WET TYPE SPINNING POLYLACTIC ACID FIBER AND PRODUCTION METHOD OF THE SAME

PROBLEM TO BE SOLVED: To provide a polylactic acid fiber that has sufficient strength (elastic modulus or the like) even using wet type spinning (especially electrospinning) in which only a polylactic acid fiber generally having low strength is obtained.SOLUTION: A wet type spinning polylactic acid...

Summary:PROBLEM TO BE SOLVED: To provide a polylactic acid fiber that has sufficient strength (elastic modulus or the like) even using wet type spinning (especially electrospinning) in which only a polylactic acid fiber generally having low strength is obtained.SOLUTION: A wet type spinning polylactic acid fiber has a crystal structure. The wet type spinning polylactic acid fiber is obtained by a production method including a step in which wet type spinning is performed using a polylactic acid solution containing a crystal nucleus agent for example.
