The invention discloses an orientation electro-
spinning nanometer
fiber spinning method and a device thereof. A
metal shower nozzle which exerts positive and negative
high pressure is adopted to spin two strands of nanometer fibers with opposite charges, an
electric field line of a
spinning electric field, relative to a common spinning
electric field, is straight, stability of spinning is effectively restrained, and the spinning nanometer fibers are straight. Two strands of the fibers surround the
yarn tail and form a cone-shaped twisting trigonum on the upper portion of a
metal twisting
machine, and enable the nanometer fibers to be further oriented and twisted to form
yarn through electric field force,
tractive force of the
yarn and acting force of the
metal twisting force. The spinning nanometer
fiber yarn is conducted heat shaping through a
heat processing device under certain tensile force, degree of orientation of the nanometer fibers along the axial direction of the yarn,
breaking force and yarn levelness are further improved, and the yarn after shaped is collected by a winding
bobbin. The device can achieve the aim that orientation nanometer
fiber yarn can be continuously prepared, is simple in device, convenient to operate, and good in
resultant yarn continuity, yarn
breaking strength and yarn levelness, and not only can spin pure nanometer fiber yarn, but also can spin nanometer fibers / filament core composite yarn. The orientation nanometer
fiber spinning method and the device thereof have important application value in the fields, such as a biomedical field and a
sensor field.
