摘　　要：研究亚麻纤维碱-尿素化学改性.通过改性前后纤维的SEM照片、X衍射等方法表征亚麻纤维微观结构的变化.结果表明,改性后纤维的结晶度下降明显,纤维表面光滑,纤维分离程度增大.同时探讨了亚麻化学处理后纤维结构和性能的关系,为亚麻化学改性奠定理论基础.Studying on the chemical modified flax fibers under the condition of alkali-urea, the method is used to characterizate flax fibers＇ micro-structure with Scanning Electron Microscope and X-ray graph. The results show that the crystallinty of flax fibers is decreased, surface smoothness is improved and degree of separation is increased. Meanwhile, the relation is studied between the flax fibers＇ micro-structure and properties. It can be a reference for chemical modified flax fibers.
