Single/1.5/2.5 Layer Polyester Forming Wire

Product Description

Single/1.5/2.5 Layer Polyester Forming Wire 

The polyester forming wire is used on paper machine forming section.The forming fabric acts as a conveyor and a dewatering device. As the fabric moves, water drains through it while the fibers and fillers that form the paper structure form on the top of the fabric as the paper sheet is created. lt is critical that the fabric provides a stable, durable environment to aid this process. 

Single layer:

The single layer forming fabric or "wire" of a paper machine is the continuous belt or belts of mesh screen upon which the paper sheet is formed. Most modern single layer forming fabric are comprised of polyester monofilament. The weave pattern and layering of a single layer 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.

1.5 layer:

The 1.5 layer forming fabric is actually a 5-shed single layer fabric that have modified to have extra yarns which provides it the same properties as that of a double layer one. 1.5 layer forming fabric is easy to clean, increase sheet release as well as retention and with the extra fabric provides an excellent drainage.

The ideal 1.5 layer forming fabric for most paperboard and packaging grades applications, especially where a smooth top surface and long life potential are desired. In addition, Clean mesh yarn technology provides maximum resistance to premature fabric contamination.

2.5 layer:

2.5 Layer Polyester Forming Wire Fabric is used for fourdriner wire machine ,according to the different weave ways used for different speeds of paper machine,including:single layer forming mesh belt,one and half layers forming mesh belt ,two layers forming mesh belt ,two and half layers forming mesh belt ,three layers forming mesh belt .

2.5 layer forming fabric's weaving effect greatly increases the fiber support index due to the addition of a fine weave at the top. The ratio of the top and bottom wefts is 2:1. It suitable for paperboard,newsprint,writing paper,tissue paper,printing paper,kraft paper.
