Product Description

Double layer polyester forming fabric for paper making mills

Product Description

Forming wire is an important equipment on paper machine. It is a device for forming and dewatering  on paper machine. It dehydrates

the pulp suspension from the headbox and runs the paper web to the subsequent section.

Double layer forming fabric usually means that the weft yarn has a double-layer structure. Compared with single layer forming fabric, double layer have higher density for the weft and warp, strong stability, but less stretchable.
According to their weaving shed,It includes two different forms: 8-shed and 16-shed.

Structure
The structure of double-layer forming fabrics is a generally double-layer weft structure; the manufacturing method is the seamed type. Compared to single-layer, densities of warp and weft are higher. Double-layer is more dimensionally stable but less stretchable. Diameters and material types, for weft of sheet-side and machine-side, can be selected independently, enabling improvements in wire mark, two-sidedness, flatness, and fabric life. Thanks to the large three-dimensional space , our double-layer also provides excellent drainage property. Drainage force does not directly affect the paper layer, which helps improve retention and prevents fiber.

Advantages
Fine paper sheet surface giving high fiber support.
Improved forming and retention.
Improved fabric service life.
Good dimensional stability and stretching resistance.

Application
The double layer has higher warp and weft density making it more stable than the single layer. That said the double layer is less stretchable. It suitable for various paper machines,such as paperboard,newsprint,writing paper,tissue paper,printing paper,kraft paper,etc.
8-shed double layer fabric is suitable for producing quality printing paper. For example ,dictionary paper, offset printing paper,
newsprint and wrap paper. It can be used for tissue paper making and the surface pulp, lining pulp, core pulp and bottom pulp
of the board paper etc. Suitable for medium and high speed paper making machine.

16-shed double and a half layer polyester forming fabric is suitable for producing quality printing paper, such as offset printing paper,
copper plate paper, newsprint and cigarette paper series (wrap paper and filter tips paper), Also is could be used for producing toilet
paper, tissue paper and surface pulp, lining pulp, core pulp and bottom pulp of the board paper etc. Suitable for medium and high speed
paper making machine.

Installation Instructions

How to Install Forming Fabric
1. Before installing the forming wire, you should kindly check and rinse the equipment surface ,making sure it is in good condition. the surface of wires should be forbidden from unevenness, slanting, burr, sand, etc.
2. The running direction must be in accordance with the direction of the arrow on the wire.The wire should be placed in the correct position, and all rollers should be paralleled with each other to prevent the wires from being deflected.
3. There should be a high-pressure water device that can be swinging. Water pressure must be controlled in 6-10 kg/cm² for the medium and low-speed paper machine; speed more than 350m/min, water pressure is 10-15 kg/cm².When using multi-layer forming wire, water pressure is 15-30 kg/cm².Meanwhile water should be clean and without sand.
4. After putting the forming wire into paper machine, firstly check the wire,then slightly tension the wire, add water to lubricate the operation, slowly adjust the tension to normal value. Keep the tension at 3-4 kg/cm² for the low-speed paper machine, and high speed machine at 4-6 kg/cm².
