Sažetak
Under conditions of use, form and properties of fabrics are constantly changing. Tensile forces cause the appearance of viscoelastic or plastic deformations. Such deformations are undesirable because they reduce the quality of the fabric. During fabric use, deformations should be within the elastic range. In order to avoid plastic deformation in fabric, it should be known in advance at what tensile load such deformations will occur. Depending on the mechanical properties of the fabric, an appropriate rheological model should be fitted that describes well their behavior in action of tensile load. For the purpose of testing the rheological properties of fabrics, raw cotton fabrics in sateen weave were weaved with the same warp density and different weft densities. Based on the experimental results obtained for elongation fabric samples, a rheological model according to Lethersich was set up that describes well the process of elongation cotton fabric and can be used to predict the boundary loads of cotton fabrics after which irreversible deformations occur. Appropriate differential equations for tested fabric samples were solved, resulting in dependence between tensile force and elongation.
