Aramid Flame Retardant Fabric

Nowadays, the work environment of front-line workers in many companies is rather harsh and the occupational hazards they face are various. Among them, fire accidents caused by electric shock are one of the major hazards faced by workers. The most direct way to avoid the hazard of fire is to wear protective clothing with flame retardant effect. When encountering the hazard of flame, the clothing will produce shielding effect such as heat insulation, reflection, absorption, carbonization, etc., thereby protecting the worker from open flame or heat source. hurt.

       At present, more high-end flame retardant work clothes are made of aramid flame-retardant fabrics. Here we come to understand the characteristics and advantages of aramid flame-retardant fabrics.aramid fabric.jpg


Aramid flame-retardant fabric is called "polyphthaloyl diamine" and English is Aramid fiber. It is a new high-tech synthetic fiber. The fabric has super high strength, high modulus and high temperature resistance, acid and alkali resistance, light weight and other excellent properties; its strength is 5 to 6 times the steel wire, modulus is 2 to 3 times of steel wire or glass fiber, toughness is steel wire 2 times, and the weight is only about 1/5 of the steel wire; at a high temperature of 560 degrees, it does not decompose and melt; it has good insulation and anti-aging properties. Therefore, many people think that the discovery of aramid fiber is a very important historical process in the fire-retardant material industry.

       Aramid fabric characteristics

1. Good mechanical properties

       Aramid fiber is a kind of flexible polymer with higher breaking strength than ordinary polyester, cotton, nylon, etc. It has high elongation, soft hand feeling, and good spinnability. It can produce short fibers and filaments with different denier and length. General textile machinery made of different yarns woven into fabrics, non-woven fabrics, after finishing, to meet the requirements of different areas of protective clothing.

2. Excellent flame retardant and heat resistance

       The flame-retardant properties of aramid are determined by its own chemical structure, and therefore it is a permanent flame-retardant fiber. It will not reduce or lose its flame retardant performance due to the use time and the number of washings; the limiting oxygen index of meta-aramid (LOI ) is greater than 28, so it will not continue to burn when it leaves the flame, and meta-aramid has good thermal stability, no melting and dripping will occur under high temperature conditions, the fabric can still maintain when the temperature is higher than 205°C High strength, and carbonization begins when the temperature is greater than 370°C. The para-aramid's temperature resistance is higher than that of the meta-aramid, and it will not decompose and melt even at a high temperature of 560°C.

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's radiation resistance is excellent. For example, under long-term irradiation of 1.2 x 10-2 w/in2 ultraviolet rays and 1.72 x 108 rads of gamma rays, their intensities remain unchanged.

5. Durability

       Aramid excellent friction and chemical resistance. After 100 times of aramid fiber, the tear strength of the fabric can still reach more than 85% of the original strength. The most significant feature of para-aramid is high strength and high modulus, its strength is greater than 25 g/d, which is 5 to 6 times that of high-quality steel, 3 times that of glass fiber, and 2 times that of high-strength nylon industrial yarn; 2 to 3 times that of high-quality steel or glass fiber and 10 times that of high-strength nylon industrial wire.

      The 180gsm aramid flame-retardant fabric recommended for you this time is the raw material flame-retardant fabric produced by Xinxiang Weis Textiles&Garments Co.Ltd in accordance with international standards. The fabric has permanent flame-retardant properties and anti-static properties. Good air permeability and moisture permeability as well as comfortable and soft touch make the fabric extremely suitable for making protective clothing suitable for working environment such as high temperature and fire hazards. Non-toxic and odorless when burning, environmental protection and safety of aramid flame-retardant fabrics are the best choice for workers in the power industry, petrochemicals, mining and machinery manufacturing industries.
