Abstract

ABSTRACTA moderate approach was used to extract natural dye from wild Phytolaccaceae berries, and the stability and dyeing properties on the silk fabric of the exacted Phytolaccaceae natural dye was investigated. Via stability analysis, the natural dye had excellent stability during heating, pH or adding Metal ions. When the dyeing temperature was 30ºC, the K/S value of the dyed silk fabric was 6.3, and with SnCl2 mordant, the K/S value was increased 14.3%. The rubbing and washing fastness via metal mordant were increased by 0.5–1.5 grade compared to the fastness of fabric treated with direct dyeing method.
