Wool in Carpets and Technical Textiles
topic
Carpet applications (30% of wool use): coarser wool (30-40 μm) in tufted, woven, and needlepunch carpets providing resilience (rapid recovery from compression), soil resistance (scales trap dirt in surface preventing penetration), flame resistance (LOI 25%, slow burning, low smoke/toxic gas generation), acoustic insulation (NRC 0.40-0.55), and durability (20-25 year residential life). Often blended with nylon (80:20 wool:nylon) for enhanced durability. Technical textiles: insulation (building, automotive), geotextiles (biodegradable erosion control), composites (wool-polymer composites for automotive interiors), and filtration media.
Role
Wool carpets command premium residential and commercial markets where natural aesthetics, comfort (warm, soft feel), environmental benefits (biodegradable, low VOC emissions, carbon negative lifecycle), and performance justify 2-5× cost premium over nylon, with 200,000+ tonnes annual wool carpet consumption.
