| Abstract: | The IR spectra of several samples of polyamide 6 fibres treated with solutions of different concentrations of iodine and potassium iodide were studied. The IR spectra of their respective iodine desorptions, obtained by means of treatment with sodium thiosulphate, were also studied. The spectral changes observed are related to variations in the polymorphic crystalline α and γ forms of the polyamide, which demonstrate the formation of a complex between the tri-iodide ion and the polymer during the iodine sorption process and a structural change during desorption. |
