The utility of polypropylene oil is not limited to the spinning process, but also shines in the production process of stretching and texturing.

The use of imported polypropylene filament oil agent can basically meet the requirements of production processes such as spinning, drawing and texturing. However, due to foreign exchange settlement, high prices, and transportation difficulties, it has been basically replaced by domestic polypropylene oil. The use of domestically produced oil agents, to varying degrees, there is a problem that the winding bobbin is not well formed, the tow gloss is poor, the yellowing is poor, the cohesion is poor, the tow is diverged, there is a collapse phenomenon when the doffing is dropped, and the hair is easy to appear when drawing.

However, with the development of domestic technology, the above defects have been improved, and the stability of the polypropylene oil has been greatly improved.
