Applications and development of Fourier Transform Infrared(FTIR) Spectroscopy in textile determination were summarized in the paper.The techniques of sample preparation and determination were discussed,concerning those of infrared transmission and reflection(such as mirror reflection,diffuse reflection and attenuated total reflection),photo-acoustic spectroscopy,infrared microspectroscopy for qualitative and quantitative analyses,as well as newly developed techniques of FTIR,which was expected to be a good ...
