Wool has a naturally scaly surface, and because its fibers are not perfectly aligned, they tend to hook onto each other when they come into contact. Warm and humid conditions amplify this effect, causing the wool to felt. To prevent this, wool must be treated.
The conventional process used until now smooths these scales and coats the fibers with a chlorine-based film to make them machine washable. However, this process releases significant amounts of AOX pollutants, contributing to environmental pollution directly linked to wool fibers.
EXP stands for “EX-Pollution”, meaning the avoidance of pollutants during the anti-felting treatment process. Developed by our spinning partner Südwolle Group, EXP is a groundbreaking process that allows wool to remain machine washable without the use of chlorine. Any microparticles that may detach during washing and enter the water cycle are fully biodegradable.
