    摘要： Laminated fiber network structures having high resilience, good cushioning properties, and excellent impact-resistance include at least one layer of a three-dimensional fiber network material and a second layer, which may be a planar material (e.g. a fabric, film, or sheet) or a second layer of a three-dimensional fiber network material. The surfaces of the two layers face each other and are bonded together at their points of contact. The three-dimensional fiber network material is a fabric made from thermoplastic filaments that are at least 0.1 mm in diameter, where the fabric has an array of projections and optional depressions pushed out of one or both sides of the fabric.

    摘要： A highly hydrophilic polyurethane article, which is the skeletal network of a cellular polyurethane foam subjected to a reticulation process wherein the polyurethane contains up to 100 parts of a superabsorbent material per hundred parts of polyol used in preparing the polyurethane, is useful in absorbing and holding large amounts of aqueous liquids is prepared by:(a) mixing a polyisocyanate, a polyol and a blowing agent with a finely divided superabsorbent material which is insoluble in a liquid which the material absorbs and which absorbs at least 15 times its weight of said liquid,(b) reacting the polyisocyanate, polyol and blowing agent under foaming conditions to produce a foam of polyurethane which cmprises a multitude of gas cells or bubbles within the polyurethane matrix,(c) curing said foam of polyurethane, forming a cellular structure with windows or membranes of solid polyurethanes present between gas cells or bubbles,(d) removing the windows or membranes by thermal reticulation thereby leaving the skeletal structure of the cured polyurethane; and said article is useful wherever high absorption and retention of large quantities of aqueous liquids is needed, including diapers, surgical sponges, and so forth.

    摘要： Disclosed by this invention are polybenzimidazole polymer/superabsorbent polymer articles. These articles are prepared by either mixing the superabsorbent polymer particulates with the polybenzimidazole polymer solution during the formation of the polybenzimidazole article, or forming a composite of a polybenzimidazole film or fiber material layer with a superabsorbent polymer particulate containing layer. These polybenzimidazole products, either with the superabsorbent polymer particulates interspersed within their structure of as composites, absorb large amounts of fluid while retaining the flame retardancy and chemical unreactivity of conventional polybenzimidazole materials.
