Wool has a scaly surface, and since its fibers aren't arranged uniformly, they catch on each other when they come into contact. A warm, humid environment amplifies this effect and causes the wool to felt. Wool is treated to prevent this from happening.
The conventional process used until now involves smoothing these scales, then coating the wool fibers with a chlorine-resistant wash film. A significant amount of AOX pollutants is released during this process, causing environmental pollution directly attributable to the wool fibers.
EXP stands for "EX-Pollution", meaning the elimination of pollutants during the anti-felting treatment process. EXP is a revolutionary new process developed by our spinner Schoeller Spinning Group that allows wool to remain machine washable without the use of chlorine. Any microparticles that may detach during washing and enter the global water cycle are completely biodegradable.
