Technology to find defects in the nanofiber web and measure its size and thickness real-time

 

Client / Market

• Nanofiber, fiber laminating, paper, film manufacturing site

 

Necessity of this Technology

• Defects in nanofiber web fabricated with electrospinning process has negative effects on nanofiber web’s penetration and filtration function.
• There is a need to test and analyze the nanofiber web’s defects to control the production process.

 

Technical Differentiation

• Defect detection method: Comparing the intensity of the concentrated light that pass through the defects in the opaque nanofiber web.
• Thickness measuring method: Observing the change in the average intensity of the concentrated light that pass through the opaque nanofiber web.

 

Excellence of Technology

• Concentrated light is illuminated as a line to minimize noise occurrence and can test the nanofiber web at a high speed.
• Concentrated light is illuminated as a line, and the contrast difference is great between the part with defect and the part without a defect that the location of the defect can be precisely measured.
• The location and number of defects can be measured in real time, and the thickness of the nanofiber web can be measured simultaneously.
