Popis:	The variations in the layered morphology of cotton fibers treated identically with LiOH, NaOH and KOH may be traced to differences produced by the swelling agents at the ultrastructural level. X-ray data also supports this presumption. The persistence of bilateral structure in the layered section of the alkali swollen fibers is decided not only by the quantity of residual lattice but also by the nature of crystalline order present in the residual lattice. Absence of bilteral structure after swelling is related to higher conversion to cellulose II in addition to higher amorphous content
