Polyester Dipped Yarn -The Reliable Backbone for HighPerformance Rubber Hoses

Introduction

In the global rubber hose industry, the performance of the hose is determined largely by the quality of its reinforcement material. Polyester dipped yarn plays a critical role as the backbone of rubber hoses, ensuring strength, durability, and stability.

At Suzhou Kingdom Textile Technology Co., Ltd., we have dedicated over 20 years to the research and production of polyester dipped yarn. Today, we are proud to be a trusted supplier for leading companies such as Dunlop, Sinopec, CNPC, Parker Hannifin, Gates Corporation, and Continental Group, among others.

Key Advantages of Our Polyester Dipped Yarn

1. ltra-Low Dry Heat Shrinkage

• Achieves 1% or below dry heat shrinkage, ensuring stable hose dimensions during production.

2. High Tensile Strength

• Provides outstanding breaking strength, allowing hoses to perform reliably under high pressure and extreme working conditions.

3. Excellent Dipping & Adhesion Performance

• Compatible with multiple rubber compounds, including:

  NBR (Nitrile Rubber)

  NR (Natural Rubber)

  CR (Chloroprene Rubber)

  EPDM (Ethylene Propylene Diene Monomer)

  TPU (Thermo

• plastic Polyurethane)

  Hypalon

• Ensures strong and lasting adhesion between the reinforcement layer and the rubber matrix.

Customer Success Story

A major European fluid handling group (such as Parker Hannifin or Continental) faced challenges in producing industrial hoses designed for high-temperature environments:

• Their existing reinforcement yarns exhibited a 3–4% shrinkage rate at 150°C, causing dimensional instability and a high rework rate.

After switching to our low-shrinkage polyester dipped yarn:

• Shrinkage stabilized at below 1%

• Hose qualification rate increased by 20%+

• Raw material waste and rework costs were significantly reduced

The client has since applied our product in their oil drilling and industrial hose series, and we have become one of their approved long-term suppliers.

Conclusion

In the competitive rubber hose market, reliability, durability, and consistency are the cornerstonesof success. At Kingdom Textile, we continue to deliver innovation and excellence, offering world-class reinforcement solutions for our global partners.
