The considerable body of data made available by many electron microscopical investigations of wet-disintegrated regenerated cellulose has yielded a structural picture in all ways less satisfactory than that established for native celluloses (1). Generally micrographs of regenerated cellulose show a confusion between quasi-microfibrillar structure and ostensibly amorphous debris. Added to this uncertainty there exists some conflict in the literature, for example the somewhat indefinite structure observed by Hock (2) in wet-beaten Viscose Rayon contrasts markedly with the extraordinarily well defined microfibrils found by Ribi (3) in similar material.
