The Polyester needle felt nonwoven filter fabric has strong tensile strength, excellent resistance to abrasion and acid, and is safe for use with food. It is a cost-effective filter material that is widely used in various industries for collecting dust (such as in the production of dust filter bags).
Hongyuan Envirotech has a highly experienced and skilled team, as well as modern needle punching lines and top-quality raw materials. This ensures that the polyester needle felt filter fabric from Hongyuan has consistent air permeability and thickness, as well as high tensile strength. The fabric has a smooth surface that allows for easy release of dust, making it durable.
Depending on the specific working conditions and emission requirements, the polyester filter fabric can be treated with various finishes. These include water and oil repellent treatments, PTFE suspension bath, and PTFE membrane lamination. These treatments enhance the filtration performance of the filter fabric, making it perfect for collecting dust.
