Embodiment 1
[0023] In this example, polyvinyl alcohol (PVA) nanofibers were prepared by a helical needle-free electrospinning method. The collector is selected as a conveyor belt collector with a perimeter of 1m, a width of 50cm, and a steel mesh material. The surface of this collector is provided with a layer of polypropylene (PP) spun-bonded non-woven fabric (gram weight 20g / m 2 ). Before the electrospinning process starts, the voltage of the collector is set to 0V, and the real-time voltage monitoring system, charge elimination system and servo control system are started at the same time.
[0024] Electrospinning was then carried out using an 8% PVA aqueous solution (average molecular weight 146,000 to 186,000, 96% hydrolyzed). The spinning parameters are: spinning voltage 60kV, spinning distance 15cm, spinning head rotation speed 5rpm, collector moving speed 1m / min. The environmental parameters are: temperature 25°C, humidity 40%.

Embodiment 2
[0030] The material of the collector in Example 1 is replaced by a steel mesh material with a copper mesh material, and other processes, parameters and steps are the same as in Example 1.
[0031] Using the spiral electrospinning equipment with the novel dynamic adjustment collecting device of this embodiment to carry out electrospinning, the phenomenon of flying filaments disappears during the electrospinning process, and the yield and quality of the prepared nanofiber membranes are significantly improved. As shown in Table 2, compared with the spiral electrospinning equipment with a common collector, under the same spinning parameters, the bonding fastness between the nanofibers prepared in this example and the base cloth increased, and the nanofibers The diameter uniformity of the nanofiber membrane and the uniformity of the nanofiber membrane are increased, and the yield of the nanofiber membrane is also significantly improved.

[0035] The PP spun-bonded non-woven fabric covered on the surface of the collector in Example 1 was replaced with aluminum foil, and other processes, parameters and steps were the same as in Example 1.
[0036] Using the spiral electrospinning equipment with the novel dynamic adjustment collecting device of this embodiment to carry out electrospinning, the phenomenon of flying filaments disappears during the electrospinning process, and the yield and quality of the prepared nanofiber membranes are significantly improved. As shown in Table 3, compared with the spiral electrospinning equipment with a common collector, under the same spinning parameters, the bonding fastness between the nanofibers prepared in this example and the base cloth increased, and the nanofibers The diameter uniformity of the nanofiber membrane and the uniformity of the nanofiber membrane are increased, and the yield of the nanofiber membrane is also significantly improved.
