Durability & Efficiency
Multi-Filter Compatible
NHD filter cloth is widely used across industries including ore beneficiation, coal washing, chemical processing, pharmaceuticals, and food production. It is compatible with a broad range of filtration equipment, such as vertical filter presses, belt vacuum filters, chamber filter presses, plate and frame filter presses, rotary table vacuum filters, disc filters, rotary disc vacuum filters, and centrifuges —— using PP, polyester, or nylon, with key parameters including thickness, air permeability, breaking force, filtration fineness, grammage, and acid/alkali resistance.
Produced using advanced technology and backed by decades of filtration expertise, NHD filter cloth supports continuous-duty filtration with easy cleaning, strong dimensional stability, high productivity, and long service life. In 2023, NHD contributed to the revision of an industry standard for woven filter cloth used in chamber filter presses and plate-and-frame filter presses.
Twisting yarn
Filter cloth made from twisted yarn has a firm structure, good filtration performance, and a long service life.
Warping
The high-tension warping machine provides precise control of yarn and beam tension, ensuring a smooth weaving process.
Weaving
Our specialized looms are imported from Germany, providing high beating force and uniform weaving tension for consistent product quality.
Setting
Heat setting is a critical step in filter cloth production. Our specialized heat-setting process effectively controls fabric deformation and ensures stable performance during use.
Calendering
Calendering improves filter cake release and filtration precision. Our high-pressure calendering process applies uniform pressure across the fabric width, ensuring consistent filtration precision and air permeability.
Cutting
Professional cutting equipment ensures precise edge trimming, helping prevent filter cloth misalignment during operation and extending service life.
Beating-up
Treatment of filter cloth joints and edges to ensure their quality and extend the service life of the filter cloth.
Brush coating
Treatment of filter cloth joints and edges to ensure their quality and extend the service life of the filter cloth.
Inspection
Before shipment, finished products undergo strict testing for key performance parameters, including weight, thickness, density, filtration precision, tear strength, and air permeability.
Packaging
Proper packaging protects filter cloth quality during transportation. Lightweight or short-distance shipments use dense woven packaging for waterproofing and damage protection, while heavier or long-distance shipments use pallets or crates.
