1. What Is Woven Filter Cloth?
Industrial woven filter fiber cloth is one of the most widely used filtration media for solid–liquid and solid–gas separation across chemical processing, mining, metals, food industry, pharmaceutical production, and wastewater treatment.
Unlike nonwoven needle felt, woven cloth delivers a stable pore structure, predictable filtration performance, and excellent mechanical strength, making it ideal for equipment such as filter presses, belt filters, drum filters, disc filters, and vacuum filtration systems.
- Controlled pore size and stable filtration accuracy
- High tensile strength and dimensional stability
- Reliable cake formation and cake release
- Compatibility with corrosive or abrasive process liquids
- Long service life under thermal and chemical load
Woven filter cloth is produced by interlacing warp and weft yarns using polyester, polypropylene, nylon, fiberglass, or cotton.By adjusting yarn diameter, weave pattern, surface finishing, and physical properties, woven fabric can be optimized for clarity, flow rate, cake release, and service life in industrial operations.

Woven Filter Cloth Step-by-Step Process
4. Woven Filter Cloth Weaving & Finishing
Manufacturing high-performance woven filter cloth for industrial solid–liquid separation requires precise yarn selection, stable weaving tension, and tightly controlled finishing conditions. Every stage is monitored so that the final fabric delivers predictable permeability, cake release and mechanical strength in real filtration systems.
From warp preparation and weft insertion, through controlled weaving, heat-setting, calendering and surface finishing, our lines follow a standardized workflow to guarantee fabric stability and long service life. Each roll of cloth is woven on advanced looms, then finished, inspected and slit to width before being converted into filter panels or bags with accurate cutting, stitching and sealing—ensuring tight fit, efficient drainage and reliable operation.
① WARP PREPARATION
Opening, creeling and aligning warp yarns on the beam to guarantee constant yarn tension and a stable weaving base for the filter cloth.
② WEFT INSERTION & WEAVING
High-speed looms insert weft yarns under controlled tension, building the required weave pattern (plain, twill or satin) for the desired permeability and strength.
③ CALENDERING & SURFACE FINISHING
Calendering and surface finishing smooth the fabric, adjust thickness and air permeability, and improve cake release and resistance to abrasion.
④ SLITTING, CUTTING & CONVERTING
The finished cloth is slit to width, cut to panels or bag patterns, then stitched and sealed for easy installation in filter presses, drum filters or belt filters.
5. Woven Filter Cloth Selection Guide
01
Yarn Properties & Material Type
The performance of woven filter cloth depends strongly on the yarn material and filament characteristics. Key factors include tensile strength, abrasion resistance, chemical compatibility, moisture absorption, heat resistance, and fiber rigidity.
02
Weave Structure & Fabric Weight
Different industrial processes require specific pore structures and thicknesses. Weave types such as plain, twill, and satin directly influence clarity, cake release, strength, and permeability.
03
Finishing & Surface Treatments
Finishing treatments optimize the filtration behavior and extend fabric lifetime. Typical options include: calendering, heat-setting, singeing, anti-static treatment, oil & water repellent coating, PTFE impregnation, and membrane lamination.
04
Mechanical Strength & Dimensional Stability
A high-quality woven cloth must remain dimensionally stable during filtration cycles, pressure surges, and mechanical movement. Critical specifications include: tensile strength, elongation at break, modulus, heat-shrinkage stability, and weave tightness.
05
Process & Chemical Compatibility
Woven cloth should always be selected based on process variables such as temperature peaks, pH level, chemical concentration, abrasive solids, slurry viscosity, and oxidation intensity.

Frequently Asked Questions
Woven filter cloth is produced by interlacing warp and weft yarns in a regular pattern. It offers:
- Precise pore size and predictable permeability
- Smoother surface and good cake release
- High dimensional stability under tension
Needle-punched felt is made from randomly oriented fibres mechanically bonded by needling and is mainly used for gas-phase dust collection. Woven cloth is preferred for liquid filtration and dewatering in filter presses, belt and drum filters.
Selection is based on equipment type, temperature, pH, chemical composition, solid loading and target cake moisture. The table below gives some typical guidelines:
| Application | Recommended Woven Filter Cloth |
|---|---|
| General industrial wastewater, slurry dewatering | Polyester (PET) woven filter cloth |
| Strong acids, chemical effluents, fertiliser liquids | Polypropylene (PP) woven filter cloth |
| Abrasive slurries, mining & minerals | Nylon / Polyamide (PA) or heavy-duty PET |
| High-temperature or oxidising liquids | Fiberglass woven filter cloth |
| Food industry, sugar, starch, edible oil | Cotton or food-grade PET woven filter cloth |
Our engineering team can analyse your operating data and recommend the most suitable cloth design.
Common finishing options for woven filter cloth include:
- Heat-setting to stabilise dimensions and reduce shrinkage in operation.
- Calendering to adjust thickness, smooth the surface and control permeability.
- Surface coating to improve abrasion resistance and cake release.
- PTFE coating or membrane for ultra-low emissions and excellent chemical resistance.
- Oil & water repellent finishes for sticky or humid process conditions.
Heavier fabrics usually offer higher strength, longer service life and lower risk of mechanical damage, but may have slightly higher pressure drop.
Lighter fabrics provide higher permeability and lower initial pressure drop, which is beneficial for low-pressure or high-flow systems, but they can wear out faster.
We adjust basis weight and permeability to balance flow rate, cake moisture and cloth lifetime for each application.
Yes. All fabrics have a certain level of thermal shrinkage and elastic stretch. Heat-setting and proper tension control minimise these effects.
Typical residual shrinkage at working temperature is usually kept within 1–2% for high-quality PET, PP and PA cloths, and even lower for heat-stabilised designs.
