Mesh lining pressing includes two methods, namely lining mesh pressing and sleeve mesh pressing.

　　1. Lining net pressing

　　Mesh pressing is the process of lining a large plastic mesh inside a pressed blanket, in order to reduce fluid pressure in the pressing area and facilitate dehydration. The use of lining mesh pressing can achieve the goal of increasing the pressure in the pressing zone, improving the dryness of wet paper width, and increasing the speed of the paper machine. However, due to the plastic mesh used for lining and pressing being packed inside the blanket, loading and unloading are more complicated and prone to damage. At the same time, the effect is limited. Therefore, it has not been widely promoted and used.

　　2. Net pressing

　　Net pressing is the process of placing a net cover on a flat pressing rubber roller or vacuum roller below, and fixing the two ends of the plastic net cover with block or whole ring pressure rings.

　　The hardness of the adhesive layer of the net roller should be slightly higher than that of ordinary rubber rollers, generally 95-96 Shore hardness, and the hardness should not be less than 88-90. If the adhesive layer is too soft, the mesh sleeve is prone to deformation. In addition, both ends of the rubber roller should be machined into a circular arc shape with a radius of no less than 12.5mm to prevent cracks or scratches on the mesh sleeve.

　　The mesh sleeve used for net pressing is made of double-layer woven single filament plastic mesh with a thickness of 2.25mm, a quantitative amount of about 900g/m2, and a void volume of about 1500cm/m. The dehydration mechanism of net pressing is basically the same as that of groove pressing. Because the mesh sleeve is made of single filament double-layer weaving, the side in contact with the blanket has enough mesh gaps to accommodate the pressed water, and the bottom layer has a channel for flowing water, so the water extracted from the wet paper during pressing is dehydrated in a vertical flow manner.
