Nanofiber Composite Nonwoven Fabric
Nanofiber

Hirose Paper Manufacturing has developed a nanofiber production method using a nozzle-free electrospinning technique.

This innovative technology, combined with Hirose’s ultra-thin wet-laid paper production process, has led to the creation of the “Nanofiber Composite Nonwoven Fabric.”
By integrating a traditional wet-laid nonwoven layer with a nanofiber layer, we have significantly improved processability without compromising the unique advantages of nanofibers.

Features of the Nozzle-Free Electrospinning Method

Compared to conventional electrospinning techniques, our newly developed method offers the following advantages:

  • No clogging issues: Since no nozzles are used, fiber production is not hindered by clogging, ensuring consistent spinning speed.
  • Scalability: The spinning area can be easily expanded, enabling high-volume nanofiber production.
  • Uniform web formation: By modularizing the spinning elements, fiber production becomes more uniform, reducing basis weight fluctuations.
  • Direct composite fabrication: Nanofibers can be directly spun onto substrates such as nonwoven fabrics, making integration with existing materials simple and efficient.
