This study examines the stretch properties of nine variants of single-tuck weft-knitted fabrics made from 31 tex ×2 wool/PAN yarn and compares them with a plain fabric. The research emphasizes how variations in the arrangement and percentage of tuck loops within the stitch repeat affect the fabrics' stretch characteristics. Results show that the presence and percentage of tuck loops at the width repeat significantly influence stretch properties. The plain fabric displayed apparent anisotropy, with widthwise deformation roughly four times greater than lengthwise deformation. This behaviour was largely dominated by the elastic component, indicating strong immediate recovery and dimensional stability. In contrast, tuck stitch variants showed more balanced deformation between directions, reflecting the moderating influence of tuck loops on fabric anisotropy. Increasing the percentage of tuck loops improved lengthwise extensibility while decreasing widthwise recovery, thereby altering elastic and residual deformation behaviour. The analysis of deformation components revealed that tuck loops decrease the elastic deformation ratio and increase delayed and residual deformation, suggesting greater stress relaxation and a higher permanent set. These results highlight the sensitive interplay between the presence and combination of knit and tuck loops and their effects on loop configuration and fabric mechanics. The results thus confirm that the controlled use of tuck stitches provides a practical approach to optimizing fabric performance in terms of stretch, recovery and stability, thereby offering valuable insights for designing functional and high-performance knitted textiles.
