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.
