Polylactic acid particles and manufacturing method therefor
The present invention provides polylactic acid particles, which are formed in a continuous matrix phase from a polylactic acid resin and have a particle diameter of 1 to 100 μm. In a differential scanning calorimetry (DSC) curve of the polylactic acid particles, derived from the analysis by DSC using a temperature rise of 10° C./min, a peak of the cold crystallization temperature (Tcc) is shown at a temperature between the glass transition temperature (Tg) and the melting point (Tm). The polylactic acid particles have an aspect ratio of more than or equal to 1.00 and less than 1.05 and a roundness of 0.95 to 1.00. The polylactic acid particles have a flow time of 20 to 30 seconds.
