This type of conveyor belt uses fiber fabric as the core and general rubber as the covering material, with a smooth and flat surface (Figure 1). The core is a layered or integral fabric woven from fibers such as cotton, nylon, polyester, or vinylon.
Cotton fiber is the earliest used core material and is easy to bond with rubber. Its strength slightly increases when wet, but its breaking strength is low (mostly around 56 N/(mm · layer)), and its anti-corrosion and mildew resistance is poor. Its use is gradually decreasing.
Starting from the late 1950s, nylon fiber fabrics were used as core materials and have become the most widely used type. Nylon fiber has a strength of up to 700 N/(mm/layer), is water-resistant, corrosion-resistant, and resistant to bending fatigue; but the elastic elongation is relatively large.
Polyester fiber has similar properties to nylon fiber, but its elastic elongation during use is only half that of nylon fiber, making it a promising material for development. Vinylon fiber has a strength of 200 N/(mm · layer), a smaller elastic elongation than nylon fiber, is easy to bond with rubber, and has good heat resistance. However, its strength decreases by 10–25% when wet, and it is only used in a few countries such as China and Japan. When weaving the core, only one type of fiber can be used, or two types of fibers can be blended or interwoven.
ℹ️ Supplementary Information
Ordinary conveyor belts are divided into many specifications and models according to different usage environments and requirements:
- According to the size of transportation volume and width, it is divided into commonly used models such as B300 B400 B500 B600 B650 B800 B1000 B1200 B1400 B1600 B1800 B2000 (B represents width, in millimeters).
- According to different usage environments, it is divided into models such as heat-resistant conveyor belts, cold resistant conveyor belts, acid alkali resistant conveyor belts, oil resistant conveyor belts, food conveyor belts, etc. The minimum thickness of the covering adhesive on ordinary conveyor belts and food conveyor belts is 3.0mm, and the minimum thickness of the lower covering adhesive is 1.5mm; the minimum thickness of the covering adhesive on heat-resistant, cold resistant, acid alkali resistant, and oil resistant conveyor belts is 4.5mm, and the minimum thickness of the lower covering adhesive is 2.0mm. Depending on the specific usage environment, the thickness of the upper and lower covering adhesives can be increased by 1.5mm.

❓ Frequently Asked Questions
What materials are used in the production of general conveyor belts?
General conveyor belts are refined from all cotton canvas (CC) or nylon (NN) / polyester (EP) through processes such as rolling, forming, and vulcanization. The core material options include polyester cotton interwoven fabric (TC-70 type) and all cotton canvas (CC-56 type).
What bandwidth sizes are available for general conveyor belts?
General conveyor belts are available in bandwidths ranging from 300mm to 3000mm, covering common models such as B300, B400, B500, B600, B650, B800, B1000, B1200, B1400, B1600, B1800, and B2000, where "B" represents the width in millimeters.
What are the key differences between cotton, nylon, and polyester fiber cores?
Cotton fiber is easy to bond with rubber but has relatively low breaking strength (~56 N/mm·layer) and poor mildew resistance. Nylon fiber offers high strength (up to 700 N/mm/layer), is water- and corrosion-resistant, but has larger elastic elongation. Polyester fiber performs similarly to nylon but with only half the elastic elongation, making it more dimensionally stable during use.
What is the temperature operating range for the new material general conveyor belt?
The new material general conveyor belt can operate continuously in a temperature range of -73°C to +260°C, making it suitable for both high and low temperature industrial environments.
What quality standards does the general conveyor belt comply with?
The general conveyor belt is manufactured in accordance with the GB/T7984-2001 standard. Key performance requirements include tensile strength ≥ 15 MPa, tensile length at break ≥ 350%, wear amount ≤ 200 mm³, and interlayer bonding strength ≥ 3.2 N/mm between layers.
What types of special-purpose conveyor belts are available?
Based on specific application needs, conveyor belts are available in a wide range of types including oil resistant, anti-skid, climbing, acid and alkali resistant, heat resistant, cold resistant, flame resistant, corrosion-resistant, moisture-proof, low-temperature resistant, high-temperature resistant, and flame retardant conveyor belts.
