摘　　要：通过测定竹、棉、麻、木的纤维素纤维的红外吸收光谱,并利用红外光谱仪数据处理软件设定标峰灵敏度,研究多种纤维素纤维光谱的细微差异,分析各天然纤维素纤维的结构差别,及碱对天然纤维素纤维结构的影响。研究发现棉、麻、木纤维在1 110 cm-1处红外吸收都强于竹纤维,在993 cm-1处的吸收峰弱于竹纤维;经NaOH溶液处理后,各纤维的红外谱图均发生细微变化。从中揭示出各天然纤维晶格有一定的差异,并认为竹纤维的非结晶区含量较多,这是引起竹纤维吸湿性、凉爽性比棉好的原因。Though measuring the Fourier transform infrared （FrIR） spectra of bamboo, cotton, hemp and wood cellulose fiber at a certain marking peak sensitivity, we studies the small differences in F-FIR spectra absorption peaks of various natural cellulose fibers. Also we investigate the discrepancy in structures of diversified natural cellulose fibers and the effects of base to the structures of fibers. It was found that the absorption peak of bamboo fiber at 1110 cm^-1 is weaker than other various fibers, including cotton, hemp and wood cellulose fiber, and is stronger than those of fibers at 993 cm-1. The infrared spectrum of fibers slightly changed after treatment with NaOH solution, revealing the lattices of all natural fibers have some differences, and the bamboo fiber have more non-crystalline areas. This may explain why bamboo fiber is better than the cotton in the properties of hygroscopicity and coolness.
