Filter Cloth

Non-woven Filter Cloth

Three-dimensional pore structure for fine-particle capture, clear filtrate and easy cake release.

Filter Cloth Series

Non-woven Filter Cloth

Non-woven filter cloth uses a three-dimensional fiber network formed by needle punching, melt blowing or thermal bonding. Unlike a woven cloth with defined yarn openings, this depth-filter structure captures fine particles through the thickness of the medium and provides useful solids-holding capacity.

Product Description

This construction is suited to sludge dewatering, mine tailings, chemical powders, pigments, electroplating residue and metallurgical slurry where fine-particle capture and dirt-holding capacity are priorities. The interconnected 3D pore structure supports clear filtrate while maintaining permeability, and the material can be adapted through fiber choice and functional treatment for different chemical conditions. Selection should consider solids loading, required filtrate clarity, cleaning method and cake behavior. Where a smooth surface and rapid, complete cake release are the primary goals, a monofilament woven cloth may be more appropriate than a depth-filter non-woven medium.
