Polypropylene nonwoven

Among the synthetic fibers, the polypropylene is lightest and easy to handle, has a temperature resistance of 90 ° C, and is excellent in acid and alkali resistance. Therefore, it is applied to the gas-solid-liquid-solid separation field where the smoke temperature is below 100 °C or the acidity and alkalinity are strong.
In the field of liquid-solid separation, polypropylene needle-punched filter felts are usually used with liquid-solid separation equipment such as plate and frame filter presses, vacuum suction filters, belt filters, and centrifugal filters. It not only has the characteristics of good dimensional stability, high strength, small elongation, but also has a smooth and smooth surface, and has pores and high gas permeability. Therefore, it also has the unique advantages of low vacuum resistance, energy saving and easy cleaning. In the beneficiation, coal preparation, petroleum, chemical and other industries, where it is necessary to filter fine particles and ensure filtration, polypropylene needle felts are far superior to traditional woven filter materials.
The polypropylene needle-punched filter felt is generally made of 2.5--6D polypropylene short fiber as the surface layer, and the middle lining is made of polypropylene yarn or polypropylene high-strength yarn. It is formed by needle-punching reinforcement, calendering and shaping.
Polypropylene needle-punched filter felt is mainly used in the field of liquid-solid separation in metallurgy, mining, petroleum, chemical, chemical fiber, medicine, food and other industries.
