Melt-spun polylactic acid fibers: effect of cellulose nanowhiskers on processing and properties.

This is the pre print version of the work. The definitive version is published in the Journal of Applied Polymer Science, vol. 127(1), pp 274-281Bio-based continuous fibers were processed from polylactic acid (PLA) and cellulose nanowhiskers (CNWs) by melt spinning. Melt compounding of master batches of PLA with 10 wt % CNWs and pure PLA was carried out using a twin-screw extruder in which compounded pellets containing 1 and 3 wt % of CNWs were generated for subsequent melt spinning. The microscopy studies showed that the fiber diameters were in the range of 90-95 mm, and an increased surface roughness and aggregations in the fibers containing CNWs could be detected. The addition of the CNWs restricted the drawability of the fibers to a factor of 2 and did not affect the fiber stiffness or strength, but resulted in a significantly lower strain and slightly increased crystallinity. Furthermore, CNWs increased the thermal stability, creep resistance and reduction in thermal shrinkage of PLA fibers, possibly indicating a restriction of the polymer chain mobility due to the nanoscale additives.enMelt spinningPolylactic acidCellulose nanowhiskersThermal propertiesShrinkagePolylactic acid fibersPLAArticleJohn, M.
