Our 40S/3 red meta‑aramid sewing thread is produced from 100% meta‑aramid staple fiber with inherent flame‑retardant performance, without additional chemical flame‑retardant coating. The vivid red color fits fire service uniforms, FR safety workwear and special protective apparel. This industrial sewing thread features non‑melting and non‑dripping properties when exposed to flame.
