Kevlar in China we call it 1414 filament yarn Its scientific name is Aramid filament also called para-aramid.
It's a new kind of composite materials developed in 1965.
The key feature is super high strength and light in weight, under the condition of equal weight, its strength is 5times higher than steel wire, 10times higher than aluminum.
It is one of the most strongest fiber in the world.
2. Kevlar yarn Feature

The polyester Camouflage Fabric is usually made of 100% polyester fibre. Sometimes it's coated with PU or PVC.These are woodland ,jungle,desert,sea and sky patterns. After special treatment, the surface of the camouflage has near infrared retardant(IRR) function. At the same time, it can increase the functions of flame retardant and waterproof. In addition, high breaking and tearing strength and good printing color fastness are the basic requirements.It's worn comfortably.It's widely used for bags,vest,sleeping bags ,tent,rain coat and so on.
It has good wrinkle resistance, low price, high strength, strong corrosion resistance and good light fastness.
