  • Patent number: 4551142
    Abstract: An absorbent material is provided for body fluid absorbent products which material has relatively high tensile strength, and is extremely flexible and may be incorporated into absorbent products without substantial loss in user's comfort. The material is made by forming a slurry of water wherein the solids comprise cellulosic fibers and hydrocolloidal material. The wet web is formed from the slurry and the web is then dried. The dry web is then compacted to a density of at least 110% and preferably at least 150% based on the density of the dry web. The resulting product has a tensile strength of at least 10 Kg/cm.sup.2 and the Gurley Stiffness of less than about 40 gm.
