Thermodynamically, fiber formation in wet spinning or dry-jet wet spinning occurs through the process of solidifying the polymer solution extrudate through the outward diffusion of the solvent and the inward diffusion of the non-solvent.
It was found that the outward diffusion rate of the solvent and inward diffusion rate of the nonsolvent increase as the coagulation bath temperature is increased for both wet spinning and dry-jet wet spinning of the acrylic fibers.

The microfiber mixtures can be converted into fibers by wet spinning, gel spinning, melt spinning, melt blowing, or extrusion.
The company's wet spinning systems have solution pumped through the spinnerettes by spinning pumps directly into the coagulation bath, where solidification occurs.
Therefore, it is a significant and challenging task to improve the mechanical properties of the PI fibers fabricated by two-step wet spinning technology.
