CELLULOSE DOPE AND PROCESS FOR PRODUCING THE SAME

摘要

Disclosed is a cellulose dope comprising an aqueous sodium hydroxide solution and cellulose dissolved in the solution, wherein the cellulose dope has a sodium hydroxide concentration (CNa) of from 6.5 to 11 % by weight and a cellulose content (Cc) of from 4 to 12 % by weight, and wherein the zero-shear viscosity ( eta 0) and the cellulose content (Cc) of the cellulose dope and the viscosity average degree of polymerization (DPc) of the cellulose in the cellulose dope satisfy the following formula (1): eta 0 = kCc x DPc

wherein: eta 0 represents the zero-shear viscosity (mPa.s) of the cellulose dope, Cc represents the cellulose content (% by weight) of the cellulose dope, DPc represents the viscosity average degree of polymerization of the cellulose in the cellulose dope, k = 3.9 x 10<-11>, m is a number of from 5 to 7, and p is a number of from 3 to 4. Also disclosed is a method for producing this cellulose dope.
