What is a PP filter bag?
The filter bag is made from PP needle punched felt produced by needle punching method. PP fibers are produced using different production equipment and manufacturing procedures based on the characteristics of working conditions and usage requirements. After a special hydrophobic treatment, PP needle felt with high filtration performance and efficiency is obtained through singeing, heat setting, and rolling. Afterwards, it is sewed with PP needle felt to form a traditional PP filter bag.
What are the special production processes for PP filter bags?
The PP filter bag is made from PP needle felt. The most traditional PP needle felt on the market only requires acupuncture, singeing, heat setting, and rolling before use. However, in complex working conditions with special and high filtration requirements. Special production procedures are used to improve the performance and efficiency of filter bags.
Filter bags can be treated with singeing, calendaring, water and oil repellent coating, PTFE impregnation and lamination as per the specifications and demand of our customers.
