The automotive industry's relentless pursuit of safety, efficiency, and performance places immense demands on every component of a vehicle, right down to the fibers within the tires. Tire cord fabric is the critical reinforcement material that provides structural integrity, dimensional stability, and durability to tires, functioning as their very skeleton. Among the materials of choice for high-performance applications, nylon, particularly high-tenacity nylon industrial yarn, stands out for its exceptional strength, fatigue resistance, and toughness. However, the production of these advanced fibers is a complex process where every detail matters. Central to this process is the application of a specialized chemical agent known as spinning oil or spin finish.

NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of developing and supplying critical materials for this demanding sector. Our Spinning Oil for Tire Cord Fiber is a meticulously engineered product designed to meet and exceed the rigorous requirements of modern fiber manufacturing. This is not just a lubricant; it is a multi-functional processing aid that ensures the journey from molten polymer to high-strength filament is smooth, efficient, and results in a product of the highest quality.

The Critical Role of Spinning Oil in Fiber Production
In the melt spinning process, polymer is extruded through spinnerettes at high temperatures and drawn at incredible speeds to form continuous filaments. Without a proper spin finish, these nascent fibers would be impossible to process. The filaments would suffer from abrasion, breakage due to friction against machine guides, and uncontrollable static electricity buildup, leading to poor yarn quality and production stoppages. Our spinning oil addresses these challenges head-on, providing a suite of essential properties that are indispensable for manufacturing nylon cord and industrial yarn.

Chemical Composition and Performance Advantages
Our product is a sophisticated compound of a polyoxyethylene polyol polyfatty acid ester, a high-temperature resistant smoothing agent, and a high-molecular-weight polymer surfactant. This specific formulation delivers a synergistic combination of benefits:

1. Exceptional Heat Resistance: The spinning process for industrial yarns involves high temperatures. Our spinning oil exhibits an open-cup flash point of ≥220°C, ensuring it remains stable and effective without producing smoke or coking on heated machine parts like godets and plates. This thermal stability is crucial for maintaining a clean operating environment and preventing defects in the fiber.

2. Optimized Frictional Properties: A key challenge in fiber production is managing the balance between smoothness (low fiber-to-metal friction) and cohesion (adequate fiber-to-fiber friction). Our formulation provides superior smoothness to prevent filament damage and reduce tension, while also ensuring the filament bundle remains cohesive and uniform. This perfect balance is vital for achieving high tenacity and improving the overall strength of the final fiber, a non-negotiable requirement for tire cords.

3. Superior Antistatic Performance: Static electricity is a major disruptive force in high-speed spinning, causing filaments to repel each other ('ballooning') and cling to machine parts. Our spinning oil imparts excellent antistatic properties to the yarn, dissipating electrical charges as they form. This ensures controlled and orderly processing, which is essential for downstream applications like twisting and weaving.

4. Excellent Emulsifying and Detergent Properties: The oil is designed to be easily emulsified in water for application and, just as importantly, can be scoured from the fiber in later stages if required. Its detergent properties help in keeping the machinery clean, reducing downtime for maintenance. The 10% aqueous solution is stable for over 48 hours, providing consistency and reliability in production.

Technical Profile and Application Guidelines
This spinning oil presents as a tan, transparent liquid, signifying its purity and quality. It is formulated to achieve an oil content of 1.0-1.5% on the fiber when applied as a 15% emulsion, a level optimized for performance. Key technical indicators include:

• Viscosity (40°C): 130-190mm²/s, ensuring consistent and effective application via kiss-roll systems.
• pH Value (1% solution): 6.0-8.0, a neutral range that prevents any corrosion of the processing equipment.
• Content: 82%-85%, indicating a high concentration of active components.

Preparation is straightforward: the oil is added to industrial soft water under stirring to create a stable, uniform emulsion. It is non-toxic, odorless, non-corrosive, and non-flammable, making it safe for both workers and equipment. For storage, it should be kept in a cool, dry warehouse in its 200kg plastic drums, with a standard shelf life of one year.
