The invention belongs to the technical field of textile waterless dyeing and specifically discloses a textile dye as well as a preparation method and a waterless dyeing method of the textile dye. Thetextile dye is mainly prepared from the following components in parts by weight: 1-10 parts of toner, 3-30 parts of organic solvent, 3-5 parts of triethylene glycol, 2-4 parts of glycerin, 0.5-5 partsof sodium lignin sulfonate, 2-5 parts of sodium metanitrobenzene sulfonate, 1-10 parts of ammonium polyacryloyldimethyl taurate, 1-10 parts of triethanolamine alginate, 0.01-0.5 part of sodium bicarbonate, 1-2 parts of hexadecylpyridinium chloride, 0.5-1 part of coco-dimethylammonium diethyl sulfate and 50-90 parts of deionized water. According to the dye prepared by the invention and the waterless dyeing method, the dyeing effect is good; moreover, washing is not needed, thus any wastewater is not generated, environmental protection is facilitated, and the production cost is lowered.
