Dust collector bags are a well-structured, high-performance filtering material. These bags not only feature the advantages of dimension stability, low elongation and shrinkage, and high strength of glass fiber fabrics, but also have the characteristic of single-fiber felt layers and a three-dimensional microporous structure with a high porosity rate. Compared to other fiber felt filter bags primarily based on actual reports, they offer reasonable pricing and higher temperature resistance, but their operating resistance is higher than that of general high-temperature fiber filter materials.
