What is a press felt:
Press felt is essential equipment in paper production and are used for paper shaping, transportation and dehydration. The base fabric is made of synthetic fiber, covered with a blended fiber mesh of synthetic fiber and a small amount of wool. After the base mesh is shaped, it is made through processes such as needle punching, final product shaping, and edge cutting and edge sealing. Can be divided into single-layer, double-layer and triple-layer press felt.
Advantage:
Characteristics of paper making press felt:
1.Paper making press felt has strong resistance to pressure.
2.Good water filtration performance and small elongation.
3.Light traces and easy to clean.
4.Excellent elasticity and recovery, long service life and other advantages.
5.Helps improve productivity and quality and reduce maintenance costs.
paper making press felt application:
Change the bottom wire structure according to different paper machines and different papers.
Single layer press felt: kraft paper,package paper,white paperboard etc...
Double layer press felt:writing paper,corrugated paper, newspaper etc...
Triple layer press felt: big roll press, tissue paper, coating white board etc...
