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.

Rows of yarn spools on a twisting frame

Twisting yarn

Filter cloth made from twisted yarn has a firm structure, good filtration performance, and a long service life.

Warp threads drawn onto a beam

Warping

The high-tension warping machine provides precise control of yarn and beam tension, ensuring a smooth weaving process.

Loom weaving the filter fabric

Weaving

Our specialized looms are imported from Germany, providing high beating force and uniform weaving tension for consistent product quality.

Heat-setting the woven cloth over a roller

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.

Cloth passing through calender rollers

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.

Cloth cut to width on the line

Cutting

Professional cutting equipment ensures precise edge trimming, helping prevent filter cloth misalignment during operation and extending service life.

Reed beating up the weft on the loom

Beating-up

Treatment of filter cloth joints and edges to ensure their quality and extend the service life of the filter cloth.

Brush-coating station with finished rolls

Brush coating

Treatment of filter cloth joints and edges to ensure their quality and extend the service life of the filter cloth.

Operator inspecting cloth at a test station

Inspection

Before shipment, finished products undergo strict testing for key performance parameters, including weight, thickness, density, filtration precision, tear strength, and air permeability.

Wrapped rolls staged for packaging

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.
