Woven Nylon (PA) Filter Cloth for Solid-liquid Separation
Nylon, also known as polyamide (PA), is a class of polymer materials linked by amide bonds. Depending on their molecular structure, common varieties include PA6, PA66, PA610, and PA612. Nylon woven filter cloth is a high-performance filtration material widely used in solid-liquid separation. Woven from high-strength nylon monofilaments or multifilaments, it offers excellent filtration efficiency, abrasion resistance, and chemical corrosion resistance, meeting the demands of diverse industrial filtration applications.
Description
☑ Exceptional Acid & Alkali Resistance
Demonstrates outstanding chemical stability, enabling long-term, reliable performance in challenging acidic or alkaline environments.
☑ High-Efficiency Filtration
Engineered with uniform pore structures to precisely retain fine impurities and solid particles, ensuring clear filtrate quality.
☑ Low Resistance & High Flux
The ultra-thin profile significantly minimizes filtration resistance, delivering higher flow rates and lower energy consumption under identical pressure.
☑ High Mechanical Strength & Wear Resistance
Boasts exceptional tensile strength and unmatched abrasion resistance, making it ideal for high-frequency, high-intensity mechanical filtration.
☑ Smooth Surface for Easy Cake Discharge
The flat woven surface ensures smooth filter cake release, while facilitating effortless backwashing and cloth regeneration to extend service life.
01. Monofilament Polyamide (PA) Filter Cloth
- Great permeability of air and water.
- Less jam possibility.
- Filter cake can be easily released and recycled.

02. Multifilament Polyamide (PA) Filter Cloth
- Great strength,especially its anti-abrasion is top-ranked in all general fibers.
- Resist strong alkali and weak acid.
- The strength expense can be ignored after dealt with NaoH(10%),as Polyamide is used 16h in the state of 90℃.
- It’s continual applied temperature within 120℃and the instant applied temperature can be up to 150℃.
- PA 66 can not be applied in the field of Pharmacy and Food industry.
