Abstract

The invention discloses a yarn spraying device and a spinning device for preparing nanofiber. The yarn spraying device comprises a spray pipe, a La Farr pipe-shaped inner hole is formed in the spray pipe, the throat portion of the La Farr pipe-shaped inner hole is communicated with a liquid inlet, one end of the La Farr pipe-shaped inner hole is provided with a yarn spraying opening, and the other end of the La Farr pipe-shaped inner hole is provided with an air inlet; a yarn spraying mesh is arranged at the yarn spraying opening; the mesh number of the yarn spraying mesh is about 300-500. Compared with the prior art, the spinning device has no requirements for the conductivity of a solution, and the range of the spinning solution is expanded. When the nanofiber is prepared, high voltage is not needed, and the instrument safety problems are solved; the yarn spraying device is arranged to be capable of being handheld, and therefore the operation is convenient and easy when spinning is performed.

Description

technical field [0001] The invention relates to a nanofiber preparation device, in particular to a nanofiber preparation device using high pressure. Background technique [0002] Today is the era of rapid development of nanotechnology and nanomaterials, and nanofibers are an important component of nanomaterials. Therefore, how to develop new technologies for preparing nanomaterials and create new products is the constant pursuit of researchers in nanofiber manufacturing technology. Target. Although there are many spinning methods that have great potential advantages in preparing nanofibers, there are still many problems. Electrospinning, as a method for preparing nanofiber materials that is simple and convenient for industrial production, has received widespread attention, but electrospinning also has its limitations and problems. There are mainly the following problems: [0003] First: Electrospinning requires a high voltage and certain requirements for the conductivity ...
