What is acrylic fiber

What fiber does acrylic belong to? Acrylic yarn is the trade name of polyacrylonitrile fiber in China, and it is called "Aolun" and "Cashmere" abroad. It usually refers to the synthetic fiber made by wet spinning or dry spinning with more than 85% acrylonitrile and the copolymer of the second and third monomers.

Acrylic fiber is called artificial wool. It has the advantages of softness, bulkiness, easy dyeing, bright color, light resistance, anti-bacterial, and worm resistance. It can be pure spun or blended with natural fibers according to the requirements of different uses. Its textiles are widely used in clothing, decoration, industry and other fields

The role of polyacrylonitrile fiber As the secondary reinforcement material of concrete, polyacrylonitrile fiber can significantly improve the toughness and impact resistance of concrete, effectively prevent the generation and development of cracks, and improve the impermeability, frost resistance and other durability of concrete. In addition, as an industrial fiber product for strengthening asphalt concrete, it can not only greatly improve the cohesiveness, high temperature stability and fatigue durability of asphalt pavement, but also has the performance of low temperature crack prevention and reflective crack prevention. Effectively improve tensile, shear, compressive and impact strength. Its great role and application prospects in concrete have been recognized and accepted by the engineering community.
