【摘要】 本论文全面、详细地研究了真丝纤维经盐缩处理后的形态、结构及其特性变形，结果显示，盐缩丝纤维内部微空隙增多，纤维间截面饱满性提高，同时其特性性能发生了根本的改变。研究了超低温冷冻对丝纤维结构及其性能的影响，同时亦研究了微波辐照对丝纤维的热效应和非热效应作用；详尽地探讨了冷冻、微波相结合下丝纤维的形态、结构及其性能，并进行了相应的对比，其结果是，超低温冷冻和短时间微波辐照都能在一定程度上改善丝纤维的各项性能，长时间微波辐照和冷冻、微波相结合处理均能造成丝纤维内部付价键结构的破坏，同时纤维自身发生了明显的热胀作用，从而使得纤维内部组织疏松、微空隙增多。 通过对真丝纤维进行低温氧等离子体处理后发现，在基本不改变纤维本体力学性能的前提下，可以通过低温等离子体处理来使真丝纤维表面产生微空隙。 运用计算机图象处理和编程技术求出了真丝纤维的内部空隙率和纵向表面空隙率。其结果表明，盐缩丝纤维的单纤维内部空隙率最大，其次是冷冻、微波相结合处理丝纤维，然后是微波辐照丝纤维，未处理原丝纤维最小，而纤维内部总体空隙率的排序规律正好相反；对于纤维的纵向表面空隙率，等离子体处理丝纤维明显比未处理原丝纤维大。更多还原

【Abstract】 The morphology, structure and characteristic deformation of the silk fiber treated by salt solution is fully and detailedly studied in this paper. The experiment shows that the number of the inner microporosity increases and the satiation of the fibers cross-section increases, and the characteristic properties change radically. The structure and properties of the silk fiber treated by super low temperature freezing is investigated. Also the thermal domino effect and non-thermal domino effect of silk flyers treated by microwave is illustrated. In addition, the morphology, structure and properties of silk fibers are studied when the fibers are treated by super low temperature freezing combined with microwave. And the results are that both super low temperature freezing and short-time microwave irradiating can improve each property of silk fiber, and that long-time microwave irritating or using freeing combined with microwave method can destroy the inner second bond of silk fibers. And because of swelling of the silk per se, the structure become loose and the number of microvoid rise. The microporosity on the surface of silk fibers can be obtained by the low-temperature oxygen plasm treatment while the mechanical properties of the silk fibers barely change. Use computer image process technology to calculate the inner void ratio and lengthwise surface void ratio and find the inner void ratio of single silk treated by the salt solution is the biggest, then is the combined methods (using freezing and microwave irritating together), and then is the microwave irritated silk fibers and the inner void ratio of untreated silk fibers is the smallest. And the rule of whole inner void ratio is contrary to that of the inner void ration. As for lengthwise surface void ratio, the silk fiber treated by plasm is more obvious than untreated silk fibers.更多还原
