Product Description

What is aramid fabric kevlar yarn?
Aramid Fabirc yarn is a new type of high-tech synthetic fiber with super high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight and other excellent properties. Its strength is 2 to 3 times that of steel wire or glass fiber, and its toughness is steel wire. The weight is only about 1/5 of the steel wire, and it does not decompose or melt at a temperature of 560 degrees. It has good insulation and anti-aging properties, and has a long life cycle.
Kevlar fiber is a high strength organic synthesis fiber material. It has the character of high hardness, high toughness, lightweight and high resistance to abrasion
Kevlar yarn use 100% Kevlar fiber and multi-strands weaving process. This process will improve our lines abrasion resistance ability and it will not easy to be cut.
Whether you are a fishing lover or a stunt kites player, or for outdoor activities and extreme sports, the Kevlar line is always a wonderful choice.

Brief introduction:
What is kevlar twisted yarn?
Kevlar twisted yarn has extremely high tensile strength, exceeding 28 grams per denier, which is 5-6 times that of high-quality steel, with a modulus 2-3 times that of steel or fiberglass, toughness twice that of steel, and weight only 1/5 of steel. The strength and toughness of aramid 1414 also make it extremely difficult to cut and process, requiring expensive specialized tools.
Aramid 1414 has a wide range of continuous use temperatures, allowing for long-term normal operation within the range of -196 ºC to 330 ºC. The shrinkage rate at 150 ºC is 0, and it does not decompose or melt at high temperatures of 560 ºC. Its heat resistance is superior to that of aramid 1313, and it has good insulation and corrosion resistance, with a long life cycle, earning it the reputation of "synthetic steel wire".
Mechanical properties of Kevlar twisted yarn
The strength is 3.6Gpa, the elongation modulus is 131Gpa, and the elongation at break is 2.8% -3.5%. It has extremely high strength, with a weight to weight ratio of 5-6 times that of steel wire, a modulus of 2-3 times that of steel wire or fiberglass, and 7 times that of high-strength nylon. It is recognized as one of the world's sewing threads.
Thermal properties of Kevlar twisted yarn
Long term use temperature: 380 ºC
Axial thermal expansion coefficient: -2 × 10 ^ (-6)/K
Thermal conductivity: 0.048 W (m · K)
It has high stability in temperature performance, not only able to be used for a long time in the temperature range of -196 ºC to 380 ºC without significant changes or losses, but also has non solubility, non combustion (fire resistance), and will only start carbonization at 427 ºC. Even at a low temperature of -196 ºC, it will not become brittle or suffer performance losses. It can also withstand temperature resistance up to 585 ºC for short periods of contact.
