  • Patent number: 5804219
    Abstract: The present invention relates to compositions and processes which incorporate water-soluble polymers, other than enzymes, containing .dbd.N--C(.dbd.O)-- (including PVP) and/or N-oxide groups into the wash, rinse, and/or drying cycle of a laundering process (e.g., via fabric softening compositions) for dye transfer inhibition in the subsequent wash cycle. Multiple wash cycles optimize the dye transfer inhibitor performance of these polymers, remove unwanted dye discoloration caused by dye transfer, and provide soil antiredeposition benefits.

  • Patent number: 5800654
    Abstract: Disclosed is a sanitary napkin having flaps folded over the topsheet. This arrangement helps to maintain the topsheet in a sanitary condition and is more convenient for the wearer than a configuration having the flaps folded over the backsheet. The flaps may be maintained in this folded arrangement by a unitary release strip which bridges the flaps and covers any adhesive used to attach the flaps to the undergarment. If desired, the release paper may further wrap the longitudinal side margins of the sanitary napkin to additionally cover adhesive disposed on the central portion of the backsheet. If desired, the flaps may be folded over the topsheet, overlap each other and be adhesively joined to the other flap.

  • Patent number: 5800416
    Abstract: The fluid absorbent members according to the present invention preferably comprise three basic components: chemically stiffened, twisted, and curled bulking fibers, high surface area fibers, and chemical binder additive. Fluid absorbent members according to the present invention use a high surface fiber and refining to provide capillary pressure (or suction) to the fluid absorbent member. These high surface area fibers are generally small and highly conformable. They provide the substrate with capillary pressure well in excess of the capillary pressure found in the bulk-providing chemically stiffened, twisted, and curled fibers (unrefined) alone. A presently preferred fiber for this high surface application is the eucalyptus family of wood pulp fibers. Eucalyptus provides desirable capillary pressure characteristics in combination with the chemically stiffened, twisted, and curled fibers and will not easily pass through a forming screen.

Preferred antimicrobial compounds made by these processes are those where the beta-lactam moiety is a penem, a carbapenem, a cephem, or a carbacephem. Also preferred are those compounds where L.sup.1, L, and L.sup.
