  • Patent number: 5994615
    Abstract: There is provided a surge material for personal care products which is a wettable web of fibers of 30 microns in diameter or less where the web has a permeability between about 250 and 1500 Darcys, a capillary tension between about 1.5 and 5 cm, and which maintains that permeability and capillary tension over the life of the web. Its preferred that the web have a density between about 0.02 g/cc to about 0.07 g/cc.
    Type: Grant
    Filed: December 16, 1998
    Date of Patent: November 30, 1999
    Assignee: Kimberly-Clark Worldwide, Inc.

  • Patent number: 5843063
    Abstract: A multifunctional material is provided for use in personal care products. The multifunctional material has a permeability between 100 and 10000 Darcys and a capillary tension between about 2 and 15 cm. Structures containing this multifunctional material can have a runoff rate of less than 25 ml per 100 ml insult, over its life. The multifunctional material should have between about 30 and 75 weight percent of a slow rate superabsorbent, between 25 and 70 weight percent of pulp and from a positive amount up to about 10 percent of a binder component. The material preferably has a density between about 0.05 and 0.5 g/cc. The material has a liquid pass through function which desorbs a surge material across time frames consistent with user conditions and releases the liquid for distribution to remote storage locations. The material, when combined with the intake and distribution materials, defines a composite structure for use in personal care products.

  • Patent number: 5820973
    Abstract: There is provided a surge material for personal care products comprising a layered structure of at least one relatively high permeability layer on a top side toward a wearer and at least one relatively low permeability layer where the structure has a capillary tension range between about 1 and 5 cm with a differential capillary tension of at least about 1 cm from top to bottom. The surge material should have a high permeability layer with a permeability of at least 1000 Darcys and a low permeability layer with a permeability of less than 1000 Darcys. The surge material should also have a said high permeability layer which has a permeability of at least 250 Darcys greater than the low permeability layer. Such a layered structure should have a first insult run-off value of at most 30 ml from a 100 ml insult delivered at 20 ml/second. Such a surge material is useful in personal care products like diapers, training pants, absorbent underpants, adult incontinence products, feminine hygiene products and the like.
