PROBLEM TO BE SOLVED: To save the amount of an enzyme used and uniformly, continuously and enzymically treat a textile material without unevenness by alternately repeating an enzymic adsorbing step and an enzymic desorbing step for the textile material. SOLUTION: An enzymic adsorbing step and an enzymic desorbing step for carrying out the dipping treatment of a textile material such as a cellulosic fiber, silk, promix and a mixed spun fiber, a twisted union yarn and a union cloth product, etc., thereof with a synthetic fiber in a treating liquid containing a prescribed enzyme such as a cellulolytic, a pectolytic, a lipolytic or a proteolytic enzyme, squeezing the liquid and heat-treating the textile material are alternately repeated to continuously perform the enzymic treatment when carrying out the weight reduction processing, scouring treatment, etc., of the textile material with the enzyme.
