POLYLACTIC ACID FIBER STRUCTURE HAVING EXCELLENT CHROMATIC COLOR DEVELOPMENT AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a polylactic acid fiber structure having excellent chromatic color development and high heat resistance and to provide a method for producing the same. SOLUTION: This polylactic acid fiber structure obtained by using a polylactic acid fiber composed of a blend of a poly(L-lactic acid) and a poly(D- lactic acid) at least as a part is dyed with a chromatic color dye.
