Needle Felt Filter Bags

Description

Needle felt filter bags are common filter materials, usually used for liquid or gas filtration in industrial fields. They are made of synthetic fibers such as polyester and polypropylene through a needle punching process and have high filtration efficiency and durability. The structural feature of this filter bag is that the fibers are needle-punched into groups during processing to form a three-dimensional network structure, which makes the filter bag have better filtration performance and mechanical strength. They are widely used in chemical industry, food processing, pharmaceutical and other fields, and can be used to remove suspended particles, sediments, bacteria, etc.
