The 2.5 layer forming fabric is a high performance forming fabric. Compared with 1.5 and single layer forming fabric, the 2.5 layer forming fabric provides higher uniformity, wear resistance and water filtration performance, and is often used in high speed paper machines. The design of Sun Hong's 2.5 layer forming fabric takes into account higher fiber retention without affecting water filtration. By adding transverse weaving wires on the top of the forming fabric and reducing the distance between the top wires, it can provide better support for fine fibers.
(1) Sun Hong adopts a multi layer design to increase the support points while making the fiber distribution more uniform
(2) The bottom support and surface fiber are designed independently, with excellent water permeability
(3) It can effectively reduce fiber marks and surface defects, and improve paper quality and appearance
(4) The structure is stable and suitable for high speed paper machines, reducing downtime and replacement frequency
The 2.5 layer forming fabric is suitable for paper making of high weight and high quality paper grades (packaging paper, special paper, etc.), especially paper grades with high requirements on paper surface.
