Description

Oval dry spinning channel

Technical Field

The utility model relates to the technical field of spinning equipment, in particular to an elliptical dry spinning channel.

Background

The channel for dry spinning is a heat and mass transfer place for evaporation and drying, and is also a solvent recovery place. The hot gas in the channel is a mixed gas composed of solvent steam, nitrogen and the like, and is essentially a dryer, and the thicker solvent in the stock solution is evaporated by using the lower solvent concentration in the channel gas and then taken away for recovery. When the concentration of the solvent in the stock solution is reduced to a certain extent, the polymer solidifies into a strand. The filament forming process is also a solvent volatilization and recovery process, and the solvent volatilization condition is an important condition affecting the spinning condition and the quality index of the finished product.

Most of the existing spinning channels are provided with unidirectional air blowing in rectangular channels, and the yarns are easy to break due to uneven volatilization of solvents in the advancing process, and are poor in elongation resilience and uneven in evenness. The unidirectional blowing of the rectangular channel is easy to generate vortex and uneven wind speed, which causes vibration and fluttering of the yarn and causes yarn doubling and uneven yarn doubling of the primary yarn. The air speed is too small, the solidification speed of the silk is reduced, the solvent of the silk is not volatilized, the density of the silk is small, and the spinning speed cannot be improved.
