Popis: Cotton fibers swollen in both ethylenediamine and ZnCl 2 could be layered by the layer expansion technique, although the layer separations are much higher as compared to those normally obtained with raw cotton fibers. In spite of a lot of residual cellulose I, swelling by both these reagents does not preserve the bilateral structure existing in cotton and made more visible by partial mercerization in alkali metal hydroxides. This indicates that they produce an extensive and uniform swelling although the phenomenon is very much time dependent
