  • Patent number: 9162007
    Abstract: A superabsorbent polymer composite including superabsorbent polymers and cellulosic nanofibrils having a diameter equal to or less than 100 nm. The composite may be in the form of particles or a foam. Methods for producing the composite and absorbent articles including the superabsorbent polymer composite are also provided.
    Type: Grant

  • Patent number: 8672912
    Abstract: An absorbent article includes a chassis extending about a longitudinal axis and having a topsheet, a backsheet and an absorbent structure disposed between the topsheet and the backsheet. The chassis has a first transverse axis dividing the absorbent structure into a front body panel terminating in a front waist region and a rear body panel terminating in a rear waist region. The rear waist region has a first elastic region. The chassis is delimited by opposed longitudinal edges and opposed transverse edges. In the rear waist region, the absorbent structure terminates at a first distance from the transverse edge and the first elastic region extends substantially parallel to the transverse edge and spaced therefrom by a second distance and spaced from the absorbent structure by a third distance. The third distance is greater than said second distance or substantially equal thereto.

  • Patent number: 8273817
    Abstract: A fiber, film or foam includes a plasticizer and a charged claylinked gel (A). The charged claylinked gel (A) includes clay nanoparticles (C) which are crosslinked by a charged polymer (A?) such that any particular clay nanoparticle is linked to at least one other clay nanoparticle by the charged polymer (A?). Methods for producing the fibers, film and foam are also provided.

  • Publication number: 20100069864
    Abstract: An absorbent article such as a diaper, panty diaper, panty liner, a sanitary napkin, an incontinence device or the like, includes at least a liquid-permeable topsheet made from at least one layer of web, foam or film material and a backsheet made from at least one layer of web, foam or film material, and optionally at least one further layer of web, foam or film material. At least one of the layers includes a coating of a hydrophobic thermoplastic polymer having an irregular surface and shows a contact angle of a sessile water drop of more than 110°. Depending on the location and the arrangement of this highly hydrophobic coating, beneficial effects in terms of the control of body liquids arise.
