Problems solved by technology

These spinning methods all adopt the traditional single-needle electrospinning system, which has the limitations of low output, small fineness and unstable spinning process.
In addition, these methods cannot achieve the stable motion of the jet during spinning and cannot achieve the directional cohesion of nanofibers.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to an electrospinning nanofiber yarn forming device and method, in particular to a multi-strand air-jet friction yarn forming device and method capable of large-scale and continuous preparation of electrospinning nanofiber yarns. Background technique [0002] Electrospinning is a simple and effective method to prepare nanofibers. The basic principle of traditional electrospinning is that in a strong electric field, the polymer solution droplets form a "Taylor cone" at the spinneret. When the electrostatic field force exceeds the droplet surface tension threshold, the solution droplets are elongated and thinned. A charged jet is formed, and a randomly oriented nanofiber mat is formed through solvent volatilization and solidification. Due to its ultra-fine size, high surface area and porosity, electrospun nanofibers have shown broad application prospects in many fields such as clothing, biomedi...
