  • Patent number: 7838723
    Abstract: The invention relates to absorbent structures for use in absorbent articles. The structures include a first region for distribution of fluid and a second region for storage of fluid. The first region contains materials, with a relatively high capillary desorption pressure, while the second region contains materials exhibiting a sufficiently high capillary absorption pressure efficiently drain the first region. Exemplary materials have a CSDH 50 of more than 40 cm, and a second region containing a material which satisfies at least one of following requirements: (a) an absorption capacity of at least 15 g/g at 35 cm (b) an absorption capacity of at least 15 g/g at 0 cm and an absorption efficiency of at least 55% at 40 cm; and (c) a Capillary Sorption Absorption height at 50% of its capacity at 0 cm absorption height (CSAH 50) of at least 35 cm.

  • Patent number: 7794839
    Abstract: This invention is directed to coated water-swellable materials, typically solid, particulate, water-swellable materials, i.e. materials that comprise hydrogel-forming polymers, whereof at least a part is coated with a coating, which substantially does not break when the polymers swell, as set out in the method herein. Said coating is present at a level of at least 1% by weight of the water-swellable material. The coating comprises preferably an elastomeric polymeric material. The invention also relates products, e.g., disposable absorbent articles, comprising such coated water-swellable material.

  • Patent number: 7794440
    Abstract: The present invention relates to a disposable absorbent article, such as a diaper, training pants, adult incontinence article, having a specific topsheet with an opening to receive bowel movement waste (BM) and which is such that it masks the waste present underneath said topsheet. The topsheet is air permeable and it has a uniform pore size distribution with small pores only and it has a low surface energy and therefore an alcohol repellency of at least 7, typically at least 9 or even preferably 10.

  • Patent number: 7700153
    Abstract: This invention is directed to a process for making solid, typically particulate, water-swellable material comprising coated water-swellable, preferably hydrogel-forming polymers, which are coated with a coating agent, which is such that it does not rupture when the polymers swell in a liquid, e.g., water or saline water. Hereto, the coating agent is extensible in wet state and comprises thereto a wet-extensible material that has a wet-elongation of at least 400%, or even more preferably at least 500%, and preferably a tensile stress at break in the wet state of at least 1 MPa. Typically, the coating agent comprises thereto an elastomeric polymeric material. The invention also relates to solid (particulate) water-swellable material obtainable by the process of the invention.
