LEEDS – New research claims to demonstrate a rapid, chlorine-free method for removing the covalently bound lipid layer from wool fibres – a breakthrough that could improve wet processing across the global wool supply chain.

The new treatment also claims to eliminate the formation of absorbable organic halides (AOX) – a key environmental concern with conventional chlorination processes.
