摘要
结晶度指数(CI)是评估棉纤维质量的一个重要参数。由于从 X 射线衍射 (XRD) 图样中测量 CI 既简单又快速,Segal 方法被广泛使用。在本研究中,我们通过比较 Segal CI 与基于傅立叶变换红外光谱的方法和其他基于 XRD 的方法所获得的 CI,评估了 Segal 方法在花后 20 天至 60 天(DPAs)监测棉花(Gossypium L.)纤维结晶度演变的效果。与其他方法相比,西格尔方法估算出的 CI 值更高,尤其是对于较短的 DPA。Segal 方法表明结晶度在早期发育阶段演变迅速,而其他方法则表明结晶度逐渐增加。对不同尺寸的纤维素 Iβ 结晶体的衍射图样进行计算后发现,对于所研究的发育中棉纤维,结晶体尺寸对 Segal CIs 的影响很小。
Assessment of Segal method for identifying crystallinity evolution in developing cotton fibers
The crystallinity index (CI) is an important parameter in evaluating cotton fiber quality. Due to its ease and speed in measuring CIs from X-ray diffraction (XRD) patterns, the Segal method is popularly used. In this study, we assessed the Segal method for monitoring the crystallinity evolution in developing cotton (Gossypium L.) fibers between 20 and 60 days post anthesis (DPAs) by comparing Segal CIs with those obtained from a Fourier transform infrared spectroscopy-based method and other XRD-based methods. The Segal method estimated higher CIs than other methods, especially for shorter DPAs. The Segal method suggested a rapid evolution of crystallinity in the early developmental stage, whereas other methods suggested a gradual increase in crystallinity. The calculation of diffraction patterns for cellulose Iβ crystallites with different sizes showed very little effect of the crystallite size on the Segal CIs for developing cotton fibers studied.
