  • Absorbent articles with controllable fill patterns
    Patent number: 6465712
    Abstract: There is provided an absorbent system for personal care products which may be transversely divided into about an equally sized center zone, two intermediate zones and two end zones where the ratio of the amount of liquid stored in the center zone to the amount of liquid stored in at least one of the end zones 30 minutes each of three insults of 80 ml according to a MIST Evaluation Test after less than 5:1. Such an absorbent system may be used in personal care products like diapers, training pants, feminine hygiene products, absorbent underpants, adult incontinence products, and the like.

  • Multifunctional absorbent material and products made therefrom
    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.
