Fringe micellar theory

The spatial configurations proposed by Kratky [38] and Mark [39] repeat in principle the basic idea of the fringe micellar theory, according to which long cellulose chains lie lengthwise through the crystal and amorphous phases form the fibre (Fig. 80).

The crystallinities of cellulose are obtained from X-ray diffraction techniques, which give the most direct results, although their interpretation and evaluation is still under discussion and widely based on convenience. On the basis of the two-phase fringed-micellar structure, Hermans and Weidinger derived a theory on the proportionality of the intensity or amplitude of scattering from the amorphous and...
