  2. O índice e a direcção de rigidez na quantificação da orientação das fibras no papel: comparação com o método óptico da difracção laser. As técnicas ultra-sónicas encontram-se amplamente divulgadas na indústria do papel para medição do índice de rigidez (TSI) das folhas de papel. Para a indústria do papel o valor deste índice é assumido como sendo igual à anisotropia de orientação das fibras, o que acontece só quando a folha de papel é seca sem estar sujeita a tensões internas ou elongações. De forma a medir unicamente a anisotropi. 2007. Pereira, Mário José Teixeira; Fiadeiro, Paulo Torrão. http://hdl.handle.net/10400.6/537.
  3. Diffusion of the Laser Radiation to Characterise the Paper Fibre Orientation and the Paper Sheet Formation. This work concerns the determination of fiber orientation in the paper sheet and possibly the mass density distribution. Both parameters strongly influence the quality of the paper for end uses in printing and converting. The measurement of such parameters is done using different approaches, most commonly indirectly from the determination of the paper's physical properties. The measurement and ana. 2005.

  4. 3-D Characterisation of Nonwoven Fabrics by means of an optical system. The characterisation of fabric structure by means of quantified parameters is essential for the control of the fabrication processes and the resulting properties of the nonwoven materials. Important parameters of the structure are the porosity, the mean pore size and the pore size distribution, the specific area of the texture, the fibres orientation the last one needing to be characterised in the. 2000.

  5. New method for the measurement of fibres orientation on the paper faces applied to the analysis of hygro-instability in paper sheets. For a given change in the humidity of a paper the hygro-instability of the sheet depends of two main factors: ¿ the sheet structural parameters which reflects its structure: the sheet porosity, the fibres orientation distribution mainly in the sheet plane and the variations of these parameters across the paper sheet thickness. ¿ the water reactivity of the components of the paper sheet which depen. 1999.

  6. Structure of papers and Nonwovens. We characterise the structure of fibrous materials: papers and nonwovens by diffraction and transmission of light. This allows the measurement of the fibres orientation distribution of the sample as a whole or for the surfaces using replicas. Applications of the methods are demonstrated in the case of paper for the control of the curl tendency and for two kinds of nonwoven materials, one used in t. 1999.
