Diffraction Method of Measuring the Structural Characteristics of Fabrics Made of Chemical Fibres

The diffraction method allows simultaneously determining several geometric characteristics of fabrics of different weaves with a high degree of accuracy. The use of programs that elaborate diffractograms allows automating the measurements. The method significantly reduces the labor intensity of the measurements and can be used for moving fabrics of different weaves. The use of different photodetectors allows determining the length and width of the repeat, size of the through pores in the fabric, warp and weft thread diameter, linear filling over warp and weft, and surface filling. The method can be used to determine external defects provided in GOSTs: thread slippage, local warp and weft bulges, weave perturbations, fabric warping.
