<p>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.</p>
