    摘要: A microcavity-containing, resilient foam comprising a thermoplastic polymer; composite structures comprising such a microcavity-containing foam and a multiplicity of particles contained in such microcavities, preferably aqueous fluid absorbent particles; methods for preparation of such foam and structures; and disposable consumer articles incorporating such foams and composites. The aqueous fluid absorbent characteristics of the foam and composite structures render them useful in the fabrication of disposable consumer articles, in particular hygiene articles designed to rapidly absorb “insults” of bodily fluid thereby conducting such fluids away from contact with the skin of the wearer of the hygiene article. The useful articles include infant and children diapers, adult incontinence pants, feminine hygiene pads, pet urine-absorbent pads and mats, household cleaning pads, surgical drapery, and the like.

    摘要: A method for generating a thermoplastic foam from an aqueous dispersion, the aqueous dispersion comprising a thermoplastic resin, water, and a dispersion stabilizing agent, the method including: adding at least one froth stabilizing surfactant to the aqueous dispersion to form a mixture; adding a fiber to the mixture; and frothing the mixture to create a froth, removing at least a portion of the water in the froth to create a foam, wherein the foam generated has a non-cellular fibrillated morphology. In another aspect, embodiments disclosed herein relate to a foam having a thermoplastic-based, fibrillated, non-cellular structure, wherein the foam has an average density of about 0.02 g/cm3 to about 0.07 g/cm3. In certain embodiments, the foam may be used in an absorbent article.
