Polyacrylonitrile fiber of Shandong Huimin Taili Chemical Fiber Products Co., LTD. : A synthetic fiber that combines texture and performance!

Polyacrylonitrile fiber is a synthetic fiber made by wet or dry spinning with acrylonitrile as the main raw material (usually accounting for more than 85%) and a small amount of copolymer monomers (such as methyl acrylate, itaconic acid, etc.) added. Due to its appearance and performance being close to wool, it is often called "synthetic wool". It combines the fine texture of natural fibers with the durability of synthetic fibers, and is widely used in the fields of textiles and industrial textiles. It is an important category in the synthetic fiber family that is both practical and comfortable.

From the perspective of production process, the manufacturing of polyacrylonitrile fibers involves three core steps: polymerization, spinning and post-treatment. Firstly, acrylonitrile and copolymer monomers undergo solution polymerization under the action of an initiator to form a polyacrylonitrile spinning stock solution. The stock solution needs to be filtered and degassed to ensure its purity. Subsequently, the spinning process is selected based on product requirements - wet spinning involves squeezing the original liquid through a spinneret into a coagulation bath to solidify the polymer into filaments, which is suitable for the production of conventional fibers. Dry spinning involves squeezing the original solution into a hot air channel. Through the evaporation of the solvent, the filament is formed, which is more suitable for making fine denier or irregular-shaped fibers. After the filaments are formed, they need to go through post-treatment processes such as stretching (to enhance fiber strength), water washing (to remove residual solvents), drying and shaping, and curling (to increase fiber cohesion), and finally are made into polyacrylonitrile fiber products. In production, the precise control of polymerization reaction temperature, spinning speed and solidification conditions directly affects the mechanical properties and appearance texture of fibers.

In terms of core performance, the advantages of polyacrylonitrile fibers lie in the balance between texture and durability. Firstly, its appearance and touch are close to wool, with good fluffiness and elasticity. The fabric made from it is not prone to wrinkling and has a natural luster, providing a relatively high level of comfort when worn or used. Secondly, it has excellent light fastness. It is not prone to fading or aging under long-term exposure to light. Its light fastness is superior to that of most synthetic fibers, making it suitable for outdoor or long-term exposure scenarios. Thirdly, it has strong thermal insulation. The micro-porous structure inside the fibers can store air, forming an insulating layer. Its thermal insulation effect is close to that of wool, and it is lighter in weight. In addition, it also has good chemical resistance, with certain resistance to common acids, alkalis and detergents. At the same time, its moisture absorption is moderate (with a moisture regain rate of about 1.2%-2.0%), avoiding the stuffy feeling of some synthetic fibers.

In terms of application scenarios, Polyacrylonitrile fiberrs cover the demands of multiple fields. In the textile field, it can be used to make knitted sweaters, scarves, blankets and other warm fabrics, enhancing the product experience by taking advantage of its wool-like texture and warmth retention. In the home textile field, it is suitable for curtain, sofa fabric, etc., ensuring long-term usage effect with its lightfastness and wear resistance. In the field of industrial textiles, it can be used as a filter material and tent fabric, and is suitable for outdoor or industrial working conditions by relying on its weather resistance and strength. In special fields, flame-retardant polyacrylonitrile fibers can also be modified to be used in protective equipment such as fire suits and fireproof curtains.

With the upgrading of market demands for material quality and functionality, polyacrylonitrile fibers are also continuously being optimized. By adjusting the proportion of copolymer monomers to improve the dyeability and elasticity of fibers, developing fine and ultra-fine denier varieties to enhance softness, or introducing environmentally friendly production processes to reduce solvent emissions, the synthetic fiber industry can maintain its original advantages while better meeting the demands of high-end textiles, green environmental protection and other niche markets, providing support for the diversified development of the synthetic fiber industry.
