What is the flame retardant properties of aramid?

The main raw material of aramid cloth is aramid sewing thread, aramid fiber bit and aramid fiber between aramid fiber points, mainly density and thickness, velvety hair, rich hairiness, high strength and dimensional stability Good properties, no brittleness and high temperature resistance, corrosion resistance, good toughness and shrinkage, good wearability, large surface area, good combination of materials and other materials, is a strong material for filling.

Aramid fabric has good mechanical properties. Aramid fabric is a kind of flexible polymer. Its breaking strength is larger than ordinary polyester and cotton. It can produce different lengths, short fiber lengths and filaments. Textile machinery is woven from different yarns. Fabrics, non-woven fabric finishing, to meet the requirements of protective clothing in different fields. Flame retardancy, heat resistance, aramid fabric oxygen index is greater than 28, so that when it leaves the flame to burn.

The flame retardant properties of aramid are determined by its chemical structure and are a flame retardant fiber that does not use time and wash time to reduce or lose flame retardant properties. Aramid has good thermal stability. The aramid is decomposed at high temperature and does not melt into water droplets under high temperature conditions before it begins to carbonize at temperatures above 370 c. Stable performance, aramid fabric has excellent resistance to most chemicals and high concentration of inorganic acid. Radiation resistance. Radiation resistant aramid fabrics have excellent properties. Durability, after excellent abrasion and chemical resistance of the aramid fabric, after 100 washes, the fabric tear strength of the aramid processing can still reach more than 85% of the original strength.

Aramid cloth is a kind of flexible polymer. Its breaking strength is higher than ordinary polyester, nylon, cotton, etc., its elongation is large, its hand feel is soft, its spinnability is good, and it can produce different denier, length and filament. Short fibers are made into different fabrics and non-woven fabrics in general. After finishing, they can meet the requirements of protective clothing in different fields. The flame retardant properties of this material are determined by its own chemical structure, because it is a kind of flame retardant fiber, which will not be reduced or lose flame retardant performance due to the time of use or the number of washings. It has very good heat. Stability, even in high temperature environments, can be used continuously and still maintain high strength. The solution temperature is high, and melting and melting do not occur under high temperature conditions.

It has good chemical resistance and can withstand most high concentrations of inorganic acids. It has good acid and alkali resistance at room temperature. The radiation resistance is also very good. Under the long-term exposure of ultraviolet light, the strength can still be kept unchanged, and the excellent friction resistance. After 100 times of washing, the tearing strength of the meta-aramid processed fabric can still reach 85% of the original strength. the above.
