Equations are proposed for calculating the kinetics of the change in the degree of polymerization of cellulose in basic medium; they describe the experimental data with sufficiently high accuracy. The dependence of the rate constant of degradation of cellulose in mercerization on the concentration and temperature of the alkali and the content of low-molecular-weight fractions in the reaction mass...
Rigorous respect of the standard character and purity of the spinning solution, spinning bath parameters, and orientation draw ratio ensures obtaining a complex fibre homogeneous over the length. By varying the flow rate of viscose from the spinneret and disk rotation, it is possible to vary the fibre tension, strength, elongation, and shrinkage within wide limits and ensure a high capacity for uniform...
