Biodegradation in saline and thermal and mechanical properties of multifilament PLA fibers (diameter 18 μm) and monofilament PLA fibers (diameter 150 μm) were studied. Differential scanning calorimetry measurements show that higher degree of crystallinity and shift of melting interval to higher temperatures correlates with lower rate of biodegradability. Sharp decrease of melting enthalpy in second heating correlates with higher rate of biodegradation of PLA fibers. Further experiments with other PLA fibres are needed to elaborate and validate the application of DSC method in quality assessment system for PLA fibers tailored to be used in scaffolds. Further studies can provide opportunities for development of new design technology for production of scaffolds with tailored biodegradation rates.
