Problems solved by technology

In the existing dry spinning process, the solvent volatilization speed is slow, so the spinning speed cannot be effectively improved, and the working efficiency of dry spinning is lower than that of wet spinning. In addition, the collection of solvent is not complete enough, resulting in greater environmental pollution. , which limits the application of dry spinning

Abstract

The invention provides an anti-pollution dry spinning device. The anti-pollution dry spinning device comprises a spinning solution storing tank. The anti-pollution dry spinning device is characterized in that a spinning pump is stored in the spinning solution storing tank and is connected with a spinneret plate mounted in a processional road through a pipeline, and the lower part of the processional road is connected with a winding drum through a yarn guide disc; and the processional road is provided with an air inlet and an air outlet, the air inlet is connected with a hot gas supply device through the pipeline, and the air outlet is connected with a volatile solvent purifying device through the pipeline. According to the anti-pollution dry spinning device, the volatilization of a solvent can be accelerated, so that the spinning speed is increased; and meanwhile, the solvent can be effectively processed, so that environmental pollution is avoided.

Description

[0001] Technical field: [0002] The invention relates to an anti-pollution dry spinning device, which belongs to the technical field of chemical fiber spinning. [0003] Background technique: [0004] Both dry spinning and wet spinning are commonly used methods for polypropylene spinning. Different from wet spinning, during dry spinning, the thin stream of spinning liquid pressed out from the capillary of the spinneret does not enter the coagulation bath, but enters the spinning shaft. Through the action of the hot air flow in the tunnel, the solvent in the thin stream of the stock solution is quickly volatilized, and the volatilized solvent vapor is taken away by the hot air flow. The stock solution solidifies while gradually removing the solvent, and elongates and becomes thinner under the action of winding tension to form nascent fibers. [0005] There are some similarities between dry spinning and melt spinning. Both of them are solidified by making the viscosity of poly...
