The trailing arm two ends of the rotating nozzle mechanism of electric spinning equipment have nozzle, wherein can utilize No. 20 syringe needles as nozzle, and the preset height H of collecting electrode and received vector for example are 40 centimetres.Applying about 40 volts voltage behind discharge electrode, the WEB that the macromolecule filament forms on three-dimensional received vector.Compared to the three-dimensional received vector of inchoate WEB, its dioctyl phthalate (Dioctyl Phthalate; DOP) filter effect is 40 to 50 percentages.Yet after forming WEB on the three-dimensional received vector, its DOP filter effect is promoted to 85 to 88 percentages with electric spinning equipment of the present invention.
By the invention described above preferred embodiment as can be known, use the manufacture method that electric spinning equipment of the present invention carries out the macromolecule filament, its advantage is to utilize rotating nozzle mechanism to move with non-linear track, forms uniform WEB with any receiving angle so as to making the macromolecule filament on received vector.The skewness and the throughput rate that can overcome existing macromolecule filament like this wait problem slowly.
Though the present invention discloses as above with several preferred embodiments; yet it is not in order to limit the present invention; any person skilled in the art scholar without departing from the spirit and scope of the present invention; when the change that can do various equivalences and replacement, so protection scope of the present invention is when looking accompanying being as the criterion that the application's claim scope defined.
