Material

• 100% Polyester (PET) Monofilament
• Available in Hydrolysis-Resistant (HR) Polyester for high-temperature and humid environments
• Anti-Static & Anti-Adhesion Coatings (optional for reducing clogging and buildup)

Weave Types

• Plain Weave – Provides uniform filtration and good dimensional stability
• Twill Weave – Offers higher strength and better wear resistance
• Satin Weave (Broken Twill or Modified) – Improves dewatering efficiency and smoothness
• Multi-Layer Weave – Enhances durability and filtration precision (commonly used in forming and pressing fabrics)

Mesh size

The typical mesh size of polyester mesh fabric used in paper pulping varies depending on the specific stage of the pulping and papermaking process. The exact mesh size depends on factors such as pulp consistency, drainage requirements, and machine specifications. Higher mesh counts (finer mesh) provide better filtration, while lower mesh counts (coarser mesh) allow for faster drainage and higher throughput.

• Forming Fabric: 30 to 100 mesh
• Pressing Fabric: 20 to 60 mesh
• Dryer Fabric: 20 to 80 mesh
• Pulp Washing & Filtering: 40 to 200 mesh

Thread Diameter

The thread diameter of polyester mesh fabric used in paper pulping varies depending on the mesh size and application. The specific thread diameter is selected based on the required strength, permeability, and durability of the fabric in the pulping process. Finer diameters improve filtration accuracy, while thicker threads enhance durability and stability.

• Forming Fabric: 0.10 – 0.40 mm
• Pressing Fabric: 0.15 – 0.50 mm
• Dryer Fabric: 0.20 – 0.60 mm
• Pulp Washing & Filtering: 0.08 – 0.30 mm

Fabric Thickness

The appropriate thickness is selected based on factors such as drainage efficiency, mechanical strength, and resistance to wear. Thicker fabrics provide better durability, while thinner ones offer improved permeability and dewatering performance.

• Forming Fabric: 0.50 – 2.50 mm
• Pressing Fabric: 1.50 – 4.50 mm
• Dryer Fabric: 1.00 – 3.50 mm
• Pulp Washing & Filtering: 0.30 – 2.00 mm

Open Area (%)

• Forming Fabric: 15 – 35%
• Pressing Fabric: 8 – 25%
• Dryer Fabric: 5 – 20%
• Pulp Washing & Filtering: 10 – 40%
• Note: A higher open area improves drainage and dewatering efficiency.

Air Permeability (m³/m²·h or CFM)

• Forming Fabric: 2000 – 8000 m³/m²·h
• Pressing Fabric: 500 – 3000 m³/m²·h
• Dryer Fabric: 200 – 1500 m³/m²·h
• Pulp Washing & Filtering: 500 – 7000 m³/m²·h
• Note: Air permeability affects water drainage, drying efficiency, and sheet formation quality.

Tensile Strength (N/cm or MPa)

• Warp Direction (MD): > 250 – 1500 N/cm
• Weft Direction (CD): > 150 – 1200 N/cm
• Note: Tensile strength depends on fabric thickness, thread diameter, and weaving structure.

Density (Threads/cm)

• Forming Fabric: 20 – 60 threads/cm
• Pressing Fabric: 10 – 40 threads/cm
• Dryer Fabric: 5 – 30 threads/cm
• Pulp Washing & Filtering: 15 – 80 threads/cm
• Note: Higher thread density improves dimensional stability and filtering precision.

Roll Dimensions

• Width: 0.5 – 10 meters (customizable)
• Length: 20 – 100 meters per roll (or as required)
• Note: Rolls are produced according to customer requirements for machine compatibility

Available Colors

• Blue (Most common for easy contamination detection)
• White (Standard industrial use)
• Green (Enhanced UV resistance for outdoor exposure)
• Yellow (Customized for visibility and tracking)
• Black (Optional for high-wear applications)
