<P>PROBLEM TO BE SOLVED: To provide a polylactic acid-based nonwoven fabric which comprises continuous fibers and is obtained with excellent spinnability and openability, and which can sufficiently retain hydrolysis resistance and strength after a certain period of time has passed, thereby being applicable to practical use. <P>SOLUTION: In the polylactic acid-based nonwoven fabric comprising continuous fibers, the continuous fibers have a core-sheath conjugate form, in which a core part comprises a polylactic acid-based polymer containing a carbodiimide compound and hydrotalcite, and a sheath part comprises a thermoplastic polymer containing no carbodiimide compound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
