Meta aramid spun yarn
Meta-aramid fibers are renowned for their combination of heat resistance and strength. They do not ignite, melt, or drip, making them ideal for fireproof apparel. Compared to commodity fibers, meta-aramid fibers offer better long-term retention of mechanical properties at elevated temperatures. Additionally, they have a relatively soft hand, are easily dyeable, and process similarly to commodity fibers, resulting in a wide range of converted products.
Meta aramid is aromatic polyamide. The “Meta” linkage position of the aromatic groups differs from that of Para-Aramids. The chemical bonds are zig-zag in configuration, resulting in a lower tensile and modulus fiber compared to para aramid.
Meta aramid is flexible and higher in elongation however, making it an ideal textile yarn for fabrics.

Features & Benefits
- outstanding heat resistance. Resistant to melting even after many hours of exposure to heat. 75% of original strength is retained after exposure to dry-heat of 200°C for 1000 hours. 60% of original strength is retained after exposure to wet-heat at 120°C for 1000 hours.
- Flame resistance The Limiting Oxygen Index (LOI) of Meta-aramid fibre is over 28%. It is a flame retardant fibre that will not burn, melt or drip. Above 370°C our meta-aramid fibre will start to carbonise and decompose.
- Heat insulating properties Meta-aramid fiber has excellent heat insulating properties. These and its high dielectric strength enable Class-H (up to 180°C) insulating paper to be manufactured from it, giving wide application in the production of transformers, dynamos, motors and other forms of high temperature and high voltage electric equipment.
- Chemical Resistance, resistant to most inorganic acid and alkalis.
- Good textile properties . Meta-aramid fibre’s low stiffness and high elongation give excellent textile-like properties and characteristics, allowing processing on all types of conventional textile equipment. The staple version can be processed into yarns – or blended with other fibres – for the manufacture of knitted and woven fabrics as well as non-woven fabrics. Filament yarn can be converted into knitted and woven fabrics.
- Radiation resistance Meta-aramid fibre shows good resistance to α,β and ultraviolet radiation. For example, when the fibre is exposed at 1000Mrad of β radiation accumulation, it shows no loss of strength.
Application
- Flame retardant and protective workwear
- Heat insulation，thermal insulation
