Identification of several kinds of textile fibers and detection of composition of mixed fibers were studied by infrared absorption spectra.
The results are as follows:
Identification of textile fibers is generally simple.
Detection of functional groups in mixed fibers is easily performed by the use of characteristic absorption band.
For this method the necessary amount of samples are very small, but when the same functinal groups existed in each fiber, the detection of compositions of mixed fibers are difficult because the characteristic absorption bands are similar.
It is more effective to use together the two auxiliary means of microscopic and dissolving methods together for the more effective identification of the compositions of mixed fibers.
