Device for preparing electrospun nanofiber yarns by using rotary collector and preparation method thereof

Abstract

The application relates to a device for preparing electrospun nanofiber yarns by using a rotary collector. The device comprises a high-voltage power supply (1), a negative solution tank (2), a negative spinning head (3), a positive solution tank (4), a collection transmission device (7), a hollow collector (6), a winding transmission device (9) and a winding device (8), wherein the negative electrode and positive electrode of the high-voltage power supply (1) are respectively connected with a negative spinning head (3) of the negative solution tank (2) and a positive spinning head of the positive solution tank (4). The device has the advantages that spinning liquid is provided for the negative spinning head (3) and a positive spinning head (5) from the negative solution tank (2) and the positive solution tank (4); under the action of high voltage, the spinning liquid is transformed into a nano fiber by a fiber generator, an upward fiber cone is formed above the hollow collector (6), the nano fiber yarns are pulled out of the vertex of the fiber cone and are twisted, wound and collected by rotation of the hollow collector (6), and finally are collected into continuous nano fiber yarns by the winding device (8). The nano fiber yarns have strong mechanical strength and can be used for producing various nano-fiber textiles.

Description

technical field [0001] The invention relates to an electrospinning nanofiber yarn forming device and method, in particular to a device and method capable of continuously preparing and twisting electrospinning nanofiber yarns, and belongs to the field of electrospinning devices. Background technique [0002] Nanofibers have gained enormous popularity in the last decade. They can be prepared by several techniques such as stretching, template synthesis, centrifugal spinning, self-assembly, and phase separation and electrospinning. Electrospinning to prepare nanofibers has attracted special attention because of its diversity, flexibility, and ease of forming uniform webs. Electrostatic nanofibers have enormous potential in various fields including filtration, biomedicine, controlled drug release, catalysis, sensors, protective clothing, energy storage and generation, and more. [0003] Electrostatic nanofibers are usually collected in the form of fibrous nonwovens with low str...
