Definitions
- the present invention relates to a printed material sorting method and a paper making method using the printed material.
- ADVANTAGE OF THE INVENTION According to this invention, it is possible to select the used paper suitable for papermaking of a recycled paper from printed matter, and can produce the recycled paper of the outstanding quality from printed matter.
- Non-Patent Document 1 Non-Patent Document 1
- Patent Document 1 proposes a method for identifying bills and the like using a Fourier transform near-infrared analyzer (FTNIR).
- FNIR Fourier transform near-infrared analyzer
- this method is for discriminating securities such as banknotes, and is a technique that can be applied only to clean printed matter with little contamination and wrinkles because the optical fiber probe is closely attached to the printed matter and the spectrum is measured. It has been difficult to apply to printed materials that are complicated and severely damaged, such as used paper raw materials.
- Patent Document 2 proposes a method for selecting a printed material that is difficult to recycle as used paper based on the solubility of the printed surface of the printed material in a solvent.
