准确地识别纤维对于保鲜人员来说很重要，这样就可以采用最合适的处理方法。本研究致力于开发一种用于表征纤维素(植物)纤维的ATR FTIR(衰减全反射傅立叶变换红外)光谱技术。研究人员检查了6种纤维，主要来自韧皮类(亚麻、大麻、黄麻和苎麻)以及棉花和剑麻。最初，未加工的纤维被考虑；随后，来自各种来源的加工纤维被检查。采用峰值强度比技术根据木质素相对于其他细胞成分的相对含量来区分纤维类型。研究发现，对于每一种纤维，这些比率都在特征范围内。
The accurate identification of fibres is of importance to conservators, allowing the most appropriate methods of treatment to be employed. This research has concentrated on the development Of an ATR FTIR (attenuated total reflectance Fourier transform infrared) spectroscopic technique for the characterization of cellulosic (plant) fibres. Six species of fibre were examined, taken largely from the bast group (flax, hemp, jute and ramie), as well as cotton and sisal. Initially, unprocessed fibres were considered; subsequently, processed fibres from a variety of sources were examined. Peak intensity ratio techniques were employed to differentiate the fibre types on the basis of relative lignin content with respect to other cellular components. It was found that, for each of the species of fibre, the ratios fell within characteristic ranges.
