What is "Wet Spinning" - Definition & Explanation

In wet spinning, the polymer used to form the fibre is dissolved in solution. The solution is forced under pressure through an opening into a liquid bath in which the polymer is insoluble. As the solvent is dissipated in the bath, the fibre forms. Wet spinning produces rayon, acrylic, and modacrylic. Chemicals used in wet spinning may include acids, alkalis, reducing/oxidizing agents and bleaches
In the wet spinning process, the polymer solution (also known as "dope") is spun into a spin bath containing a liquid chosen for its ability to extract the solvent from the dope.
