Carpet Fibre Burn Tests

Carpet fiber burn tests are conducted to determine the behavior of different types of carpet fibers when exposed to fire. These tests help assess the flammability, ignition, and burning characteristics of carpet materials. The results of carpet fiber burn tests can vary depending on the type of fiber being tested. Here are the general results for some common types of carpet fibers:

  1. Nylon: Nylon fibers have good fire resistance properties. They tend to melt and shrink away from the flame when exposed to fire. They have a self-extinguishing property, meaning they stop burning once the flame is removed.
  2. Polyester: Polyester fibers are relatively flammable compared to nylon. They melt and shrink when exposed to fire but can continue to burn. Polyester fibers have a lower melting point and can leave behind residue when burned.
  3. Olefin (Polypropylene): Olefin fibers have low flammability and are often used in flame-resistant carpets. They have a high melting point and tend to shrink away from the flame. Once the flame is removed, they self-extinguish.
  4. Wool: Wool fibers are naturally flame-resistant. They have a higher ignition temperature compared to synthetic fibers. Wool tends to smolder when exposed to fire and can self-extinguish. It produces less smoke and toxic gases compared to synthetic fibers.
  5. Acrylic: Acrylic fibers have good flame resistance properties. They tend to melt and shrink away from the flame when exposed to fire. Acrylic carpets have a self-extinguishing property and produce minimal smoke and toxic gases.

It’s important to note that the specific performance of carpet fibers in burn tests can also depend on the construction and composition of the carpet, such as the backing material and any applied flame-retardant treatments. Additionally, the results of burn tests may vary based on the specific testing standards and conditions used in the evaluation.
