    摘要： Superabsorbent polymer materials are provided including absorbent polymers having a fast vortex time, desirably about 10 seconds or less, and a stiffness index of at least about 0.7, as determined by test procedures described herein. The absorbent polymers can be modified to obtain a faster vortex time by a method including providing an absorbent polymer having a first vortex time, absorbing water with the absorbent polymer, freeze-drying the swollen absorbent polymer to remove at least a portion of the absorbed water, and obtaining a modified absorbent polymer having a second vortex time. The ratio of the first vortex time to the second vortex time is at least about 5, and desirably the modified absorbent polymer has a stiffness index of at least about 0.7.

    摘要： This invention relates to an absorbent composite which utilizes multifunctional superabsorbent materials to enhance distribution of fluids within the absorbent composite. More specifically, this invention relates to superabsorbent materials which swell and absorb fluids and also can deswell and release fluids into the surrounding absorbent composite and towards additional superabsorbent material. The superabsorbent materials of this invention deswell and release fluid by means of a triggering mechanism. Triggering mechanisms can include thermal, chemical, mechanical, electronic, magnetic, and radiation energies. Swelling and deswelling of the superabsorbent materials can be repeated for more than one cycle thereby improving fluid distribution. Multiple swelling and deswelling cycles allow multiple insults to be distributed throughout an absorbent composite, fully utilizing the absorbent capabilities of the full absorbent composite and minimizing leakage.

    摘要： An absorbent fibrous foam composite comprising a fluid intake capacity of at least 15 g/g, a vertical wicking distance of at least 10 cm, and an absorbency under zero load of at least 15 g/g. The absorbent fibrous foam composite comprising a water insoluble fibrous material and a superabsorbent material. The absorbent fibrous foam composite made by forming a slurry of water, a water-insoluble fiber, and a binding agent. A water-swellable, water-insoluble superabsorbent material is added to the slurry and the temperature is lowered until the water freezes. The frozen water is then removed by sublimation process and an absorbent fibrous foam recovered. The Gelation Time, which represents a fluid absorption rate of superabsorbent during the preparation, is critical to preparing uniform absorbent freeze-dried foams and can be adjusted by various mixing conditions and physical and chemical superabsorbent treatments.

    摘要： Fibrous articles are disclosed containing an additive composition. The additive composition, for instance, may include a water-soluble film forming component and water-soluble modifying components that is deposited at least at the surface of a fibrous web. In some aspects, the additive composition includes polymers that demonstrate a certain LCST and melting temperature. In another aspect, the additive composition is applied to the fibrous web during the heated drying phase, such as with a Yankee dryer. The fibrous web with additive composition is then creped. The additive composition may improve the perceived softness of the web without substantially affecting the absorbency of the web in an adverse manner.

    摘要： In a method of making an absorbent composite, a porous, stabilized structure is formed and impregnated with a flowable superabsorbent precursor. The flowable superabsorbent precursor is cross-linked to form a superabsorbent material within the stabilized structure. The surface area of one of the flowable superabsorbent precursor impregnated with the stabilized structure and the superabsorbent material formed within the structure is increased. In one embodiment, the surface is increased by freeze drying the impregnated structure.

    摘要： An article comprises a stretchable absorbent composite (30) that includes a quantity of superabsorbent particles (32) which are operatively contained within a matrix of elastomeric polymer fibers (34). In particular aspects, the composite article can include at least about 60 wt % of the superabsorbent particles and not more than about 40 wt % of the elastomeric polymer fibers, based on a total weight of the composite. In other aspects, the composite article can provide a high stretchability. Additional aspects can provide a low shake-out. Particular configurations can, for example, provide a stretchability value of at least about 30%. Additional aspects can include a configuration that provides a shake-out value of not more than about 2%. In other aspects, the invention can provide a shake-out value of not more than about 1.2%. In further aspects, the absorbent composite can include superabsorbent particles having a coating of treatment-material that is thermally processible.
