The objective of this study is to investigate the efficacy of leaf powder colorants as substitutes for traditional indigo
dyeing. Leaf powder colorants were prepared by hot air(50℃) and room temperature(25℃) drying methods from fresh leaves. The
presence of indigo in the leaf powder colorants was confirmed by UV/Visible absorption spectra. All the powder colorants showed
broad absorption at 602 nm as same as synthetic indigo. Dyeing was done by reduction method with sodium hydrosulfite and sodium
hydroxide. Leaf powder colorants produced blue color on silk fabrics, showing similar color to the one dyed traditionally with fresh
juice extract. The powder colorants prepared at room temperature drying were more stable for long term storage than that prepared
by hot air drying. Thus, the powder colorants prepared by room temperature drying was reduced and dyed in one-step process
without sodium hydroxide in the dyebath for further investigate dyeing properties. K/S value of the fabric dyed without sodium
hydroxide was much higher than one dyed with sodium hydroxide. Regardless of the addition of sodium hydroxide, rubbing fastness
was fairly good showing above 4 rating. Fastness to dry cleaning and light of the fabrics dyed without sodium hydroxide were more
higher than that dyed in alkaline condition. |
