Non Woven Fabric Polypropylene

Among the synthetic fibers, non woven fabric polypropylene is the lightest and easy to handle, with a temperature resistance of 90 ° C and excellent acid and alkali resistance. Therefore, it is used in the field of gas - solid - liquid - solid separation with smoke temperature below 100 ℃ or strong acidity and alkalinity.

In the field of liquid - solid separation, polypropylene needle punched filter felts are usually equipped with liquid - solid separation equipment such as plate and frame filter presses, vacuum suction filters, belt filters, centrifugal filters, etc. Not only has the characteristics of good dimensional stability, high strength, small elongation, etc., but also its surface is smooth. Polypropylene non woven material has porosity, high permeability, so it also has the unique advantages of low vacuum resistance, energy saving, and easy cleaning. In the fields of mineral processing, coal preparation, petroleum, chemical industry, etc., where tiny particles need to be filtered and filtration is guaranteed, polypropylene non woven fabric rolls are far superior to traditional woven filter materials.

PP non woven felt generally uses 2.5 -- 6 D polypropylene staple fiber as the surface layer, which is lined with polypropylene yarn or polypropylene high - strength yarn base fabric. It is made by needle punching reinforcement and calendering, shaping and other post - treatment processes.
Polypropylene needle punched filter felt is mainly used in the field of liquid - solid separation in metallurgy, mining, petroleum, chemical industry, chemical fiber, medicine, food and other industries.
