The invention discloses a method for enhancing alkali resistance and oxidation resistance of benzoisothiazole disperse dyes, and belongs to the technical field of textiles. The method starts from thestructural design of the dye; an azo alkali-resistant disperse dye taking the benzoisothiazole as a diazo component is synthesized; different groups are introduced into the coupling component to enhance the alkali resistance and oxygen bleaching resistance of the heterocyclic azo disperse dye, so that a series of benzoisothiazole disperse dyes with alkali resistance and oxidation resistance strength difference gradients are obtained; the disperse dye capable of meeting the requirements of a polyester-cotton blended fabric bleached cotton and disperse dyeing polyester one-bath process or a polyester fabric alkali deweighting and disperse dyeing one-bath process is determined, and a reference can be provided for the structural design of alkali-resistant and oxidation-resistant disperse dyes.
