摘要
桑皮纤维是一种有待于深度开发的新型天然纤维材料,其良好的环保特性倍受大家关注。本论文主要研究天然桑皮纤维的形态结构、聚集态结构和机械性能,采用数字式光学显微镜、扫描电子显微镜观察和研究了桑皮纤维的纵向表面和横截面形态特征;利用红外光谱仪、X射线衍射仪、偏光显微镜等现代物理测试分析方法,对桑皮纤维的内部结构进行了研究。通过实验,研究了桑皮纤维在标准状态和湿态条件下的力学性能,对比分析了桑皮纤维经不同浓度NaOH溶液处理和不同温度热处理后,桑皮纤维的结构和力学性能的变化规律,分析桑皮纤维力学性能产生变化的内在因素,以此探明不同的外界条件作用对桑皮纤维的纺织加工和产品应用有何重要影响。通过本论文的研究,可以为桑皮纤维的工业化生产和产品开发提供一定的理论依据。
Mulberry bark fiber is a kind of new natural fiber, and its eco-friendly characteristics are drawing more and more attentions. This thesis aims to research the morphological structure, aggregate structure and mechanical properties of natural mulberry bark fiber. By the use of digital optical microscope and scanning electron microscope (SEM), the author observes and researches the surface of the longitudinal and cross section of the mulberry bark fiber; and by the use of modern mechanical testing and analyzing methods like infrared spectrometer, X-ray diffractometer, polarizing microscope and thermal analyzer and so on, the author also makes research on the inner structure of the mulberry bark fiber. Through experiments, the author studies the mechanical properties of the mulberry bark fiber in the standard and hygrometric state, and makes contrast analyses on the law of the changes about the structure and the mechanical properties in different concentration of NaOH solutions and heat treatments in different temperatures, and further explores the intrinsic factors on the changes of the mechanical properties of the mulberry bark fiber. All these researches contribute to the important effects to the spinning machining and products applying in different external conditions. Therefore this thesis serves to provide some theoretical basis to the commercial process and product development of the mulberry bark fiber.
