Flame retardant fabrics are divided into two processes: fiber flame retardant and finishing flame retardant. Fiber flame retardant fabrics, such as aramid, acrylic cotton, DuPont Kevlar, Nomex, etc. Fiber flame retardant fabrics have permanent flame retardancy and good thermal stability.

The principle of flame-retardant fiber is to reduce the generation of flammable gases during thermal decomposition and to hinder the basic reactions in the gas phase combustion process. It then absorbs the heat in the combustion zone, diluting and isolating the air to prevent combustion.

Flame retardant fabric

For example, Cloth woven with aramid flame-retardant fiber has good dimensional stability and can be used for a long time at a temperature of 250 degrees Celsius, with a thermal shrinkage rate of only 1%. The softening temperature of the fiber is 373 degrees Celsius, and it does not start to decompose until it exceeds 400 degrees Celsius. During decomposition, the cloth surface thickens and the fibers expand. The outside of the cloth surface is 900-1300 degrees Celsius to isolate heat transfer without cracking.

Flame-retardant Oxford cloth is a common flame-retardant fabric. When people design flame-retardant Oxford cloth, in addition to the flame-retardant function, they also add corrosion resistance, high temperature resistance, and anti-static materials, making Oxford cloth It is no longer just a fireproof function, but also multi-functional.

Flame retardant fiber

Oxford cloth Specifications: 1680D, 1200D, 900D, 600D, 420D, 300D, 210D, 150D, etc.

Oxford cloth functional classification: flame retardant Oxford cloth, waterproof Oxford cloth, PVC Oxford cloth, pu Oxford cloth, camouflage Oxford cloth cloth, fluorescent oxford cloth, printed oxford cloth, composite oxford cloth, etc.
