Fourier transform infrared spectra of the textile surfaces

Infrared spectroscopy is used to identify and quantitatively analyse chemical compounds, mixtures, extent of reaction, and molecular stmcture. Various chemical compounds absorb infrared radiation at frequencies corresponding to their own molecular vibrational frequencies. Fourier transform infrared spectra of the textile surfaces is carried out to determine the functional groups and the extent of the reaction of the bioactive groups with the textile. 

Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is used to obtain spectra of powders and rough polymeric surfaces such as textiles and paper. IR radiation is focused onto the surface of the sample in a cup resulting in both specular reflectance (which directly reflects off the surface having equal angles of incidence and reflectance) and diffuse reflectance (which penetrates into the sample subsequently scattering in all angles). Special mirrors allow the specular reflectance to be minimized.
