DFR Wool Fabric

Durable FR Wool: Nature’s Ultimate Shield Against Fire and Heat

Wool is nature's most sophisticated technical fiber. Our Durable Naturally Flame Retardant Wool fabrics maximize this inherent capability. With a high natural nitrogen and moisture content, wool is difficult to ignite and self-extinguishes rapidly. Unlike synthetics that melt, or cotton that burns, FR Wool forms a stable insulating char. We enhance this natural resistance with durable treatments to meet the strictest aviation and industrial standards. It provides a unique combination of low smoke toxicity, superior thermal insulation, and exceptional breathability, making it irreplaceable in enclosed transit environments and hot metal industries.

Key Features

• Naturally Self-Extinguishing: Wool has a high Limiting Oxygen Index (LOI). It stops burning as soon as the ignition source is removed.
• Molten Metal Splash Resistance: It is the superior choice for protection against molten aluminum and cryolite splashes, where other fabrics fail or stick to the skin.
• Low Smoke & Toxicity: In a fire, wool produces significantly less smoke and toxic gas compared to synthetic fibers, crucial for survival in aircraft and trains.
• Thermo-Physiological Comfort: Wool naturally regulates body temperature and manages moisture, keeping the wearer cool in heat and warm in cold.

International Standards Compliance

Our FR Wool fabrics are certified to meet the highest safety codes for transport and heavy industry:

• FAR 25.853 / JAR 25.853: The gold standard for Flammability of Aircraft Seat Cushions and Interiors (Vertical Burn Test).
• EN ISO 11612: Protective clothing against heat and flame (Specifically Codes D1/D2 for Molten Aluminum Splash).
• EN 45545-2: Fire protection on railway vehicles (Requirements for seats and curtains).
• BS 5852: Methods of test for assessment of the ignitability of upholstered seating (Crib 5/Source 7).

Applications

Sector	Typical Use Cases	Why FR Wool?
Aviation & Aerospace	Seat Covers, Carpet, Curtains	Meets FAR 25.853; low smoke emission is critical for cabin safety.
