Felt is an important paper machine spare part and is widely used in all kinds of paper making machine, such as toilet paper machine, tissue paper making machine, wet napkin making machine, a3,a4 paper making machine, kraft paper machine and corrugated paper making machine. In drying section, wire section and reeling end of paper machine, felt are an necessary part to ensure the machine to function well.
The Seam Press felt is an important role in removing the water from the paper web after the forming section, at the same time imparting smoothness and conveying it to the dryer section. For this reason, The press felt needs to provide the following functions: water removal, smoothness and runability. In recent years, larger and faster paper machines require press felts of even higher consistency and quality.

1.Water filtration
As a dewatering medium, when the paper web is dehydrated in the vacuum box and the press area, the paper making blanket absorbs and filters out the water from the paper sheet.
2.Leveling effect
In the process of web transfer and dehydration, it plays a role in leveling and modifying the paper surface
3.Function of conveyor belt
The paper sheet is transferred from the net part to the drying cadre through the pressing part, and the driven roller and cylinder mould are driven to operate.
The processing method of paper making felt is to make a thick and thin bottom cloth with synthetic fiber, and then lay a mixed fiber net of synthetic fiber and a small amount of wool, which is formed by acupuncture, chemical treatment, resin finishing and heat setting.
Paper making felt are used for paper forming, wet paper pressing, dehydration and transportation.
