Experimental and analytical analyses of the knitted fabric off-axes tensile test

Determination of mechanical properties and predicting the behavior of knitted fabrics during the manufacturing process and finally in the use is an important part of textile science. In this study the influence of knitted fabric anisotropy on the values of maximum force, corresponding extension and total work when axial tensile forces act on specimens cut at different angles with respect to the course direction of the knitted fabric were analyzed. A plain double weft knit fabric made of single cotton yarns was studied. For different angles of cutting samples, the curves of the relation between the values of the tensile forces and the extension at break were experimentally obtained. The mathematical models obtained were compared with the experimental results, and the corresponding correlation coefficients were calculated.
