Multi-nozzle static spinning device

Abstract

The application discloses a multi-nozzle static spinning device which comprises a plurality of spinning nozzles, a collecting device and high voltage power supplies, wherein a spinning solution flow passage is formed in each spinning nozzle in the axial direction; warm air flow passages are formed in the periphery of each spinning solution flow passage; the warm air flow passages are communicated with an air pump; a heating device is arranged between the air pump and the warm air flow passages. According to the invention, the warm air flow passages are formed in the periphery of each spinning solution flow passage, through the stretching function of the warm air flow passage, the diameter of the fiber can be further reduced, the unstability of the static spinning process can be improved, the landing direction of fibers can be guided, and the efficiency of the static spinning technology can be improved; through the utilization of the combined action of airflow stretching and electrostatic force stretching, the controllability and yield of nanofiber preparation can be improved, and the yield is improved by times to dozens of times as compared with the standard electrospinning technology.
