3K small tow carbon fiber product has upgraded. For 3K small tow production line, we did a comprehensive transformation, added a new electrolytic washing process, so that the product performance of small tow carbon fiber has been further improved. Carbon fiber, as a high-performance, lightweight and high-strength material, has been widely used in aviation, automobiles, ships, sports equipment and other fields.

However, during the production and treatment of carbon fiber, surface contaminants, chemical residues and microscopic defects often affect its performance and quality. In order to further improve the performance and quality of carbon fiber, we have carried out research and development of carbon fiber to increase the electrolytic washing process. Through the electrolytic washing process, contaminants and residues can be removed from the surface of carbon fiber, improving its surface purity and activity, so as to achieve better performance and application results.

The tensile strength of T700 grade carbon fiber is above 4.9GPA. Now this kind of product was a new research and development product of our company last year. The precursor adopts a unique wet two-step process. In the whole process of research and development, we tracked the whole process of carbonization stage production, and used data feedback to timely adjust the oxidation furnace, carbonization furnace temperature, drafting, waste discharge and other process parameters. To ensure that the quality and performance of the fiber meet the design requirements.

After 180 days of hard work, the research and development of T700 grade carbon fiber has been successful and has entered the mass production stage. This means that the process is stable and able to meet the needs of mass production to provide high performance carbon fiber materials for related industries.

35K carbon fiber product is unique to Jilin Chemical Fiber Group Co., Ltd., the world's first ace products. The 35K products are DNV-GL certified. This product is based on the carbon fiber production mechanism and strengthening process summary and data analysis through continuous learning of production experience. Then we developed this product through product design and technological innovation successfully.

The product is characterized by stable process, excellent quality, high yield and high production efficiency. It has the advantages of high tensile strength, high tensile modulus, less fluff, good yarn spreading, high flatness, easy to combine with resin and so on. The mechanical index is not lower than 25K, and it can reach the leading level of the same level of products in the industry. 35K products have better broadening advantages than 25K products, and have higher cost performance. Besides, this kind of product is mostly used in prepreg and pultrusion fields.

The 50K product has the largest width in our carbon fiber varieties. 50K carbon fiber is based on 35K carbon fiber, overcoming the problem that the wire connection of large tow carbon fiber is not good in the carbonization production process, and achieving continuous production. It has excellent yarn spreading performance, low fluff volume. Its mechanical properties is equal to 25K. Besides, its strength index is better than other manufacturers of the same specification products.

At present, it is mainly used in the field of prepreg. At present, it has continuous production and stable product supply capacity. Our group company is committed to the generalization and differentiation of large tow, the specialization and quality of small tow, and is committed to the production and research and development of carbon fiber to provide customers with satisfaction, rest assured and high-quality carbon fiber products.
