When the level of industrial dust reaches the point where it could explode, it becomes highly prone to causing explosions and fires if it comes into contact with things like sparks from static electricity. This is particularly true for dusts like flour, chemicals, and coal. To gather up these dusts using cloth bags, it is essential to use filter bags that have anti-static properties. Making anti-static filter material involves adding conductive fibers to the warp yarn of the base fabric or blending them with chemical fibers while making needle felt. There are different types of anti-static needle felts available, like combinations of polyester and aramid in various arrangements. These felts have excellent resistance to wear and have a surface resistance that ranges from 103 to 108(Ω.cm). There are also options for customization to meet specific needs. Our dedication to quality is evident in our thorough testing process, where each material undergoes extensive experimentation to ensure its stability and prolong its lifespan.
