Description
Technical Field
[0001] The utility model relates to the field of spinning devices, in particular to a coaxial electrostatic spinning device for antibacterial polyester yarns. Background Art
[0002] Antibacterial polyester yarn is a synthetic fiber with antibacterial function, which is commonly used in textile manufacturing. This fiber can effectively inhibit the growth and reproduction of bacteria, thereby preventing the spread of bacteria and diseases. Electrospinning technology uses a high-voltage electric field to charge a polymer solution or melt. The charged polymer solution or melt overcomes the surface tension under the action of the electric field force to form a jet. During the jetting process, the solvent in the jet evaporates or the jet itself solidifies to form a fiber, which eventually falls on the receiving device.
[0003] When producing polyester yarn, the existing polyester yarn electrostatic spinning device needs to pour a charged polymer solution into a storage tank and then push the solution to make it spray out from the spinning needle. The solution is pulled up and cooled during the ejection process to form spinning. The stronger the driving force, the farther the solution is ejected and the finer the spinning. However, when the existing device pushes the solution to eject with the same pressure, the thickness of the spinning is related to the thickness of the textile needle hole through which the solution passes when ejected. Therefore, the existing device can only adjust the spinning thickness during the spinning production process by lengthening the solution injection distance. However, when the injection area is changed, the spinning will exceed the use range of the winding spinning device, thereby causing the spinning to fall and scatter. When producing spinning of different thicknesses within the receiving range of the receiving device, the spinning needle on the production device needs to be replaced with a needle with needle holes of different thicknesses, which makes the existing device inconvenient to adjust when producing spinning of different thicknesses.
