Despite the vast variety of studies in the field of effect of different mordants on dyeing and fastness properties of woolwith natural dyes, there is no thorough investigation on the effect of metal mordants on tensile properties of wool. In thisstudy, five different metallic salts namely aluminum potassium sulfate, tin chloride, potassium dichromate, coppersulfate, and ferrous sulfate were applied on wool with concentrations ranging from 1 %owf to 20 %owf. The tenacity ofthe samples was measured and SPSS software was employed to investigate the effect of different concentrations ofvarious mordants on tensile strength of woolen yarn compared with raw sample. The results showed that aluminumpotassium sulfate and ferrous sulfate had no statistically significant effect on the tenacity of the yarns while tin chlorideshowed the highest inverse effect and lowered the yarn strength significantly. Aluminum potassium sulfate and ferroussulfate reduced the tenacity for maximum of 4.2 %owf and 4.4 %owf respectively while the tin chloride treated samplewas completely destroyed when applying higher than 5 %owf of the mordant.
