Polyester dryer fabric is a specialized industrial fabric designed for efficient solid/liquid separation and sludge dewatering. It is primarily used in vacuum and multi-roll belt presses, as well as in paper drying processes. The fabric undergoes precise heat-setting under controlled temperature and tension conditions to ensure maximum operational stability. With its unique spiral weave patterns, it offers rapid drainage and excellent cake release, making it an ideal choice for various industrial applications.

Classification

Polyester dryer fabric can be categorized based on weaving patterns, mesh structure, and connection types:

By Weaving Pattern:

• Three-shed weave: This weave pattern provides a balance of strength, stability, and permeability, making it suitable for a wide range of drying applications, particularly for lighter papers under 70 grams. It is often used in one-and-a-half-layer configurations.
• Four-shed weave: Offering enhanced stability and durability, this weave is ideal for heavier applications and demanding drying conditions, especially for papers weighing more than 70 grams. It is commonly used in double-layer constructions.

By Mesh Structure:

• Single-layer: This lightweight and cost-effective construction is suitable for applications where basic drying performance is required.
• One-and-a-half-layer: This configuration, often employing a three-shed weave, offers improved stability and runnability compared to single-layer fabrics, providing a balance of performance and cost for lighter papers.
• Double-layer: Typically utilizing a four-shed weave, this construction provides the highest level of stability, durability, and performance, ideal for demanding applications, heavier papers, and high-speed drying processes.
• Flat dryer mesh: This structure provides a smooth and uniform drying surface, improving paper quality and minimizing surface imperfections. It is particularly beneficial for applications requiring a high-quality finish.

By Connection Type:

• Inserting Type
• Slotting Type
• Slotting Ring Type
• Spiral Ring Connecting Type

By Specific Applications:

• 4106 Round Thread Screen: Suitable for thin paper with a weight under 60 grams.
• Flat Thread Screen: Designed for specialized drying applications requiring smooth texture and high stability.
