100% Meta-aramid sewing thread is made of meta-aramid staple fiber through ring spinning. Meta-aramid is a type of aromatic polyamide fiber (aramid fibers), the full name is polyisophthalic Meta-phenylenediamide fiber, the English name is meta-aramid or PMIA for short, we also call it aramid 1313, the main raw materials of
Nomex,
Conex, Tametar ,meta-aramid are isophthaloyl chloride (IPC) and meta-phenylenediamine (MPD). The 100% meta-aramid sewing thread process is divided into: Blowroom-Carding room--Pre-drawing--Strip drawing--Combing--First drawing--Second drawing--Roving--Spinning yarn--Winding.
100% Meta-aramid sewing thread has excellent inherent fire resistance, good thermal stability, high strength, corrosion resistance, chemical resistance, radiation resistance, long service life and other advantages. It is mainly used for sewing fire rescue suits, flight suits, police uniforms etc. Flame retardant and high temperature resistant 100% meta aramid sewing thread produced by Shanghai Shenghe Textile Technology Co., Ltd, 100% meta-aramid sewing thread is a flame-retardant material with good flexibility, low thermal conductivity, corrosion resistance, high temperature resistance, and non-flammability. It is mainly used for sewing fire-fighting suits, such as ( firefighting combat uniforms/firefighting evasive clothing/firefighting gloves), military clothing sewing, such as (tactical gloves/special police gloves/air force gloves, sewing of aviation supplies, such as (aircraft seat fireproof layer/aircraft seat cover/aviation blanket), petrochemical product sewing, such as (fire blanket for electric welding construction/petroleum exploration cable reinforcement material), sewing of steel smelting clothing, such as (furnace fitter clothing, gloves), sewing of shipyard supplies.
