Polyester mesh, also known as polyester mesh. Polyester mesh has the advantages of solvent resistance, high temperature resistance, water resistance, chemical resistance, etc., and has low stretchability and stable physical properties. Compared with nylon mesh, the disadvantage is that the wear resistance is poor, and it is suitable for printing prints with high dimensional accuracy.
The opening degree of the screen is used to measure the size of the mesh, which is the width of the mesh, and is expressed by the square root of the mesh area enclosed by the warp and weft of the net. If the horizontal and vertical bidirectional meshes are the same, the opening degree indicates the length of one side of the mesh. Therefore, the longer the length of one side of the mesh, the larger the opening degree.
The aperture ratio of the screen, also called the screen through-hole ratio, the effective sieve area, the percentage of the mesh area, etc., is the percent
age of the mesh area per unit area of the screen.
After the wire mesh is stretched on the frame, the wire diameter is elongated by the tension. The data shows that the higher the mesh number, the greater the relative tensile elongation.
The screen is stretched under the tension, causing the wire diameter of the screen to become thinner, and the mesh number and opening degree of the screen are changed.
Polyester printing mesh is also called polyester mesh. Polyester mesh has the advantages of solvent resistance, high temperature resistance, water resistance, chemical resistance, etc., and has low stretchability and stable physical properties. Compared with nylon mesh, the disadvantage is that the wear resistance is poor, and it is suitable for printing prints with high dimensional accuracy.
