Structured Fibers

We develop and research structured fibers, applying a combination of polymers and additives. We handle fundamental questions regarding fiber molecular structure and morphology, from the nanoscale to the microscale. And we modify extrusion processes to enhance fiber properties and to achieve new functional cores and surfaces.

In applied projects we develop fibers that enhance the quality of life, in collaboration with industry partners. Our specialties lie in electrically and optically conductive fibers, liquid-filled fibers, flame retardant fibers and fibers from renewable resources.
