Polyacrylonitrile modified fiber is also called modified polyacrylonitrile fiber. Synthetic fiber made of linear polymer copolymer containing 35%~85% acrylonitrile monomer. The United Carbide Company of the United States began its industrial production in 1948, with the trade name Dynel.

Synthetic fiber made of polyacrylonitrile or acrylonitrile copolymer containing more than 85% (mass percentage) of acrylonitrile. The common second monomer is non-ionic monomer, such as methyl acrylate and methyl methacrylate, and the third monomer is ionic monomer, such as sodium allylsulfonate.

The performance of polyacrylonitrile fiber is very similar to wool, with good elasticity. When it is stretched by 20%, the resilience can still be kept at 65%. It is fluffy, curly and soft, and its warmth retention is 15% higher than that of wool. It is called synthetic wool. The strength is 22.1~48.5 cN/tex, which is 1~2.5 times higher than wool. It has excellent light resistance. It can be used as curtain, curtain, tarpaulin, and cannon coat after being exposed to the sun for one year. It can resist acid, oxidant and general organic solvent, but has poor alkali resistance.
