dc.description.abstract | The preparation of dye powder from natural dyes is to study the preparation methods of
dye powder and comparison of color fastness. The natural dyes were used in this study containing
of Lac, Ebony heart wood, Sappan heart wood and Turmeric. were selected in this work to
prepare dye powder drying, salt adsorption and salt precipitation methods were selected in this
work. And dye powder was dyed on silk fabric. The result showed that the dye powder from
drying and salt precipitation methods showed higher K/S than salt adsorption method. The dye
powder of turmeric from drying method showed highest K/S. The dye powders of Lac, Ebony
heart wood, Sappan heart wood from salt precipitation method showed highest K/S. And the
washing fastness showed that the preparation methods were not significant. The dye powder of
Lac, Ebony heart wood, Sappan heart wood showed good light fastness and the dye powder from
Turmeric showed poor light fastness. | en_US |
