Articles of manufacture which comprise biodegradable fibers and fabrics made therefrom. The fibers are made from starch-based biodegradable thermoplastic polymers, which preferably include a an additional biodegradable thermoplastic polymer blended with thermoplastic starch for improved chemical and physical properties. Threads or fibers for the manufacture of these articles are drawn in a process that improves their mechanical properties, particularly their strength. These threads or fibers can be used in the manufacture of articles that have open, semi-densely packed or densely packed structures.

[ What is claimed is:] [1.]1. A fibrous article of manufacture comprising at least one fiber manufactured from a thermoplastic polymer blend including thermoplastic starch and at least one additional polymer other than starch, wherein the fiber manufactured from the thermoplastic polymer blend has been drawn at a temperature below the melting point of the thermoplastic polymer blend so as to increase the breaking strength of the drawn fiber compared to the breaking strength of the fiber prior to being drawn.
