The invention relates to the technical field of D06P5/08, in particular to an acidic color fixing agent as well as a preparation method and an application method thereof. The acidic color fixing agent is prepared from the following raw materials in parts by weight: 30-45 parts of phenolic resin, 15-25 parts of acetic acid, 10-25 parts of a sulfonating agent, 1-3 parts of a reducing agent and 20-30 parts of deionized water. According to the acid color fixing agent, the utilization rate of a dye can be remarkably increased, the color fastness of the acid dye and the product quality are improved, the color fixing agent does not change color, the color fixing effect is effectively improved, the production cost is reduced, meanwhile, wastewater discharge is reduced, meanwhile, the color change of a fabric subjected to color fixing through the acid color fixing agent is small, and the original style of the fabric is not affected. 本发明涉及D06P5/08技术领域，更具体涉及一种酸性固色剂、制备方法及其应用方法。酸性固色剂，按重量份计，制备原料包括30-45份酚醛树脂、15-25份醋酸、10-25份
