METHODS FOR MAKING POLYLACTIC ACID STEREOCOMPLEX FIBERS
摘要
<p>PLA stereocomplex fibers are made by separately melting a high-D PLA starting resin and a high-L starting resin, mixing the melts and spinning the molten mixture. Subsequent heat treatment introduces high-melting "stereocomplex" crystallinity into the fibers. The process can form fibers having a high content of "stereocomplex" crystallites that have a high melting temperature. As a result, the fibers have excellent thermal resistance. The process is also easily adaptable to commercial melt spinning operations.</p>
