Abstract: Hydrogel composites are provided having improved fluid absorption efficiencies which render them especially useful in disposable absorbent articles, such as diapers, catamenial devices and the like. The hydrogels are in particulate form, each particle or agglomerate of particles being substantially coated with fibers, a portion of which fibers extend from the particle. The fibers enhance the rate at which the hydrogel absorbs aqueous fluids and also serve to maintain the fluid in close proximity to the hydrogel. The extended fibers serve to anchor the hydrogel particle when it is contained in a fibrous or cellular matrix.

Abstract: Particulate, Free-Flowing, Insoluble Swellable Polymers are provided which are comprised of a mixture of an insoluble, swellable hydrogel and inert filler. The mixtures are freeflowing powders or granules which can absorb many times their weight of water and hence are useful as a soil amendment.

Abstract translation: 提供颗粒状，自由流动的不溶性可溶胀聚合物，其由不溶性，可溶胀水凝胶和惰性填料的混合物组成。 混合物是自由流动的粉末或颗粒，其可以吸收其重量的许多倍，因此可用作土壤修饰物。
