What are the characteristics of aramid cloth

1. Good mechanical properties Meta-aramid fiber is a kind of flexible polymer, its breaking strength is higher than that of ordinary polyester, cotton, nylon, etc., it has a large elongation, soft hand feeling, good spinnability, and can be produced into different deniers and lengths The staple fibers and filaments are woven into fabrics and non-woven fabrics with different yarn counts in general textile machinery, and after finishing, they can meet the requirements of protective clothing in different fields.

2. Excellent flame retardancy 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 fiber are determined by its own chemical structure, so it is a permanent flame retardant fiber that will not reduce or lose its flame retardant properties due to use time and washing times. Newstar® meta-aramid has good thermal stability, can be used continuously at 205°C, and can still maintain high strength at high temperatures above 205°C. Newstar® meta-aramid fiber has a high decomposition temperature, and it will not melt or drip under high temperature conditions, and it will start to char when the temperature is higher than 370°C.

3. Stable chemical properties Meta-aramid 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 fiber has excellent radiation resistance. For example, under long-term irradiation of 1.2×10-2 w/in2 ultraviolet rays and 1.72×108rads gamma rays, its intensity remains unchanged.

5. Durability Meta-aramid has excellent friction resistance and chemical resistance. After 100 times of washing, the tear strength of the fabric processed with Newstar® meta-aramid can still reach more than 85% of the original strength.
