STUDY ON SPINNING MECHANISM OF VISCOSE

In order to investigate the internal structure of viscose as a basic study on spinning mechanism of viscose, the structural viscosity was measured by varying the amount of the consumed carbon disulfide to make viscose, cellulose concentration, total alkali concentration in viscose and the degree of polymerization of cellulose. The internal structure of viscose should be considered rather as a concentrated solution of polymer than as a polyelectrrolyte solution of cellulose xanthate molecule in our experiments.In this report the effects of the factors, influencing upon the character of polyelectrolyte, such as the amount of the consumed carbon disulfide and ripening standard, on the internal structure of viscose are regarded as of secondary significance. It became clear in our studies that the factors influencing on the character of the concentrated solution, i.e. total alkali concentration, cellulose concentration and the degree of polymerization influencing on the interaction of polymerchain, changed the internal structure of viscose.
