In the production process of polypropylene fiber, polypropylene spinning oil plays a vital role. Polypropylene fiber is widely used in textile, industry and other fields due to its light weight, high strength and wear resistance. However, the lack of polar groups in its molecular structure leads to poor conductivity and strong hydrophobicity, which brings many challenges to spinning processing. Polypropylene yarn spinning oil is the key to solving these problems.

Polypropylene yarn spinning oil is mainly composed of smoothing agent, sizing agent, emulsifier, antistatic agent and other components. Smoothing agent can reduce the friction between fibers and fibers, fibers and metals, and ensure the uniformity and spinnability of fibers during spinning; sizing agent helps fibers to hold together, improves the sizing of fibers, and makes fibers less likely to scatter in subsequent processing; emulsifier can make the components of the oil evenly mixed to form a stable emulsion, which is convenient for uniform oiling; antistatic agent can effectively eliminate the static electricity generated during spinning, avoid mutual repulsion of fibers due to static electricity accumulation, and affect production efficiency and product quality.

In practical applications, the performance of Polypropylene yarn spinning oil directly affects the processing performance of polypropylene fiber and the quality of the final product. For example, in the high-speed spinning process, high-quality spinning oil can reduce problems such as oil scattering, ring-shaped hair, and broken ends, and improve the continuity and stability of spinning. At the same time, suitable spinning oil can also improve the dyeing performance and feel of the fiber, making the final product more competitive in the market.

With the continuous development of the polypropylene industry, the requirements for Polypropylene yarn spinning oil are getting higher and higher. Researchers are constantly exploring new formulas and preparation processes to improve the performance and environmental protection of spinning oils.
