Problems solved by technology

Compared with electrospinning technology: solution jet spinning technology has high production efficiency, and its single-needle spinning speed can reach 10 times that of electrospinning speed, but the disadvantage is that when the solution is injected, it will be affected by air stretching and solution jet viscoelasticity. Bending occurs under the combined action, and whipping disturbance similar to helical motion occurs, resulting in uneven distribution of nano-spinning diameters

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a hand-held electrostatic and solution jet hybrid spinning device. Background technique [0002] At present, the spinning methods of electrospinning devices mainly include single-needle spinning, multi-needle spinning and needle-free spinning. Single-needle spinning is spinning through one needle. The main factors affecting the spinning result are: the inner diameter of the spinning needle outlet, the distance between the spinning needle and the receiving plate, the spinning voltage, and the type and concentration of the solution. As a nanofiber manufacturing technology, the fibers prepared by electrospinning process have the advantages of small diameter and uniform size distribution, but at the same time, the spinning efficiency is low and the equipment volume is large, which limits the development of electrospinning technology. [0003] Solution jet spinning is mainly to tran...
