Problems solved by technology
[0003] However, the traditional electrospinning equipment cannot control the air humidity. Directly apply DC voltage on the nozzle, and the diameter of the spinneret is small. Once the voltage is high and the air humidity is high, it is easy to produce discharge phenomenon, leading to fire accidents. Equipment safety Worrying; in addition, the position of the nozzle of the electrospinning equipment in the prior art is fixed, and the fiber thread with fixed characteristics is obtained through the drum, and then the fiber thread needs to be treated twice to obtain the required fiber film, and the fiber cannot be processed as required. The characteristics of the silk thread are adjusted, and secondary treatment is required, and the efficiency is low

Description
technical field [0001] The invention relates to the technical field of nanofibers, in particular to a nanofiber electrostatic spinning device. Background technique [0002] Nanofiber is a wire-like material with a diameter of nanoscale and a relatively large length and diameter. It has many unique properties and has received more and more attention in the fields of information, biology, environment, and energy. Electrospinning is a way of using electrostatic atomization of polymer fluids to form micro jets of polymers, which are finally solidified into fibers. In recent years, the preparation of nanofiber materials by electrospinning technology has become one of the most important topics in the field of material science and technology in the world. [0003] However, the traditional electrospinning equipment cannot control the air humidity. Directly apply DC voltage on the nozzle, and the diameter of the spinneret needle is small. Once the voltage is high and the air humidit...
