Distinguishing Binding Agents in Fibrous Materials

High sensitivity across short and long wavelengths

For products mainly made of fibrous or similar materials, the aggregate state between fine products is maintained with an adhesive (a binder).
To maintain the aggregate state, it is necessary for adhesive to be applied uniformly and dispersed entirely in a tangling manner. However, because fibrous materials and adhesives are generally white or transparent, it is difficult to visualize their application condition with an optical microscope.

Using the All-in-One Fluorescence Microscope BZ-X800

  • Fluorescence observation enables visualization and quantification of the application condition.
  • As most adhesives are resin, they produce fluorescence when exposed to light (fluorescence) having only a specific wavelength range.
  • If different fluorescent wavelengths are produced by fibrous materials and adhesive, it is possible to distinguish them and visualize the application condition even if doing so is not possible with the human eye.
