How to Choose the Right Felt for Your Paper Machine

Understand the importance of felt in papermaking.

Felt plays a critical role in the papermaking process. It is used to remove water from the paper web as it moves through the machine, and also helps to enhance the smoothness and uniformity of the paper surface. In addition, felt can affect other important factors such as press loading, drying efficiency, energy consumption, and maintenance costs. This makes it essential to choose the right type of felt for your specific paper machine and production requirements. Understanding its importance is the first step towards making an informed decision when selecting a felt.

Influenced by many factors such as paper machine conditions, paper varieties, blanket performance, etc., the adaptability of the felt to the paper machine is limited, and the requirements of the paper machine on the felt are also very strict. In order to obtain a suitable felt, it is necessary to understand the characteristics of the paper blanket and carefully and reasonably select it according to the structure of the paper machine, production conditions and the characteristics of the paper.

1. The selection of felt varieties refers to the selection of suitable for different parts among many different paper felt brands.

2. The selection of gram weight refers to the reasonable selection of the appropriate square meter gram weight according to many factors of the paper machine after the felt type is determined.

3. The determination of the length means that the actual length of the felt can meet the normal operation under the tension state of the paper machine, and the change state of the selected felt elongation should be fully considered.

4. The determination of the width means that the paper felt can meet the actual width under normal operation under tension, and the change of shrinkage rate of the selected felt should also be fully considered.

5. The selection of appropriate felt permeability is the key to determine the normal and efficient operation of the paper machine and the service life of the felt. At the same time, the change curve of the permeability of the selected felt during use should be considered.
