Annotation:

The new, universal and simple method for the evaluation of the behaviour of textile materials and their filar systems according to the complex behaviour of textile materials during exploitation was developed in this work. Developed new method is suitable for investigation and evaluation of textile materials and their systems deformations according to pecularities of wearing processes. In this work were defined optimal research conditions and suitable parameters of evaluation. Deformation properties are evaluated by graphical, digital and numerical methods. The new Y shape specimen method is close to real wearing conditions. The developed numerical research methodology of the Y shape specimen using the finite element method (FEM) provides and evaluates deformations of textile materials without the necessity to perform real experiments. Also, narrow limits of textile numerical research methods was extended.
