Abstract: A wearable article equipped with a multi-level alert system detects and emits signals corresponding to various abnormal levels of a substance in a mammalian extract. By providing different signals corresponding to multiple abnormal levels of the substance, the wearer is simultaneously alerted to the existence of an abnormality, and informed of the level of severity.

Abstract: This invention is a surge material having permanent storage properties that results in faster intake and greater saturation capacity and reduced fluid flowback. More specifically the invention is a surge material with a superabsorbent material printed on in a pattern of discrete regions. The objective of the invention is obtained by printing, or other known application process, a liquid superabsorbent precursor solution containing a crosslinkable composition onto a surge material and then curing the printed surge material to crosslink the polymers to get a surge material having discrete regions of superabsorbent material in the surge material. This invention is also useful in making an absorbent core of an absorbent article with improved strength, increased absorbency, and decreased shedding of superabsorbent material.

Abstract: Absorbent structures having controlled liquid intake, distribution and absorption properties include at least one substrate layer and a flexible absorbent binder formed on and bound to the substrate at selected locations. The flexible absorbent binder is selectively formed so as to provide flow channels, regions of higher and lower fluid intake and absorption, dams for preventing fluid leakage, and other desirable features. The absorbent structures are useful in personal care absorbent articles such as sanitary napkins, diapers, training pants, adult incontinence garments and the like.

Abstract: The present invention discloses water-soluble compositions comprising a blend of poly(ethylene oxide) and poly(vinyl alcohol) that have improved ductility over water-soluble compositions comprising poly(vinyl alcohol) alone.

Grafted poly(ethylene oxide) resins have improved processability and improved blend compatibility with poly(vinyl alcohol). Films comprising a melt blend of poly(vinyl alcohol) and grafted poly(ethylene oxide) have improved melt processability as well as other improved properties. Films comprising compositions of the present invention have improved ductility over films comprising poly(vinyl alcohol) alone while retaining much of the high strength and water solubility exhibited by such poly(vinyl alcohol) films.

Abstract: A superabsorbent composition comprising a superabsorbent material and an elastomer. The superabsorbent composition has a two-phase morphology resulting in one of the superabsorbent material and elastomer being dispersed as aggregates in the other continuous material. The superabsorbent composition has a low glass transition temperature. The low glass transition temperature gives the superabsorbent composition many beneficial properties. This invention also discloses novel superabsorbent particles, fibers, films, and microporous films. Also disclosed in this invention are personal care articles comprising such particles, fibers, films and microporous films.

Abstract: A heterogeneous absorbent core for use in absorbent articles includes a first zone optimized for absorbency of urine and a second zone optimized for absorbency of fecal fluids. The first zone is closer to the front of the core in the article, and includes a first superabsorbent material having a saline absorbency under load of at least about 20 grams/gram. The second zone is closer to the back of the core in the absorbent article, and includes a second superabsorbent material having a fecal fluid absorbency under load of at least about 15 grams/gram. A diaper, training pant, swim wear article and adult incontinence garment which incorporates the heterogeneous core are also provided.

Abstract: A wearable article, such as an absorbent pant product, including a humidity monitoring system. A humidity sensor may be attached to a signal device that produces a signal when relative humidity inside the wearable article reaches a set level, such as 80%. A delivery device may also be connected to the humidity sensor, and may deliver a treatment to a wearer's skin when the relative humidity inside the absorbent article reaches the set level. The humidity monitoring system may be electromechanical, with the opening and closing of an electrical circuit being dependent on the level of relative humidity within the absorbent article.

Abstract: A method for making modified poly(ethylene oxide) by graft polymerizing thereto organic monomers containing a trialkoxy silane functional group or a moiety that reacts with water to form a silanol group, such as methacryloxypropyl trimethoxy silane, onto the poly(ethylene oxide) is disclosed. The graft polymerization is accomplished by mixing the poly(ethylene oxide), the silane-containing monomer(s) and an initiator and applying heat. Preferably, the method is a reactive-extrusion process. After graft polymerization, the modified poly(ethylene oxide) may be exposed or subjected to relatively high moisture conditions, thereby causing crosslinking and formation of a structure that is capable of absorbing relatively large amounts of saline. The resulting modified poly(ethylene oxide) has improved properties over articles similarly processed from unmodified poly(ethylene oxide).
