Shear-type drafting electrospinning direct-spinning micron yarn device, method and application of conductive solution

Abstract

The invention provides a shear type draft electrostatic spinning direct-spinning micron yarn device of a conducting solution, a shear type draft electrostatic spinning direct-spinning micron yarn method of the conducting solution, and the application of the conducting solution. The device consists of a trumpet spray nozzle, a shear traction cone cylinder, a bundle collecting and winding mechanism, a liquid filling cavity used for storing the conducting solution, a negative high voltage source and a driving mechanism. The direct-spinning micron yarn method comprises the following steps that under the action of a high electric field, a trumpet edge of the conductive polymer solution extruded from a liquid filling cavity is umbrella-shaped, and after sprayed submicron filaments on a high-speed rotation cone cylinder are formed into nanometer filaments and are solidified under the shearing and drafting action, the nanometer filaments are gathered by a buncher and are twisted into micron yarns, and the micron yarns are wound into the yarns which can be directly woven or are woven after being twisted. The device is simple, effective and reasonable in structure, filament nanocrystallization, high-strength spinning filaments and twisted and converged yarns can be realized.

Description

technical field [0001] The invention relates to the fields of electrospinning, electrospinning and nanofiber spinning machinery, in particular to a spinning technology for electrospinning micron yarns directly. Background technique [0002] In recent years, with the development of nanotechnology, electrospinning technology has achieved rapid development. At present, most of the nanofibers obtained by electrospinning are in the submicron scale (100-1000nm), and there are few real nanofibers smaller than 100nm. How to shrink the submicron fiber to nanoscale fiber is a problem to be studied by scholars. [0003] Electrospun fibers are widely used in the fields of environment, energy, biomedicine, optoelectronics, etc. However, the currently studied electrospun nanofibers mainly appear in the form of films or felts directly stacked by fibers, which are two-dimensional disordered fiber aggregates. This hinders the expanded application of this material. Usually the yarn can be ...

Problems solved by technology

It is an indisputable fact that there is no drafting device in the electrospinning process, neither is it directly spun into a yarn, and the fiber fineness, low strength, large damage, many processes, and high energy consumption in the spun yarn

[0008] In summary, the existing electrospinning direct spinning yarns do not add KOCN electrolyte and generate shear drafting method to realize the direct synthesis of electrospinning draft thinning and achieve real nanometer size and single filament strength improvement.
