Introduction and statement of the problem
The polymerization of lactic acid yields polylactic acid. As such, the raw material used in the manufacture of polylactic acid is lactic acid. Lactic acid is a naturally occurring substance that is produced by living things during metabolism. The use of polylactic acid in the production of fibers for various applications in the textile industry can be traced back to a very useful discovery a few decades ago. The production of biodegradable surgical sutures using polylactic acid set the path clear for more applications of polylactic acid (Ren 98). The good ...
