Electron diffraction study of regenerated celluloses like viscose, cuprammonium. and polynosic rayons revealed the presence of cellulose I as an extraneous lattice in addition to the basic cellulose II lattice, hitherto shown by x-ray diffraction stu

Analytical techniques, viz. electron microscopy, surface area determination, and swelling in cadoxen solvent, have been used to obtain results which provide positive evidence for the formation of crosslinks between adjacent cellulose chains in cotton

An accelerating potential of 75 kV combined with very low beam current and exposure time of 5 sec seem ideal for recording electron diffraction pattern of cooled specimens of cellulose microfibrils. Over 16 reflections could be seen distinctly. The s

The lateral order factor of four Indian varieties of silk, viz., Mulberry, Tasar, Eri, and Muga, were determined by electron diffraction technique and compared with that determined by x-ray diffraction. The profiles of the 002 and 201 reflections in

Structural features, viz, the fihrillar orientation, void space, micropores and ordered-disordered regions of Indian G. herbaceum cottons have been compared with those of American G. hirsutum cottons of comparable maturity range. Convolution angle an

Birefringence and structural reversals have been determined on 20 Indian cottons and correlated with their mechanical properties. The variation in spiral angles among cottons is influenced by the variation in convolution angle, and Meredith's observa
