Camira launches non-halogenated flame retardant treatment for wool fabrics for public transport applications. The treatment can achieve the EU railway standard strictest heat, smoke release and smoke toxicity criteria (EN 45545(R21)-HL3) by enhancing wool’s natural fire resistance, which results from its moisture and nitrogen content. By enhancing charring, the treatment slows burning and minimising smoke release. Wet bath application reduces water and energy use, CO2 and ammonia emissions and provides a durable, wear resistant treatment.
