Carbonized carbon fiber filaments are woven into a fabric shape, forming a high carbon fiber cloth. During the weaving process, it is necessary to control the arrangement and density of fibers to ensure the performance of the final product. The woven high carbon silk fabric also needs post-processing, such as ultrasonic cleaning, heat treatment, stretching, and lubrication, to further enhance its mechanical properties and surface quality. Post processing techniques such as ultrasonic cleaning and heat treatment can further remove impurities and defects on the surface of fibers, improving their mechanical properties and surface quality.

The choice of spinning technology directly affects the performance of carbon fibers. Wet spinning, dry spinning, and dry spray wet spinning each have their own advantages and disadvantages, and the appropriate spinning method should be selected according to product specifications and performance requirements. Wet spinning is a traditional spinning method suitable for the production of large fiber bundles of carbon fibers. Dry jet wet spinning combines dry spinning and wet spinning to produce smaller carbon fiber bundles with better performance. During the spinning process, it is necessary to strictly control parameters such as spinning speed, temperature, and pressure to ensure the uniformity and quality of the fibers.
