Dyeing of wool yarns with clove and investigation of antibacterial and ultraviolet protection properties

Nowadays dyeing of textiles with natural dyes has been considered according to environmental effects based on lower using of the synthetic dyes and chemical auxiliaries. In present research, the dyeing parameters including; type of mordant, concentration of mordant and concentration of clove have been investigated. The color strength (K/S) value and the color coordinates (L*, a*, b*, C*) of samples were obtained using calorimeter in CIELab color space. The results showed the dyed samples in presence of Cu and Al as mordant have higher lightness (L*) compare with dyed samples dyed with Fe. The ultraviolet protection results showed higher blocking effect of sample in presence of clove against photodegradation of methylene blue (MB) under sunlight irradiation. The antibacterial assessment of the dyed samples showed reduction of bacteria rate against S. aureus (95%). Also washing fastness assessment of the dyed samples showed the great durability of clove on wool in presence of mordant.
