NOVEL COMPOSITION FOR PREPARING POLYSACCHARIDE FIBERS

摘要

Solutions formed by combining poly(a(1?3) glucan) with CS2 in aqueous alkali metal hydroxide solution have been shown to produce the xanthated form of the poly(a(1?3) glucan). The solutions so formed have been shown to be useful for solution spinning into fiber of poly(a(1?3) glucan) when the spun fiber is coagulated in an acidic coagulation bath. The fibers so produced exhibit desirable physical properties. The poly(a(1?3) glucan) employed was synthesized by fermentation.
