利用近红外光谱技术对竹原纤维、 竹粘胶纤维和苎麻纤维进行了快速定性鉴别研究。 首先扫描3种纤维的近红外光谱, 利用化学计量学分析软件, 对谱图进行一阶导数预处理, 建立不同纤维的光谱数据库, 并分别建立竹原纤维、 竹粘胶纤维和苎麻纤维的判别模型。 利用判别模型, 对未知样品进行判别。 结果表明, 近红外光谱可以在不破坏样品的情况下, 可以快速鉴别竹原纤维、 竹粘胶纤维和苎麻纤维。

The research on discrimination of natural bamboo fiber, bamboo pulp fibers and ramie fiber used in textile was demonstrated by near infrared (NIR) spectroscopy. First, the spectra of three kinds of fiber were scanned by NIR spectrometer. Then, the spectral data were pretreated by first derivatives. In the end, the databases and discriminating model of natural bamboo fiber, bamboo pulp fibers and ramie fiber were built. The kind of unknown fiber can be discriminated by the NIR model. The results indicated that the natural bamboo fiber, bamboo pulp fibers and ramie fiber can been discriminated quickly by NIR spectroscopy without destroying samples.
