Premium Double-Layer MonoXMono Cloth for Superior Large-Format Filtration

Skytech Ultrafab 2×2 Mtr MonoXMono Double Layer Filter Press Cloth is a high-performance two-layer woven filter cloth combining a fine-retention monofilament upper layer and a coarser, open-weave monofilament drainage sublayer, fabricated for 2000 mm × 2000 mm filter press plates. The MonoXMono double-layer construction delivers the retention accuracy of fine monofilament at the filtrate-facing surface with the drainage capacity and structural support of the open sublayer — resulting in superior cake release, reduced blinding rate, and significantly extended cloth service life versus single-layer alternatives in demanding mining and chemical applications.

What Is MonoXMono Double Layer Cloth?

MonoXMono Double Layer Cloth (also called two-layer or duplex filter cloth) is a woven filter medium where two distinct fabric layers are interwoven together — the upper (cake-side) layer using fine monofilament yarn for particle retention, and the lower (filtrate-side) layer using coarser monofilament yarn for high drainage conductivity. In single-layer filter cloth, the same yarn must compromise between retention and drainage. In MonoXMono double-layer construction, each layer is optimised for its specific function — eliminating this compromise and producing a cloth with simultaneously better retention, faster drainage, and longer life than any equivalent single-layer cloth.

Features and Benefits

• Fine Retention Upper Layer: Cake-side layer woven from fine PP or PES monofilament yarn for accurate particle retention — captures the solids that single-layer coarser cloths would pass, improving filtrate clarity
• Coarse Drainage Sublayer: Filtrate-side layer woven from coarser monofilament — high open area conducts filtrate rapidly away from the cake-side layer, reducing effective pressure drop across the double-layer system
• Anti-Blinding Architecture: The drainage sublayer prevents fine particles that penetrate the upper layer from lodging permanently in the cloth depth — particles pass through to the filtrate rather than blinding the cloth interstices
• Extended Cloth Life: Double-layer construction resists the progressive blinding that limits single-layer cloth service life in applications with fine particle slurries — routine service life 2–3× longer than single-layer equivalent
• Superior Cake Release: Smooth fine monofilament upper surface minimises cake adhesion — clean, complete cake drop at each press opening without manual scraping or high-pressure washing to remove adhered cake
• 2000×2000 mm Large Format: MonoXMono double-layer construction fabricated in 2000×2000 mm plate-matched dimensions with exact feed neck, drain holes, and ear positions to the customer plate drawing

Technical Specifications

Applications

• Fine Mineral Concentrate Pressing: Copper, gold, and precious metal concentrate dewatering where sub-20 µm mineral fines would rapidly blind a single-layer cloth — double-layer construction handles fine concentrate without blinding
• Chemical Precipitate Dewatering: Titanium dioxide, barium sulphate, calcium carbonate, and fine chemical precipitate pressing where particle size distribution spans a wide range challenging for single-layer cloths
• Coal Fine Dewatering: Ultra-fine coal slurry dewatering at coal preparation plants where sub-50 µm coal fines blind standard single-layer cloths within days of installation
• Kaolin and Clay Processing: High-plasticity kaolin and clay slurry pressing where the sticky, fine nature of the material blocks single-layer cloth rapidly — double-layer drainage sublayer prevents deep penetration blinding
• Pharmaceutical and Chemical Polishing: Fine product recovery from pharmaceutical API and specialty chemical crystallisation slurries where high filtrate clarity and anti-blinding are simultaneously required

Why Choose Skytech Ultrafab for 2x2 Mtr MonoXMono Double Layer Cloth?

• Performance Advantage Justified: MonoXMono double-layer cloth commands a modest price premium over single-layer cloth — the 2–3× service life extension and production uptime gained fully justifies the cost in applications with rapid cloth blinding
• Exact 2×2 m Plate Fabrication: Double-layer cloth fabricated to the plate drawing — the two-layer construction requires particular attention to neck reinforcement and layer stability at stress points during large-format fabrication
• Proven Anti-Blinding Technology: MonoXMono construction is the established solution for fine slurry blinding in filter press applications — Skytech engineers have specified double-layer cloths across mining, chemical, and pharmaceutical applications
• Extended Campaign Intervals: Longer cloth service life reduces the frequency of cloth change campaigns at remote mine sites — significant reduction in logistics cost and press downtime for change operations
• Single-Source Large-Format Supply: MonoXMono double-layer cloth in 2×2 m format from the same manufacturer as standard single-layer cloths — consistent quality and one supplier for the complete filter press cloth programme
