【摘要】 本研究是在前人所确认的丝绸舒适保健功能的基础上，通过 比较蚕丝纤维与其他织物纤维在结构上的差异，重点从服装的微 气候和抗菌、防菌性角度研究丝绸服饰的舒适性、保健性，并阐 明其原因，为进一步开发功能性丝绸内衣提供依据。 通过对蚕丝及其织物与其他纺织纤维织物的电镜观察和吸 湿、放湿性能的比较，证实蚕丝纤维具有表面光滑、内部多孔的 结构特征，在不同的相对湿度和温度组合条件下，蚕丝织物的单 位重量吸水量和回潮率明显高于其他纤维织物。揭示了蚕丝纤维 结构与丝绸服饰的吸湿、放湿性能的关系，确认丝绸服饰能给人 体提供适宜的服装微气候，发挥其舒适防护的保健功能。 通过采用振荡瓶法和带菌性实验，对未经任何抗菌、抑菌处 理的丝素、丝绸和其他纺织品的抗菌性能进行比较研究，结果表 明丝绸对大肠杆菌、枯草芽孢杆菌、酵母菌的抑菌率分别为98.3%、 98.5%、99.4%，丝素粉对大肠杆菌、枯草芽孢杆菌抑菌率为90.2%、 92.2%，抑菌能力高于天然纤维棉、麻，明显高于涤纶、尼龙等合 成纤维，表现出很强的抑菌作用；同时由丝绸的防菌试验结果可 知，丝绸的带菌数为95个，而棉、麻、涤纶、尼龙的带菌数分别 为132、789、348、799，丝绸的防菌能力明显强于其他纺织品。 从而从微生物学角度证明了丝绸服饰对人体皮肤的保健作用，这 是山于蚕丝蛋白中的氨基酸对微生物具有抑菌作用之故。更多还原

【Abstract】 Silk cloth was recognized to have striking curable effect on skinscratchness of human body and showed excellent comfortable andhealthy function based on the quite lots of survey and research at chinaand abroad, but studies on the mechanism of above function waslimited. In order to clarify internal cause of comfortable and healthyfunction of silk cloth, difference in structure, micro-climate of cloth andanti-bacterial property between silk and other fabrics was compared inthis paper.More smooth surface and significant porosity in silk filament thanin others were observed with electron micro-scope. Under differentcombinations of relative humidity and temperature, silk fabric had moremoisture absorption per weight and higher moisture regain than othersand showed superior absorption and desorption property, with whichcomfortable micro-climate of cloth to human body was provided.Therefore, silk cloth showed comfortable and healthy function.The anti-bacterial properties between sericin, silk and other fabricswithout treatment were compared. Silk showed better anti-bacterialproperty than other natural fabrics, cotton and flax, and synthetic fiberssuch as delon and nylon. The anti-bacterial rate of silk, for Escherichiacoll; is 98,3%, fOr Bucillus subtilis, is 98.5%, fOrYeast, is 99.4%. Thea11ti-bacterial rate of sericin, for Eschericlia coli, is 90.2%, fOr BlIcilllISsubtilis, is 92.2%. The number of bacteria in silk fabric is 95, much lessthan in other fabrics that cotton is l32, flax 789, delon 348 and 11ylon799. Through microbiological experiments, healthy function of silkcloth was approved that amino-acid of silk protein prevented microbegrowing and reproducing on human body更多还原
