Tire Cord & Reinforcement Yarn

-- Steady & Reliable Manufacturer --

What Is Tire Cord & Reinforcement Yarn

Tire cord and reinforcement yarn is a high-tenacity, low-shrinkage industrial yarn, most commonly made from polyester (PET) or nylon (PA66/PA6), engineered to be twisted, plied, and woven or dipped into cord fabric that reinforces rubber products. Inside a tire, this cord fabric sits in the carcass and belt layers, giving the tire its structural strength, shape retention, and resistance to repeated flexing at high speed and load.

Beyond tires, the same category of high-tenacity industrial yarn is used to reinforce other rubber and composite products, including conveyor belts, hoses, and various molded rubber goods, wherever a rubber matrix needs an internal fiber skeleton to carry load.

Polyester vs Nylon for Tire Cord

Polyester tire cord offers good dimensional stability and lower cost, and is widely used in passenger car radial tire body plies. Nylon tire cord offers higher fatigue resistance and better performance at elevated temperatures, making it a common choice for truck, bus, and off-road tire applications, as well as certain belt and cap ply constructions.

Built for Downstream Dipping and Twisting

Because tire cord fabric is later processed through resorcinol-formaldehyde-latex (RFL) dipping and calendering to bond with rubber, GC FIBER controls the yarn's shrinkage, tenacity, and finish uniformity closely, so it performs predictably through your dipping and rubber-bonding process.

Application

Tire cord and reinforcement yarn is the fiber backbone behind a range of rubber-reinforced industrial products:

  • Passenger and light truck tires: body ply and cap ply reinforcement in radial tire construction.
  • Truck, bus, and off-road tires: higher fatigue-resistance nylon cord used in carcass and belt layers under heavier load.
  • Conveyor belts: internal fabric reinforcement layers giving belts their tensile strength and dimensional stability.
  • Rubber hoses: braided or spiral reinforcement yarn inside hydraulic, industrial, and agricultural hose products.
  • Molded rubber goods: reinforcement fabric or cord embedded in various technical rubber components.

Advantage

  • High tenacity for structural reinforcement: yarn is spun and drawn to deliver the strength needed to reinforce rubber under continuous flex and load.
  • Low, controlled shrinkage: shrinkage is managed closely so cord fabric dimensions stay stable through calendering and rubber vulcanization.
  • Dipping-process compatibility: yarn finish is controlled to work reliably with standard RFL dipping systems for good rubber-to-fiber adhesion.
  • Material matched to duty cycle: polyester for cost-efficient passenger tire applications, nylon for higher fatigue resistance in heavy-duty and high-temperature uses.
  • Manufacturer-level quality control: as the producer, we can hold tight tolerances on denier, tenacity, and shrinkage across large production volumes.

Payment Terms

We accept T/T (30% deposit, balance before shipment or against copy of B/L), L/C at sight for bulk container orders, and Western Union / PayPal for sample orders. Prices are quoted in USD by default, with project-based pricing available for large-volume industrial buyers.

Shipping & Delivery

Standard terms are FOB Shanghai / Ningbo, with CIF and DDP available on request. Samples ship by express courier within 3-5 working days. Bulk production lead time is typically 20-30 days after deposit and specification confirmation, shipped by sea freight (FCL/LCL); we can also help plan phased delivery for ongoing production contracts.

  • Q: Should we choose polyester or nylon cord for our tire construction?
  • A: Polyester is generally more cost-effective and stable for passenger tire body plies, while nylon offers better fatigue resistance and heat performance, which is why it's more common in truck, bus, and off-road tires.
  • Q: Is the yarn ready for RFL dipping as supplied?
  • A: Yes, the finish and oil content are controlled specifically for compatibility with standard RFL dipping systems, though we recommend confirming your dipping formula and line parameters with our technical team for the best adhesion results.
  • Q: Can you supply pre-twisted cord yarn instead of single-end yarn?
  • A: Yes, we can supply either raw single-end yarn or twisted/plied cord yarn with a specified twist direction and turns per meter, depending on what your production process requires.
  • Q: What shrinkage level should we expect?
  • A: Low-shrinkage grades are typically at or below 8% dry heat shrinkage, but exact figures depend on the specific denier and process conditions, so we can confirm test data for your selected specification.
  • Q: What is the minimum order quantity for tire cord yarn?
  • A: Standard MOQ is 1,000 kg per specification; for ongoing industrial supply contracts, we recommend discussing your annual volume directly with our sales team for the best terms.
