Description

technical field [0001] The invention belongs to the technical field of electrostatic spinning and textile machinery, and in particular relates to a tubular electrostatic spinning device and method. Background technique [0002] Electrospinning is one of the most effective ways to prepare nanofiber materials. Compared with the preparation techniques of nanomaterials such as stretching method, template synthesis method, and self-assembly, electrospinning has the advantages of simple operation, short preparation process, and wide selection of materials. advantage. Compared with traditional textile fiber materials, due to their extremely small scale, nanofibrous materials have many characteristics that are difficult to exhibit at large scales, such as obvious surface and interface effects, unique small size effects, large specific surface area and extremely large size. high porosity etc. Therefore, nanofiber materials have a wider range of applications, such as air filtration,...
