Forming Fabric Paper Machine Clothing Polyester Material Wear Resistance
A sheet of paper begins in the forming section, where a mixture of 99% water and 1% cellulose fiber is introduced evenly across a forming screen/fabric, which acts as both a sheet conveyor and a dewatering device.
It is here that the paper sheet is formed and the initial water removal occurs.
As the fabric moves, water drains through it, while the fibers and fillers that form the sheet remain on top.
Today, forming fabrics have an average operating life of 45 to 60 days.
Paper machine forming screens/fabrics are designed to retain as much fiber and other furnish
components as possible while allowing water to drain through them as quickly as possible.
These fabrics are typically produced from monofilament strands or yarns that are woven together in a pattern that can be classified by their fabric style (or weave);mesh, count, and diameter; surface topography; and air permeability. This module discusses how each of these characteristics affect final sheet quality.
According to the weaving, paper making fabrics can be divided into 4-shed single layer fabrics, 5-shed single layer fabrics,8-shed single layer fabrics, 7-shed double layer fabrics, 8-shed double layer fabrics, 8-shed double and a half layer fabrics,16-shed double and a half layer fabrics.
4-shed single layer fabrics is used in making culture paper, printing paper and packing paper.
5-shed single layer fabrics is used in making printed toilet paper, culture paper and packing paper.
8-shed single layer fabrics is mainly used to making bag paper,kraft paper,sheet lined board, corrugated paper and cardboard paper etc.
1. Long service life, wear resistance, the net loss is low.
2. High fatigue resistance, acid, weak alkali resistance.
3. The mesh mark light, forming quality is good.
4. Light weight, easy to transport, set net easy operation.

1. Q: How to confirm the type?
A: There are many methods for us to confirm the type:
1). tell us the specifications data.
2).tell us your requirements as more as possible, and our engineers will give you the best suggestion and design the most suitable mesh/ wire/ fabrics/ screen/ belt.
3). send us the photos with size
4). send us a small piece sample.
2. Q: What is the payment terms?
A: We prefer T/T, but for some countries, we will also accept L/C.
3. Q: When will delivery the goods?
A: Usually, we will deliver the goods within 15 working days. And if the quantity is big, it will take about 20-30 working days.
4. Q: How long will the fabric be used?
A: The time is different differ the usage and factory. But we can confirm and make sure that our product can be used longer than any other one in China.
5. Q: Is the package strong enough for the long transportation?
A: Of course it is.
By sea, we will pack every piece into wooden box.
By air, we will pack it by strong water-proof bag.
