Quizplus · Accepted Answer

FTIR (Fourier transform infrared spectroscopy) and PyGC (pyrolysis gas chromatography) are the two major methods used to analyze the chemical composition of fibers. FTIR is used to identify the chemical functional groups present in a fiber, while PyGC is used to analyze the individual components of a fiber by breaking it down into its constituent parts. Both of these methods are complementary and necessary for a comprehensive analysis of fiber composition. Microscopy and chromatography may also be used in fiber analysis, but they are not the two major methods typically used.
