3K colourful Kevlar weave composite fabric
Kevlar, formerly known as KEVLAR, is also translated as Kevlar or Kevlar. It is a brand name of an aramid fiber material product developed by DuPont of the United States. The original name of the material is "poly-terephthaloyl-p-phenylenediamine". The repeating unit of the chemical formula is-[-CO-C6H4-CONH- C6H4-NH-]-The amide group attached to the benzene ring is a para structure (the meta structure is another product named Nomex, commonly known as fire-resistant fiber).
Kevlar fiber characteristics
1. Permanent heat resistance and flame retardancy, the limit oxygen index Loi is greater than 28.
2. Permanent antistatic.
3. Permanent resistance to acid and alkali and organic solvents.
4, high strength, high wear resistance, high tear resistance.
5. In case of fire, no molten droplets are generated and no toxic gas is generated.
6. When the cloth is burned, the cloth becomes thicker, which enhances the sealing performance and does not crack.
