Effect of pH on Natural Pigment Betacyanin Extraction from Bougainvillea Bracts

Abstract—Natural dyes derived from plant sources were used in textile industries. However, there are limitation involved with natural dye including laborious extraction of colour component of the raw material, low colour value and long dyeing time promote the cost of dyeing with natural dyes conside...
