With the technological progress and development of textile industry, traditional textile fiber materials cannot be unable to meet the basic requirements for the generation and processing of functional textiles. The research and development of ultrafine fiber have become one of the hotspots for textile fiber materials. Electrospinning technology is a convenient and effective way to prepare nanofibers, which has received extensive attentions from many researchers. However, the traditional single-needle electrospinning has the disadvantages of easy clogging and cleaning of needles, which seriously limit the large- scale generation and application of nanofibers. Based on this, the research progress of needleless electrospinning spinneret and spinning technology was systematically reviewed from the perspective of achieving the macromass preparation of electrospinning nanofibers. Firstly, the development history and basic principles of needleless electrostatic spinning technology were introduced. Secondly, the spinneret structure, spinning principle and spinning efficiency of existing needleless electrospinning spinnerets were summarized and analyzed. Finally, the current development status of nanofiber macromass preparation was reviewed. Meanwhile, the development direction and suggestions for the macromass preparation of nanofibers by needleless electrospinning technology were also put forward.
