Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber production equipment, and particularly relates to an adjustable device for oiling carbon fiber precursor. Background Art

[0002] The oiling step is crucial in the production of high-quality, high-performance carbon fiber precursor. A thorough and uniform oiling process can significantly enhance the hydrophilicity, bundling, and fiber separation properties of the precursor tow, significantly improving its performance.

[0003] To improve the efficiency of raw yarn production and enhance the performance of raw yarn tow, the raw yarn tow needs to be oiled more thoroughly and evenly. Some manufacturers resort to measures such as lengthening the oiling tank or reducing the spinning speed. This increases production and investment costs and affects production efficiency. At the same time, simply immersing the tow in oil will cause the oil to slowly penetrate from the surface to the interior of the tow, while the tow passes through the oil tank at a faster speed. This will cause the oil concentration on the raw yarn surface to be greater than the concentration inside the tow, significantly reducing the raw yarn performance. Utility Model Content
