1. A method for producing yarn fibers from a composition that includes a starch-based polymeric material, the method comprising:
providing a composition that includes a starch-based polymeric material;
spinning the composition to produce yarn fibers having an as spun diameter from about 40 μm to about 150 μm, the yarn fibers including the starch-based polymeric material, wherein the composition exhibits a shear viscosity of greater than 50 Pa·s and no more than about 600 Pa·s at 190° C. at a process shear rate of 200 s−1, and avoids onset of melt flow instability during spinning of the yarn fibers; and
drawing the as spun yarn fibers from their spun diameter down to a smaller diameter.
