Abstract
ABSTRACT Natural dyestuffs are innovative natural resources alternative to chemicals in the textile industry due to their antibacterial properties. The objective of this study was to reveal the color, fastness, and antibacterial efficiency of Rosa canina leaf extract in wool fabric dyeing. Aluminum potassium sulfate (KAl (SO4)2.12H2O), copper sulfate (CuSO4.5H2O), and iron sulfate (FeSO4.7H2O) metal salts were preferred in the pre-mordanting process. Two different natural dye concentrations (25% and 50%) were tested in mordant and non-mordant wool fabrics. The fastness values were ranked between medium and good grades with 2–6. One of the remarkable results was that the fastness values of the un-mordanted dyed samples were acceptable with 5. In disc diffusion analysis, ultrasonic water bath CH3OH extracts were found to be more effective against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 with 16.4 mm and 7.51 mm, respectively. Also, the dyed wool fabrics showed remarkable antimicrobial activity (reduction rates: w46e100) against two different bacteria according to AATCC 100 method.
