Multifunctional Cord Fabric: The Preferred Shared Material for Tire Frameworks and Conveyor Belt Core Layers

I. Core Applications: Fortifying Core Structures Across Two Scenarios (1) Tire Scenario: The Invisible Framework Safeguarding Safety

In tire frameworks, cord fabric forms the carcass by combining multiple layers of dipped cords with rubber, undertaking three core responsibilities: bearing the weight of vehicles and cargo to ensure structural integrity under heavy loads; resisting changes in temperature and air pressure to maintain tire dimensional stability; and dispersing impact forces from uneven road surfaces, enhancing wear resistance, and extending tire service life. The product caters to the differentiated needs of various vehicles such as passenger cars, heavy-duty trucks, construction machinery, and racing cars, and is a key material influencing tire performance and lifespan.

(2) Conveyor Belt Scenario: The Core Layer Ensuring Efficient Transportation

In conveyor belt core layers, cord fabric serves as a reinforcing material leveraging its core properties, with main functions including: withstanding the weight of materials and tensile stress during transportation to prevent fracture or permanent deformation; resisting friction and impact to improve conveyor belt durability; and maintaining dimensional stability to ensure smooth long-term operation. It is particularly suitable for heavy-duty conveyor belts in fields such as mining, ports, and chemical industry, adapting to high-load, long-distance, and complex operating conditions.

II. Material Types: Diverse Properties Adapting to Dual-Scenario Needs

The diverse material system of cord fabric accurately meets the differentiated requirements of both sectors:

• Nylon: Boasting outstanding high strength and wear resistance, it is suitable for heavy-duty tires and heavy-duty conveyor belts in mining, ports, and other fields.

  
  

• Polyester: Exhibiting excellent dimensional stability and resistance to deformation at high temperatures, it is an ideal choice for high-performance tires and long-term operating conveyor belts.

• Aramid: With a strength 5 times that of steel and lightweight properties, coupled with high modulus and high-temperature resistance, it is applicable to high-end scenarios such as racing tires and special-condition conveyor belts.

• Other Materials: Steel cord offers high strength and low rolling resistance, suitable for high-strength tires and heavy-duty conveyor belts; carbon fiber and PEN cords represent future upgrade directions for both sectors; cotton cords and viscose rayon cords are adapted for specific application scenarios.

III. Industry Trends: Multifunctional Upgrades Aligning with Dual-Sector Development

As the automotive industry transitions towards electrification, intelligence, and greenization, and the logistics and transportation industry moves towards efficiency, environmental protection, and heavy-load capacity, the cord fabric industry presents three major upgrade trends:

• Iteration of high-performance new materials: Expanded application of high-end materials such as aramid, carbon fiber, and PEN provides lightweight and high-strength solutions for both sectors.

• Green transformation: Development of eco-friendly raw materials such as bio-based and recycled polyester reduces the whole-life-cycle carbon footprint, responding to global environmental policies.

• Intelligent integration: Future integration of micro-sensor fibers is expected to enable real-time monitoring of the operating status of tires and conveyor belts, providing data support.

Conclusion

Breaking the limitation of single-scenario application, cord fabric has become a preferred high-performance cross-industry material with its dual-scenario adaptability as "tire framework + conveyor belt core layer". Its diverse material system, precision manufacturing processes, and technological upgrade trends align with the development needs of both industries. In the future, with innovations in new materials and processes, cord fabric will further break performance boundaries, continuously empowering tire and conveyor belt products, and supporting the high-quality development of both industries.
