  • Publication number: 20160235601
    Abstract: An extruded water-soluble article includes a water-soluble polymer having an extrusion temperature of 90 to 150 C., a plasticizer, and one or more active agents in a total amount of 0.1% to 50% by weight of the article. Combining the active agent(s) with a plasticizer prior to melt-blending with the water-soluble polymer prevents phase separation of the active agent and the polymer. Articles include films, fibers, rods, bars and the like. Such articles may be placed in an absorbent article such as a bandage, a medical drape, a wipe, a sheet, a diaper, a pant, or a pad.

  • Patent number: 9238348
    Abstract: A laminate of nonwoven materials having fine particulate matter attached thereto is made with a lamination process capable of supplying up to about 60 gsm of particulate matter to a substrate. The particulate matter may be applied to the substrate using a powder coating apparatus. The laminate may be used in personal absorbent articles such as diapers, feminine pads, bandages, bed pads, and the like.

  • Publication number: 20080119586
    Abstract: When a superabsorbent material is to be incorporated into an absorbent composite in a relatively high concentration, it is necessary to carefully choose the superabsorbent material. Properties of the superabsorbent material to be considered are total Absorbent Capacity, resistance to Deformation Under Load, the ability of the superabsorbent material to absorb while under a restraining force, and the ability of the superabsorbent material to wick fluids away from the insult area. By quantifying these characteristics of a superabsorbent material, Applicants are able to predict which superabsorbent materials are suited for use in absorbent composites comprising a relatively high concentration of superabsorbent material.
