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. In recent years, larger and faster papermachines require press felts of even higher consistency and quality. At Ichikawa, we seek uniformity on every aspect of the production process. Using digital controls, we are able to manage the entire process with great precision, and to implement a high level of quality control on all aspects.

 

The press section is the next part of the paper machine after the forming section.The most important functions of pressing are to increase sheet solid consistency in order to ensure adequate drying capacity, to consolidate the sheet, and enable web runnability in the early dryer sections.Increased sheet consistency increases wet strength and improves sheet consolidation and fiber-to-fiber bonding which increases sheet strength. This typically improves runnability and reduces press to dryer draw.

 

Pressing can also have a significant impact on quality parameters such as smoothness, ink absorption, bulk, and moisture profile. The fabrics in this section are called press fabrics or press felts. The term “fabric” has a broader meaning; “felt” is a type of fabric which is made of individual fibers only, i.e., no yarn in the fabric structure. Nevertheless, the terms “press fabric” and “press felt” are used interchangeably in papermaking. Although it depends on sheet grade and paper machine, typical sheet consistency at the beginning of the press section is 20% fiber and 80% water and at the end of the press section is 45% fiber and 55% water. At the end of the press section, the sheet is transferred to the dryer section.
