Long wire paper making machine double layer forming wire polyester fabric
25. Triple layer forming wire fabrics in the fourdrinier paper making machine
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 forming sixteen integrated three-layer mesh
Product characteristics: Polyester forming three-layer net is the two properties of weaving the sticker side of the net and the machine side of the net using different warp threads or the same warp threads, using different weft threads, and different weaving textures. Two different mesh layers are completely different. At the same time, the upper and lower mesh layers are connected to form a whole by the weft of the surface layer at the same time. This kind of mesh is a three-layer forming mesh. Its sticker surface is smooth and delicate, the machine surface is compact and wear-resistant, the overall structure of the net is stable, the water filtration is good, and the retention rate is high. Mainly suitable for medium and high speed paper machines to produce high-grade, high-end newsprint, cultural paper and tissue paper.
