Is wool fire resistant?

Q: I’m a workwear designer and I need to know each type of fabric feature for my work, I’d like to know if is wool fire resistant

– Vassia Roditou

A: Yes, wool is considered naturally fire-resistant. It has several characteristics that make it less likely to burn compared to many other fabrics:

  1. Higher Ignition Temperature: Wool requires a higher level of heat to ignite compared to many other textiles.
  2. Self-extinguishing: If wool does catch fire, it usually self-extinguishes once the source of the flame is removed.
  3. Lower Rate of Flame Spread: When wool does catch fire, it tends to burn slowly, smoldering in a manner that gives people more time to respond.
  4. Less Melting: Unlike some synthetic materials, wool doesn’t melt, which can reduce the risk of severe burns.

Despite these characteristics, though, it’s important to note that wool can still catch fire under certain conditions. It’s not completely fireproof. Also, if wool is treated with certain chemicals or combined with other, more flammable materials, its fire resistance might be affected.

For situations where fire safety is a concern, it’s always best to rely on materials that have been specifically designed and treated for fire resistance, and that meet the necessary safety standards.
