Huatao Group has a professional technician team that devoted to pulp and paper industry. We are able to make the best proposal after completely analyzing and figuring our problems of the paper production line though paper-making progress, equipment, electric automatization and so forth.
The forming fabric / Forming wire or "wire" of a paper machine is the continuous belt or belts of mesh screen upon which the paper sheet is formed. Most modern forming fabrics are no longer comprised of metal wires. Rather, they are comprised of polyester monofilament. The weave pattern and layering of a forming fabric is designed to meet stringent requirements of dimensional stability, resistance to abrasion (on the wire side), minimum resistance to drainage, minimum wire mark, and (sometimes) maximization of retention of fiber fines. Traditional Fourdrinier paper machines have a single wire. Modified Fourdriniers and gap formers can have two.
Forming fabric is very important for a paper machine in a paper mill. In the general formation of paper depends on wire cloth and refining of paper pulp. Paper machine wire cloth (forming fabric) made from polyester or polyamide monofilaments. To shape an uninterrupted belt, it is made by endless of a seam. During woven of forming fabric, filaments are composed of the paper machine direction and paper machine cross direction. The filaments of paper machine direction or lengthwise are called warp. One the other hand the filaments of paper machine cross direction are called weft or Shute or filling. The construction of wire cloth depends on some weaving variables such as pattern, mesh, yarn, diameter, degree of crimping etc. Mesh is very important for a wire cloth (forming fabric). Water drainage and retention of fibers depend on it.
According to the category, forming fabric can be divided into single layer wire cloth, 1.5 layer wire cloth, double layer wire cloth, two and a half layer wire cloth, triple layer wire cloth, and 2.5 layer wire cloth.
In accordance with weaving, wire cloth (forming fabric) can be divided into 2-shed, 4-shed, 5-shed, 7-shed, 8-shed, 16-shed, 24-shed etc. A paper machine wire cloth has two surfaces. One is the forming surface or top surface and another is the wearing surface or underside surface.
Depending on paper machine and various paper grades wire cloth also difference. The uses of triple layer wire cloth (forming fabric) is increasing day by day.
How to choose the right forming fabric for your paper machine?
Forming fabric design based on different machine type, operation speed, paper grade. So please provide us your paper machine information as details as possible.
How to Install Forming fabric
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 the rollers should be paralleled with each other to prevent the wires from being deflected.
3. There should be a swinging high-pressure water device that used to wash wire. Water pressure is not lower than 6-10 kg/cm² for the medium and low-speed paper machine; speed more than 350m/min, water pressure is not lower than 10-15 kg/cm²; When using multi-layer forming wire, water pressure is not lower than 15-30 kg/cm², meanwhile water should be clean and without sand.
4. When installing the forming wire, firstly let the wire be slightly tensioned, add water to lubricate the operation, adjust the tension to normal after sizing, keep the tension of the low-speed paper machine at 3-4 kg/cm², and high speed one at 4-6 kg/cm².
Packing & Shipping
1. Bubble Film and waste thick fabric wrapping while protecting inside fabric.
2. Wrapped special fabric package outside (Air shipping ).
3. Composite wooden box (seashipping).

Long lifespan
Woven Dryer Screen
According to the weaving, polyester dryer fabric can be divided into 3-shed, and 4-shed. According to the category, polyester dryer fabric can be divided into one and a half layer, double layer, and rectangular wire fabric. According to the joining mode, it can be divided into insert, pin, pin ring and spiral ring join. 3-shed one layer and a half polyester dryer fabric are suitable for drying papers below 70g. 4-shed double layer polyester dryer fabric is suitable for drying papers above 70g. Rectangular wire polyester dryer fabric is suitable for the fore several heating boxes of the drying zone, quality papers can use all.
Press felt / paper making felt / BOM felt / Seam felt / Seamed felt / Endless felt / Pick up felt
There are three series of BOM papermaking felts available in the market. They are single-layer base mesh, double-layer base mesh and multi-layer base mesh. According to their structures, they can be divided into BOM formed felt, BOM pressed felt, BOM upper felt, BOM
dryer felt, BOM pulp board felt, and so on.
BOM paper-making felts are generally made of the base mesh layer and the fiber layer. The base mesh can be single, double, or multi-layers. The double base mesh
layer can also have a 1+1 laminated. The multi-layer base mesh can also be divided into 1+2 or 2+2 laminated. All mesh bases are woven with monofilament or twisted monofilament yarns. The fiber layers are woven with different sizes of polyamide fibers. Fiber layers and base mesh layer are attached by needle stitching to form the felt
