| Abstract | <p><span style="font-family:sans-serif; font-size:16.6667px">The image processing of pictures from fi bres and fi brous materials facilitates the investigation of diverse ge-</span><span style="font-family:sans-serif; font-size:16.6667px">ometrical properties, such as yarn hairiness, fi bre bifurcations or fi bre lengths and diameters. Such irregular </span><span style="font-family:sans-serif; font-size:16.6667px">sample sets are naturally suitable to the statistical examination of images, using a random-walk algorithm. </span><span style="font-family:sans-serif; font-size:16.6667px">This results in the calculation of the so-called Hurst exponent, which is the asymptotic scaling exponent of </span><span style="font-family:sans-serif; font-size:16.6667px">the mean squared displacement of the walker’s position. Previous investigations have proven the appropri-</span><span style="font-family:sans-serif; font-size:16.6667px">ateness of this method for examinations of diff</span><span style="font-family:sans-serif; font-size:16.6667px"> erent fi bres, yarns and textile fabrics. In a recent study, we </span><span style="font-family:sans-serif; font-size:16.6667px">used AFM (atomic force microscopy) images, split into diff</span><span style="font-family:sans-serif; font-size:16.6667px"> erent greyscales, to analyse and quantify diff</span><span style="font-family:sans-serif; font-size:16.6667px"> er-</span><span style="font-family:sans-serif; font-size:16.6667px">ences between various nanofi bre mats created from polyacrylonitrile. In addition to the strong infl uence of </span><span style="font-family:sans-serif; font-size:16.6667px">the nanofi bre diameters, a certain impact of the AFM settings was also seen and must be taken into account </span><span style="font-family:sans-serif; font-size:16.6667px">in future research.</span></p> <p> </p> <p> </p> |
