Polypropylene yarn spinning oil: "lubricant" for polypropylene fiber processing

In the production process of polypropylene yarn, spinning oil plays a vital role. It is a key factor to ensure the smooth processing of polypropylene fiber and improve product quality. Polypropylene, that is, polypropylene fiber, has the advantages of light weight and high strength, but lacks polar groups in its molecular structure, has low hygroscopicity and poor conductivity. In the subsequent processing of spinning, it is easy to cause the yarn to slip and scatter, produce hair and waste yarn, etc. At this time, Polypropylene yarn spinning oil plays an important role.

Polypropylene yarn spinning oil is a special oil made by compounding a variety of auxiliaries and surfactants, which has multiple functions such as smoothing, bundling, and antistatic. During the spinning process, it can form a uniform oil film on the fiber surface, reduce the friction coefficient of the tow, enhance the spinnability of the fiber, improve the spinning efficiency, protect the fiber quality, and reduce the generation of broken ends and hair.

For polypropylene filaments, the spinning oil must have good wettability to ensure uniform oiling. During high-speed processing such as winding and stretching, the oil must be able to withstand the heat generated by friction, prevent the fibers from melting and bonding, and ensure the smooth progress of the processing. The spinning oil of polypropylene staple fibers pays more attention to the bundling, so that each fiber is evenly stressed and stretched.

In addition, the Polypropylene yarn spinning oil must also have good stability, be non-toxic, odorless, non-irritating to the skin and mucous membranes, and safe to use. At the same time, it should not corrode metals and protect processing equipment. With the improvement of environmental protection requirements, spinning oils are also constantly improving and developing in a more environmentally friendly and efficient direction.
