Application of Internal Reflection Spectroscopy to the Quantitative Analysis of Mixed Fibers
Internal-reflectance spectroscopy has proved to be an excellent method for the qualitative identification of fibers both in the raw state and in fabrics. In the present study the technique has been applied to the recording of infrared spectra of a number of fabrics woven from two or more types of fibers. Infrared spectra can be obtained directly from the fabric with no special treatment. A number of factors affect quantitative accuracy. With careful control of these factors spectra of quantitative value can be obtained on many mixed fabrics. Special techniques have been developed aimed at maximizing the quantitative accuracy.
