CELLULOSE DOPE AND PROCESS FOR PRODUCING THE SAME

摘要

A cellulose dope comprising an aqueous caustic soda solution and a cellulose dissolved in the solution, characterized in that the concentration of caustic soda (CNa) is 6.5 to 11 wt.%, the cellulose content (CC) is 4 to 12 wt.%, and zero-shear viscosity of the cellulose dope ( eta 0), the cellulose content (CC), and the viscosity-average degree of polymerization of the cellulose satisfy the following relationship (1): eta 0 = kCC x DPC

. In the relationship, eta 0 represents zero-shear viscosity of the cellulose dope (mPa.s); CC represents cellulose content of the cellulose dope (wt.%) DPC represents viscosity-average degree of polymerization of the cellulose in cellulose dope; K = 3.9 x 10<-11>; 5
