  • 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.

  • Publication number: 20030100873
    Abstract: A disposable absorbent pant diaper with a longitudinal direction and a transverse direction, an inner cover layer (11), an outer cover layer (12), and an absorption body (10) enclosed between the two cover layers (11, 12), and having two end edges (6, 7) extending in the transverse direction forming a waist opening and two side edges (8, 9) extending in the longitudinal direction forming leg openings, the pant diaper also having a front portion (1) and a rear portion (2) which are connected by an intermediate crotch portion (3). The absorption body (10) is constructed so that the liquid-spreading in the pant diaper is limited to remain below an area of spread of 200 square centimetres in the plane of the absorption body (10) for a liquid quantity of 150 millilitres.

  • Patent number: 6557398
    Abstract: A method of measuring the liquid retention of absorbent articles (20) of the kind that includes an absorbent body having a top side which lies proximal to the wearer's skin when the article is worn, and a bottom side which is covered by a liquid-impermeable backing sheet, wherein the method comprises the steps of applying a determined amount of liquid to a region on the top side of the article, urging a pressure body (1) against a region of the top side of the article with a given force, and collecting and measuring the amount of liquid pressed out from the top side of the article. The force with which the pressure body (1) is pressed against the top side of the article, is set selectively on a device (2-4) for pressing the pressure body against the top side of the article (20), and the liquid pressed from the top side of the article is transported to a measuring vessel (15) with the aid of sub-pressure.
