PURPOSE:To manufacture liquid-absorptive composite easily by mixing water- absorptive polymer, water-insoluble inorganic material and water-insoluble hydrophilic fibrous material and drying the mixture if necessary. CONSTITUTION:Water is added to water-absorptive polymer, which substantially absorbs water at about 20cc/g polymer or more, of a polymer or a crosslinked substance of a water-absorptive ethylenic unsaturated monomer consisting mainly of acrylic acid or acrylate at a ratio of 70-3,000pts.wt. of water based on 100pts.wt. of water absorptive polymer, and thus realizing the swelling. Next, water-insoluble inorganic material such as alumina and water-insoluble hydrophilic fibrous material such as natural cellulose are mixed at a ratio of 5-1,200pts.wt. of water-insoluble inorganic material and 5-1,200pts.wt. of water-insoluble hydrophilic fibrous material respectively based on 100pts.wt. of water-absorptive polymer, and are dried if necessary. Consequently, liquid- absorptive composite which demonstrate superior absorptive performance for both low-viscosity and high-viscosity liquids.
