Device and method for wrapping electrospinning nano-fiber with core yarn and then wrapping with filament to form yarn

Abstract

The invention relates to a device and a method for wrapping electrospinning nano-fiber with a core yarn and then wrapping with a filament to form a yarn. The device comprises a high-voltage power supply, a metal ring, a metal disk, a first driving motor, an insulating transmission rod, a spinning injection device, a core yarn unwinding bobbin, a first yarn guide mechanism, a second yarn guide mechanism, a hollow ingot silk winding machine and a winding machine; the high-voltage power supply is applied to the tip of a needle tube, the metal disk and the metal ring to generate an electric field,so that spinning liquid forms nano-fiber; the first driving motor is used for driving the metal disk to rotate, so that the nano-fiber is twisted and wrapped on the core yarn to form the nano-fiber covering yarn; and the hollow ingot silk winding machine is used for wrapping the fed nano-fiber covering yarn with silk to form a fascinated yarn, and the fascinated yarn is fed into the winding machine by the second yarn guide mechanism. The nano-fiber is sequentially arranged on the core yarn to form the nano-fiber covering yarn, and the nano-fiber covering yarn is wound with the yarn to form the fasciated yarn, so that the problem that the nano-fiber has low wear resistance is solved.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to a yarn forming device and method for electrospinning nanofiber core-spun yarns and wrapping filaments. Background technique [0002] Fiber and yarn have been the main materials in the traditional textile industry for thousands of years. With the existing textile processing technology, only fibers with a diameter of a few microns can be processed. Electrospinning technology can produce fibers with diameters ranging from a few nanometers to a few micrometers. However, the finer the diameter, down to the nanometer level, the relatively poor breaking strength and wear resistance of the fiber, making it difficult to process using traditional textile processing techniques. According to the specific needs of applications in the fields of textiles and clothing, microelectronic devices, and composite materials, if the application of nanoscale fibers is to be broadened, it is nece...
