  • Patent number: 6881876
    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.
