Quick Answer: Velve fire-resistant yarn: meta-aramid (1313) and para-aramid (1414). For protective textiles and industrial use.

Fire-resistant yarn: key facts

  • Meta-aramid (1313) and para-aramid (1414) are high-temperature fibers used in protective and industrial textiles.
  • Fire-resistant yarns are selected for resistance to ignition, heat and flame spread; the right fiber depends on the standard and end use.
  • Velve supplies meta-aramid and para-aramid yarns/threads for protective clothing and technical textiles.

What to verify before sourcing

  • Request fiber content, construction and the relevant flame/heat test report for the exact product and batch.
  • Confirm wash/abrasion requirements, seam performance and the standard your finished garment must meet.
  • Do not rely on a generic “fireproof” claim; verify the test method and the finished assembly.

Fire-resistant yarn: standards and test methods to discuss

  • Finished garment standards (the applicable one depends on end use and market): EN ISO 11612 for heat and flame protective clothing, EN ISO 11611 for welding, IEC/EN 61482-2 for arc flash, and NFPA 2112 for US industrial FR clothing.
  • Material screening: limited flame spread (ISO 15025 / ASTM D6413), LOI (ISO 4589 / ASTM D2863), heat resistance, shrinkage and wash durability where relevant.
  • Arc/thermal performance: when the application requires it, ask for ATPV/ELIM or heat-transfer data for the exact finished assembly.

Meta-aramid vs para-aramid

  • Meta-aramid (1313): heat and flame resistance with textile comfort; common in FR workwear and protective layers.
  • Para-aramid (1414): high strength, modulus and cut/abrasion resistance; often blended for reinforcement.
  • Blends: meta/para blends and antistatic variants are common; confirm fiber content and the finished-garment standard.

Important: Velve supplies yarn/thread. Finished-garment certification belongs to the garment manufacturer; request the test report for the exact yarn, batch and standard before specifying.
