Application
Application of Dry Jet Wet Spinning Machine
A variant of wet spinning is dry jet wet spinning, which is called dry-wet spinning for short. It is a chemical fiber spinning method which combines the characteristics of dry spinning and wet spinning. This is a new spinning method developed in the 1960s.
Dry Jet Wet Spinning machine has been used in the production of polyacrylonitrile fiber, aromatic polyamide fiber, polybenzimidazole fiber, etc.
The spinning speed of dry jet wet spinning can reach 600 ~ 1200 m/min, which is much higher than that of wet spinning. And the spinneret with larger aperture (φ=0.15 ~ 0.3 mm) can be used. However, the concentration and viscosity of the spinning solution can be as high as that of dry spinning. What’s more, the structure formation process of the fiber can be controlled effectively by dry jet wet spinning. In dry spinning, the solidification speed of liquid flow is often very slow due to the limit of solvent evaporation speed. In dry-wet spinning, the flow of liquid (fiber) being drawn enters the coagulating bath. And the solidification rate and fiber structure can be changed over a wide range by adjusting the composition and temperature of the coagulating bath.
