3种蚕丝结构与性能初探

Preliminary study on the structure and properties of three different silks

蚕丝纤维具有良好的服用性能，为了研究并提高蚕丝的利用价值，采用扫描电镜、红外光谱仪、X射线衍射仪、TG-DTG分析仪等对桑蚕丝、柞蚕丝和木薯蚕丝的形态结构以及热学性能进行测试与分析。研究结果表明，木薯蚕丝的表面形貌与柞蚕丝类似，表面沿纵向存在多条凹凸不平的裂纹，而桑蚕丝表面平整光滑；从3种蚕丝的X-射线衍射强度曲线以及红外光谱曲线可以看出，3种蚕丝在整体结构上没有明显差异；从热分析的测试结果来看，木薯蚕丝和柞蚕丝的热稳定性较桑蚕丝好，其良好的热学性能特点为蚕丝复合材料的开发奠定了一定的基础。

The silk fiber has good service performance. In order to study and improve the utilization value of silk, infrared spectroscopy, X-ray diffraction, thermal analysis etc are used to test and analyze the morphological changes and the thermal properties of three kinds of silk. The results show that the surface morphology of cassava silk is similar to that Of tussah silk, there are many irregular cracks on the surface along the longitudinal direction, while the surface of silk is flat and smooth. From the X-ray diffraction intensity curve and infrared spectrum curve, it could be seen that there is no obvious difference in the overall structure of three kinds of silks. Based on the test results of thermal analysis, the thermal stability of cassava silk and tussah silk is better than mulberry silk, and its good thermal properties are silk composite materials to lay a solid foundation for the development.
