In the non-woven industry, we often see many kinds of non-woven fabrics. Non-woven fabrics for filter materials are commonly used. It is characterized by good filterability and strong absorption, and can be based on different characteristics of the material. , Used in different occasions. Today we will focus on the application of non-woven fabrics for filtering materials in automobiles.

There are many places in the car that require filtering materials, such as carburetor air filtration, air conditioning circulation filtration, cabin air purification, crankcase ventilation valve filtration, engine oil filtration, transmission oil filtration, and auxiliary water filtration. At present, many media developed and applied for the above-mentioned filtration purposes are non-woven fabrics or non-woven composite materials. For example, the circulating filtration system of air conditioning systems uses electret meltblown nonwovens and active discharge composites. The carburetor air filter material consists of a chemically bonded non-woven fabric or a needle punched / spun bonded fabric composite material by a dry method. Needle-punched non-woven fabrics are used for transmission oil filters.
