Patent ID: 8827672

Claim:
An electrospinning device for fabricating a membrane by using spinnerets aligned in machine direction (MD) and transverse direction (TD) comprising a section for electrospinning nanofiber membrane, an ancillary section and a control section for controlling the operation of both the section for electrospinning nanofiber membrane and the ancillary section, characterized in that the section for electrospinning nanofiber membrane comprises a stainless steel conveyor belt, at least one MD spinnerets set mounted above the stainless conveyor belt with the spinnerets aligning in the MD, and at least one TD spinnerets set mounted above the stainless conveyor belt with the spinnerets aligning in the TD, the MD and TD spinnerets sets moving in a to-and-fro scanning manner transverse to the moving direction of the stainless steel conveyor belt, the electrospinning direction of the MD and TD spinnerets sets being perpendicular to a surface of the stainless steel conveyor belt, and a high voltage electrostatic field being applied between the MD and TD spinnerets sets and the stainless steel conveyor belt.
