Fiber Shedding From Paper Machine Felt

When you install a new press felt on your paper machine, the paper machine felt was not running so long but occurs fiber (batt) lose. Why does this phenomenon occur?

Causes of Paper Machine Felt Fiber Shedding

There are several reasons for the occurrence of fiber loss or rapid wear on the back of the paper machine felt, including the following:

• The design of the paper machine felt is unreasonable or the needling density is insufficient.
• The press felt is too dry when it run on the paper machine.
• The storage time of felts is too long.
• There is a speed difference between the paper machine felt and the guide/press roller (the felts has low tension and slips).

How to Prevent Paper Machine Felt Fibers From Shedding?

So when you get a new paper machine felt, do not store it too long time, and when install a new press felt on your machine, we need avoid felt too dry when it’s running on the paper machine. It is necessary to adjust the speed ratio of each transmission point of the paper machine correctly to ensure that there is no abnormal speed difference.
