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.

Abstract: The present invention provides processes for making compounds of the structure(Q--L.sup.1)--L--(L.sup.2 --B)wherein(I) Q is a quinolone moiety;(II) B is a lactam moiety; and(III) L, L.sup.1, and L.sup.2 together comprise a linking moiety;comprising the steps of:(1) coupling a compound of Formula (III) with a lactam-containing compound to form an intermediate compound; and(2) cyclizing the intermediate by reaction with an organosilicon compound to give a compound of the formula (Q--L.sup.1)--L--(L.sup.2 --B).Preferably, the process additionally comprises a step prior to the coupling step, wherein protected forms of the compound of Formula (III) and the lactam compound are formed; and deprotection steps after the cyclization step, wherein the protecting groups are removed. 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.

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.

Abstract: An insertion device 10 for inserting material 13 into a body cavity is provided. An elongate, tubular holder 12, shaped for insertion into the body cavity, is adapted to hold the material to be inserted. The holder 12 has a material expulsion end portion 14 and a plunger 20, which is telescopically and slidably mounted in the holder, which is adapted to expel the material from the holder when pushed manually into the holder. The holder, and preferably the plunger as well, comprises an outer paper layer 28 and a polymer layer 30, adhered to the paper layer on its outer surface, the layer having adequate water resistance to maintain its integrity during insertion into the body cavity.

Abstract: Absorbent composites containing particles of absorbent gelling material and chemically stiffened, cellulosic fibers, the fibers being wrapped around and adhered to the particles, which are in individual form. The chemically stiffened, cellulosic fibers are preferably cellulosic fibers in substantially individual form having a crosslinking agent reacted with the fibers in intrafiber crosslink bond form. The absorbent composites are particularly suitable for use in the absorbent core of disposable absorbent articles such as sanitary napkins and diapers.
Abstract: The present invention relates to a wrinkle reducing composition for use on fabrics, particularly clothing. The composition comprises a wrinkle reducing active, which is made up of an effective amount of silicone and an effective amount of film-forming polymer, and a liquid carrier. The composition is substantially free of starch, modified starch, and mixtures thereof, and results a Loss Modulus Difference of greater than about 3.3.times.10.sup.7 Pascal on fabric. The composition can be incorporated into a spray dispenser that can create an article of manufacture which facilitates treatment of the fabric with the wrinkle reducing composition. The wrinkle reducing actives in the composition can be determined through Dynamic Mechanical Analysis using a 100% cotton broadcloth swatch and a fixed volume of a sample of wrinkle reducing active.

Abstract: A disposable absorbent article such as a diaper. The diaper has a topsheet, backsheet, and an intermediate core. Affixed to the outwardly oriented surface of the topsheet is an expulsive spacer. The spacer receives and collects fecal material from the wearer. The spacer may be removable from the diaper, or may be articulable relative to the diaper. By expelling the spacer from the diaper, fecal material can be easily flushed into the toilet, rather than discarded into a waste receptacle where it presents a sanitation hazard.

Abstract: The present invention provides method for making a wet pressed paper web. An embryonic web of papermaking fibers is formed on a foraminous forming member, and transferred to an imprinting member to deflect a portion of the papermaking fibers in the embryonic web into deflection conduits in the imprinting member. The web and the imprinting member are then pressed between first and second dewatering felts in a compression nip to further deflect the papermaking fibers into the deflection conduits in the imprinting member and to remove water from both sides of the web. The compression nip has an extended length, and can comprise convex and concave opposed compression surfaces.

Abstract: This invention relates to a process for forming a single-layer, durably wettable polymeric web having a plurality of apertures. This process comprises melting a mixture of at least one thermoplastic polymer and at least one migratable surfactant and extruding the mixture to form a single-layer, substantially continuous polymeric film. The film is then apertured using high pressure fluid flows. Aperture formation is conducted when the single-layer polymeric film has a contact angle of at least about 30.degree., to minimize wash-off of the surfactant impregnated in the polymer web. The invention also relates to durably-wettable apertured webs.
