PROBLEM TO BE SOLVED: To provide a dyeing method for acrylic fiber materials that can shorten the time and reduce the cost for the conventional dyeing process and the production process without adverse effect on the quality and the fabric hand of the acrylic fiber material, particularly can give a favorite color to gigged fiber products having shrinkable acrylic fiber admixed. SOLUTION: After an anionic surfactant is added to acrylic fiber material, the material is treated with a dyeing solution including cationic dye at a temperature of≤70°C. Then, the fiber material is treated with dry heat at≥120°C or with moist heat at≥90°C, while the material is formed to fiber products. COPYRIGHT: (C)2003,JPO
