There are mainly two types of modified polyacrylonitrile fibers produced in the recent industrial production: fibers made of copolymer of acrylonitrile and vinyl chloride; The fiber is made of the copolymer of acrylonitrile and vinylidene chloride, namely vinylidene chloride polyacrylonitrile fiber. These two types of modified polyacrylonitrile fibers are sometimes collectively referred to as nitrile chloride fibers, which have good flame retardancy.

Project description: Modacrylic/cotton blended yarn Specification: 32S Carding technology: combed cotton Color: dyeable yarn Form: cone spinning technology: vortex spinning Composition and content: 60% Modacryc, 40% cotton.

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.
