  • Patent number: 7642398
    Abstract: An elasticized web has a gatherable substrate and a multi-strand elastic yarn affixed to the gatherable substrate at a plurality of fixation locations. So that the yarn can be affixed to the substrate without the use of an adhesive, the yarn is subjected to forces to create partial delamination of the yarn at the fixation locations and a portion of the gatherable substrate is caused to pass between the thus delaminated strands of the multi-strand elastic yarn. The elasticized web of the present invention is particularly suitable for use in disposable absorbent articles.

  • Patent number: 7598427
    Abstract: The invention relates to an absorbent article for taking up body fluids, with a longitudinal direction, a transverse direction, a crotch portion (8) and two end portions (6, 7), and having side edges (9, 10) extending in the longitudinal direction and end edges (11, 12) extending in the transverse direction, and comprising a liquid-permeable cover sheet (2) and a liquid-tight cover sheet (3), and an absorbent body (4) arranged between the cover sheets (2, 3), and further comprising barriers which are arranged along the side edges (9, 10) of the article and which are raised up from the liquid-permeable cover sheet (2). The liquid-permeable cover sheet (2) has a central zone (30) which is arranged essentially in the crotch portion (8) of the article, and two end zones (31, 32) which are arranged at the end portions (6, 7) of the article, the liquid-permeable cover sheet (2) being more hydrophilic in the central zone (30) than in the end zones (31, 32).
