This paper aims to develop the methodology for the imitation of exploitation conditions of textile products as well as to determine the exploitation peculiarities of high‐performance fabrics for outdoor clothing producible in Lithuania.
Static‐ and dynamic‐cyclic loading was applied for the imitation of exploitation conditions as well as for the investigation of the changes in specimen geometrical parameters.
The differences in the parameters of textile material stability determined under dry and wet cyclic specimen deformation were determined. The investigation results presented show that the parameters of air permeability can be used for the determination of changes in textile product shapes due to their cyclic washing as well as to the other kinds of wet technological treatment, especially in these cases when the small areas of product material are deformed.
The problems concerned with the methodology for the evaluation of exploitation stability of high‐performance fabrics (woven and knitted) for outdoor clothing are analyzed in this research.
In most cases, the exploitation behaviour of textile materials is investigated under uniaxial or static biaxial deformation. For better imitation of real exploitation conditions of textiles the new testing methodology based on two testing methods was established (original device for punch deformation working in creep mode as well as using wet and dry specimens; device ARRV for cyclic fatigue).
