Teach you how to differentiate between industrial pressed felt products

Paper machine pressed felts are essential components of the papermaking process. These felts help to transfer, press, and dry the paper during production. However, not all paper machine pressed felts are created equal. Different types of felts have unique properties that affect their performance in the papermaking process. In this article, we will teach you how to differentiate between paper machine pressed felt products based on their composition, structure, and intended use.

Here is the content list:

• Composition of press felt

• Structure of press felt

• Intended use of press felt

Composition of press felt

The composition of paper machine pressed felts refers to the materials used to make them. Felts can be made from synthetic fibers, wool, cotton, or a blend of these materials. Each material has its unique properties that affect the performance of the felt.

Synthetic fibers such as polyester, nylon, and polypropylene are commonly used in the production of paper machine pressed felts. These fibers are known for their durability, resistance to wear and tear, and high-temperature resistance. Wool felts, on the other hand, are known for their softness, flexibility, and absorbency. Cotton felts provide good cushioning and absorbency.

By understanding the different properties of these materials, you can choose the right felt for your specific papermaking needs. For example, if you need a felt for a high-speed paper machine, you may want to choose a synthetic felt that is more durable and can withstand high temperatures. If you need a felt for a paper machine that produces delicate paper, you may want to choose a wool felt that is softer and more flexible.

Structure of press felt

The structure of paper machine pressed felts refers to the arrangement of the fibers within the felt. Felts can have different structures such as single-layer, multi-layered, laminated, needled, or calendared. The structure affects the density, thickness, and surface finish of the felt.

Intended use of press felt

Different types of paper machine pressed felts are designed for specific applications in the papermaking process, such as forming, pressing, and drying. For example, pick-up felts are used to transfer the newly formed sheet from the forming section to the press section, whereas dryer felts are used to absorb moisture from the paper during the drying process.

By considering the composition, structure, and intended use of the felt, you can differentiate between different types of paper machine pressed felts.
