Abstract
The existence of optimality criteria for viscose and spinning bath compositions is advanced as a working hypothesis. The degree of preparation of viscose for spinning is expediently characterized not only by the ripeness index and viscosity, but also by the chemical composition: the ratio of sodium trithiocarbonate (TTC)/NaOHfr. A ratio of ∼2.0-2.1 should be considered optimum. Specific conductivity on the level of 32-33 S·m−1 is the criterion of spinning bath activity.
