Beschreibung
Zusammenfassung:	There is provided a new structural composite comprising a web of Z-directionally oriented fibers. The web must contain a large percentage of superabsorbent fibers and the balance of the fibers may be synthetic or natural fibers. Binder fibers are present and should be present in an amount of between 10 and 45 weight percent, more particularly about 30 weight percent. Polyethylene/ polypropylene side-by-side or sheath/core bicomponent fibers are particularly well suited for this purpose. Natural fibers or synthetic fibers that are hydrophilic may also be added to the web in order to control the wettability of the web. Pulp, cotton, and Rayon are suitable for this purpose and may be present in an amount between 0 and 40 weight percent, more particularly about 20 to 30 percent. These materials are suitable for use in personal care products like diapers, training pants, incontinence products, bandages, and sanitary napkins. Se proporciona un nuevo compuesto estructural que comprende un tejido de fibras orientadas en la direccion-z. El tejido debe contener un porcentaje grande de fibras superabsorbentes y el resto de las fibras pueden ser fibras sinteticas o naturales. Las fibras aglutinantes estan presentes y deben estar presentes en una cantidad de entre 10 y 45 % por peso, mas particularmente alrededor de 30% por peso. Las fibras de bicomponente de vaina/nucleo o de lado por lado de polietileno/polipropileno son particularmente muy adecuadas para este proposito. Las fibras naturales o las fibras sinteticas que son hidrofilicas pueden tambien ser agregadas al tejido a fin de controlar el humedecimiento del tejido. La pulpa, el algodon y el rayon son adecuados para este proposito y pueden estar presentes en una cantidad de entre 0 y 40% por peso, mas particularmente alrededor de 20 a 30%. Estos materiales son adecuados para usarse en productos para el cuidado personal como panales, calzoncillos de aprendizaje, productos para la incontinencia, vendajes y toallas sanitarias.
