The subject of the paper is the analysis of the dynamic thread stretching process under extreme
conditions of the excitation speed with the physical phenomena described in terms of rheological
models. The analysis was carried out using three basic models relating to viscoelastic bodies,
i.e. the Maxwell, Kelvin-Voigt and Standard 2 models. The relationships between the reaction forces of
the stretched threads and the input parameters of the process were included both in an analytical form
and in a numerical model. The theoretical analysis was related to the experimental tests carried out on
polyester threads with a linear mass of 84, 110 and 334 dtex, assuming the tensile speed ranging from
0.6 to 1.5 m / s. The experiment was carried out on a custom designed test stand.
In the conclusion of the obtained research, it can be stated that the most appropriate model
for the description of the analysed thread stretching process is the Standard model 2 and it should
be emphasized that the traditional analysis based on analytical relationships coincides with the results
of numerical analysis. This proves the correctness of the adopted numerical model with specific
boundary conditions.
