Problems solved by technology

However, so far, no continuous single nanofiber filaments have been produced, and the orientation degree of oriented nanofibers is not high, and the yield is relatively low.
Meanwhile, continuous individual nanofiber filaments and oriented nanofiber bundles have low strength and cannot be used in conventional weaving techniques

Embodiment Construction

[0028] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0029] A method for preparing oriented electrospun nanofiber yarns from a magnetic field, comprising the following steps:

[0030] (1) Nanofibers are produced continuously and stably through the spinning nozzle, and the nanofibers are sprayed into the insulating space. The nanofibers are in a movable and free state, and are in a disordered and random floating state without mechanical guidance during the yarn forming process. ....

Abstract

The invention relates to a method and a device for preparing oriented electrospun nanofiber yarns based on a self-magnetic field. The method includes stably producing nanofibers; driving the nanofibers to move directionally by spiral air flow; forming conical nanofiber bundles in spiral movement; bundling and performing fine drawing to obtain the oriented electrospun nanofiber yarns. The device comprises a spinning nozzle, a liquid supply device, an insulating cover, a round metal ring and a winding device, wherein the spinning nozzle is communicated with the liquid supply device through a guide tube and is disposed below the insulating cover and under the round metal ring, the insulating cover is in the shape of a cone with two ends open, the round metal ring is fixed to the lower half portion of an inner cavity of the insulating cover through metal rods, a plurality of air nozzles are evenly circumferentially distributed on the inner sidewall of the insulating cover and above the round metal ring, and the winding device is arranged above the insulating cover. The method and the device have the advantages that the nanofiber yarns can be produced continuously and stably, the nanofibers are orderly in height orientation arrangement in the yarns, and the oriented electrospun nanofiber yarns are obtained finally.

Description

technical field [0001] The invention belongs to the technical field of electrospinning nanofiber yarns, and in particular relates to a method and a device for preparing oriented electrospinning nanofiber yarns from a magnetic field. Background technique [0002] Electrospinning is currently the most popular technology for preparing nanofibers. Its products have excellent properties, such as a large specific surface area, flexible surface functionalization and excellent mechanical properties, etc., and can be applied to tissue Engineering, wound dressings, drug release, filter materials, composite reinforcements, sensors, etc. Since the electrospinning process is simple, the preparation process is shorter than conventional spinning, and the product has excellent functions, since Anton Formhals obtained the US patent in 1934, electrospinning has been concerned by fiber scientists and textile developers. This kind of nanofiber will become the leading product of our country in ...
