摘　　要：采用高碘酸钠对亚麻短纤维进行选择性氧化,探讨了高碘酸钠用量和反应时间对醛基含量、断裂强度、失重率和分裂度的影响。结果表明：高碘酸钠的最佳用量为6～7 g/L,最佳反应时间为50～55 min,此时的亚麻短纤维各项性能指标满足可纺性要求。Flax short fiber was selectively oxidized with sodium periodate. Effects of oxidized concentration and reaction time on aldehyde group content, breaking strength, weight loss ratio and split degree of oxidized flax short fiber were investigated. Results showed that the flax short fiber performance indicators were able to meet the requirements of spinnability in the case of the optimized usage of sodium periodate 6～7 g/L and the best reaction time 50～55 min.
