Problems solved by technology

[0007] In view of this, the present invention provides an air bubble spinning device based on a magnetic field to assist in the preparation of ordered fiber materials. By setting a magnetic control device between the bubble injection tube and the receiving device, the jet flow can be realized in the process of forming fiber materials. The convergence in the longitudinal direction and the stretching in the transverse direction realize the controllability of the jet trajectory, so as to solve the technical problems that the jet angle is too large in the existing air bubble spinning process, and the unstable swing of the jet leads to disorderly collection of fibers , change the fiber microstructure and improve the orientation degree of the fiber

Embodiment Construction

[0033] In the process of air bubble spinning, the jet flow itself has the unsteady swing characteristic, which leads to the influence between the jet flows, and each jet flow is interlaced with each other, which leads to the randomness of the landing point of the fiber on the receiving device. The distribution of collected fibers is arbitrary, and it also brings certain difficulties to fiber collection. In the prior art, fiber materials are required to have good order in many fields, and electrospun nanofibers have good orientation. Therefore, the preparation of orderly and controllable nanofibers has become a research hotspot.

[0034] Aiming at the deficiencies in the prior art, the present invention provides an air bubble spinning device for preparing ordered fiber materials based on magnetic field assistance. By setting a magnetic control device between the bubble injection tube and the receiving device, the fiber material can be formed Realize the convergence of the jet i...

Abstract

The invention discloses an air bubble spinning device for preparing ordered fiber materials based on the assistance of a magnetic field. By setting a magnetic control device between a bubble injection tube and a receiving device, the longitudinal magnetic control device can realize jet flow when forming fiber materials. Convergence in the longitudinal direction, the transverse magnetic control device can realize the stretching of the jet in the transverse direction, and the controllability of the jet trajectory can be realized through the action of the magnetic field, so as to solve the problem of excessive jet angle and jet flow in the existing air bubble spinning process. The unsteady swing leads to the technical problem of chaotic and disordered fiber collection, changes the fiber microstructure, and improves the orientation degree of the fiber.

Description

technical field [0001] The invention belongs to the technical field of bubble spinning, and in particular relates to an airflow bubble spinning device for preparing ordered fiber materials based on the assistance of a magnetic field. Background technique [0002] Due to their very large specific surface area, excellent mechanical properties, unique bionic properties and significant size effect, micro / nanofiber materials have been widely used in biomedicine, energy security, composite templates and other fields. At present, the methods for preparing micro / nanofibrous materials mainly include template method, liquid phase reduction method, centrifugation method, electrospinning method, air bubble spinning method, etc. Strong whipping is unstable, so the prepared micro / nanofibers are mostly in the form of randomly arranged nonwovens. [0003] Air bubble spinning technology uses airflow as the driving force, and the bursting bubbles produce a large number of fine liquid columns...
