187.~ Hydration and/or gelatinization


DEFINITION

Classification: 162/187

(under subclass 100) Processes and products in which the cellulosic fibers are chemically or physicochemically united with water to produce a hydrated or partially gelatinized fiber.

(1) Note. The water is usually associated with the fibers by being agitated therewith, as in a beater or Jordan. The fibers may also be subjected to mechanical comminution simultaneously with the hydration. In all processes in which fibers are treated in suspension or in the presence of water some hydration may take place. Processes of this character are not classified herein unless the hydration or gelatinization is distinctly disclosed.
