This type of conveyor belt uses fiber fabric as the core and general rubber as the covering material, with a smooth and flat surface. The core is a layered or integral fabric woven from fibers such as cotton, nylon, polyester, or vinylon.
Cotton Fiber: The earliest used core material, easy to bond with rubber. Strength slightly increases when wet, but breaking strength is low (mostly around 56 N/(mm·layer)), and anti-corrosion and mildew resistance is poor. Its use is gradually decreasing.
Nylon Fiber: In use since the late 1950s, now the most widely used type. Strength up to 700 N/(mm/layer), water-resistant, corrosion-resistant, and resistant to bending fatigue. Elastic elongation is relatively large.
Polyester Fiber: Similar properties to nylon fiber, but elastic elongation during use is only half that of nylon fiber — a promising material for development.
Vinylon Fiber: Strength of 200 N/(mm·layer), smaller elastic elongation than nylon fiber, easy to bond with rubber, and good heat resistance. Strength decreases by 10—25% when wet; used mainly in 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.

Supplementary Information
Ordinary conveyor belts are divided into many specifications and models according to different usage environments and requirements:
-
1
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).
-
2
According to different usage environments: heat-resistant, cold-resistant, acid & alkali resistant, oil-resistant, and food conveyor belts. The minimum thickness of the upper covering adhesive on ordinary and food conveyor belts is 3.0mm (lower: 1.5mm); for heat-resistant, cold-resistant, acid/alkali-resistant, and oil-resistant types, the minimum upper covering adhesive thickness is 4.5mm (lower: 2.0mm). Depending on the specific usage environment, the thickness of upper and lower covering adhesives can be increased by 1.5mm.

Frequently Asked Questions
Q
What raw materials are used to manufacture general conveyor belts?
General conveyor belts are refined from all cotton canvas (CC) or nylon (NN) / polyester (EP) fabrics through processes including rolling, forming, and vulcanization. The core can be woven from cotton, nylon, polyester, or vinylon fibers, either individually or in blended/interwoven combinations.
Q
What bandwidth and layer options are available for general conveyor belts?
General conveyor belts are available in bandwidths ranging from 300mm to 3000mm and can be manufactured with 1 to 12 fabric layers, allowing them to suit a wide range of load capacities and application requirements.
Q
What temperature range can new material general conveyor belts withstand?
New material general conveyor belts are engineered to operate continuously across a temperature range of -73°C to +260°C, making them suitable for both extremely cold and high-heat industrial environments without compromising dimensional stability or performance.
Q
What are the standard performance requirements for the conveyor belt covering layer?
According to execution standard GB/T7984-2001, the covering layer must meet the following: tensile strength ≥ 15 MPa, tensile length at break ≥ 350%, wear amount ≤ 200 mm³, average interlayer bonding strength ≥ 3.2 N/mm (between layers), and interlayer bonding strength between covering adhesive and layers ≥ 2.1 N/mm.
Q
What types of specialty conveyor belts are available based on usage environment?
Based on different usage environments, conveyor belts are available in a variety of specialty types including: heat-resistant, cold-resistant, acid & alkali resistant, oil-resistant, food-grade, flame retardant, anti-skid, climbing, corrosion-resistant, moisture-proof, and more — each designed to meet specific industrial demands.
Q
What is the difference in minimum cover adhesive thickness between standard and specialty conveyor belts?
For ordinary conveyor belts and food conveyor belts, the minimum upper covering adhesive thickness is 3.0mm and the lower covering adhesive is 1.5mm. For specialty types such as heat-resistant, cold-resistant, acid/alkali-resistant, and oil-resistant belts, the minimum upper covering adhesive thickness increases to 4.5mm and the lower to 2.0mm. Thicknesses can be further increased by 1.5mm depending on the specific environment.
