Abstract:

A method is proposed for determining the skewness of the weft thread relative to the warp thread of textile fabrics, using the Fraunhofer diffraction pattern, which can be obtained either by an instrumental method on the appropriate apparatus or by a calculational method using digital microphotography of the sample by means of a two-dimensional Fourier-transformation program. The digital image of the diffraction pattern is analyzed by means of a special computer program that constructs an angular diagram of the intensity distribution of the diffraction maxima. The size of the angle of interest between the weft thread and the warp thread of the test sample is judged from the angle measured between the directions to the maxima in this diagram.
