Waterproof And Antistatic Polyester Needle Punched Felts

A needle punched felt is made from webs or batts of fibers in which some of the fibers have been driven upward or downward by barbed needles (Figure 1). This needling action interlocks fibers and holds the structure together by friction forces. The phases of needle punching process are shown in figure 2. 

Polyester waterproof and antistatic needle felt  are mainly used in chemical industry, metallurgy, food, pharmaceutical, building materials, mining and other industries bag dust collector.

After the concentration of dust reaches a certain degree, such as electrostatic discharge spark or external ignition and other factors, it is easy to cause explosion and fire, such as surface dust, chemical dust, coal dust and so on, waterproof and antistatic needle punched felts are developed.
