How to improve the initial adaptability of press felt

1. Reasonable selection of the air permeability of the press felt is not conducive to the production of the paper machine.

2. Reasonably formulate the production process of press felt, and obtain the ideal felt performance by adopting the reasonable needling process, water washing, pressure setting process, the structure proportion of the felt, the thickness and thickness of the layer fiber and the layer amount.

3. After the new felt is put on the machine, the initial adaptation time of pressing the felt can be shortened by properly applying a certain pressure during idling, adding hot water at about 50 ° C for expansion, adding about 5% alkaline water for softening, and introducing about 0.1MPa steam into the Yankee dryer for hot pressing.
