Abstract
The article presents the tensile forces caused knitted fabrics’ deformations non-uniformity analysis. At first, the tensile behaviour was analysed by applying new method based on specific Y-shaped and stretching specimen. This shape of specimen allows to fulfil wearing conditions of apparel made of knitted fabrics. After this, the article analyses research conditions and knitted fabrics’ deformability physical characteristics and determines longitudinal, transverse and angular deformations. The deformations properties were evaluated using graphic and numerical methods. Investigations have shown that elastane fibres significantly influenced fabric deformability, dimensional changes and deformations’ non-uniformity. Experiments have also shown that Y-shaped specimen tensile test is a simple, universal and reliable method suitable to obtain quantitative information about textile materials deformability.
