Description

Spinning solution filtering equipment for acetate fiber cloth production Technical Field The utility model relates to the technical field of spinning solution filtration, in particular to spinning solution filtration equipment for acetate fiber cloth production. Background The acetate fiber cloth is prepared with cellulose acetate extracted with wood pulp or cotton velvet as material, and through esterification reaction to produce cellulose acetate, dissolving in acetone to form spinning liquid, dry spinning to form continuous fiber, stretching, crimping and other physical treatment to strengthen the fiber strength, warping, weaving, dyeing and finishing to produce environment friendly fabric with silk luster, moisture absorption, ventilation and antistatic performance, and the production process needs precise control of esterification degree, solution concentration, spinning speed and other parameters to ensure stable product performance; the spinning solution for producing acetate fiber cloth is a viscous transparent liquid formed by taking cellulose acetate extracted from wood pulp or cotton velvet as a raw material, generating cellulose acetate through esterification reaction and then dissolving the cellulose acetate in an acetone solvent, wherein the preparation needs to strictly control the concentration of acetic acid, the esterification degree, the concentration of solution and the temperature so as to ensure that the viscosity of the spinning solution is uniform and free from impurities, and the cellulose acetate fiber is extruded into fibers through a spinneret plate in the subsequent dry spinning or wet spinning, so that the strength and the luster of the fibers, the moisture absorption, the air permeability, the antistatic property and the like of the finished product cloth are directly influenced.
