Hydrolysates of fibers swollen in various intracrystalline swelling agents were ball- milled for separate periods. These samples containing different proportions of cellulose I (C I) Cellulose II (C II) and amorphous (Am) phases were subjected to a mild hy drolysis, and their recrystallization behavior was studied by x-ray diffraction methods. Recrystallization into C I occurs only by nucleation, whereas recrystallization into C II is also caused by accretion of the long disordered molecular segments severed from crystallites.
