Non-Woven Filter Cloth

High-Performance Filtration for Industrial Applications

Non-Woven Filter Cloth is a highly efficient and durable filtration material designed to meet the diverse needs of industrial and commercial filtration processes. Made from synthetic fibers bonded through mechanical, chemical, or thermal processes, non-woven filter cloth provides superior filtration efficiency, chemical resistance, and mechanical strength. Whether used in liquid-solid separation, dust collection, or air filtration, non-woven filter cloth ensures optimal performance across multiple industries.

What is Non-Woven Filter Cloth?

Non-Woven Filter Cloth is a fabric-like material composed of synthetic fibers that are randomly arranged and bonded using needle punching, heat treatment, or resin bonding techniques. Unlike woven fabrics, non-woven filter cloth has no regular interlacing pattern, allowing for higher permeability, uniform filtration, and improved dirt-holding capacity.

Non-woven filter cloth is widely used in industries requiring effective filtration solutions, including wastewater treatment, food processing, pharmaceuticals, and chemicals.
