The role played by the industrial warp knitted fabrics has become very important in recent years in industry, agriculture, medicine, etc. This matter is due to the superior properties of these fabrics, including their low weight, suitable elasticity, constant dimensions, high durability, stability at high and low temperatures, resistance to corrosion and degradation and their low costs. In the textile industry, problem faced by engineers is mostly because of complexity of the fibrous products in terms of geometrical and mechanical properties. The finite elements method is a numerical technique that can be utilized for various complexities in the field of engineering such as stress, heat transfer, electromagnetism, and fluid analysis. In the present research, mechanical properties of Marquisette and Laid-in warp knitted fabrics have been considered for their industrial and home applications, the mechanical software “ABAQUS” was used for modeling of various patterns in warp knitted fabrics and analyzing the results during vertical drape. After performing bending, drape and strength tests and evaluating the test results, the best possible patterns were presented for the appropriate applications. The results obtained from the bending test showed that, laid-in structure with three needle space has the best application in orthopedics. The result of the drape test also showed that two Marquisette structure desigened with four and three in-lay yarn, and with three and two in-lay yarn, has application in curtain net. The strength test results showed that the tensile strength of the laid-in fabric with four needle space is more than other fabrics. The results of mechanical analysis by using ABAQUS software presented that the Marquisette structure with four and three in-lay yarns has the most dimensional stability, least displacement and least element deformity in course of time than other patterns. Hence structural changes in Marquisette structure have great effect on the displacement of the elements.
