IRRADIATION AND WATER TREATMENT OF FIBROUS MATERIAL AFTER ACRYLATE IMPREGNATION AND IRRADIATION

摘要

An improvement in a process for producing an absorbent composite wherein a solution of acrylic or methacrylic acid salts is applied to a substrate and the impregnated substrate is irradiated to form a water swellable polymer in-situ within such substrate. The improvement comprises saturating the irradiated substrate with an aqueous liquid and then drying to a moisture content of less than 20 per cent by weight whereby the dried substrate exhibits rapid absorption properties.
