Abstract
The present invention is concerned with a high water-absorbent resin composition, produced by forming a composite by fusing or fixing a thermoplastic resin onto a surface of a high water-absorbent resin via an adhesive binder or directly, wherein the composition comprises from 1 to 100 parts by weight of the thermoplastic resin, based on 100 parts by weight of the high water-absorbent resin. When the high water-absorbent resin composition of the present invention is used, it is possible to securely adhere a high water-absorbent resin to a fibrous base material, so that a water-absorbent material which stably retains the high water-absorbent resin even after absorbing water can be obtained. Accordingly, the base materials, such as fibrous base materials, can retain more amount of high water-absorbent resin than those of conventional water-absorbent materials. Thus, it is possible to provide water-absorbent composites suitable for various applications, including hygienic materials, such as paper diapers and sanitary napkins, and agricultural, horticultural, food, and other industrial materials.
