There are many factors affecting the service life of polyester forming net, which are not only affected by paper machine forming methods (such as long screen paper machine, web clamping paper machine, web folding paper machine, etc.) and paper machine technological conditions (such as dehydration component material, shape plan, pulp type, proportion, filler type content, vacuum degree, mesh speed, tension of the net, consumption of the net, etc.). The influence of retention rate of micro fibers is also related to the layout and example of polyester forming net (such as multiple wire mesh, single wire mesh, single layer mesh, multi-layer mesh, mesh thickness, etc.). Therefore, many factors should be considered comprehensively in the actual production to reach the goal of extending the life of the net.

Generally speaking, the important factors affecting the service life of polyester forming net are power consumption, water filtration rate and the operation usage of paper per ton. In the process of using polyester forming net, depending on the above three factors, the service life of polyester forming net can be determined accurately, which is conducive to the planned organization of production.
