Cellulose/starch/HALS composite fibers extruded from an ionic liquid

The composite fibers of cellulose, starch, and a commercial hindered amine light stabilizer have been produced in various concentrations of the components using 1-butyl-3-methylimidazolium chloride as the spinning solvent in order to evaluate their physical properties. The composite fibers allowed desirable properties of both polymers to be retained, while producing fibers of reasonable physical properties. The halogenated hindered amine light stabilizer exhibited remarkably good resistance towards repeated ultraviolet light irradiation and halogenation cycles.
