According to our series of studies, a new theory on the spinning mechanism of modified viscose has been proposed.
In this paper, the courses of coagulation, regeneration and stretching of modified viscose were investigated in details with the following results:
(1) The degree of gel swelling of the spinning filaments lowers as the length of spin bath immersion is increased and come up to the equilibrium degree at a certain length of immersion.
(2) The residual γ-value of the spinning filaments decreases as the length of spin bath immersion is increased.
(3) At a certain point of the longer immersion length, that is, the lower residual γ-value than that of the equilibrium gel swelling, the stretchability rises to maximum and the highest tenacity is obtained.
Based on these facts, the mechanism of the fiber formation of modified viscose is discussed applying the theory of rubber elasticity.
