Why should Lyocell fibers pass through a period of air before entering the solidarity bath?

The dry and wet method can also be used for the entire macromolecular chain in the air, which is conducive to the improvement of strength

How to filter the spinning fluid?Seeking a high -finger point

1) Application of high concentration and low viscosity.The spinning area and the coagulation range spacing, which affects the polymer to the nozzle before coagulating before the extension point.The silk is very tight;
3) Compared with wet spinning, Jet-WET spinning has a relatively good compact molecular discharge.
In short, the effect of stretching in the air gap

Spraying the spinning fluid directly in the solidarity bath will cause the spinning pressure to be too high to not spin the wire, so it must pass through a period of air gap.

Go to see the difference between wet and wet spinning.

Coormination in advance is conducive to improving the mechanical properties of fiber, the benefits of dry spraying and wet texture
