The invention provides a clean electrospinning method, which comprises, on each drafting assembly of a ring spinning frame, drafting rove by the drafter of the ring spinning frame to output strands from a front roller, entering a twisting triangular zone, twisting, injecting spinning liquid into a capillary spinneret via a liquid flow controller, connecting the spinning liquid to a positive electrode of a high-voltage power source, connecting a polar plate to a negative electrode of the high-voltage power source, forming a high-voltage electric field between the capillary spinneret and the polar plate, stretching the spinning liquid extruded from the capillary spinneret into microscale or nanoscale fine filaments under the action of the high-voltage electric field, twisting the fine filaments with the strands together in the twisting triangular zone, winding on a yarn bobbin via a guide and a traveler, and making into yarn. The capillary spinneret and the liquid flow controller are arranged at the upper inclined side of the triangular zone, and the grounding polar plate is arranged under the triangular zone. The method provided by the invention can decrease hairiness of the yarn, improve strength of the yarn, and lower cost, and is suitable for fields of cotton spinning, flax spinning, wool spinning and silk spinning.
