POLYLACTIC ACID FIBER HAVING 31 SPIRAL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To obtain a nonconventional polylactic acid fiber exhibiting excellent high-temperature mechanical properties. SOLUTION: The polylactic acid fiber comprises a poly(L-lactic acid) or poly(D-lactic acid) molecular chain singly forming 31spiral structure and has≤2% Uster irregularity. COPYRIGHT: (C)2004,JPO
