The objective of this study is to investigate the efficacy of leaf powder colorants as substitutes for traditional fresh
juice extract dyeing. Three kinds of leaf powder colorants were prepared by freeze drying method with or without deep freezing
as pre-treatment: one powder colorant from fresh leaf juice with deep freezing; two kinds of powder colorant from fresh leaves
with and without deep freezing. Their dyeing properties and storage stabilities were studied and compared with the traditional
fresh juice extract dyeing. The presence of indigo in the powder colorants was confirmed by UV/Visible absorption spectra. They
showed absorption peak at 602nm which was same with indigo absorption peak. Dyeing was done at low temperature around 6℃.
All three powder colorants produced B colors on silk fabrics, showing similar color to the one dyed traditionally with fresh juice
extract. The powder colorants from leaves gave higher color strength than the powder from leaf juice. The powder colorant
prepared from leaves with deep freezing was the most stable for long term storage as its color and color strength were not
changed after 360 days. So, this was used for further dyeing to study the effects of concentration and repeat dyeing on color
strength and colorfastness. Fastnesses to dry cleaning and rubbing were fairly good above 4 rating. Further study is needed to
improve light fastness. It was concluded that the leaf powder colorant with deep freezing could be used as a substitute for
traditional juice extract dyeing at all seasons. |
