        In the non-woven fabric industry, there are many kinds of non-woven fabrics that we often see. Non-woven fabrics for filter materials are commonly used. It is characterized by good filtration and strong absorption, which can be based on the different characteristics of the material. , Used in different occasions. Today we will focus on the application of non-woven filter materials in automobiles.
 
   There are many places where filter materials are needed in automobiles, such as carburetor air filtration, air conditioning cycle filtration, cabin air purification, crankcase ventilation valve filtration, engine oil filtration, transmission oil filtration, auxiliary water filtration, etc. At present, many media developed and applied for the above filtering purposes are non-woven fabrics or non-woven composite materials. For example, the circulating filter system of the air conditioning system uses electret melt-blown non-woven fabrics and active discharge composite materials. The air filter material of the carburetor is composed of chemically bonded non-woven fabric or needle punched/spunbonded fabric composite material by dry method. The transmission oil filter adopts needle-punched non-woven fabric and so on.
