Answer:

The crystallinity of cellulose is an inherent property that governs its mechanical properties, affinity for water, and accessibility to chemical reagents. Since the crystallinity is the result of interchain hydrogen bonding, changes in crystallinity reflect decreases or increases in this bonding.

Although water alone cannot break the interchain hydrogen bonds, decrystallization can be brought about by many reagents. The extent of decrystallization may vary from partial swelling to increase chemical accessibility to complete dissolution that permits reprecipitation and the formation of regenerated cellulose fibers such as rayon.

These reagents include concentrated sodium hydroxide; amines; metalloorganic complexes of copper, cadmium, and iron; quaternary ammonium bases; concentrated mineral acids (sulfuric, hydrochloric, phosphoric); concentrated salt solutions (beryllium, calcium, lithium, zinc); and mixtures of organic solvents.

An increase in crystallinity is unusual, but it does occur after hydrolysis of amorphous cellulose. The broken chains have greater freedom to form more highly organized structures.
