Abstract:

In order to improve the mechanical properties of polylactic acid (PLA) melt blown nonwovens, samples of PLA melt blown nonwovens with high crystallinity were prepared by a large scale and one step post-drafting assisted melt blown process, based on the experimental analysis of the thermodynamic properties of PLA polymers. The morphology, tensile and bursting properties of the prepared samples were evaluated. The results show that the glass transition temperature and melting point of PLA were 60.69 ℃ and 162.6 ℃, respectively, suitable for the preparation at a high drafting ratio during the post-drafting assisted melt blown process. It was noted that with the drafting ratio increasing from 1.0 to 3.0, the proportion of high-oriented fibers (fiber orientation angle≤20°) was increased from 28% to 100%, and the proportion of the microfibers (fiber diameter ≤3 μm) was increased from 23% to 67%. The drafting ratio increase also caused the crystallinity to increase from 1.22% to 37.43%, the tensile breaking strength in machine direction to reach 4.33 N/mm2, and the bursting force to 36.8 N, demonstrating improvement of the mechanical properties of the PLA melt blown nonwovens due to the post-drafting assisted melt blown process.
