  • Patent number: 5593399
    Abstract: An absorbent article comprises a first, liquid-permeable carrier layer and at least a second carrier layer. A carrier attaching mechanism secures together the carrier layers to provide substantially attached zones and a multiplicity of substantially unattached zones thereof. The substantially unattached zones provide a plurality of pocket regions, and high-absorbency material is located within the pocket regions to provide an absorbent laminate having a laminate length and a laminate width. A selected plurality of the pocket regions can, for example, be configured with an elongate shape having a major axis length and a relatively shorter minor axis width. The selected plurality of elongate pocket regions is included within a dispersed pocket array having a non-contiguous, labyrinth configuration of pockets.

  • Patent number: 5552020
    Abstract: Tissue products having improved bulk and softness are made by adding one or more softeners/debonders and a silicone glycol copolymer of the papermaking fibers at the wet end of the tissue machine, prior to the formation of the tissue web. Suitable softeners/debonders include organoreactive polysiloxanes, quaternary ammonium compounds, quaternized protein compounds, phospholipids, and silicone quaternaries.

  • Patent number: 5550189
    Abstract: Disclosed is a method for producing a water-swellable, generally water-insoluble modified polysaccharide having improved age-stable absorption properties. The method involves forming a mixture of a modified polysaccharide, water, and, optionally, a crosslinking agent, recovering the modified polysaccharide from the mixture and, optionally, heat-treating said recovered modified polysaccharide.

  • Patent number: 5433715
    Abstract: An absorbent article comprises a first, liquid-permeable carrier layer and at least a second carrier layer. A water sensitive attaching mechanism secures together the carrier layers to provide substantially attached zones and substantially unattached zones thereof. The substantially unattached zones provide a plurality of pocket regions, and a high absorbency material is located within the pocket regions to provide an absorbent laminate. A secondary attaching mechanism secures together the carrier layers along selected secondary attachment regions and provides a substantially water-insensitive connection therebetween. The secondary attachment regions are substantially restricted to locations spaced from the pocket regions.

  • Patent number: 5425725
    Abstract: An absorbent article comprises a first, liquid-permeable carrier layer and at least a second carrier layer. A carrier attaching mechanism, such as a water-sensitive adhesive, secures together the carrier layers to provide substantially attached zones and a multiplicity of substantially unattached zones thereof. The substantially unattached zones provide a plurality of pocket regions, and a high-absorbency material is located within the pocket regions to provide an absorbent laminate. Matrix fibers are dispersed within the high-absorbency material in the pocket regions, and the matrix fibers are present in a selected amount which, in particular aspects of the invention, can be within the range of about 0.1-10 weight percent, as determined with respect to the total weight of the absorbent material contained in the pockets.
