Abstract
A far infrared ray emitting, odor-absorbing material is disclosed. The material comprises cellulose acetate fiber having adhered thereto an ultrafine powder of alumina hydrate or silica hydrate which is chemically produced in an aqueous dispersion of the cellulose acetate fiber. The material possesses a high far infrared ray emitting, odor-absorbing capability as well as many characteristics inherently possessed by cellulose acetate fibers, and can expand the utility of cellulose acetate in such fields as sanitary, health-care, and medical fields.
