1, first look at the cloth surface gloss and color, and texture. According to sub-gloss, filter belt screen can be divided into long fibers and short fibers, long-fiber cloth, the surface smooth, glossy good, and the surface of the staple fiber filter belt screen with hair; classified according to the color is divided into large chemical fiber filter belt screen filter belt screen and small fiber, large fiber cloth white, shiny, and small fiber cloth dim, gray, and some such as Nomex felt filter, the color yellow; the last category is by lines, twill , plain, these lines can also help you determine the model. Because some lines of different specifications, specifications will be different. 
2, cloth fibers touch softness and texture. Some of the same cloth as soft cloth, soft materials such as cloth weaving are the same, only the thickness, density is different. There are kinds of filter belt screen is very coarse, firm, and not soft. Softness, and roughness of the sample requires you to hold a little bit of touch, write it down. Identification of additional density can touch, you can also have a few number of fixed length under the wire. The corresponding density filter belt screen specifications have their own factor, but if you can roughly identify the control. 

3, saying it is a very effective way to weight one. Mainly determine the thickness of cloth, preferably take a small piece weigh (grams per square meter). 
4, with the smoke of burning cloth to see color. One polyester black smoke burning up, burning up fat polypropylene glaucoma. Other no-burning, hard to say. 

Technology to identify a few short observations above are based on the thickness of cloth, density, and other indicators of comprehensive determination of cloth models. From the idea, we first determine whether the order is for the woven fabric, and then determine the materials, then is a long staple, do a rough texture to determine, we hope to identify the filter cloth has some help.
