- Real-time acquisition and display the raw material tank pressure;
- Real-time display the flow of metering pump;
- Roller and metering pump frequency control.
Application
Application of Small Size Wet Spinning Machine
Wet spinning is the oldest of the five processes. The polymer is dissolved in a spinning solvent where it is extruded out through a spinneret submerged in a coagulation bath composed of nonsolvents. The coagulation bath causes the polymer to precipitate in fiber form.
Wet Spinning machine can be used in the teaching and research experiments of new fiber manufacturing, functional fiber development and raw material spinnability. Here are the features of this machine:
