Meta-aramid fabrics have excellent high temperature resistance, good dimensional stability ,excellent spinnability, fire resistance and corrosion resistance. It can be widely used in steel, cement, power plants, chemicals, asphalt and other industries.
The meta-aramid with good mechanical properties is a flexible polymer with higher breaking strength than ordinary polyester, cotton and nylon. It has a large elongation, soft handfeel and good spinnability. It can produce short fibers and filaments of different denier and length. It is woven into fabrics and non-woven fabrics in different textile machinery. To meet the requirements of protective clothing in different fields.
It has excellent flame retardant and heat resistance. The meta-aramid has a limiting oxygen index (LOI) of more than 28, so it does not continue to burn when it leaves the flame. The flame retardant properties of meta-aramid are determined by its own chemical structure and are therefore a permanent flame retardant fiber that does not reduce or lose flame retardancy due to time of use and washing. The meta-aramid has good thermal stability and can be used continuously at 205 ° C. It can maintain high strength even at temperatures above 205 ° C. The meta-aramid has a high decomposition temperature and does not melt or melt under high temperature conditions, and carbonization starts when the temperature is higher than 370 °C. It has stable chemical properties.
It has excellent resistance to most chemicals, and is resistant to most high-concentration inorganic acids, and has good alkali resistance at room temperature. The meta-aramid has excellent radiation resistance. For example, under the long-term illumination of ultraviolet rays and gamma rays, the intensity remains unchanged. The interfacial aramid has excellent anti-friction and chemical resistance. After 100 times of washing, the torn strength of the fabric treated with meta-aramid can still reach more than 85% of the original strength.
