Meta Aramid Thread – Premium 1313 Meta Aramid Sewing Thread for Flame Retardant & High-Temperature Applications
Meta Aramid Thread, also known as 1313 Meta Aramid thread (or meta-aramid sewing thread), is a high-performance sewing thread engineered for applications where flame resistance and thermal protection are critical. Made from 100% meta-aramid fiber (PMIA, poly-m-phenylene isophthalamide), this 1313 aramid sewing thread delivers inherent flame retardancy that is molecularly built into the fiber structure – it cannot be washed out, worn off, or diminished over time. Whether you search for “meta aramid thread” or “1313 meta aramid thread,” you are looking for the same premium flame-retardant sewing solution trusted by professionals in firefighting gear, protective clothing, military combat suits, and high-temperature industrial textiles.
What Makes 1313 Meta Aramid Thread Exceptional?
Inherent Flame Retardancy: 1313 Meta Aramid thread has a limiting oxygen index (LOI) greater than 28% – well above the 21% oxygen concentration in air. This means the fiber will not sustain combustion in air, does not melt or drip, and is self-extinguishing when removed from the flame source. The flame resistance is inherent to the molecular structure and lasts the lifetime of the thread.
Superior Heat Resistance: Continuous use temperature up to 220°C, with short-term exposure tolerance up to 370°C (700°F). The thread shows minimal thermal shrinkage – approximately 1% at 250°C – maintaining dimensional stability in high-temperature environments. Decomposition begins above 370°C, with carbonization starting around 400°C.
Excellent Electrical Insulation: Meta-aramid thread provides outstanding dielectric strength. The material achieves H-grade insulation rating and is widely used in motor slot insulation, transformer insulation, and cable wrapping tape.
- Chemical & Corrosion Resistance: The chemical structure of aramid 1313 is highly stable, resisting corrosion from most high-concentration inorganic acids, alkalis, hydrolysis, and steam corrosion.

Applications of Meta Aramid Thread



1313 Meta Aramid thread is the preferred choice for safety-critical sewing applications where heat and flame protection are paramount:
Thermal protective clothing (PPE): The stitching of the insulation lining and waterproof breathable layer of the firefighter’s firefighting suit.Arc protection clothing, high-temperature resistant workwear for metallurgical, glass, and ceramic factories.
High temperature filtration and industrial dust removal: This is the largest application market for aramid sewing thread. Used for sewing high-temperature flue gas dust removal filter bags for cement plants, steel plants, and coal-fired power plants.
Aerospace and Transportation: Aircraft seat covers, train car interiors, racing suits, etc
