Nomex fabrics for flame resistant conveyor belts

Nomex fabric is a special material made of aramid fibers, which are a kind of synthetic polymer that DuPont created in the 1960s. Nomex fabric has the outstanding feature of being able to resist high temperatures and flames, without melting, dripping or igniting in the air. This makes Nomex fabric appropriate for making protective clothing for various sectors that face thermal hazards, such as firefighters, industrial workers, military aviators, motosport pilots, hospital gowns, and others. Nomex fabric also contributes to reducing environmental pollution, as it can filter out harmful exhaust gases in different industrial plants that deal with hot processes, such as asphalt, cement, steel smelting, and nonferrous metal production. Nomex fabric has a flexible and elastic structure, which gives it a similar feel to natural fabrics. Nomex fabric comes in different forms, such as paper, felt, woven, and fiber.

The industrial processing of Nomex fabric requires several steps, depending on the form and the end use of the product. For instance, to produce Nomex paper, the fibers are first dissolved in a solvent and then extruded into a thin film. The film is then dried and calendered to achieve the desired thickness and smoothness. The paper can then be cut into sheets or rolls for further applications. To produce Nomex felt, the fibers are first carded and cross-lapped to form a web. The web is then needled to interlock the fibers and increase the density. The felt can then be treated with various finishes to enhance its properties. To produce Nomex woven fabric, the fibers are first spun into yarns and then woven into different patterns and textures. The woven fabric can then be dyed, printed or embroidered with logos and symbols. To produce Nomex fiber, the fibers are first cut into short lengths and then crimped to increase their bulkiness. The fiber can then be used for filling or blending with other fibers.
