Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coagulation baths, in particular to a coagulation bath used for wet spinning. Background Art
[0002] One of the main chemical fiber spinning methods, referred to as wet spinning, involves circulating the spinning solution through a pipe to the spinning machine, where it is metered by a metering pump and then passed through a candle filter and connecting tubes before entering the spinneret (cap). The spinneret is typically made of a gold-platinum alloy or a tantalum alloy. The spinneret features regularly spaced holes with a diameter of 0.05 to 0.08 mm. A thin stream of solution is extruded from the holes and enters a coagulation bath. The solvent in the solution diffuses into the coagulation bath, and the coagulant permeates the stream, causing the solution to reach a critical concentration, where it precipitates and forms fibers. Conventional coagulation baths typically place the coagulation solution directly into the bath. This can cause the solution concentration to fluctuate over time, significantly impacting subsequent spinning. Furthermore, spinnerets are often fixed, making it impossible to adjust the solution according to production needs. Therefore, we propose a coagulation bath for wet spinning. Utility Model Content
[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a coagulation bath for wet spinning. An electric telescopic rod is used to adjust the height of the spinneret. At the same time, an appropriate number of spinnerets can be installed according to different spinning requirements to improve work efficiency. The circulating coagulation liquid can also be adjusted in concentration in real time to prevent concentration changes from affecting subsequent spinning effects, which can effectively solve the problems in the background technology.
