There is a professional international mesh reference table corresponding to metal mesh and non-metallic mesh in the silk screen industry. The appearance of this table is very friendly to those who have just entered the industry as a reference. We have also talked about the origin of mesh in the previous article. The so-called nylon filter mesh actually refers to the number of mesh holes in 2.54cm (i.e. 1 inch) You want to see the mesh size of the screen, for example, 180 mesh refers to 2.54cm in which there are 180 mesh. The mesh size of the mesh directly determines the fineness of the filtering items. If the mesh size is small, the filtering effect is general. If the mesh size is large, the filtering material will be very fine. How do people know the mesh size of the mesh? Is it true to go to a mesh to count? The answer is of course not. There are professional textile density mirrors for measuring mesh size. As long as you use the correct density mirror, you can get the correct mesh size. This kind of textile density mirror can measure the density of warp and weft. When measuring, place the mesh to be measured flat on the table, and then take out the density mirror and place it parallel to the direction to be measured, Observe the mesh size displayed. The value you see is the mesh number of this measurement object. It can not only be used on the filter screen yarn, but also is an indispensable and important measuring tool in cotton and linen silk screen printing, nylon polyester, metal stainless steel, copper mesh and other industries.
