天然黄色家蚕丝纤维与其他蚕丝纤维的形态结构比较

为了进一步促进彩色蚕丝的开发和应用,研究了通过杂交育种获得的天然黄色家蚕茧丝的外观形态和截面结构特征,并与普通白色家蚕丝、柞蚕丝和来自柬埔寨的多化性黄茧家蚕丝进行了比较研究。结果显示:天然黄色家蚕丝纤维的横截面形态主要呈三角形,与普通白色家蚕丝、多化性黄茧家蚕丝纤维的横截面形态相似,而柞蚕丝的横截面形态呈长椭圆形。天然黄色家蚕丝的颜色鲜艳,光泽感优于普通白色家蚕丝和柞蚕丝。离子刻蚀显示,天然黄色家蚕丝纤维内部的原纤表面组织结构比普通白色家蚕丝紧密。

Comparison of Morphological Structure of Nature Yellow Silkworm Silk Fiber With Other Silk Fibers

To promote the development and application of multicolor silk,the morphological structure of the nature yellow silkworm silk from a silkworm variety,selected by cross breeding method,was investigated by SEM and compared with the normal white silkworm silk,the golden wild silkworm silk from Cambodia,and the Antheraea pernyi silk,respectively.Results shown that the morphological structure of the nature yellow silkworm silk fiber was triangle,more close to the normal white silkworm silk fiber,the golden wild silkworm silk fiber also was close to triangle,but the Antheraea pernyi silk fiber was close to oval.The gloss of the nature yellow silkworm silk was better than the normal white silkworm silk and the Antheraea pernyi silk.The ionetching experiment results showed that tissue structure of the nature yellow silk was tighter than that of the normal white silkworm silk.
