Optical characterization of the state of fabric surfaces

Contribution of polarimetric imaging for the characterization of fibrous surface properties at different scales

“…This study follows a previous study realized by the authors, during which a nonimaging optical texturometer was developed [3]. It allows the user to detect periodical structure elements of textile surfaces through the study of the light reflected by the sample.…”

“…Tension, compression, friction, bending, shear are key parameters which are essential in the future use of the product and are commonly studied [1]. We already developed techniques to evaluate the surfaces properties of textile fabrics [2][3][4]. In this paper, we improve these techniques and develop new ones for nonwoven characterization by the use of polarimetric imaging.…”

“…The latter data extraction often proves rather simple and therefore less subject to noise than classic image processing techniques reported in [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. This approach can seem less flexible, since it requires the development of specific apparatus, but it allows us to extract information hardly visible in intensity images, which cannot be recovered by image post-processings [3,4,22]. Section 2 deals with a state of the art of nonwoven characterization, at both scales of interest.…”

Optoelectronic Techniques for Surface Characterization of Fabrics

“…Then structure and hairiness have to be separated. The optical assembly (Figure 4 and 5) proposed by Bueno et al (2000) includes a laser diode for the sake of compactness. In front of the fabric, the beam goes through a beam expander and then illuminates the fabric.…”
