Measurement of Textile Deformation by the Moiré Method

In this study, we discuss the applicability of the Moiré method for measuring the mechanical deformation of textile end-use products. The results can be summarized as follows: (1)The application of the Moiré method made it possible to describe the 2-dimensional deformation of the distance between adjacent loop centers and the skew angle of loops of knitted fabric at any point. The case of tensile stress on knitted cotton fabric was reported. (2)The Moiré method can thus be applied to detect the inhomogeneity ofloops and the skew angle, or the cover factor of knitted fabric. (3)The Moiré method will offer some suggestions for improving the production and construction of knitted fabric, when the measuring systemis improved to get higher precision and further 3-dimensional measuring is applied.
