CELLULOSE DOPE AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>A cellulose dope comprising an aqueous caustic soda solution and a cellulose dissolved in the solution, characterized in that the concentration of causti c soda (CNa) is 6.5 to 11 wt.%, the cellulose content (CC) is 4 to 12 wt.%, an d 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 = kCCm .times. DPCp. 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 .times. 10-11; 5 <= m <= 7; and 3 <= p < = 4.</p> |
