Dry Spinning of PLA

The ambient temperature at the spin line has a profound influence on the

Leenslag et al. [42] obtained PLA fibers with a loosened fibrillar strueture by solution spinning from a good solvent (chloroform) in the presence of various additives. Spinning was carried out at room temperature with ehloroform as the 

The morphology of fiber is significantly affected by precipitant vapor. The structure of osr-spun fiber in petroleum ether vapor as precipitant is characterized by an irregular skin and porous inner part due to very fast phase separation. In ethanol vapor phase separation rate is very slow, which gives a surface similar to that of dry-spun fiber. The fiber spun in methanol vapor as a precipitant has no 

The composition and nature of the solvent play an interesting role in the morphological development of the fiber and its mechanical properties. The
