Aramid fiber is a new type of high-tech synthetic fiber with excellent properties such as soft texture, low density, high strength, high modulus, acid and alkali resistance, light weight, and high temperature resistance. Aramid fiber can be used at 220 degrees Celsius for more than 10 years, and does not decompose or melt at 560 degrees Celsius. Its strength is 5-6 times that of steel wire, its modulus is 2-3 times that of steel wire or glass fiber, its toughness is twice that of steel wire, and its weight is only about 1/5 of that of steel wire. At a temperature of 560 degrees, it does not decompose or melt. Aramid fiber has good insulation and anti-aging properties, and has a long life cycle.
Aramid fiber has a strength of 5-6 times that of steel wire, a modulus of 2-3 times that of steel wire or glass fiber, a toughness of 2 times that of steel wire, and a weight of only about one-fifth that of steel wire. It is an important basic material in high-tech fields such as aerospace, aviation, national defense, electronics, and chemical development.
The characteristics of aramid fibers:
1.With good performance
Aramid fiber is a flexible polymer with a higher breaking strength than ordinary polyester, cotton, nylon, etc. It has a higher elongation, a soft feel, and good spinnability. It can be produced into short fibers and long filaments of different sizes and lengths, and woven into fabrics or non-woven fabrics with different yarn counts on general textile machinery. After finishing, it meets the requirements of protective clothing in different fields.
2. Excellent flame retardancy and heat resistance
The ultimate oxygen index of aramid is greater than 28, so it will not continue to burn when it leaves the flame. The flame retardant properties of aramid are determined by its own chemical structure, and therefore it is a permanent flame retardant fiber that will not decrease or lose flame retardant performance due to use time and washing times. aramid has good thermal stability and can be used continuously at 205 ℃, maintaining high strength even at high temperatures above 205 ℃, Aramid fibers have a high decomposition temperature and do not melt or drip under high temperature conditions. Carbonization only begins when the temperature exceeds 370 ℃
3. Stable chemical properties
Meta aramid has excellent resistance to most chemical substances, can withstand most high concentrations of inorganic acids, and has good alkali resistance at room temperature.
4. Radiation resistance
The radiation resistance of meta aramid fibers is very excellent.
The excellent friction and chemical resistance of meta aramid fibers can still achieve a tearing strength of over 85% of the original strength after 100 washes
Aramid fibers have good thermal stability. At high temperatures, it does not deform until it decomposes. It can be used for a long time at 180 ℃, and the strength and modulus do not decrease after one week at 150 ℃.
