Product Description

2.5 Layer Forming Fabric for Paper Making Machine

Forming Fabric / Forming Wire

The forming fabric or "wire" of a paper machine is the continuous belt or belts of the 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 the 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 a seam. During the weaving 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. On the other hand, the filaments of paper machine cross direction are called weft 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.

4-shed single layer forming fabric is a standard type of polyester forming fabric in paper making, mainly used for producing cultural paper printing paper, packing paper and so on.
5-shed single layer forming fabric is suitable for making healthy, culture and packing papers, etc.
8-shed single layer forming fabric is the most wear-resisting one in the single-layer screen, which has long performance life, but mesh print is relatively deep. It is mainly used for copying papermaking bags, craft paper, cardboard, corrugated paper, and so on.
7-shed double layer forming fabric is suitable for quality printing paper and tissue paper etc.
8-shed double layer forming fabric is suitable for quality printing paper, tissue paper, and the surface pulp and inner pulp of the board paper, etc.
8-shed, 16-shed double a half layer forming fabric is suitable for making quality printing paper, tissue paper and surface pulp, inner pulp and base pulp of the board paper, etc.
Multi-shed three-layer forming fabric suitable for making quality printing paper, tissue paper, cigarette paper, etc.

Paper Machine Press Felt

Paper Machine Felt, Press Felt, Pick Up Felt


Paper making felt includes: Press felt, BOM felt, MG felt, Pick up felt, Shoe press felt, Combi Press Felt, Seamed felt.
The paper-making felt are of good adaptability, smooth surface, low steam consumption, long life and a fine water-filtering 
performance, which makes the paper a superfine surface.

Paper making felt Working Principle:
In the press section of a paper machine, water is removed from the newly formed sheet. The paper sheet is carried by a 
press fabric between two rolls, where water is removed with the application of pressure.  also can be assisted by the use of a vacuum and heat.

The press felt plays an important role in removing the water from the paper web after the forming section, and at the same time imparting smoothness and conveying it to the dryer section. For this reason, the press felt needed to provide the following functions: water removal, smoothness, and runnability. In recent years, larger and faster paper machines require press felts of even higher consistency and quality. At Huatao, we seek uniformity in every aspect of the production process. Using digital controls, we are able to manage the entire process with great precision and implement a high level of quality control in all aspects.

 

Dryer Fabric / Dryer Screen

Dryer Screen, Dryer Fabric, Dryer Canvas

Dryer screens can be classified depending on weaving structure can be divided into WOVEN type and SPIRAL type.
The flat yarn spiral dryer screen is composed of flat wire, the surface dryer screen is smooth, depending on the filling yarn added to the spiral dryer screen, air permeability range from 100 to 1380 CFM.
We have launched a new flat yarn woven dryer screen, which is a unique two-tier flat warp weave screen with controlled permeability, recommended for Unirun positions and high-speed machines. The higher surface contact area helps to increase the heat transfer with better sheet support thus lowering energy consumption.

Round yarn is a woven dryer screen made from high-grade round monofilament polyester yarns.
According to the category, a round yarn is a woven dryer screen that can be divided into one and a half layers, double layers,s, and rectangular wire fabric. According to the joining mode, it can be divided into insert, pin, pin ring, and spiral ring joint.

Woven Dryer Screen
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.

Spiral Dryer Fabric
Polyester Spiral Dryer Screen Mesh is widely used in producing paper, corrugated paper, and paper for train fare, and also used in filtration and sieving in environmental protection, pharmaceutical, mine, metallurgy, machinery, airspace, and other fields.

Advantages of Polyester Spiral Belt :
1. Flat surface, not easily cracked, Good air permeability
2. Stable property against heat and moisture
3. Low thermal shrinking, Less elongation at heat, Long lifespan

FAQ

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

1. Before installing the forming wire, kindly check the equipment if 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 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).
