NOVELTY - Colored polylactic acid tow comprises material A and material B. The material A includes 45-70 wt.% crystalline polylactic acid, and 0.02-0.2 wt.% nucleating agent. The material B includes 26-45 wt.% amorphous polylactic acid, 3.75-9.88 wt.% color fixing material, 0.05-0.1 wt.% pigment. USE - Colored polylactic acid tow. ADVANTAGE - The colored polylactic acid tow has good heat resistance, excellent coloring performance and color retention. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing colored polylactic acid tow, which involves taking materials according to the raw material ratio to prepare polylactic acid nascent tow, drawing nascent tow obtained to obtain colored polylactic acid tow.
