  • Patent number: 4921743
    Abstract: A method of evaporative cooling using sorbent sheet materials comprising a fibrous web that includes entangled fibers and a solid high sorbency liquid-sorbent polymeric material is disclosed. A sorbent sheet material useful for administering cold water therapy is also described.
    Type: Grant
    Filed: July 31, 1989
    Date of Patent: May 1, 1990
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Paul E. Hansen, Thomas I. Insley, Christopher J. Libbey
  • Patent number: 4921645
    Abstract: Microfiber microwebs are provided. The microfiber microwebs have relatively dense nuclei with individual fibers and/or fiber bundles protruding therefrom. The microfiber microwebs can be incorporated into nonwoven webs of blown microfibers, air-laid staple fibers, or wood pulp fibers as well as into shaped articles having porous covering materials. The microfiber microwebs are useful in sorbent, filtration, and thermal insulation materials. The microfiber microwebs are prepared by divellicating a microfiber web to form discrete particles of microfiber microwebs.

  • Patent number: 4884684
    Abstract: A containment device for sealing and protecting containers of biological materials. The device comprises a resilient cushion of aqueous fluid sorbent material having a plurality of openings. Each opening is adapted for receiving a respective container of biological material, and the openings are arranged such that each opening is surrounded by sufficient sorbent material to sorb leakage of biological material from its respective container if the container and/or if any additional containers break. The device also includes a case of aqueous fluid resistant material for receiving and enveloping the fluid sorbent material. The case includes two generally stiff-flexible portions having parts adapted for complementary interengagement and adapted to receive means for sealing the portions together to form an air and fluid tight package.

  • Patent number: 4773903
    Abstract: The present invention relates to composite absorbent structures suitable for incorporation into absorbent articles such as sanitary napkins, diapers, training pants and the like. Such structures comprise webs of entangled blown microfibers, substantially non-absorbent crimped staple fibers, particles of certain types of hydrogel-forming polymeric gelling agents and hydrophilizing agent. Such composite web structures of this construction have especially desirable comfort, integrity and absorbency characteristics.

  • Patent number: 4755178
    Abstract: Sorbent sheet products are prepared comprising a coherent fibrous web that includes entangled blown fibers and liquid transport fibers intermingled with the blown fibers and an array of solid high sorbency liquid-sorbent polymeric particles uniformly dispersed and physically held within the web. The particles swell upon sorption of liquid, and the transport fibers cause increased and more rapid sorption of liquid by conducting the liquid from external portions of the web to internal portions of the web.

    Inventors: Thomas I. Insley, Daniel E. Meyer
  • Patent number: 4650479
    Abstract: A sorbent sheet product, particularly useful for disposal diapers, incontinent devices, and sanitary napkins, is provided. The sorbent sheet product comprises a coherent fibrous web that includes entangled blown polymeric fibers and high sorbency, liquid sorbent fibers intermingled with the blown polymeric fibers. The sorbent sheet product may also contain liquid transport fibers.

  • Patent number: 4609584
    Abstract: A microporous liquid impermeable but vapor permeable sheet material useful as a backsheet for disposable absorptive devices such as disposable diapers, incontinent devices, sanitary napkins, and panty liners is disclosed. This backsheet provides unexpected useful attributes such as compatibility with available closure tapes and embossibility with translucent patterns.
