Nowadays, the front-line workers of many enterprises are in a harsh working environment, and there are many occupational hazards. Among them, fire accidents caused by electric shock are one of the main hazards faced by the staff. The most direct way to avoid the flame hazard is to wear protective clothing with flame retardant effect. When encountering the danger of flame, the clothing will have shielding effect such as heat insulation, reflection, absorption, carbonization and isolation, thus protecting workers from open flames or heat sources hurt.
1. Good mechanical properties
Aramid is a flexible polymer with higher breaking strength than ordinary polyester, cotton, nylon, etc. It has large elongation, soft handfeel and good spinnability. It can produce short fibers and filaments of different denier and length. Generally, textile machinery is made into different fabrics and woven into fabrics and non-woven fabrics. After finishing, it meets the requirements of protective garments in different fields.
2. Excellent flame retardant and heat resistance
The flame retardant properties of aramid fiber are determined by its own chemical structure, so it is a permanent flame retardant fiber, which will not reduce or lose flame retardant performance due to the time of use and washing; the limiting oxygen index (LOI) of meta-aramid is greater than 28, so it does not continue to burn when it leaves the flame, and the meta-aramid has good thermal stability, does not produce melting and melting at high temperatures, and the fabric remains at temperatures above 205℃. Higher strength, and carbonization begins when the temperature is greater than 370℃. The temperature resistance of the para-aramid is higher than that of the meta-aramid, and it does not decompose and melt even at a high temperature of 560℃.
3. Stable chemical properties
Aramid has excellent chemical resistance, is resistant to most high concentrations of inorganic acids, and has good alkali resistance at room temperature.
4. Radiation resistance
Aramid has excellent radiation resistance. For example, under the long-term irradiation of 1.2×10-2w/in2 ultraviolet rays and 1.72×108 rads of γ-rays, the strength remains unchanged.
Aramid has excellent resistance to friction and chemicals. After 100 times of washing the meta-aramid, the tear strength of the fabric can still reach more than 85% of the original strength. The most remarkable characteristic of para-aramid is high strength and high modulus. Its strength is more than 25 g/denier, which is 5-6 times of high-quality steel, 3 times of glass fiber and 2 times of high-strength nylon industrial yarn; modulus is 2 to 3 times higher quality steel or fiberglass, 10 times higher than high strength nylon industrial yarn.
Raw material flame retardant fabrics produced in accordance with international standards. The fabric has permanent flame retardant and anti-static properties, good breathability and moisture permeability, and a comfortable soft touch makes the fabric ideal for protective clothing suitable for high temperature and fire hazards. It is non-toxic and tasteless when burned. The environmentally safe and aramid flame retardant fabric is the best choice for workers in the power industry, petrochemical, mining and machinery manufacturing industries.
