Rotary embedded electrostatic spinning device and spinning method

Abstract

The invention discloses a rotary embedded electrostatic spinning device and a spinning method. The rotary embedded electrostatic spinning device comprises an outer hollow cylinder spinning nozzle, aninner hollow cylinder, an injector used for injecting spinning liquid into the inner hollow cylinder, a numerical control micro-injection pump used for controlling the injector, a high-voltage positive electrode connected with the inner hollow cylinder and the like. The spinning method comprises the steps that the spinning solution is injected into the inner hollow cylinder, when the spinning solution rises and the liquid level is higher than an opening in the top of the inner hollow cylinder, a servo motor is started to drive the outer hollow cylinder spinning nozzle to rotate the high-voltage positive electrode is opened and connected, voltage is increased, a plurality of electrostatic spinning jet flows is generated above the opening, and an electrostatic spinning process is started; and the electrostatic spinning jet flows are received through a collecting device. The spinning solution can form liquid films in different states on the openings in different forms, and then the jet flows with different fineness are generated, so that a nanofiber film with four or more diameter distributions and distinct levels can be prepared in one step under the condition without using various spinning solutions and without adjusting spinning parameters.

Description

technical field [0001] The invention belongs to the technical field of electrostatic spinning and textile machinery, and in particular relates to a rotating and embedded electrostatic spinning device and method. Background technique [0002] Electrospinning is one of the most effective ways to prepare nanofiber materials. Compared with the preparation techniques of nanomaterials such as stretching method, template synthesis method, and self-assembly, electrospinning has the advantages of simple operation, short preparation process, and wide selection of materials. advantage. [0003] Compared with traditional textile fiber materials, nanofiber materials have many properties that are difficult to develop on a large scale due to their extremely small scale. [0004] The existing characteristics, such as obvious surface and interface effects, unique small size effect, large specific surface area and extremely high porosity, etc. Therefore, nanofiber materials have a wider ran...
