Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a high quality polylactic acid staple fiber excellent in wearing resistance and hydrolysis resistance. SOLUTION: The polylactic acid staple fibers contains a fatty acid bisamide and/or alkyl substituted monoamide in an amount of 0.1 to 1.5 wt.%, wherein carboxyl terminals are blocked by a carbodiimide compound and the presence ratio of devitrified fibers is 0 to 10%. Further, the method for making the same is also disclosed. COPYRIGHT: (C)2009,JPO&INPIT
