The stability of weft threads in fabrics with variable density by weft is analyzed. It is shown that the threads at the boundary of dense and sparse sections shift toward the section with lower density. Two relative indicators are proposed for quantitative assessment of thread shift. Thread shift coefficient characterizing the shift of a single weft thread. The total shift coefficient allows to estimate the "blur" of the section boundary as a whole. The shift of weft threads at the section boundaries is estimated using the proposed indicators. Theoretical indicators are obtained based on calculated data on the shift of weft threads. Experimental values of the indicators are obtained by processing photo images of cotton fabric of four articles. It is shown that the deviation of the calculated indicators from the experimental ones does not exceed 5%, which allows using the proposed indicators in practice.
