ABSORBENT MATERIAL, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a rapid-absorption absorbent material and a method for manufacturing the material by using an alkylcellulose derivative.

SOLUTION: The method for manufacturing the absorbent material includes: a step in which a cellulose hydrogel is prepared by irradiating a first mixture comprising an alkylcellulose derivative and water with radiation; a step in which a second mixture is prepared by mixing the cellulose hydrogel with hydrophilic fibers while cutting the cellulose hydrogel; and a step in which the second mixture is dried at ≤100°C. The absorbent material contains cellulose hydrogel particles prepared by crosslinking the alkylcellulose derivative, and hydrophilic fibers that reach the inside of the cellulose hydrogel particles from the outside of the particles.
