Fibre Spinning Line – Pilot


The FSL 4 ™ is a state of the art pilot-scale fibre spinning line designed for optimal production of hollow fibres through a phase transformation process. This pilot-scale spinning line can be used with different combinations of polymers and solvents.

A single or double skin membrane can be formed depending on predefined production settings. The lumen is produced when a mixture of solvent and water is introduced in a spinneret.

The spongiform semipermeable texture is formed when the polymer mix hits the water surface in the coagulation bath. The fibre is then washed, dried, possibly crimped to be finally bundled and cut to length.
