The chemical name of vinylon filter cloth is polyvinyl alcohol. Its strength is lower than that of polyester, its elasticity is poor, the shape retention of fabric is poor, but its wear resistance is better, and its durability is 1-2 times that of pure cotton.

Advantages: it can withstand the action of strong alkali, and has good hygroscopicity. It is easy to combine with rubber. It is a good material for rubber industry.

Disadvantages: low temperature resistance, shrinkage when the temperature reaches 100 ℃, and acid resistance.

Application: used in the factory or rubber industry with strong alkaline material.

(2.) Polyester Filter Cloth

Polyester filter cloth is resistant to high temperature, it has the special advantages of common felt filter cloth, and it has very good wear resistance. It has a high cost performance and becomes the most used filter cloth in felt filter material.

Advantages: acid resistance, weak alkali resistance, wear resistance, corrosion resistance, good recovery

Disadvantages: poor peeling and air permeability

Application: pharmaceutical, sugar, food, chemical, metallurgical, industrial filter press, centrifuge, etc.

(3.) Nylon filter cloth

According to the test, the wear resistance of nylon fiber is 10 times of that of cotton fiber and 50 times of that of viscose, which ranks first in many kinds of fibers. Therefore, nylon filter cloth is a high wear-resistant filter cloth.

Advantages: nylon filter cloth is resistant to strong alkali, weak acid and wear.

Disadvantages: nylon filter cloth is not light resistant, easy to change color and brittle, so it is not suitable for long-term exposure to the sun.

Application: rubber, ceramics, pharmaceutical, food, metallurgy, etc.

(4.) Polypropylene Filter Cloth

Long polypropylene fiber filter cloth has smooth surface and good air permeability;short polypropylene fiber filter cloth has wool surface, and the effect of powder filtration and pressure filtration is better than that of long fiber.

Advantages: polypropylene filter cloth has good acid resistance, alkali resistance, wear resistance, good conductivity, slightly better recovery than polyester.

Disadvantages: poor corrosion resistance.

Application: chemical, ceramic, pharmaceutical, smelting, manufacturing, beneficiation as filter cloth.
