Nowadays there are many ways to filter, and the fabric system is also widely used. Needle punched non-woven fabric is one of the filter materials, which belongs to a fabric medium. It is commonly used in some industrial sectors, such as electronics, food, oxygen production, medicine, etc., as well as the requirements of hotels in terms of air dust and sanitation, mainly to lay low concentration dust particles. Then, as a fabric medium, the filter needle punched non-woven fabric often needs to be accompanied by high temperature. How much can it withstand high temperature?
Generally, the high temperature resistance of needle punched non-woven filter fabric can only reach about 120 ℃ - 130 ℃. If it is operated beyond this range for a long time, its strength will be lost, and it will shrink greatly, which will change the size of filter material, thus affecting the filtering effect. Therefore, if a higher temperature is required, it is necessary to further improve the function on the original basis to form a high temperature resistant filter needle punched non-woven fabric.
