Acrylic is the brand name of acrylic fiber in China. Acrylic has excellent performance, by its very nature close to wool, so it is "synthetic wool" said. Industrial production since 1950, has been greatly developed. The 1996 world total of 2.52 million tons of acrylic fiber, production of 297,000 tons in China, China will vigorously develop the acrylic fiber production.
Acrylic is usually known as the polyacrylonitrile fiber and acrylonitrile (known firstmonomer) accounted for only 90%~94%, 5%~8% monomer II, third monomer for0.3%~2.0%. This is due to the lack of acrylonitrile polymer single fibers for flexible,brittle, dye is very difficult. In order to overcome these shortcomings of the Pan, using the method of adding a second monomer, the fiber soft; add third monomer, improving the dyeing ability.
