In the screen printing industry, screen screen is used for screen printing. The mesh size is selected according to the requirements of the printed matter. "Mesh size" refers to the specification unit of the screen, which refers to the number of holes on the length of 1 inch (mm), and MM is a simple length unit. Because there are corresponding technical standards for the production of the screen, the screens of different sizes and mesh numbers have specified wire diameters, so simply speaking, the screens of different mesh numbers, The size of each hole is also different. The mesh is divided into two weaving structures, PW represents plain weave, TW represents twill, and the colors are divided into white and yellow. What are the materials of high tension silk screen fabric manufacturers?

The uniformity of the warp and weft of the nylon polyester screen is very poor, the mesh size is inconsistent, the shape is different, the surface finish is also poor, and the tension is very low. Because the quality of the screen produced by the nylon polyester screen is not ideal, the image resolution is poor, and the printing resistance is not satisfactory, so it is rarely used!

The evenness, tensile strength and surface finish of nylon screen are higher than those of cotton screen! The disadvantages are that the elongation is too large, it is easy to age and deteriorate, the light resistance is not good, and it is very easy to become brittle after long-term exposure to light!

Monofilament polyester screen is suitable for general walking screen printing plants, garment printing plants, handbag screen printing, plexiglass, plastic panels and other screen printing polyester screens. It is also made of chemical synthetic fibers and belongs to polyester screen. It has the advantages of content, high temperature resistance, water resistance and chemical and pharmaceutical resistance. When the polyester screen is subjected to large external pressure, its physical performance is stable and its tensile property is small, The disadvantage is that the wear resistance is poor compared with nylon mesh. In addition to the advantages of nylon screen printing, polyester screen is also suitable for printing printed circuit boards with high dimensional accuracy!

Nylon mesh is made of chemical synthetic fiber and belongs to polyurethane system. Nylon screen has strong abrasion resistance, chemical resistance, water resistance and elasticity. Because the silk is uniform and the surface is smooth, the ink has good passing ability! The disadvantage is that the tensile property of nylon mesh is large. The tension of this kind of mesh will be reduced within a period of time after stretching the mesh, which will relax the screen printing plate and reduce the accuracy. Therefore, it is not suitable for printing circuit boards with high dimensional accuracy!

The stainless steel wire mesh is made of stainless steel material. The stainless steel wire mesh is characterized by good wear resistance, high strength and small stretch. Due to fine wire diameter, good ink passing performance, stable mechanical performance, chemical performance and dimensional accuracy of the stainless steel wire mesh, its disadvantages are poor elasticity and high price. The wire mesh cannot be restored to its original state after stretching! Stainless steel wire mesh is suitable for high-precision printing such as circuit boards and integrated circuits!
