Maya Blue, a pigment used by the Mayas in Yucatan, is remarkably stable: the color is not destroyed by hot concentrated mineral acids or by heating to about 250 degrees C. The principal constituent is the colorless mineral attapulgite. It is proposed that the pigment is an adsorption complex of attapulgite and natural indigo; a synthetic equivalent may be prepared from attapulgite and either in...

The aim of the study was to investigate dyeing conditions that are appropriate for sedge fi bers with natural indigo dye as they usually do not absorb water. conditioning is therefore essential in order improve their water and color absorption properties. process included soaking 1, 2, 3, 4, 5% sodium hydroxide (NaOH) ratio solution (a liquor ratio) 50:1 24 hours. conditioned were analysed func...

Indigo carmine dye is used in many industries like textile, paper, cosmetics, etc. It specially textile for dyeing denim. The untreated water discharged from these industries, especially the industry, poses a significant environmental threat. conventional physicochemical methods treating industrial effluent are very expensive and cause secondary pollution. In present study, an extracellular lac...
