Dipped Fabric for Conveyor Belts: The Essential Reinforcement Layer for High-Performance Conveyor Systems
In the world of heavy-duty material handling, the strength and durability of a conveyor belt depend largely on what lies beneath its surface. At the heart of every high-tensile conveyor belt is dipped fabric — a specially treated textile reinforcement that provides structural integrity, impact resistance, and dimensional stability.
As a professional dipped fabric for conveyor belts manufacturer, we produce high-quality dipped fabrics (also known as dipped canvas or dipped polyester/nylon fabric) that meet international standards for mining, aggregate, cement, steel, and port handling industries.
What Is Dipped Fabric for Conveyor Belts?
Dipped fabric is a woven textile (typically made from polyester, nylon, or a blend like EP — Polyester/Nylon) that undergoes an immersion process in an adhesive solution, usually based on resorcinol-formaldehyde-latex (RFL). This dip treatment ensures:
Strong adhesion between the fabric and rubber compound
High resistance to heat, moisture, and microbial attack
Minimal stretch under high tension
Improved fatigue resistance
Without high-quality dipped fabric, even the best rubber compounds will delaminate or fail prematurely.
Types of Dipped Fabric We Manufacture
Our product line covers the most common specifications used in conveyor belt construction:
| Fabric Type | Material | Best For |
|---|---|---|
| EP Dipped Fabric | Polyester warp + Nylon weft | General-purpose belts, long-distance conveying, low elongation requirements |
| NN Dipped Fabric | 100% Nylon | High-flex applications, small pulley diameters, impact-prone areas |
| CC Dipped Fabric | Cotton or cotton-poly blend | Light-duty belts, low-temperature environments, economical options |
| Straight Warp Dipped Fabric | High-tenacity polyester/nylon | High-modulus belts, steel cord alternative, heavy impact resistance |
Why Choose Our Dipped Fabric for Conveyor Belts?
1. Superior Adhesion Strength
Our RFL dipping process ensures that the fabric bonds tightly with rubber layers, preventing ply separation even under continuous flexing.
2. High Tensile & Low Elongation
Using premium polyester and nylon yarns, our dipped EP fabrics provide excellent dimensional stability — essential for long-center conveyors.
3. Customizable Widths & Weave Patterns
We offer widths from 500 mm to 3000 mm, and weaves including plain, twill, and straight warp to suit different belt carcass designs.
4. Heat & Chemical Resistance
Specially formulated dip solutions can be tailored for heat-resistant (up to 180°C) or oil/MR (moderately resistant) applications.
5. Factory-Direct Quality Control
Every roll is tested for adhesion (N/mm), breaking strength (N/mm), and elongation at break (%) before shipment.
Applications of Dipped Fabric-Reinforced Conveyor Belts
Mining: Heavy ore, coal, and overburden handling
Steel plants: Sinter, pellet, and slag conveyors
Cement: Limestone, clinker, and raw meal belts
Port terminals: Ship loading/unloading of grains, fertilizers, and minerals
Quarries and aggregates: Stone, gravel, and sand conveyors

Frequently Asked Questions (FAQ)
Q: What is the difference between EP and NN dipped fabric?
A:
EP fabric has low elongation and high heat resistance (better for long
belts). NN fabric is more flexible and fatigue-resistant (better for
short, high-impact belts).
Q: Can you customize the adhesion level?
A:
Yes. We can adjust the RFL dip formulation to meet specific adhesion
requirements for different rubber compounds (natural rubber, SBR,
neoprene, etc.).
Q: Is your dipped fabric suitable for steel cord conveyor belts?
A:
Dipped fabric is used as a breaker or transverse reinforcement in some
steel cord belts, but primarily it serves as the main carcass for
fabric-reinforced belts.
Q: Do you provide free samples?
A: Yes, we offer free A4-size samples and a technical data sheet for qualification testing.
