Spinning coagulation bath device

Abstract

The invention discloses a spinning coagulation bath device, which belongs to the technical field of textile machinery. It includes a water tank (1), a water separation partition (8), and a bundle godet roller assembly (6). The water separation partition (8) is arranged in the water tank (1), so that the accommodation space inside the water tank (1) It is divided into a first accommodation space (17) and a second accommodation space (14) by a water dividing partition (8), and the bundle godet roller assembly (6) is arranged in the first accommodation space (17); the second The bottom of the accommodating space (14) is provided with a first through hole (18), and the second accommodating space (14) communicates with the outside world through the first through hole (18); 1) The top edge. The spinning coagulation bath device can ensure that the fluid in the coagulation bath is stable. In addition, the setting of the water divider (8) not only ensures that the water tank (1) can be completely filled with solvent, but also meets the gap requirements for cooling side blowing. .

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a spinning coagulation bath device. Background technique [0002] Dry jet wet spinning is both dry and wet spinning, which means that the spinning solution first passes through a dry layer, that is, the air layer, after being ejected through the spinneret micropores. Physical changes occur, and the water in the spinning solution evaporates rapidly. The filaments with dense, uniform and thin structure are formed, and then through the coagulation bath, the filaments are solidified into a filament structure with high density, smooth surface and no grooves through the process of bidirectional diffusion and phase separation of solvent and water. At present, dry-jet wet spinning has been widely used in the production of various fibers, enabling high-speed spinning. In order to pursue high fiber production, producers often want to increase the speed of the tow entering the co...

AI Technical Summary

Problems solved by technology

[0003] The coagulation bath tank in the existing production cannot be completely filled with solvent, resulting in too large blowing gap between the solvent liquid level and the spinneret, affecting the forming of the tow, and finally affecting the quality of the finished tow; In the bath water tank, in the actual production, due to the deep godet roller depth, it is difficult for workers to spin the tow; After falling into the coagulation bath, the tow cannot return to the tow with the water flow. The surface friction of the cluster godet roller made of stainless steel is relatively large, and the tension, tension and resistance of the final tow are relatively large, which makes it difficult for workers to form a tow.
