Characteristics of Aramid

Characteristics of Aramid

1. Good mechanical properties. Meta-aramid is a flexible polymer with higher breaking strength than ordinary polyester, cotton, nylon, etc. with higher elongation, soft hand feeling, good spinnability, and can be produced into different deniers and lengths. The short fibers and filaments are made into fabrics and non-woven fabrics with different yarn counts in general textile machinery. After finishing, they can meet the requirements of protective clothing in different fields.
2. Excellent flame retardant and heat resistance The limiting oxygen index (LOI) of meta-aramid is greater than 28, so it will not continue to burn when it leaves the flame. The flame-retardant properties of Newstar®meta-aramid is determined by its own chemical structure, so it is a permanent flame-retardant fiber that will not decrease or lose flame-retardant properties due to use time and washing times. Newstar®meta-aramid has good thermal stability, can be used continuously at 205℃, and can still maintain high strength under high temperature conditions greater than 205℃.Newstar® meta-aramid has a high decomposition temperature, and will not melt or melt under high temperature conditions. Carbonization begins when the temperature is greater than 370°C.
3. Stable chemical properties meta-aramid fiber has excellent resistance to most chemical substances, can withstand most high-concentration inorganic acids, and has good alkali resistance at room temperature.
4. Radiation resistance meta-aramid has excellent radiation resistance.
5. Durable meta-aramid has excellent friction and chemical resistance. After 100 washing, the tearing strength of fabrics processed with Newstar®meta-aramid can still reach more than 85% of the original strength.
