FIG. 2.

(a) Schematic of the meltblown fabric sheet demonstrates the direction of mechanical testing in relation to the direction of travel of the collector for the meltblowing apparatus. Representative stretch-strain curve (b) for 6100D PLA meltblown scaffolds taken from Roll A. Mean ± SD Young's modulus (c) yield stress (d), and yield stretch (e) in 6100D PLA meltblown scaffolds tested in orthogonal directions, n = 6. Groups with different letters above are significantly different from each other, p < 0.05. Data for other blends of PLA can be found in Supplementary Figure S2.
