Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spinning processing, in particular to an electrostatic spinning processing device capable of continuous solution polymerization. Background Art

[0002] Spinning is a process for making fibers, which mainly involves ejecting a polymer solution or melt through one or more fine nozzles and solidifying it into continuous fibers by mechanical stretching or other external forces. This process is widely used in the production of synthetic fibers, such as nylon, polyester and other synthetic materials. Traditional spinning techniques, such as melt spinning and wet spinning, usually involve heating the polymer material above its melting point and then stretching it by mechanical force, or dissolving the polymer in a solvent and then extruding it through a nozzle and solidifying it in a coagulation bath.

[0003] These traditional processing methods have some limitations and disadvantages. For example, high temperatures during melt spinning may cause certain polymers to decompose, limiting the types of materials that can be used. Wet spinning involves complex solvent recovery and treatment systems, which has a heavy environmental burden. In addition, these methods are usually difficult to control the microstructure and surface properties of the fibers, limiting the functionality of the fibers in high-end applications (such as biomedicine and nanotechnology).
