Fabric conveyor belts are widely used in mining, cement plants, quarry industries, ports, power plants, recycling plants, and bulk material handling systems. Choosing the correct conveyor belt material is very important for improving production efficiency, reducing maintenance problems, and increasing belt service life.
Among different types of fabric conveyor belts, polyester conveyor belt and nylon fabric conveyor belt are two of the most commonly used options in industrial applications. Both types have strong performance advantages, but they are suitable for different working conditions.
At Monster Belting, we manufacture high quality fabric conveyor belts for different industries and conveying environments. Our belts are designed for excellent tensile strength, abrasion resistance, flexibility, and stable operation in heavy duty applications.
In this article, we will compare polyester and nylon fabric conveyor belts in detail, including their structure, performance, applications, advantages, and maintenance requirements.
What Are Fabric Conveyor Belts?
Fabric conveyor belts are industrial belts reinforced with textile fabric layers. These belts are used for transporting bulk materials, minerals, coal, aggregates, sand, cement, fertilizer, and many other industrial products.
The main structure of fabric conveyor belts includes:
- Top rubber cover
- Fabric reinforcement layers
- Bottom rubber cover
- Adhesion rubber between fabric plies
The fabric layers provide strength and flexibility, while the rubber cover protects the belt from abrasion, impact, heat, oil, and wear.
The most common fabric types include:
| Fabric Type | Common Name | Main Material |
|---|---|---|
| EP | Polyester conveyor belt | Polyester and polyamide |
| NN | Nylon fabric conveyor belt | Nylon fabric |
| CC | Cotton conveyor belt | Cotton fabric |
Among these options, polyester conveyor belt and nylon fabric conveyor belt are the most popular for industrial applications.
Understanding Polyester Conveyor Belt
A polyester conveyor belt is also known as an EP conveyor belt. The warp direction uses polyester fiber while the weft direction uses polyamide fiber.
This structure gives the belt excellent dimensional stability and strong impact resistance.
Main Features of Polyester Conveyor Belt
- High tensile strength
- Low elongation
- Good dimensional stability
- Excellent abrasion resistance
- Strong adhesion with rubber
- Suitable for long distance conveying
- Good moisture resistance
Because of these features, polyester conveyor belt is widely used in heavy duty industrial conveying systems.
Understanding Nylon Fabric Conveyor Belt
A nylon fabric conveyor belt is made using nylon fibers in both warp and weft directions.
Nylon fabric provides very good flexibility and impact resistance. These belts are commonly used in applications where heavy impact loading occurs.
Main Features of Nylon Fabric Conveyor Belt
- Excellent flexibility
- High impact resistance
- Good troughability
- Strong fatigue resistance
- Suitable for short and medium conveying distance
- Good performance under dynamic load
Nylon fabric conveyor belt is commonly used in mining and quarry applications where materials fall from height onto the belt.
Main Difference Between Polyester and Nylon Fabric Conveyor Belts
Although both are fabric conveyor belts, there are important performance differences between them.
Comparison Table
| Features | Polyester Conveyor Belt | Nylon Fabric Conveyor Belt |
|---|---|---|
| Fabric Type | Polyester + Polyamide | Nylon |
| Elongation | Low | Higher |
| Dimensional Stability | Excellent | Good |
| Impact Resistance | Good | Excellent |
| Moisture Resistance | Better | Moderate |
| Flexibility | Moderate | Excellent |
| Troughability | Good | Very Good |
| Long Distance Conveying | Excellent | Good |
| Heavy Impact Applications | Good | Excellent |
| Maintenance Requirement | Lower | Moderate |
Tensile Strength Comparison
Tensile strength is an important factor when selecting fabric conveyor belts.
Polyester conveyor belt has very stable tensile strength and low stretch during operation. This makes it suitable for long conveying systems where stable tracking is important.
Nylon fabric conveyor belt also has high strength, but it can stretch more under tension. Because of this, additional take up adjustment may be required during operation.
For industries requiring precise belt movement and stable tension, polyester conveyor belt is usually preferred.
Impact Resistance Comparison
Impact resistance is very important in mining, quarry, and stone crushing industries.
Nylon fabric conveyor belt performs better under heavy impact conditions because nylon fibers have excellent elasticity and shock absorption properties.
For example, when transporting:
- Large rocks
- Iron ore
- Copper ore
- Stone aggregates
- Coal lumps
Nylon fabric conveyor belt can better absorb the impact force.
Polyester conveyor belt also has good impact resistance, but nylon belts are generally stronger in this area.
Elongation and Stability
One of the biggest advantages of polyester conveyor belt is low elongation.
Low elongation provides several benefits:
- Stable belt tracking
- Reduced maintenance
- Better operational efficiency
- Lower take up adjustment
- Improved long distance conveying
Nylon fabric conveyor belt has higher elongation compared with polyester conveyor belt. During long term operation, the belt may require additional tension adjustment.
For conveyor systems with long center distance, polyester conveyor belt is often the better choice.
Flexibility and Troughability
Nylon fabric conveyor belt has excellent flexibility and troughability.
This means the belt can easily form a trough shape around conveyor rollers. Better troughability helps improve material carrying capacity.
Industries handling bulk materials often prefer nylon fabric conveyor belt because of this advantage.
Polyester conveyor belt also has good flexibility, but nylon belts are generally softer and more adaptable in curved conveyor systems.
Moisture Resistance Performance
Moisture resistance is important in wet working environments.
Polyester conveyor belt has better moisture resistance compared with nylon fabric conveyor belt.
Nylon material absorbs more moisture, which may affect belt performance in some wet conditions.
For applications such as:
- Wet sand conveying
- Port terminals
- Outdoor bulk handling
- Humid environments
Polyester conveyor belt is often preferred.
Abrasion Resistance
Abrasion resistance determines the service life of fabric conveyor belts.
Both polyester conveyor belt and nylon fabric conveyor belt can achieve excellent abrasion resistance when combined with high quality rubber covers.
At Monster Belting, our fabric conveyor belts are available with different rubber grades including:
| Rubber Grade | Application |
|---|---|
| DIN X | Heavy abrasion applications |
| DIN Y | Medium duty conveying |
| DIN W | Highly abrasive materials |
| Heat Resistant | High temperature materials |
| Oil Resistant | Oily material conveying |
| Fire Resistant | Flame resistant applications |
The correct rubber cover selection is equally important as fabric selection.
Applications of Polyester Conveyor Belt
Polyester conveyor belt is suitable for many industrial applications.
Common Applications
- Cement plants
- Steel plants
- Power plants
- Port terminals
- Sand processing plants
- Recycling plants
