1, good mechanical characteristics of the arylon is a flexible polymer, the breaking strength is higher than ordinary polyester, cotton, nylon, etc., elongation is large, soft feel, spinnability is good, can be produced into different sizes, lengths of staple fiber and filament, in the general textile machinery made of different yarn woven fabric, non-woven fabric, after finishing, to meet the requirements of different fields of protective clothing.

2, excellent flame retardant, heat resistance of the aramid ji oxygen limit index (LOI) is greater than 28, so when it leaves the flame will not continue to burn. The flame retardant properties of meta-arylon are determined by its own chemical structure, so it is a permanent flame retardant fiber, which will not reduce or lose flame retardant properties due to use time and washing times. Meta-aramid has good thermal stability, can be used continuously under the condition of 205 ° C, and can still maintain a high temperature of more than 205 ° C. Meta-aramid has a high subjie temperature, and it will not melt and melt drop under high temperature conditions, and it will start carbonizing when the temperature is greater than 370℃. 3, stable chemical properties of the aramid has excellent resistance to most chemical substances, can withstand most high concentrations of inorganic acids, good alkali resistance at room temperature. 4, radiation resistance meta-aramid radiation resistance is very excellent. For example, under the long-term irradiation of 1.2×10-2 w/in2 ultraviolet rays and 1.72×108rads of gamma rays, its intensity remains unchanged. 5, durability aramid excellent friction resistance and chemical resistance, after 100 times of washing, the fabric processed with aramid can still tear more than 85% of the original qiangli.
