The embodiment of the invention discloses a high-color-fastness fiber as well as a preparation method and application thereof. The high-color-fastness fiber is prepared from 70 to 90 parts of PET (Polyethylene Terephthalate) and 1 to 10 parts of modified color master batch. Wherein the modified color master batch comprises first carrier resin and a modified pigment, and the weight ratio of the first carrier resin to the modified pigment is (50-70): (10-30); the modified pigment comprises a pigment and a nucleating agent. The pigment is modified through the nucleating agent, so that the pigment has PET nucleating performance, PET in the high-color-fastness fiber binds the pigment in a crystal region, movement and migration of the pigment are limited, outward migration of the pigment is effectively prevented, and the color fastness of the high-color-fastness fiber is improved. 本申请实施例公开一种高色牢度纤维及其制备方法和应用。该高色牢度纤维包括PET 70-90份，改性色母粒1-10份。其中，改性色母粒包括第一载体树脂和改性颜料，且第一载体树脂与改性颜料的重量比为50-70：10-30；改性颜料包括颜料和成核剂。通过成核剂对颜料进行改性处理，
