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