Polylactide (PLA) multifilaments, false-twist textured at different temperatures (135, 150 and 165ºC) and draw ratios (1.30, 1.35 and 1.40) have been stabilized by a continuous post setting treatment at 50 m/min and 100ºC using a specially designed chamber. The crystallinity of the original textured filaments and those of the stabilized ones has been measured. The effect of post setting on the thermomechanical behaviour according to the texturing conditions has been studied. The relationship between crystallinity and both relaxation shrinkage and maximum phase lag temperature have been pointed out
