Abstract

The invention discloses a papermaking felt, which comprises a base layer, a fiber layer, a wear-resistant layer, a water-absorbing layer and a reinforcing layer from bottom to top, and the edges of the base layer, fiber layer, wear-resistant layer, water-absorbing layer and reinforcing layer are stacked by needle punching, The base layer is composed of the first spun yarn, the second spun yarn and the third spun yarn, and the first spun yarn, the second spun yarn and the third spun yarn are interwoven. The beneficial effects of the present invention are: simple structure, convenient use, and the reinforcing material is bamboo charcoal fiber, so that the smoothness of the wet paper web is further increased, the fiber layer can enhance the ability to squeeze water, and the durability is high. Strong, so the cotton fiber layer has high damage resistance.

Description

technical field [0001] The invention relates to a papermaking felt, in particular to a papermaking felt. Background technique [0002] Traditional papermaking felts perform the tasks of dewatering the wet paper web, increasing the smoothness of the wet paper web and transferring the wet paper web, the basic function of the felt is to balance these tasks, when the wet paper web passes between the paired press rolls , the moisture in the wet paper web moves towards the felt due to the applied pressure, and is then discharged from the back of the felt or sucked by the absorption box of the paper machine and discharged out of the felt system, therefore, the water permeability and the The function of the felt compressed by the application of pressure to recover without flattening when the pressure is released is an important feature of the felt. Felt application environments have become increasingly harsh in recent years with higher operating speeds of paper machines and higher ...
