What is 2.5 Layer Forming Fabrics?
2.5 Layer Forming Fabrics
The design of 2.5 layer forming fabric is fully considering about better fiber retention with good dehydration performance. The 2.5 layer forming fabric have higher fiber index than double layer forming fabric, because we add cross weave yarn on the top of double layer forming fabric to achieve this aim. It will gratelly decrease the distance between top yarn, and provide good support for small fiber. This forming fabric is good at making high grade paper.
8 Heddle 2.5 Layer Forming Fabric
The 8 heddle 2.5 layer forming fabric is normally 2.5 layer forming wire. It have high fiber support index by adding small weave on the top layer, the top weft and bottom weft ratio is 2:1.
Features 1.Good fiber support index 2.Good inner air permeability 3. Wear surface is more rough |
|
Advantages 1.Good flatness on the top layer 2.Good paper pick up and good retention function 3. Good dehydration function 4. Wear resistance and flat paper sheet surface |
|
16 Heddle 2.5 Layer Forming Fabric
This is a up 8 heddel and down 16 heddle weave technology. This structure can improve the flatness of forming fabric surface, and have higher paper sheet support function.
Features 1.The ratio of horizontal yarn to worn surface yarn is 2:1 2.Wear and tear masks have a longer free effect 3.Good internal airflow |
|
Advantgaes 1. Good paper sheet support and retation function 2. Long life service 3. Fabric weave structure wear resistance |

The 16 heddle 2.5 layer polyester forming fabric is suitable for making high-end printing paper such as offset printing book paper, copperplate base paper, news paper, cigarette paper series (forming paper, filter rod paper), toilet paper, thin paper, and board paper such as white cardboard, kraft paper. Suitable for medium and high-speed paper machines.
