Our 40S/2 royal‑blue meta‑aramid sewing thread is manufactured from 100% meta‑aramid staple fiber with inherent flame‑retardant property, no chemical finishing added. The rich royal‑blue color is well‑matched for dark‑toned firefighting uniforms, FR workwear and protective apparel. This industrial sewing thread performs non‑melting and non‑dripping under flame condition, retaining stable seam strength after repeated laundering, and conforms to mainstream European PPE performance standards.
