Bulletproof high-tech special fiber, aramid fiber fire

Aramid fiber was born in the late 1960 s, initially as the development of material and important strategic goods and materials and the secret is not, added a lot of mystery. After the end of the cold war, aramid as high technical content of the fiber material used in civilian areas, it gradually shows lushan really amused.

Aramid fiber is the full name of aromatic polyamide fiber (English name Aramidfibers), is a kind of new type of special purpose synthetic materials. Because of fiber polymer long-chain molecules contain amide group, so like nylon, both belong to the class of polyamide fiber. But the difference is that constitute a nylon polymer macromolecule chain is connected amide group in fat, and aromatic polyamide fiber is connected amide group in aromatic ring or the derivatives of aromatic ring, so this kind of fiber are collectively referred to as aromatic polyamide fiber and Xinke aramid fabrics for short.

Due to the aromatic base to replace the fat base, molecular chain rigidity increase with the decrease of the flexible, reflected in the fiber performance, and its heat resistance and initial modulus were significantly increased, so the aromatic polyamide fiber is the main categories of organic high temperature resistant fibers. One of the most practical value of varieties has two, one is the molecular chain arrangement is serrated between aramid fiber and the life of aramid 1313; Molecular chain arrangement is a straight line shaped para aramid fiber, for aramid 1414 of life in our country. Both chemical structure similar, but the performance difference is very big, a variety of applications: aramid 1313 for its excellent high temperature resistant insulation to become high quality functional fiber, aramid 1414 excellent metal features make it occupies the important core status in the high performance fibers.
