The invention relates to a preparing device of a high-effective continuous-type electro-spin nanometer
fiber felt, the invention comprises a
fluid supply system, a
metal roller, a receiving device and a
spinning fluid recycling groove. The process for preparing comprises firstly, preparing
polymer spinning fluid with correct concentration in a
dissolution kettle, temporarily storing in a
liquid storage tank after passing through a filter, secondly, connecting the
metal roller and the positive
electrode of a high-pressure
electrostatic generator, applying correct electrostatic pressure, leading an
aluminium screen cloth to connect ground, thirdly, leading the
metal roller to rotate in correct rotary speed, fourth, starting a measuring pump, feeding
spinning liquid from the
liquid storage tank to an even allotter, leading the spinning liquid to be evenly allocated to a spraying hole on the front end of the even allotter,
sputtering from the spraying hole to the surface of a rotating metal roller to form Taylor awl, fifthly, leading a coiling drum to rotate to drive a
fiber receiving net to move, and continuously receiving nanometer
fiber felt. The process for preparation of the nanometer fiber felt of the invention has high production efficiency, which is suitable for scale production of electro-spinning.
