In many industrial fields such as metallurgy, chemical engineering, and food, filter cloth, as a core material for solid-liquid separation and dust purification, plays a crucial role in enhancing production efficiency and ensuring product quality. This filter medium, woven from natural or synthetic fibers, is adapted to different working conditions through a variety of materials and processes.

Common filter cloth materials each have their own emphasized characteristics. Polyester filter cloth is acid-resistant and wear-resistant, with a temperature resistance range of 130 to 150℃. Its short-fiber variety fabric is dense and has good particle retention, making it suitable for fine filtration scenarios such as pharmaceuticals and sugar making. Long-fiber varieties have a smooth surface, good air permeability, and are more convenient for cleaning and cake removal. Polypropylene filter cloth is renowned for its excellent acid and alkali resistance. The double-layer monofilament type, after calendering treatment, has low filtration resistance and is widely used in sludge dewatering, tailings dry discharge and other fields. Moreover, its service life is longer than that of traditional filter cloth. Nylon filter cloth has outstanding wear resistance and is an ideal material choice for the rubber industry. However, some models are not suitable for the food and pharmaceutical fields due to their characteristic limitations.

The performance of the filter cloth is closely related to its selection. A comprehensive judgment should be made based on the filtration accuracy, operating temperature and acidic or alkaline environment: polyester material can be given priority in high-temperature scenarios, while vinylon filter cloth is suitable for strongly alkaline environments. Meanwhile, maintenance measures such as flat installation, regular cleaning and control of filtration pressure can effectively extend its service life.

From the perspective of textile technology, after heat shrinkage and calendering treatment, the filtration efficiency and durability of monofilament filter cloth are significantly improved, which can meet the high-precision filtration requirements of 0.005μm and above, and is highly favored in industries such as non-ferrous metal smelting. This multi-dimensional adaptability makes filter cloth an indispensable basic material in industrial production.
