Abstract :
Absorption spectra of cellulosic fibers in THz region show discriminative absorptions which are derived from crystallized cellulose, when we prepare the samples by cutting at a length of about 0.1-0.2 mm. The blending ratio of two different kinds of fibers has been examined by using this method, and the spectra were analyzed by an analysis of principal component as a multiple classification analysis after the first derivation of the spectra. The result means the blending ratio can be identified with considerable accuracy at a few percent of reliability.
