Abstract

Methods of preparing mono- and multi-component fibers comprising polylactic acid (PLA) are described. Exemplary fibers include co-extruded bicomponent core-sheath fibers where the core includes PLA and the sheath includes polyolefin. The fibers can include various colorants, such as colorants derived from natural materials and/or flame retardants. Also described are fibers comprising PLA, e.g., the fibers prepared by the disclosed methods, and related articles, such as textiles, clothing, synthetic fibers, and faux fur.
