Meta aramid yarn

100% meta-aramid yarn is made from meta-aramid staple fiber through ring spinning. Meta-aramid is a type of aromatic polyamide fiber (aramid fibers), the full name is polyisophthalic Meta -phenylenediamine fiber, the English name meta-aramid is abbreviated as PMIA, we also call it aramid 1313, Nomex , Conex , Tametar. The main raw materials of meta-aramid are isophthaloyl chloride (IPC) and meta-phen ylenediamine (MPD), 100% meta-aramid the technological process of aramid yarn is divided into: Blow room - Carding - Pre-drawing - Strip and winding - Combing - First draw - Second draw - Roving - Spun yarn - Winding.

100% meta-aramid yarn has suitable textile processing properties, the fabric woven from 100% meta-aramid yarn has excellent inherent fire resistance, good thermal stability, high strength, light and soft fabric, good strength, good heat insulation effect, corrosion resistance, chemical environment resistance, and radiation resistance. With the advantages of good performance and long service life, it is mainly used in fire rescue suits, flight suits, police uniforms etc. The flame-retardant, high-temperature-resistant and heat- insulating 100% meta-aramid yarn produced by Shanghai Shenghe Textile Technology Co., Ltd. is a heat-insulating material with good flexibility, low thermal conductivity, corrosion resistance, high temperature resistance, and non-flammability. Widely used in firefighting (fire combat clothing cloth/firefighting fire retardant cloth/firefighting gloves cloth), military (tactical gloves cloth/SWAT gloves cloth/air force gloves cloth), aviation (aircraft seat fire barrier cloth/aircraft Seat cover cloth/aviation blanket), petrochemical industry (fire blanket for electric welding construction/petroleum exploration cable reinforcement material), steel smelting (furnace fitter clothing, cloth for gloves), shipyard (fire insulation blanket for electric welding construction) and other industries.

Performance characteristics

1. 100% meta-aramid spun yarn , bright color, variety, yarn size is even, very good yarn strength.
2. 100% meta-aramid spun yarn  is non-flammable, non-melting, non-heat-shrinkable, non-thermally cracked, and has no droplet.
3. Heat insulation and temperature resistance: excellent heat resistance and heat resistance performance, can be used for a long time at a relatively high temperature (≤260°C), is difficult to burn under an open flame, and will extinguish without flame.
4. Corrosion resistance: good chemical properties, resistant to various acid and alkali solvents, and can be used in harsh corrosive media.
5. Flame retardant and heat insulation: excellent heat insulation performance, low thermal conductivity, good heat insulation effect.  It has high flame retardancy, oxygen index ≥ 28%.
6. Excellent thermal stability: no softening and shrinkage, no melting drops, it is a quasi-non-combustible product. Good heat insulation effect, good corrosion resistance, chemical environment resistance, and radiation resistance.

Meta aramid yarn applications

1. Protective clothing: For example, high-temperature work clothes, firefighting suits, combat suits, welding suits, fire-resistant gloves.
2. For flame-retardant decorative materials: For example, flame-retardant and heat-resistant curtains,  seat covers of automobiles, motor vehicles, aircraft, and other flame-retardant and heat-resistant decorative products.
3. Filter material: For example, high-temperature gas/solid materials, flame retardant and heat insulation for automobiles and buildings, and thermal insulation in high-temperature environments.
4. Heat-insulating materials, fireproof, anti-welding spark materials, fire escape blankets, car seat inner cladding, sound insulation, interior decoration, etc.
