Sažetak
The article describes the application of elastic knitted fabrics in socks, sports and recreational clothes, swimsuits and various flat ribbons used in clothes production. A force/elongation diagram is described for uniaxial tensile load of the knitted fabric. Conditions prescribed by the standard for conducting cyclic loadings are provided. Measurements of cyclic loadings were conducted on four different types of knitted fabric: knitted fabrics of different density used in the production of fine women's stockings, knitted fabrics intended for recreational and sports clothes, swimsuits and elastic ribbons. Force drop and residual deformation were analysed in all the measurements. A special emphasis was placed on the analysis of the hysteresis curve index, which ranged from 0.000 to 0.920 in the conducted measurements. The index was the lowest in the highly porous knitted fabric of a fine women’s stocking lying on the leg under the crotch: usually 0.000 to 0.100. The hysteresis index in knitted fabrics designed for recreational clothes was 0.3 to 0.7, and in elastic ribbons used in clothes production 0.8 to 0.95. Further research is needed on the elasticity area of highly stretchable knitted fabrics.
