top sheet which have free elastic edges for contacting the skin or having a further liquid impermeable, body-contacting sheet with anal and urethral apertures around which elastic sealing edges are provided, comprises increasing the capillary pressure of the pores of said barriers/sealing edges by causing the absolute value of the negative product 2γcos#m/r to increase. This is achieved by decreasing the pore radius r and/or by increasing the wetting angle #, γ being the surface tension of the liquid to be absorbed and cos#m being the weighted mean value of cos#. A diaper or incontinence guard having such improved properties is thereby provided.
