Polyester 2.5layer Forming Mesh Paper Making Fabric With High Fatigue Strength

Long wire paper making machine double layer forming wire polyester fabric

Polyester forming wire is a commonly used dewatering equipment in the papermaking industry. Early use of copper mesh, it is a new product gradually developed with the social progress and rapid development of science and technology and adopted by the paper industry. It was originally a single-layer polyester forming mesh, and is now gradually replaced by a multilayer forming mesh. It is mainly made of polyester monofilament and nylon monofilament through fine weaving. At present, weft- or warp-connected three-layer forming net is a series of multi-layer nets continuously developed by our company in recent years. It is not only suitable for medium and low speed The loom produces medium and low-end paper products, and can also be used for high-speed paper machine production and high-quality paper products. In particular, we added wear-resistant threads in the middle of the weft and adjusted the net structure to make the characteristics of the polyester forming net more prominent. It has long service life, wear resistance, aging resistance, low net consumption, and high fatigue strength.

There are many factors that affect the service life of polyester forming fabrics. It is not only affected by the forming method of papermaking machines (such as fourdrinier machines, folder paper machines, stack paper machines, etc.), and the technical conditions of paper machine processes (such as mechanical equipment, Material, shape design, slurry type, mix ratio of various materials, content of filler type, vacuum degree, net speed, net tension, high pressure water, fine fiber retention rate, etc.

Polyester 2.5layer forming mesh

Product characteristics: Sixteen healds and two layers of semi-formed netting are based on the original two layers of knitting method using eight healds to support the weft on the sticker surface, which can greatly improve the retention of fibers and fillers. The laminating surface adopts a monofilament with a larger diameter as the bottom weft, and adopts a large-span double warp weft pressing method of a group of sixteen healds, which increases the stiffness of the net, increases the bottom weft arc, and improves The contact surface with the dewatered original of the paper machine increases the abrasion resistance of the net and prolongs the service life of the net. It is suitable for medium and high speed paper machines to make cultural paper, electrostatic copy paper, double adhesive paper, and low basis weight copperplate. Paper, cup paper, face screen, backing screen and bottom screen of laminating machine.
