Features

The filter cloth is a very important component of the filter press, and whether the filter press can work ideally depends largely on the performance of the filter cloth and its ability to achieve solid-liquid separation without blockage or damage. Filter cloth can be divided into two categories based on fiber material. One category is natural fibers such as cotton, wool, silk, and hemp fibers; Another type is chemically synthesized fibers, such as polyester, nylon, polyacrylonitrile, vinylon, acrylic, polyester fibers, etc. According to the yarns that make up the filter cloth, it can be classified into mono-filament yarn, multi-filament yarn, and short fiber yarn. The characteristic of filter cloth woven from single fibers is that it is not easily clogged and has good cake unloading performance. The characteristics of multi-filament filter cloth are high tensile strength, good cake unloading and regeneration performance. The characteristics of short fiber yarn filter cloth are good particle retention performance and the sealing performance it can provide. The filter cloth woven from mono-filament yarn is called "mono-filament fabric"; The filter cloth woven from multi-filament or short fiber yarn is collectively referred to as "multi-filament fabric".

The filtration performance of filter cloth made by different weaving methods varies:

Filtration rate: plain weave filter cloth<twill weave filter cloth<satin weave filter cloth<non-woven filter cloth;

Moisture content of filter cake: plain weave filter cloth>twill weave filter cloth>satin weave filter cloth>non-woven filter cloth;

Filtrate transparency: plain weave filter cloth<twill weave filter cloth<satin weave filter cloth<non-woven filter cloth;

Unloading performance: non-woven filter cloth<plain filter cloth<twilll filter cloth<satin filter cloth;

Regenerative performance: satin filter cloth<twill filter cloth<plain filter cloth<non-woven filter cloth;

Service life: non-woven filter cloth<satin filter cloth<plain filter cloth<twill filter cloth;
