In this study, apple leaves were used to dye wool and cotton fabrics. Effects of mordant type and dyeing technique on color yield and fastness properties were investigated. The selected dyed fibre sample surfaces were observed using a scanning electron microscope (SEM). Color strength (K/S) values of the dyed fabricswere between 0.53 and 20.56. Washing and rubbing fastness results of the dyed fabrics were moderate/high. The SEM images of the naturally dyed fabrics demonstrated a smooth surface profile. We have concluded that apple leaf is suitable for the natural dyeing of wool fabrics.
