Nnofiber spinning device

Abstract

The invention discloses a nanofiber spinning device, which comprises a material containing rotor, a rotating shaft, an upper heater, a lower heater and a collecting device, wherein a polymer is arranged in a material containing cavity in the material containing rotor, a nozzle communicating with the material containing cavity is formed in a side wall of the material containing rotor, the upper heater and the lower heater are respectively arranged at an upper side and a lower side of the material containing rotor, the bottom of the material containing rotor is connected with a top end of the rotating shaft, the collecting device is arranged around the external of the material containing rotor and the heaters, a material taking cavity is formed between the collecting device and an outer partition wall in a clamped mode, and the inner cavity of the nozzle is of a cone frustum structure. The design not only has no use for applying a high-voltage electric field, is independent of conductivity and higher in production efficiency, but also is better in collection effect, higher in yarn taking efficiency and wider in application range.

Description

technical field [0001] The invention relates to a nanofiber weaving device, in particular to a nanofiber weaving device, which is particularly suitable for avoiding the defects of high-voltage electric field and conductivity constraints, and improving production efficiency. Background technique [0002] Nanofibers refer to ultrafine fibers with a diameter of tens to hundreds of nanometers, which have unique advantages that other fibers cannot possess, such as very large specific surface area, ultrafine porosity, and good mechanical properties. In recent years, nanofibers have been widely used in textile materials, tissue engineering scaffolds, filter media, nanosensors, composite materials and other fields. [0003] The preparation of nanofibers has attracted the attention of experts and scholars at home and abroad. So far, there are many methods for preparing nanofibers, such as stretching method, microphase separation, template synthesis, self-assembly, electrospinning, e...
