Two guide bar warp knitted fabrics are used as technical textile applications nowadays. In this, Part III of these series of papers, models for basic two guide bar warp knitted fabrics are created and given based on Parts I and II. Modeling of warp knitted fabrics started in the 1960s with some basic geometrical models and it was continued with using Non Uniform Basis Spline (NURBS) curves and surfaces. There were discontinuities in the loop parts in early created geometrical models and the NURBS models needed some control points from some sources. In this work instead of using NURBS curves, modeling of warp knitted fabric is attempted by using known curves. During creation of the models, curvature equalities are attained as much as possible, loop connection parts are modeled by having two continuously connected parabolas for the Double Tricot fabric and the loop connection parts of the other two bar fabrics are obtained by applying a sinus square curve to the connection part of the Double Tricot fabric. The models created are versatile and they can be changed and used for special cases. Models created are drawn to scale by using the 3DS-Max Computer Graphical Program. At first glance, it is seen that the model shapes are similar to the real fabric structures, which can be observed on photographs of them.
