Bu çalışmada, ipek kumaş doğal indigo bitkisi ile boyanmıştır. Sonra 20x20 cm2 boyutunda kesilmiştir. Bir kumaş hariç tüm kumaşlar aynı yüzdede şap (KAl(SO4)2.12H2O) çözeltisi ile mordanlanmıştır. Yeşil renk boyama için kumaşlar önce ayrı ayrı muhabbet çiçeği (Reseda luteola) ve mazı gomalağı (Quercus infectoria Olivier) ile daha sonra iki bitki beraber farklı yüzdelerde kullanılarak boyama yapılmıştır. Antimikrobiyel test 27 adet ipek kumaş için uygulanmıştır. Testler Staphylococcus aureus ATCC 6538 e karşı yapılmıştır. Sayım sonuçları koyu renkli kumaşlarda S.aureus’ un daha fazla azaldığını göstermiştir. Canlı mikroorganizma sayısı CFU/ml olarak koloni sayımı ile belirlenmiştir. Bakteri azalması tayin edilmiştir. Boyama yapılmış ipek kumaşlardaki renk bileşenleri ve onların yüzdeleri HPLC-PDA (yüksek performanslı sıvı kromatografisi) ile renk ölçümleri ise CIEL*a*b* spektorofotometresi yardımıyla belirlenmiştir

Anahtar kelimeler


Antimikrobiyal test, doğal boyama, Staphylococcus aureus, HPLC-PDA, renk ölçümü
