Filtration is one of the industrial processes that require great care and attention. During the separation process, filter cloths are used. In the filtration process with filter presses, the solid and liquid parts must be separated from each other. It works with the principle of separating the clean liquid part by keeping the solid materials in the filter cloths.
In the filtration process, the function of the filter cloth and the equipment used becomes very important. In separation processes, filter cloths directly affect the quality of the process. When it comes to filtration, the function of the filter cloth and the equipment used becomes very important.
Filter cloths have the feature that determines the quality of the filtration process. Details such as the yarn type of the filter cloths and the weaving technique of the cloths play an important role in the filtration processes. Processes made according to details such as yarn type and weaving technique will also vary.
Depending on many details, such as the filter press plate and the substances to be separated, the preferred filter cloths may vary. It is possible to have information about filter cloths according to the yarn type and weaving technique.
Filter Cloths in terms of Thread Type
In terms of yarn type, filter cloths can be listed as monofilament yarn, multifilament yarn and staple fiber.
Monofilament Yarn
Filter cloths made with monofilament yarns have a smooth and slippery surface. Thanks to the monofilament threaded filter cloths, the cake dropping process is carried out very easily. However, filter cloths with monofilament threads are not successful in holding very small particles. Therefore, it is not suitable for use in processes with small particles.
Multifilament Yarn
Multifilament filament filter cloths consist of a lot of fiber. Therefore, it provides long-term use. However, clogging may occur due to the slime between the fibers.
Staple Fiber
The surface of filter cloths with staple fiber yarn is wide. Its wide surface is capable of preventing even very small particles. However, it is necessary to consider the possibility of clogging of filter cloths with staple fiber threads.
Filter Cloths in Terms of Weaving Technique
In terms of weaving technique, filter cloths are listed as plain, twill and satin.
Plain
Plain is the simplest of weaving techniques. The filter cloths woven with this technique have a high particle holding capacity.
Twill
The filter cloths woven with the twill weaving method form a diagonal structure, so they are very successful in leaving cakes. Compared to the plain method, its durability and particle holding capacity are insufficient.
Satin
Filter cloths woven with satin weaving technique have a slippery and shiny structure. The cake is very comfortable to leave and is long lasting. For this reason, it is often preferred.
