Abstract [en]

The dry-jet-wet spinning process was employed to spin poly(lactic acid)(PLA) fiber by the phase inversion technique using chloroform and methanol as solvent and nonsolvent, respectively, for PLA. The as spun fiber was subjected to two-stage hot drawing to study the effect of various process parameters, such as take-up speed, drawing temperature, and heat-setting temperature on the fiber structural properties. The take-up speed had a pronounced influence on the maximum draw ratio of the fiber. The optimum drawing temperature was observed to be 90°C to get a fiber with the tenacity of 0.6 GPa for the draw ratio of 8. The heat-setting temperature had a pronounced effect on fiber properties.
