Wet spinning

Under wet spinning is understood to mean the production of fibers from polymer solutions that are injected (mixture) into a precipitation bath with a further solvent. The polymer precipitates and one or more filaments can be wound up as fibers after several further processing steps. The wet spinning process is used for polymers that either cannot be melted, are very temperature-sensitive, or can only be processed in special solvent systems.

This process is used, for example, in the manufacture of hollow fibers for membrane technology and in the manufacture of p- aramid fibers as well as viscose , cupro , lyocell and triacetate fibers .
