Why Polyester Filter Cloth?

Abstract: This paper mainly talks about the meaning of polyester filter cloth, the characteristics, uses and application fields of polyester short fiber filter cloth and flame retardant polyester.

First, meaning

Polyester filter cloth refers to the filter material made of polyester fiber. Polyester filter cloth is divided into polyester long fiber filter cloth, polyester short fiber filter cloth and flame retardant polyester.

Second, characteristics

Performance of polyester short fiber filter cloth:

Acid-resistant, alkali resistant, wear-resistant, corrosion-resistant, good recovery, poor conductivity. The temperature resistance of polyester fiber is generally 130-150 ℃. In addition to the unique advantages of ordinary felt filter cloth, the product has very good wear resistance and high-cost performance, so it has become the most widely used type of felt filter material.

Flame retardant polyester properties:

It has permanent flame retardancy and a wide range of applications. In addition to being used in textiles, interior decoration of buildings and interior decoration of vehicles, it also plays a lot of roles in the field of protective clothing

Third, use

Polyester is widely used in food manufacturing and industrial products.

According to the national standard of flame retardant protective clothing, the departments of metallurgy, forestry, chemical industry, petroleum and fire protection should use flame retardant protective clothing. The number of people who should use flame retardant protective clothing in China is more than one million, and the market potential of flame retardant protective clothing is huge. In addition to pure flame retardant polyester, according to the special requirements of users, we can produce flame-retardant, waterproof, oil repellent, antistatic and other multi-functional products. For example, waterproof and oil repellent finishing of flame-retardant polyester fabric can improve the functionality of flame-retardant clothing; using flame-retardant polyester and conductive fiber to interweave to produce antistatic flame-retardant fabrics; using flame-retardant fiber and high-performance fiber to interweave to produce high-performance flame-retardant fabrics; using flame-retardant fiber to mix with cotton, viscose and other fibers to improve the comfort of protective clothing, while reducing Second burn. So it is widely used in pharmaceutical, sugar, food, chemical, metallurgy, industrial filter press, centrifuge and so on.
