Twill Dutch Weave Wire Mesh Manufacturer

Twill Dutch Weave Wire Mesh

For fine-grade filtration where both cut-point precision and mechanical durability are paramount, Anping CREMOTIVE Wire Mesh Products CO., LTD supplies Twill Dutch Weave Wire Mesh. The Twill pattern—where each warp wire passes over two (or more) consecutive weft wires before under two—creates a diagonal rib effect that stabilizes the fine wires and enhances open-area uniformity.

Twill Pattern Characteristics

• Over-Under Sequence: Common configurations include 2/2 (over two, under two) and 3/2 (over three, under two), enabling mesh counts from 50 × 10 to 200 × 40 wires per inch.

• Diagonal Appearance: The ribbed diagonal lines facilitate controlled deformation, allowing mesh to flex under load without altering aperture size.

• High Open-Area: Diagonal offsets open up spaces between wires, achieving open-areas up to 40 % even at fine cut-points.

Material Processing
316L stainless steel wire is preferred for chemical and temperature resilience; 304 wire offers cost-effective performance in non-aggressive settings. Wire-drawing, crimping, and weaving steps mirror those of plain Dutch weave but require precision loom adjustments to maintain the correct over-under sequence. Finished mesh is annealed, pickled, and passivated to ensure full alloy performance.

Performance Advantages

• Enhanced Throughput: Compared with plain Dutch weave of similar cut-point, twill weave typically yields 5–10 % higher open-area, reducing pressure drop.

• Deep Filtration: Multi-layer twill constructions can be designed—coarser layers upstream, finer layers downstream—to capture a range of particle sizes in a single element.

• Resistance to Vibration: The diagonal crimp pattern dampens vibration-induced wire movement, ideal for ultrasonic cleaning systems and high-velocity flows.

Use Cases

• Pharma Clarification: Retention of sub-20 µm particulates during API recovery processes.

• Fine Chemicals: Catalyst removal in slurry reactors, protecting downstream ultrafiltration membranes.

• Food Polishing: Final clarification of edible oils, fruit juices, and beer at cut-points between 10 µm and 50 µm.

• Gas Filtration: Dust-particle removal in flue-gas stacks and compressed-air systems.

Supply Formats
We provide rolls, panels, and cylindrical elements up to 2 m in width. Mesh counts and wire gauges are specified to match target cut-points and flow requirements. Each mesh is supplied with a certificate of compliance, detailing aperture measurements, open-area ratio, and tensile properties.
