 Considering the importance of straight-line model in fabric cells to model their mechanical properties, straight-line models have been developed to fulfill the geometry of plain, rib 1×1, and interlock weft knitted fabrics in 2D and 3D states. To verify the generated models, these fabrics were produced in three densities. The loop lengths of the produced fabrics were precisely measured and compared with the loop lengths calculated by models. The results showed that the straight-line model is capable of predicting the loop length of these fabrics.
