Wet Spinning in the Lab: Making Fibres That Cannot Be Melt-Spun

At a glance. In wet spinning, a polymer solution is pumped through a spinneret into a bath where it solidifies, then drawn and wound. The Tech Inc. Lab Wet Spinning Machine does this on a bench.

Controls that matter

• Dope flow from a metering pump.

• Bath composition and temperature.

• Draw ratio set by godet speeds.

• Take-up speed at the winder.

Fibres made this way

Regenerated cellulose, acrylic precursors for carbon fibre, chitosan and alginate, and graphene oxide fibres.

Frequently asked questions

How much dope is needed? A few millilitres for first trials.

Can it make hollow fibres? For membranes, see our hollow-fibre spinning machines.
