Abstract
Small Angle X-ray Scattering due to degummed ramie fibres were recorded using a Compact Kratky Camera, having counter device. The fibres were taken both in natural state and alkali treated state at room temperature. Various macromolecular parameters, such as D the average periodicity transverse to layer, S/V, the specific inner surface, E, the width of transition layer, T1, T2, Tr, transversal lengths lc length of coherence etc. were calculated by using the correlation functions of the smeared out scattering curve of the different samples. Increase in the value of D with concentration of sodium hydroxide solution may be due to swelling of macromolecules present in the fibre. The calculation of various parameters were done by applying theories of Ruland14 and Vonk.7
