Spinnerets & needles
The islands-in-the-sea spinneret forms composite fibers from three or more materials. Multiple channels bring polymers with different properties into one fiber structure. When N components are spun together, selectively removing one or more components after spinning can increase porosity and specific surface area.
It can produce composite fibers with a cable-like cross-section.
