In the non-woven fabric industry, filter materials are one of its important uses. Due to the simple processing and high filtration efficiency of non-woven filter materials, it has formed a huge impact on industries such as traditional textile filter materials and paper filter materials. As the global demand for masks continues to grow, non-woven filter material is an important raw material, and its performance testing and quality testing have also become important links before marketing. As a professional non-woven testing organization, Byrne Testing has organized the following testing knowledge of non-woven filter materials in accordance with relevant standards.
Non-woven filter materials can be divided into two types: dry type and wet type. Dry filtration is the separation of floating or suspended solid particles in gas or dust in the air, that is, gas-solid separation, which is called bag filtration in industrial production. The bag filter is generally needle punched non-woven filter material. Wet filtration is the separation of floating or suspended solid particles in liquid, that is, liquid-solid separation. The filter cloth is used in various types of filters.
