PLA Processing

NatureWorks PLA Processing Guide for Biaxially Oriented Film, Nature Works LLC, Minnetonka, MN, 2006. 

PLA processes and products are compared and are comparable to PET both are melt spun, both are available in filament and staple form, weaving and knitting set-up conditions are similar, fabrics can be heat treated to give dimensional stability, and they are both dyed with disperse dyes. However, both fibers are unique and they do behave differently. It is therefore important that processors acknowledge this fact, and that the operating details are refined accordingly. 

Life cycle assessment reveals that no petroleum-derived polymer can rival the greenhouse gas sink effect of the improved PLA process. Although disposal of PLA products - whether by combustion, composting or other conventional means - results in a return of carbon dioxide to the atmosphere, this advantage survives.
