Difference between polypropylene long-fibre and short-fibre filter cloths

Polypropylene long fibre and staple fibre are two kinds of yarn categories, long fibre includes monofilament and multifilament, and staple fibre is made by twisting to make the staple fibre embrace; the main difference lies in the filtration performance, cloth surface characteristics and service life.

1. Filtration Performance

Polypropylene long-fibre filter cloth: smooth surface, good air permeability, good abrasion resistance, easy to peel off the filter cake, easy to clean. Because of its smooth surface, the particles are not easy to adhere, so it is more suitable for the filtration scene that needs high efficiency and air permeability.

Polypropylene short fibre filter cloth: short fibre, cloth surface with hair, strong ability to retain small particles. However, due to the hairy surface, particles are easy to adhere to it, and the peeling and air permeability are slightly worse than filament, so it is more suitable for filtration scenarios that require high-precision retention of particles.

2. The Characteristics of The Cloth

Polypropylene long-fibre filter cloth: woven by filament yarns, the cloth surface is smooth, lightweight and less burdensome to the equipment.

Polypropylene short fibre filter cloth: short fibres through the spinning process of twisting the fibres to hold together, the cloth surface with hair, the texture is relatively heavy.

3. Service Life

Polypropylene long-fibre filter cloth: due to its good wear resistance, and the smooth surface of the cloth is not easy to clog, so the service life is relatively long.

Polypropylene short-fibre filter cloth: although its ability to retain small particles, but because of the cloth surface with hair, easy to clog, and poor peeling, so the service life is relatively short.

To sum up, when choosing polypropylene filter cloth, we should choose suitable long or short fibre filter cloth according to the specific filtration requirements and working conditions.

In the production process, we strictly follow the process, and each process is carefully tested to ensure that each batch of products, each filter cloth meets the quality testing standards.
