Scaling Hollow Fibre Spinning from Pilot to Production

At a glance. A Tech Inc. Commercial Hollow Fibre Membrane Spinning Line runs several metered spinnerets in parallel, so the pilot recipe can be kept while output multiplies.

What changes at production scale

• Dope supply: larger vessels, continuous degassing and filtration.

• Metering: one gear pump per spinneret, so every fibre gets the same flow.

• Baths: longer coagulation and washing to match higher speeds.

• Winding: several positions with tension control.

What to specify

• Fibre OD and ID, and target output per day.

• Polymer and solvent system.

• Number of positions now and later.
