棉纤维是天然植物产品，其最终使用质量取决于其发育阶段。一般而言，棉纤维中的纤维素含量增加较快，从而导致生长期较短和较长的纤维在组成、结构和物理属性上存在差异。本文讨论了傅里叶变换红外光谱技术在表征这些差异、区分未成熟纤维和成熟纤维、评估纤维成熟度和结晶度以及解开结晶和非晶态纤维的谱带归属方面的最新进展。结果是通过使用各种策略来实现的，包括湿化学分析、主成分分析(PCA)、SIMPLE算法开发、二维相关分析和其他独立的纤维测试。特别令人感兴趣的是，一般而言，未成熟纤维可能具有低于21-28dpa、MIR<；0.58(在成熟度0-1.0范围内)和CIIR<；42%(在结晶度0-100%范围内)的特性。
Cotton fibers are natural plant products, and their end-use qualities depend on their stages of development. In general, the quantity of cellulose in cotton fibers increases rapidly, thus it leads to compositional, structural and physical attribute variations among the fibers with shorter and longer growth periods. This article discusses recent progress in applying the Fourier transform infrared (FTIR) spectroscopic technique to characterize these differences, to discriminate immature fibers from mature fibers, to assess fiber maturity and crystallinity and also to unravel the band assignments in crystalline and amorphous celluloses. The results were achieved through the use of various strategies, including wet chemical analysis, principal component analysis (PCA), simple algorithm development, two-dimensional correlation analysis and other independent fiber tests. Of particular interest is that, in general, immature fibers might have the characteristics of less than 21–28 dpa, MIR < 0.58 (in the maturity range of 0 to 1.0) and CIIR < 42% (in the crystallinity range of 0 to 100%).
