摘　　要：亚麻短纤维是一种可再生的绿色环保纤维,因果胶等杂质含量高,致使前处理效果不佳,制约其加工和应用。利用过氧化尿素进行漂白,并对漂白前后的亚麻短纤维进行X-射线衍射、红外光谱、扫描电子显微镜及热性能分析和对比。结果表明:漂白亚麻短纤维结晶度下降,表面平整、光滑,分裂程度提高,漂白效果较好。The short flax fiber was a recycling and environmental fiber,but it had high content of impuri⁃ties such as pectin,which resulted in poor pretreatment effect and restricted its processing and application.The short flax fibers were bleached by urea peroxide.The short flax fibers before and after bleaching were tested and compared by X-ray diffraction,infrared spectrum,scanning electron microscope and thermal analy⁃sis.The results showed that after bleaching,the crystallinity of short fiber decreased,the surface was flat and smooth,the degree of splitting was improved,and the bleaching effect was good.
