What is Aramid Fiber?

The full name of aramid is aromatic polyamide fiber, which is an organic synthetic material with high strength, high modulus, low density and high wear resistance, and has stable chemical properties

Aramid has excellent properties such as high modulus, high breaking strength, low thermal shrinkage and low breaking elongation, and is an ideal reinforcing fiber material.

Since single aramid fiber has defects when used, and its strength decreases after contact with water, aramid is usually made into composite materials and used as reinforcing fiber in materials to adapt to different use environments and improve the performance of the material.

Application of 3,4'-ODA (CAS No.: 2657-87-6) in Aramid Fiber

3,4'-Diaminodiphenyl ether is an important chemical raw material. It can be used as a modified monomer in the preparation of heterocyclic aromatic polyamide fibers. By introducing 3,4'-diaminodiphenyl ether into the molecular structure of heterocyclic aramid, the high tensile strength at break of heterocyclic aramid can be maintained while the elongation can be greatly improved and the composite performance can be better. This process is achieved by degassing, filtering, plastic stretching, washing, drying, oiling, heat treating the spinning solution obtained by polymerization, and finally winding to obtain the finished fiber. The tensile strength at break of the prepared high-strength and high-elongation heterocyclic aromatic polyamide fiber can reach 28.0-35.0 cN/dtex, and the elongation is 4.5-10.0%. It has broad application prospects in the field of national defense and military industry, especially in the field of bulletproof and special rubber reinforcement.
