To improve the Double layer design, companies may also consider the 2.5 Layer Forming Fabric. This fabric type is an improved version of the double layer design where the weft density of the sheet side is increased. As the weft increases, the paper’s surface properties improve as well as retention and wire mark. There are different shed layer however the 8-shed and the 16-shed has the greatest potentials.

4-shed single layer polyester fabric is suitable for making culture paper, printing and packing papers etc;

5-shed single layer polyester fabric is suitable for making sanitary, culture and packing papers etc;

8-shed single layer polyester fabric is suitable for making high basic weight corrugated and packing papers etc;

7-shed double layer polyester fabric is suitable for making of high grade print paper and tissue papers;

8-shed double layer polyester fabric is suitable for making high grade print paper, offset print paper,tissue paper and board paper's surface paper,innner paper, etc;

16-shed double and a half layer fabric is suitable for making quality printing paper, tissue paper and surface paper, inner paper and base paper of the board paper, etc;

Multi-shed three-layer polyester fabric is suitable for making quality printing paper, tissue paper and cigarette paper, etc.

Example of Application:

§ Newsprint

§ Offset printing paper

§ Cigarette paper

§ Toilet paper

§ Copperplate paper

The 2.5 layer also has higher fabric support and longer life span due to the increase in the water yarn diameter and the long CD crimp. This fabric would best work for medium up to high-speed paper machine.

How to clean and maintain the polyester forming Mesh belt?

1.The main factors affecting the service life of forming mesh belt:

There are many factors that affect the life of the polyester forming fabric. It is not only affected by the forming method of the paper machine (such as Fourdrinier paper machine, net paper machine, overlapped paper machine, etc.) and paper machine technological conditions (such as dewatering element material, shape design). , Slurry type, ratio, filler type content, vacuum degree, net speed, net tension, net cleaning and fine fiber retention rate, etc.).

It is also related to the structure and type of the net itself (such as multi-wire nets, single-wire nets, single-layer nets, multi-layer nets, net thickness, etc.). Therefore, it is necessary to comprehensively consider various factors in actual production to achieve the purpose of extending the service life of the network.
