A method for preparing a color masterbatch with a natural dye is disclosed. The new method uses a phase change material tetradecane as one of the solvents to extract the natural dye, the extracted natural dye as a core material, and polybutylene succinate as a wall material to microencapsulate the natural dye containing the phase change material by a solvent evaporation method to prepare natural dye microcapsules, then melt-blends with a carrier resin, extrudes and granulates to obtain the color masterbatch with the natural dye. The microencapsulation improves the thermal stability of natural dye and compatibility with carrier resin The obtained color masterbatch with natural dye has excellent heat resistance, and the fabric obtained after spinning with it has good color fastness to hot pressing.
