1. A method for spinning a composition that includes a starch-based polymeric material to produce a spunbond nonwoven therefrom, the method comprising:
providing a composition that includes a starch-based polymeric material;
wherein the starch-based polymeric material has a crystallinity of less than about 20%, and resists recrystallization; and
melt spinning the composition to produce fibers including the starch-based polymeric material, wherein the composition exhibits a shear viscosity of above 50 Pa·s and no more than about 300 Pa·s at 190° C. at a process shear rate of 200 s−1 and avoids onset of melt flow instability during melt spinning.
