摘要
利用光学显微镜和扫描电镜研究木棉纤维的表面结构,利用单纤维强力测试仪测试木棉纤维的拉伸性能,测得断裂强力为0.3—0.7cN,断裂伸长率为4%-8%.利用红外光谱仪确定木棉纤维的分子组成和结构,利用x射线衍射仪测得木棉纤维的结晶度约为36%,对木棉纤维的细度和回潮率进行了测试,并对实验结果进行了合理的分析.
By means of optical microscope and scanning electron microscopy the surface structure of kapok fiber is studied, and the single fiber strength test instrument on the tensile properties is used to test the kapok fibers, the strength is 0.3 - 0.7 cN and the elongation is 4% - 8%. With the infrared spectrometer the molecular composition and structure of kapok fiber is determined. Using X - ray diffraction measurement, kapok fiber crystallinity is tested as 36% and the fineness and moisture regain of the fibers are tested. Analy- sis is made on the results.
