Abstract

The invention discloses an electrostatic spinning device and a method for manufacturing hollow nanometer fiber and belongs to the field of a textile industry. The device comprises a high-voltage static generator electrically connected with a coaxial composite sprayer with two liquid inlets and one composite sprayer. A receiving electrode plate is connected with the ground. The coaxial composite sprayer is opposite to the grounded receiving electrode plate, and a certain gap is reserved between the coaxial composite sprayer and the receiving electrode plate. An automatic liquid supplying device is connected with all liquid inlets of the coaxial composite sprayer, a winding device is arranged between the coaxial composite sprayer and the receiving electrode plate, and base cloth or a fiber curtain conveyed on the winding device penetrates an area between the coaxial composite sprayer and the receiving electrode plate.

Description

technical field [0001] The invention relates to the field of textile industry, in particular to an electrostatic spinning device and a method for preparing nanofibers. Background technique [0002] Hollow nanofibers have broad application prospects in drug release, tissue scaffolding, catalysis, textiles and many other aspects. [0003] At present, the preparation of hollow nanofibers mainly includes self-assembly method and template method. The preparation of hollow nanofibers by the self-assembly method is obtained by self-assembly of carbon or boron nitride and polypeptides modified with surfactants or dispersed with surfactants in solution. Only some specific materials can prepare hollow nanofibers by self-assembly method. [0004] In the method for preparing hollow fibers by template method, one is to control the time of polymerization reaction in the nanoscale hole array on the surface of the template fiber to obtain a specific wall thickness or replicate the nanosca...
