Polyamide 6 (PA6), a versatile and robust synthetic polymer, is the backbone of numerous industrial applications. From high-strength tire cords and automotive airbags to durable ropes, nets, and technical textiles, PA6 industrial yarn is prized for its exceptional tensile strength, abrasion resistance, and elasticity. However, the manufacturing process, particularly high-speed spinning, presents significant challenges. The immense friction and heat generated can lead to filament breakage, static buildup, and inconsistencies in yarn quality. Addressing these issues is paramount for efficient and high-quality production. This is where the application of a specialized spin finish, or spinning oil, becomes indispensable.

At NINGBO INNO PHARMCHEM CO.,LTD., we have developed a state-of-the-art Textile Auxiliary Spinning Oil specifically formulated for the high-speed spinning of PA6 industrial yarn. This product is engineered to overcome the inherent difficulties of the production process, ensuring a seamless workflow from the spinneret to the final wound package. Our spinning oil is a meticulously balanced composition of natural lubricants, nonionic and anionic surfactants, and powerful antistatic agents, designed to deliver unparalleled performance.

Exceptional Lubricity and Fiber Cohesion
One of the primary functions of our spinning oil is to provide superior lubrication. During high-speed spinning, where yarn can travel at several thousand meters per minute, friction is a major adversary. It occurs between individual filaments, between the yarn and machine guides, and on rollers. Excessive friction leads to increased tension, filament damage, and frequent breaks, causing costly production downtime. Our formulation creates a consistent, low-friction film on each filament. This not only protects the yarn's integrity but also ensures it glides smoothly through the machinery. Furthermore, the oil imparts excellent fiber cohesion, bundling the filaments together into a uniform yarn. This cohesion is critical for preventing stray filaments and ensuring a well-formed, stable yarn package, which is crucial for success in subsequent downstream processes like twisting, weaving, or knitting.

Superior Antistatic and Thermal Properties
Static electricity is another significant challenge in synthetic fiber production. The rapid movement and friction generate static charges on the yarn, causing filaments to repel each other, leading to a phenomenon known as 'ballooning'. This disrupts yarn control, causes entanglement, and results in poor package winding. Our PA6 spinning oil contains highly effective antistatic agents that safely dissipate these charges as they form. This ensures the yarn remains manageable, leading to higher processing speeds and superior yarn quality.

Moreover, high-speed spinning generates considerable heat. A spin finish must be able to withstand these high temperatures without breaking down, smoking, or creating harmful deposits (coking) on machinery like godets and hot pins. Our product boasts excellent heat resistance with a high flash point of over 260°C. This thermal stability ensures a clean, safe, and efficient operating environment, minimizing the need for machine cleaning and reducing the risk of defects caused by coke particles transferring to the yarn.

Technical Excellence and Environmental Responsibility
Our commitment to quality is reflected in the product's technical specifications. This light yellow, transparent oily liquid is composed of over 98% active ingredients, ensuring maximum efficiency with minimal application. It is non-toxic, odorless, non-corrosive, and importantly, does not contain APEO (Alkylphenol ethoxylates), aligning with global environmental standards and regulations. Its excellent solubility in both water and organic solvents makes it easy to apply through standard oiling jets and simplifies any subsequent washing processes if required.

Key technical indicators include:

• Kinematic Viscosity (25°C): 100-160 mm²/s, optimized for application and filament coverage.
• pH (20% aqueous solution): A near-neutral range of 6.0±2.0, ensuring it is non-corrosive to machinery.
• Acid Value: Very low (<5.0 mgKOH/g), indicating high purity and stability.

Driving Performance in Demanding Applications
The quality of the spin finish directly impacts the performance of the final PA6 industrial yarn product. By using our advanced spinning oil, manufacturers can produce yarn with enhanced strength, uniformity, and processability. This translates to better performance in end-uses such as automotive safety components, industrial ropes and belts, and high-performance textiles where reliability is non-negotiable. The fiber treated with this product is adaptable to a wide variety of processing methods, providing flexibility and value to the entire production chain.
