摘要

A commercially available PLA being developed for melt blowing application was processed under various conditions and with a processing aid using a melt blowing pilot line. Produced nonwoven samples were studied by scanning electron microscope (SEM), capillary flow porometer, absorbency and air permeability testing system. In addition, the physical and mechanical properties of nonwoven fabrics were determined. A detailed analysis of the influence of the processing conditions on the microstructures of PLA fibers showed the importance of an additive, as well as process air pressure and throughput rate on fiber diameter and diameter distribution. Results indicate that a decrease in fiber diameter and diameter distribution can be achieved by the addition of an additive at low processing air pressures.
