Starch is a promising bio-based material to replace synthetics in a number of applications. The production of starch-based fibers has been actively pursued in the patent literature. This article reviews patents on starch fiber technology, including fiber spinning from amylose, thermoplastic starch compositions, and non-thermoplastic starch compositions. Some new fiber spinning techniques, e.g. electrospinning and rotary jet spinning, employed for spinning starch fibers are also presented.
