A method of infra-red spectroscopy and deuterium exchange were used to investigate the inaccessible phase in viscose fibres of standard, polynosic and cord type, taking an advantage of the resistance of this phase to different NaOD concentrations.
It has been found that the function ε=f(CNaOD) is characteristic for appropriate crystalline structure in celluloses regenerated from viscose. The observed differences of the function are particularly prominent for various types of viscose fibres, being also measurable within the same type of fibres. The presented observations are in good agreement with generally accepted X-ray diffraction data.
