In vitro degradation of poly( L-lactic acid) fibers was investigated for a period of 16 weeks in Ringer solution at 37ΠC. Two sets of fibers, with similar initial mechanical properties, molar mass, and crystallinity content, but markedly different in diameter (72 and 120 mm) were studied. Viscometri

Poly(L-lactic acid) filaments were prepared by high speed melt spinning at take-up velocities up to 5000 m/min. The crystallinity, birefringence, tensile strength, Young's modulus and yield strength all exhibit maxima at take-up velocities between 2000 and 3000 m/min. The boiling water shrinkage exh
A polylactide (PLA type LA 0200 K) was spun in high-speed melt spinning and spin drawing processes. The fibers were characterized with regard to the degree of crystallinity, the orientation, and the textile physical properties. The polymer was produced by a reactive extrusion polymerization process,
