摘要: 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.

摘要: Conjugate fibers are prepared in which at least one segment is a mixture of a high-D PLA resin and a high-L PLA resin. These segments have crystallites having a crystalline melting temperature of at least 200° C. At least one other segment is a high-D PLA resin or a high-L PLA resin. The conjugate fibers may be, for example, bicomponent, multi-component, islands-in-the-sea or sheath-and-core types. Specialty fibers of various types can be made through further downstream processing of these conjugate fibers.
