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 develop and modify extrusion processes to enhance fiber properties and achieve new functional cores and surfaces.

In applied projects we develop, in collaboration with industry partners, fibers that enhance the quality of life. Our specialties lie in fibers for lightweight structures, liquid-filled fibers, flame retardant fibers, and fibers from renewable sources.
