Scaling Up Hollow-Fibre Spinning: From Lab Fibres to Pilot Production

At a glance. Lab spinning proves a dope recipe; pilot spinning proves it can be made consistently in volume. The Tech Inc. Pilot Hollow Fibre Spinning Line controls dope and bore flow, air gap, bath temperature and take-up speed.

Variables that must be controlled

• Dope and bore-fluid flow and temperature.

• Air gap and humidity.

• Coagulation and rinse bath temperature.

• Draw ratio between spinneret and godets.

What the line delivers

Enough fibre for full-size modules, with recipes that transfer to production.

Frequently asked questions

Single or multi-spinneret? Single for development, multi for pilot output.

Dual-layer fibres? Yes, with a dual-layer spinneret.
