Abstract:

In this article, we analyse the behaviour of woven and knitted fabrics while pulling a discshaped specimen through a round hole of an experimental stand. Some mathematical simulation models have been formed for this complicated process of textile deformation. The results of comparative investigations into six types of textile specimen are presented as a set of geometrical measurements made at different stages of the experiment. The analysis of computational and experimental results shows the sufficient precision of Cassini oval and shortened epicycloid curves for modelling the process. Conditions are identified for applying the method of pulling the textile specimen through the round hole for measuring the parameters of textile anisotropy, textile hand and other mechanical properties.
