Abstract

The invention provides an electrostatic spinning machine which comprises a spinning solution spray device, a fiber receiving device, an electric field generation device, a magnetic field generation device and a first rotation device, wherein the fiber receiving device is arranged at the lower part of the spinning solution spray device; the electric field generation device comprises two electrode plates which are arranged along the vertical direction and are distributed at two sides of a central axis between the spinning solution spray device and the fiber receiving device; the magnetic field generation device comprises two magnetic pole plates which are arranged along the vertical direction and are distributed at two sides of the central axis; the first rotation device is used for driving the magnetic pole plates to carry out rotary motion along the central axis. According to the electrostatic spinning machine, through addition of the magnetic field generation device and the first rotation device, the magnetic field direction continuously changes around the central axis, so that the anisotropy in the fiber in the spinning process is lowered; and the fiber thickness average rate and the fiber quality are improved.

Description

technical field [0001] The invention relates to the technical field of electrostatic spinning, in particular to an electrostatic spinning machine. Background technique [0002] Wool fiber is a natural high-quality textile fiber material. It not only has high thermal performance, but also has the advantages of moisture absorption, softness and complete color spectrum, and is deeply loved by consumers. However, every year in our country, a large amount of low-quality wool, waste wool, and leftover wool are discarded because they cannot be used, resulting in a large waste of resources. [0003] With the maturity of electrospinning technology in recent years, technicians are currently trying to prepare wool fibers by dissolving waste wool and extracting wool keratin for electrospinning. However, because the spatial structure of wool keratin is an α-helical structure, in the traditional electrospinning process, due to the large surface tension of the spinning solution, the aniso...
