摘要几十年来，野生非桑蚕丝主要用作纺织纤维和生物医用缝合线。在这项研究中，我们报道了一种独特的野生蚕丝品种--香樟丝。与家蚕（B. mori）蚕丝和柞蚕（Antheraea pernyi（A. pernyi）蚕茧，樟脑蚕茧较小并且具有较薄的茧壁。与A.除了pernyi茧外，樟脑茧的外层也有大量的晶体。脱胶前后的樟脑丝的断裂强力和断裂韧度均显著高于A。pernyi和B.森丝绸。此外，傅里叶变换红外光谱（FTIR），X射线衍射（XRD）和热重（TG）分析，提供了一个洞察的上级力学性能的樟脑丝。结果表明，樟脑丝具有较高的结晶度和较高的分解温度（329 °C），这有助于其优异的力学性能。该研究为复合材料和生物医学器件提供了一种新的替代蛋白质材料。
Abstract Wild non-mulberry silk has long been mainly used as a textile fiber and as biomedical sutures for decades. In this study, we reported a unique wild silk variety, the Camphor silk. Compared with the Bombyx mori (B. mori) silk and Antheraea pernyi (A. pernyi) silk cocoons, the Camphor silkworm cocoon is smaller and has a thinner cocoon wall. Similar to the A. pernyi cocoon, the Camphor cocoon also has a large amount of crystals covering its outer layers. The breaking strength and tenacity of the Camphor silk with and without degumming were significantly higher than that of A. pernyi and B. mori silks. Moreover, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermo gravimetric (TG) analyses were employed to provide an insight into the superior mechanical properties of the Camphor silk. The results showed that the Camphor silk has a high degree of crystallinity and high decomposition temperature (329 °C), which contribute to its outstanding mechanical properties. This study provides a new alternative protein material for composites and biomedical devices.
