Properties of pure chitosan fiber
摘要
Abstract
The appearance, composition, structure, tensile property, crimp ability and mass specific resis?tance of pure chitosan fiber were measured and compared with chitin fiber. The results showed that the cross section of pure chitosan fiber was zigzag and the longitudinal had groove, which was similar to the form of chi?tin fiber. The infrared spectra peak shape and peak position of pure chitosan fiber were consistent with those of chitin fiber. The characteristic peaks of X-ray diffraction of pure chitosan were consistent with that of chitin fiber. The breaking strength, elongation at break, initial modulus and work of fracture were larger than those of chitin fiber at dry state. The moisture regain of pure chitosan fiber was 16.41%, which was higher than that of chitin fiber. The crimp number, crimp ration and elastic recovery of curl rate of pure chitosan fiber were all larg?er than those of chitin fiber. The mass specific resistance of pure chitosan fiber was smaller than that of chitin fiber.关键词
