Polyacrylonitrile fibers are weather-resistant and have excellent toughness. They are industrial-specific synthetic fibers.

Polyacrylonitrile fibers also known as acrylic fibers, are made from the polymer of polyacrylonitrile through multiple processes such as dissolution spinning, solidification forming, stretching and shaping, and post-treatment modification. The product has balanced comprehensive performance, closely resembling the texture of natural fibers, while possessing the stability and durability specific to synthetic fibers. They are widely used in various civil and industrial fields such as geotechnical engineering, concrete reinforcement, outdoor textiles, thermal insulation fabrics, and filtration materials. They are highly versatile functional fibers.

The fiber filament of this product is uniform and regular, with moderate fiber curling degree, good adhesion performance, and excellent overall loft. The fiber structure is stable, with balanced mechanical performance, and has good tensile and bending resistance. It is not prone to breaking, shedding, or deformation during daily use. It is highly compatible during textile processing, enabling smooth completion of spinning, weaving, needling, blending, and other processes. It runs stably on the machine without problems such as broken fibers or loose threads. It is suitable for large-scale continuous production.

Polyacrylonitrile fibers have excellent weather resistance and anti-aging properties. They are highly adaptable to light and climate changes, and are not prone to yellowing, brittleness, or performance degradation when exposed to the outdoors for a long time. The material has stable chemical properties and good resistance to acids, alkalis, and chemical corrosion, and is not easily eroded or damaged by conventional media. It can adapt to complex working conditions such as outdoor, geotechnical engineering, and humid environments, maintaining stable physical structure and performance over the long term.

As an reinforcing fiber material, this product is often used in building material systems such as concrete and mortar, effectively improving the brittleness of the base material, inhibiting the generation and extension of micro-cracks, enhancing the anti-cracking, anti-erosion, and anti-freezing performance of building materials, and optimizing the stability of the engineering structure. At the same time, the fiber has good thermal insulation and breathability, and the coloring effect is uniform, with stable color fastness. It can be used in the production of various thermal insulation fabrics and decorative fabrics, and the finished product has uniform appearance and good user experience.

The enterprise strictly follows industry production standards, conducting meticulous control throughout the process from raw material ratio, spinning formation, process modification to product inspection to ensure uniform fiber batch quality and stable performance. With excellent structural toughness, outstanding weather resistance and anti-aging ability, and wide adaptability to various scenarios, polyacrylonitrile fibers can provide stable and reliable raw material support for the construction engineering and textile manufacturing industries, helping to upgrade the quality of terminal products.
