The goal of the current study is to analyze the basic mechanical properties of the architec-tural fabric VALMEX, which is a composite material built of reinforcing polyester thread families and both sides PVC coated. The material was firstly subjected to biaxial loading of creep type for about 48 hours. The stress levels of the creep loading in two main or-thogonal directions of the fabric (commonly called the warp and fill directions) were in-troduced as follows: 4.6 kN/m, 10.4 kN/m, 16.4 kN/m, 22.4 kN/m, 28.4 kN/m, 34.4 kN/m. After creep loading the specimens were left unloaded for six months and then were subjected to the biaxial tension till rupture. For all the specimens the basic mechanical properties of the material were determined, for the warp and weft directions separately. The change of the obtained parameters shows the influence of biaxial prestress on the me-chanical performance of the VALMEX fabric.
