3.5 Recycling of Fibre Blends: Progress in Closed-Loop and Alternative Technologies
At present, many blended fibre materials are generally suitable for open-loop recycling systems.
Requirements for processes designed to recycle blended materials must be capable of handling
lower grade materials, applying treatments to separate or selectively dissolve blended constituents,
and removing impurities such as finishing chemicals and dyes. With ongoing developments in
fibre-to-fibre recycling processes of prevalent textile materials, concurrent progress in closed-loop
recycling of fibre blends will facilitate the transition to circular systems. Table 12 provides
examples of current commercial, patented, or processes under development for recycling of fibre
blends.
