Filter Cloth

Nylon PA Filter Cloth

High elasticity and superior abrasion resistance for slurry containing hard particles.

Filter Cloth Series

Nylon PA Filter Cloth

Nylon (PA) filter cloth is designed for abrasive slurry and repeated mechanical loading. Its elasticity, toughness and wear resistance suit mineral, quartz, ceramic and pigment filtration at continuous temperatures up to 100°C, but it is not recommended for concentrated strong-acid service.

Continuous working temperature≤100℃

Transient temperature110℃

pH resistance5～11 (weak alkali resistant; poor resistance to concentrated strong acid)

Filtration precision8～50 μm

Weave typePlain / twill / satin weave, heat-set finished

Product Description

The polyamide yarn is selected for mechanical endurance in quartz sand, abrasive ore, ceramics, calcium carbonate, pigments and neutral or weak-alkaline non-ferrous mineral pulp. High elasticity lets the fabric recover after repeated compression, while fiber toughness resists scouring and impact from hard solids. Plain, twill and satin constructions cover filtration grades of approximately 8–50 μm at continuous temperatures up to 100°C. The stated pH range is 5–11, and concentrated strong acid can weaken the material. Before ordering, examine the location of previous cloth failures, particle hardness, edge contact and plate condition; tears caused by burrs or installation wrinkles will not be corrected by material strength alone.
