In the non-woven fabric industry, there are many types for customers to choose from and the non-woven polypropylene filter fabric is one of the most commonly used ones. It is characterized by its excellent filter capability and strong absorption property. Different kinds of polypropylene non-woven filter fabrics have different uses, as the scope of their application is not quite the same. For example, cotton filter fabric mainly uses the swelling of cotton fiber, which is suitable for collecting fine dust. However, due to their perfect filtering properties, almost all of the non-woven polypropylene filter fabrics are popular and widely used.
Nonwoven polypropylene filter fabric, composed of directional or random fibers, is a new generation of environmental protection materials. This kind of NWPP fabric is moisture-proof, breathable, flexible, light in weight, easy to decompose, non-toxic and non-irritating, colorful, cheap, and recyclable.
Polypropylene non-woven filter fabric is a kind of fabric that does not need to be spun. The fabric has no warp and weft threads. It is very convenient to cut and sew, light, and easy to shape. That is the reason why the polypropylene non-woven filter fabric is preferred by many handicraft lovers.
There are many places in the car that need filter materials, such as carburetor air filtration, air conditioning circulation filtration, carriage air purification, crankcase ventilation valve filtration, engine oil filtration, transmission oil filtration, auxiliary water filtration, etc. At present, media developed and applied for filtration purposes are polypropylene non-woven filter fabrics and their composite materials. For example, the circulating filtration system of the air conditioning system uses electret meltblown non-woven fabric and active discharge composite materials.
