Project

Closed-loop recycling of wool/synthetic blend textiles

Textile production of today almost exclusively uses virgin raw materials. A lot of the textiles, especially clothing, are only used for a short period of time whereafter they become waste. This project aims to close the loop, by …

Wet spinning

Wet spinning is a manufacturing process used to produce fibers from polymer solutions by extruding them into a coagulation bath, where the polymer solidifies into fibers. This method is called "wet" spinning because the process in…

Development of filament and staple fibers

Man-made fibers produced using solution spinning are collected and processed as filament or staple fibers depending on the desired application. RISE has equipment and knowledge to develop these two types of fibers that can be furt…

Development of dopes for wet and air-gap spinning

An essential step in solution spinning is the development of spinning dopes (polymer solutions) with optimal properties. Precise control over dope properties is essential for ensuring proper extrusion and coagulation, thereby layi…

Air-gap spinning

Air-gap (dry-jet wet) spinning is a method used for man-made fiber production. In this method, a polymer solution is extruded through a spinneret and travels through an air gap before entering the coagulation bath. Air gap allows …

Solution spinning of man-made fibers

Within our expertise in solution spinning, both wet and air-gap (dry-jet wet) spinning, we develop man-made fibers from polymers that are either non-thermoplastic or sensitive to temperature. This method is particularly useful for…
