Abstract:

      The micro structures of the press felt and felt-sheet system are complicated, which directly affect dewatering efficiency and quality of the sheet in modern paper machines. They have become one of the key considerations in modern paper machine system. In this paper the basic function and characteristics of press section as well as the current manufacture technology of press felt both at home and abroad were briefly introduced; and the research progress on the methods, means and achievements of the structure characteristics of press felt and the characteristics of felt-sheet system in the press section were mainly discussed. These characteristics were closely related to the dewatering efficiency and the quality of sheet. Finally, the future research trends of the press felt and the felt-sheet system were presented.
