AB - An experimental and image analysis procedure were used to study the intra-ply shear behavior of 3-
dimensional weft knitted spacer fabrics. In this work, the picture frame fixture was designed to determine
its suitability for measuring intra-ply shear behavior of 3D spacer fabric. The nonlinear behavior of shear
force versus shear angle and the deformation mechanism were analyzed. The shear force versus shear
angle curves and wrinkles position of in-plane shear test are recorded by considering two different frame
lengths to compare with each other and load-displacement curves of inter-ply shear test are also analyzed.
In addition to this, the program was developed in matlab using Hough transform to analyze the shear
angle in the image taken during displacement of specimen at various positions. This image analyzed
results were compared with the actual experimental results. The findings of intra-ply shear behavior
spacer fabrics using image processing and experimental techniques are important for various functional
application. From the results obtained in this work, it is suggested that the picture frame fixture still
requires minor modifications to increase the accuracy of shear behavior of textile materials.
