10.4 Manufacturing process variables

The control over the supramolecular structure in fibers is exerted by optimizing the
following interrelated variables in the manufacturing process: the average degree of
polymerization and molecular weight distribution in the pulp, the profile of dope
rheology as function of cellulose concentration and molecular weight distribution,
the length-to-diameter (L/D) ratio in the spinneret orifices, and the degree of stretch
