Abstract:
1. A method for producing a shortened poly-β-1→4-N-acetylglucosamine fiber composition, said method comprising: (a) formulating poly-β-1→4-N-acetylglucosamine fibers into dry fibers, a dry fiber membrane or a dry lyophilized material, and irradiating the formulated poly-β-1→4-N-acetylglucosamine fibers by gamma irradiation at 500-2,000 kgy, or (b) formulating poly-β-1→4-N-acetylglucosamine fibers into a suspension, a slurry or a wet cake, and irradiating the formulated poly-β-1→4-N-acetylglucosamine fibers by gamma irradiation at 100-500 kgy,
