The use of fine (80 mesh) copper mesh, the lining is also fine-tuned, on the one hand to protect the surface mesh and prevent mesh deformation, maintain the filter water of the net, on the other hand, the main thing is that the net mark is lighter, the white water loss is less, the paper retains more fine fibers, so that the paper is soft.
Good control of the pressure of the roller, as light as possible, can not only improve the surface of the base paper fine, but also improve the softness of the paper.
Soft roll and boot press
The press zone of the boot press is much longer than that of the ordinary press, and the pressure distribution curve on the length of the press zone can also be adjusted by the shape of the boot.
Under the condition of fixed on-line pressure, the longer the boot press zone, the lower the peak pressure of the press zone, and reducing the pressure on the paper sheet will improve the loose thickness and softness of the paper sheet.
Soft rollers also reduce pressure.
