If you have ever observed the spinning process in a chemical fiber factory workshop, you will surely be deeply impressed by the high-speed running filament bundle. But few people notice that in the process of Polypropylene (PP) melt being ejected from the spinneret and cooling to solidify into fibers, there is a key material that is indispensable like "blood" - it is Polypropylene yarn spinning oil. This seemingly ordinary liquid bottle directly determines the quality of the fiber, production efficiency and even the success or failure of downstream applications.

Why can't oil agents be used in the spinning process?

Polypropylene itself has excellent chemical stability, but the primary fibers formed after its melt spinning have obvious defects: dry surface, high friction coefficient, and severe static electricity accumulation. Without the protection of oil agents, high-speed wound fibers are prone to generating fuzz and broken ends, and subsequent processes cannot be carried out smoothly. The core function of Polypropylene yarn spinning oil is precisely to form an extremely thin and uniform oil film on the fiber surface through precise formula design, thereby endowing the fiber with key processing properties such as smoothness, antistatic property and bundling property.

What exactly is in Polypropylene yarn spinning oil?

High-quality Polypropylene yarn spinning oil is by no means a simple grease, but a precise system compounded from multiple functional components. Usually includes:

Lubricant: Reduces the friction between fibers and filament guides as well as rollers, minimizing wear and lint.

Antistatic agent: Eliminates static electricity generated by friction during the production process to prevent the dispersion and entanglement of filaments.

Bundling agent: It ensures an appropriate binding force between single filaments, guaranteeing the integrity and processability of the filament bundle.

Emulsifier: Ensures that the oil agent can form a stable emulsion in water, facilitating uniform oiling.

Adjuster: Fine-tune the hand feel and performance of the fibers according to the season, workshop temperature and humidity, and subsequent application requirements.

Therefore, the formula of chemical fiber oiling agents is highly customized and needs to be precisely matched with the spinning speed, fiber specifications (such as fine denier, coarse denier), and final uses (such as spunbond nonwoven fabrics, short fibers, BCF carpet filaments).

How do oil agents affect the value of the industrial chain?

A poorly compatible oil agent can lead to a high production breakage rate, significant equipment wear and tear, fluctuations in product quality, and directly increase costs. An excellent Polypropylene yarn spinning oil can ensure the high-speed and stable operation of production and endow the fibers with good post-processing adaptability, such as ensuring the uniformity of web laying in non-woven fabric production or the smooth passage of short fibers during carding and needling processes.
