Special industrial fabric is a type of textile with special properties and functions, which is made from special fibers or composite materials processed through special processes. The performance of special industrial fabrics mainly depends on their raw materials and processing technology, which determine their structure, composition, morphology, and surface characteristics.

Raw materials are the foundation of special industrial fabrics, which determine their inherent properties and potential functions. The raw materials for special industrial fabrics can be divided into natural fibers, artificial fibers, and inorganic fibers. Natural fibers such as cotton, linen, silk, etc. have good hydrophilicity, breathability, and biocompatibility; Artificial fibers such as polyester, nylon, spandex, etc. have high strength, high modulus, wear resistance, and chemical resistance; Inorganic fibers such as glass fibers, carbon fibers, ceramic fibers, etc., have high temperature resistance, corrosion resistance, flame resistance, and conductivity.

The processing technology is the key to special industrial fabric, which determines its external form and actual function. The processing technology of special industrial fabrics can be divided into textile technology, coating or composite technology, and post finishing technology. Textile technology refers to the process of spinning, weaving, or needling fibers of different types and specifications into substrates of different structures and shapes; Coating or composite process refers to the application or bonding of one or more layers of materials with special functions, such as rubber, plastic, metal, or other fibers, onto the substrate; Post finishing process refers to a series of physical or chemical treatments performed on the substrate, coating, or composite fabric, such as dyeing, printing, waterproofing, anti fouling, and anti-static.

Different combinations of raw materials and processing techniques produce different special industrial fabrics, which have different properties and functions, such as high temperature resistance, corrosion resistance, flame resistance, high strength, high modulus, high elasticity, reverse osmosis, efficient filtration, adsorption, ion exchange, light conduction, conductivity, etc. These properties and functions enable special industrial fabrics to meet various complex and demanding usage conditions and requirements, providing new solutions and development opportunities for various industries.
