Acrylic fiber which is a name of artificial wool and has low price, so the acrylic fiber becomes the best substitute of wool and cotton. In the chemical fiber industry of China, polyester fibers are mainly used for cotton-like or silk-like fabrics, and wool-like fabrics take acrylic fibers as a main raw material. The acrylic fiber has fluffy appearance, soft hand feeling, good light resistance and weather resistance, and elasticity and heat retention comparable to those of wool, and is popular with consumers. The acrylic fiber is the most dominant raw material in wool spinning and artificial fur in China. The excellent performance of the acrylic fiber enables the acrylic fiber to be widely applied to three fields of clothes, clothes and industry.

The main production process mode of the prior acrylic fiber is a wet spinning method: raw materials such as acrylonitrile, polymerization monomers and the like are subjected to polymerization reaction to generate a stock solution; filtering, defoaming and adjusting the temperature of the stock solution, and spraying the stock solution into a coagulating bath through a spray head to be coagulated into filaments; forming the strand silk after steam drafting, washing, drying and heat setting; and curling, cutting and packaging the formed acrylic fibers.

In the process of coagulating the stock solution into filaments in a coagulating bath, the filaments are often intertwined and knotted in a staggered manner to form lumps, which affects the normal operation of the subsequent process and leads to low quality of the produced acrylic fibers. Meanwhile, the existing acrylic fibers have the defects of poor fireproof performance and low safety.
