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, and its hydrolytic degradation during the processes of drying and spinning and its thermal and rheological properties were characterized. © 1999 John Wiley & Sons, Inc.
