Abstract: Merino, Chokla and Rambouillet × Chokla single ply yarns of 8 Nm tex were dyed (at pH 2.5, 4.5 and 6.5) for 1h and 3h and boiled in distilled water for the same periods. The wet yarns were tested for stress-strain properties and the different parameters were analyzed statistically. The stress at 2, 15 and 30% extension and the hooken slope increased due to the treatments while the breaking stress and extension decreased. pH 25 treatment resulted in maximum lowering of stress values in Merino and crossbred yarns. pH 4.5 and pH 6.5 treatments resulted in better stress values. In general, Chokla yarn scored higher values.
