Abstract
Disclosed is a continuous preparation method of cellulose fibers, in which a forming tension of 0.1 to 1.9 cN/dtex is applied to a fine solution stream obtained by extrusion through a spinneret plate and air gap cooling, then the fine solution stream is fed into a coagulating bath at a speed of 80 to 1000 m/min, a traction tension of 0.075 to 1.5 cN/dtex is continued to be applied to washed fibers in a water washing system behind the coagulating bath, and finally, the washed fibers are fed into a post-treatment system for continuous and efficient spinning of finished fibers at a speed of 80 to 1000 m/min.
