What are the characteristics of polyester bags?

Time : 2024-02-03 Hits : 13

The polyester bag has the following characteristics:

1. The use of high-strength and low-stretch industrial silk as the base cloth greatly improves the strength of the bag.
2. Selection of fine denier fiber manufacturing, small pore size, high porosity, high filtration accuracy.
3. Selection of high-quality polyester fiber, with acid, alkali and hydrolysis resistance.
4. The surface is smooth after treatment, with the surface filtering effect of coated filter material.
5. Small operation resistance, can save energy.


The filter material of polyester bag has high strength and good elastic recovery performance, stable fabric size, good wear resistance, large porosity, good air permeability, long service life, good dust removal effect, excellent mechanical properties, and acid and alkali resistance at room temperature (below 130℃). Due to the relatively low price of polyester, polyester bags are a cost-effective filter medium, especially suitable for low temperature environments. According to the requirements of different manufacturers for dust characteristics, polyester bags are usually added with antistatic fibers, and are treated with singeing, pressing, water and oil repellent impregnation. These treatments improve the original properties of polyester needle felt, making it easy to clean (fast dust removal), water and oil repellant (prevent dew) and antistatic properties, forming a series of products.
