As one of the paper machine clothing and an important equipment in the drying section of the paper machine, the dryer fabric can not only support the transportation effect during the drying stage, but also filter the water of the paper web to complete the forming. The dryer mesh can be divided into spiral dryer fabric, round yarn dryer fabric and flat yarn dryer fabric. Sun Hong can customize different specifications and rings for you according to your needs.
Responsibilities of the dryer fabric in paper production:
The wet paper will pass through the pressing section, where the water will be filtered out by pressing and further dried. Then, it will be transported to the drying section with the dryer fabric. The dryer fabric will stick the wet paper to the surface of the drying cylinder and prevent the paper from being displaced and wrinkled. The water will be evaporated by heating the drying cylinder. In addition, the excellent air permeability of the dryer fabric can accelerate the evaporation of water in the paper and make it more uniform, effectively improving the flatness of the paper and the uniform distribution of tension. After being dried by multiple groups of drying cylinders, the paper reaches the required degree of dryness, and the subsequent dryer fabric will guide the paper to the next process.
(1) Sun Hong’s spiral dryer fabric is made of polyester ring spiral wires that are intertwined and filled with filling wires. It has good service life, air permeability and stability. It is suitable for paper machines such as cultural paper, packaging paper, and corrugated paper.
(2) Round yarn dryer fabric is made of round polyester fiber with uniform diameter and regular mesh. Round wire dryer fabric has moderate air permeability, wear resistance and pressure resistance. Due to its round structure, it is not easy to accumulate dust and is easy to clean. It is suitable for paper machines such as newsprint, cultural paper and corrugated paper.
(3) The flat yarn dryer fabric is made of flat polyester fiber. This structure has a large contact area, good dewatering effect and strong stability. It can be used for paper types with high surface finish and high strength, such as high grade cultural paper.
In terms of air permeability, spiral dryer fabric has the best air permeability, round yarn dryer fabric has the second best air permeability, and flat yarn dryer fabric has lower air permeability than the first two.
In terms of wear resistance, spiral dryer fabric and round yarn dryer fabric have better wear resistance and are suitable for frequent use. Flat yarn dryer fabric is not as good as the first two in wear resistance, but has the best dimensional stability and support, and flat yarn dryer fabric has the best wear resistance. The large surface area contact of the mesh can improve the surface quality of the paper, while the spiral dryer fabric and flat yarn dryer fabric are suitable for paper types that do not require high surface quality.
In addition, it should be noted that the seams of the dryer fabric are prone to paper dryer fabric marks. Reducing the tension of the dryer fabric, reducing the large wrap angle of the dryer fabric or the large bend path can effectively avoid it. (Or changing the type of dryer fabric seam can also avoid this problem)
As the largest paper machine clothing supplier in northern Jiangsu, Sun Hong produces a full range of dryer fabric. It can customize different specifications and different rings (small ring, medium ring, large ring) according to your needs. It has professional and advanced production equipment and experienced technicians to provide you with various support.
