Wet spinning forming device

Abstract

The invention discloses a wet spinning forming device. The wet spinning forming device comprises a solidification batch and is characterized in that a baffle is arranged on the front portion and / or the rear portion inside a solidification bath body, two or more than two circular holes are evenly distributed in the baffle, the baffle is connected with the solidification bath body to form independent space, the bottom of the independent space of the front portion of the bath body and the bottom of the middle of the solidification bath body are respectively provided with a solidification bath liquid inlet pipe, and the tail portion of the solidification bath body and the bottom of the middle of the solidification bath body are respectively provided with a solidification bath liquid returning pipe. Flowing of solidification bath liquid in the solidification batch is controlled to enable the concentration and the temperature of the solidification bath liquid in the solidification bath to be homogeneous, the monofilament breakage caused by turbulent flow of the solidification bath liquid or pelagic silk crumbs generated by retention of the solidification bath liquid is prevented from being generated, and the fibers with the good quality can be manufactured.

Description

technical field [0001] The invention relates to a chemical fiber spinning machine. Background technique [0002] The production methods of chemical fibers mainly include melt spinning and solution spinning. Among them, solution spinning can be divided into wet spinning and dry spinning according to different coagulation conditions. Wet spinning is to dissolve the fiber-forming polymer in a solvent to make a spinning solution. The spinning solution is sprayed from the spinneret and then enters the coagulation bath. Due to the diffusion of the solvent in the spinning solution and the coagulation agent to the mucus Infiltrating into the filament stream, so that the filament stream solidifies into filaments. Now the chemical fibers that adopt wet spinning in the world mainly include acrylic fiber, spandex, vinylon, viscose fiber and so on. Wet spinning mainly includes spinning dope preparation, pre-spinning preparation, spinning, oiling, winding, etc. The preparation of spin...

AI Technical Summary

Problems solved by technology

The disadvantage is that there are turbulent flow of the coagulation bath near the spinneret, uneven concentration of the coagulation bath, and uneven temperature, which will cause the monofilament breakage of the coagulation filament, and the concentration of the coagulation bath in the coagulation bath will increase with the increase of the fiber. Spinning will gradually decrease, and the fiber ejection will cause the fluid in the tank to appear in an unstable and disturbed state, resulting in poor uniformity of the fiber after spinning, making it difficult to control the strength and quality of the fiber
