NW-101

NW-101
Nonwovens Electrospinner

The model NW-101 is an electrospinning system to spin nanofiber nonwovens of high uniformity at high speed.
Nanofibers of which diameter is from 10nanometer to several micrometer can be spun with materials such as PVDF.

  • Development of innovative pipe spinnerets
  • Newly-developed pipe spinnerets with 30 or 60 jet outlets increased productivities 360 times at a maximum compared to existing systems with one syringe. (patent pending)
  • High speed spinning of 600mm-wide membranes
  • 600mm-wide membranes can be spun at 10,000mm per minute with the state-of-the-art technology.
  • Individual control of 3 high voltage supplies
  • The NW-101 can integrate 3 positive power supplies and 1 negative supply which can be controlled individually, enabling spinning with 3 different solutions at the same time.
  • High performance collector to convey very thin materials
  • Only 0.2mm-thick steel belt collector was introduced to carry thin base materials without being peeled.
    The conveyor speed can be programmed in the range from 20 to 10,000mm per minute.
  • Spinning thick and uniform nanofiber sheets
  • By applying negative high voltage at a maximum of 10kV to the collector nonwovens of more than 10μm-thick can be obtained. (patented)
  • Quick and easy programming of spinning conditions
  • Parameters to spin nanofiber sheets can be easily programmed with a 10-key controller. (See the table below.)
