Acrylic yarn can be divided into many kinds due to different production methods. First of all, let's understand the production mode of acrylic yarn. The raw material of acrylic fiber is cheap propylene, which is a by-product of petroleum cracking. When the polyacrylonitrile copolymer is heated to more than 230C, it only decomposes and does not melt. Therefore, acrylic yarn cannot be melt spun like polyester and nylon fibers. Therefore, acrylic yarn manufacturers adopt the method of solution spinning. Spinning can be done by dry method or wet method. The dry spinning speed is high, which is suitable for spinning silk like fabrics. Very suitable for spinning short fibers, fluffy and soft, suitable for making wool like fabrics.
