China Endless Seamless Nomex & Polyester Transfer Felt Conveyor Belts, Find details about China Paper Mill Press Felt, Press Felt from Endless Seamless Nomex & Polyester Transfer Felt Conveyor Belts
The press felt plays an important role in removing the water from the paper web after the forming section, and 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 runnability.
According to the location on the paper machine can be divided into wet felts, top felt and dryer felt. The function of the wet felt is to press the raw paper to make it dehydrated and smooth the paper surface. The top felt is used above the wet felt and plays the role of leading, flattening paper and drying. Dryer felt wraps the dryer cylinder to iron and dry the pape.
Advantages of Press Felt /Paper making Felt:
1. High anti-compaction capacity.
2. Extremely high elasticity and recoverability.
3. Strong drainability and larger void volumn.
4. Smooth felt surface and even pressure distribution.
5.Long holding time of wear resistance and plastic strength of felt
