Abstract: The objective of present study was to compare plain knitted fabrics comfort properties realized with hybrid and ring cotton folded yarns formed of two single yarns. The quality of the knitted fabric is determined by adiathermic power, air permeability and abrasion resistance. The results indicate that the plain knitted fabrics properties made of hybrid folded yarns are similar to those made of ring folded yarns. In addition to that, we notice that the yarn linear density and the folding twist factor have the most important effect on plain knitted fabrics properties realised with hybrid and ring folded yarns. This result is of a great industrial interest because the hybrid folded yarns costs less dearly than the ring folded yarns. In present study, Statistical models of the prediction are being presenting describing the variation of knitted fabric characteristics with the spinning and folding parameters and single yarns properties.
