Needle Punch Filtration Bag Production
topic
Industrial filtration bag production uses needlepunched fabrics from polyester, polypropylene, Nomex, PPS, and fibreglass fibres at 300 to 600 grams per square metre with surface treatments including membrane lamination, singeing, and calendering to produce high-temperature dust filtration bags for pulse-jet fabric filter systems in cement, power generation, and metals industries requiring continuous service at 130 to 260 degrees Celsius.
Role
Produces the primary industrial dust filtration medium for air pollution control in industrial processes where the depth filtration structure of needlepunched felt provides the dust cake formation surface and cake release capability required for pulse-jet cleaning cycles that regenerate filter bags in-service, with fibre type selection governing the maximum service temperature and chemical resistance matching each industrial process exhaust stream chemistry.
