The method of mathematical modeling of viscoelastic properties of textile materials having a complex macrostructure is used for sewing threads and for variously twisted polyester yarn constituting them. The efficiency of the methods of determination of physicomechanical properties and of prediction of deformation processes relating to these materials is checked. The qualitative dependence of the effect of twist of threads and yarn on their physicomechanical properties and on the relaxation time spectrum is determined. The effect of twist on the elastic components of deformation and specific mechanical work of deformation is studied.
