Pulps with low cellulose viscosity refine faster, so the refiner operator should be aware of changes in the pulp viscosity.

Pulps with low cellulose viscosity refine faster, so the refiner operator should be aware of changes in the pulp viscosity. Correct Answer True

The level of refining can be followed with Simons in 1950 stain of fibers observed through a microscope. Even without staining, refining can be followed qualitatively with microscopic observation.
