On a textile market where the rules move to the restriction of some synthetic dyes, the industrialists become interested by natural ones which are considered to be harmless. In addition, they constitute a new source of income since they allow the creation of a new market and they aim a specific group of consumers. During last few decades, increasing attention has been paid to natural dye application as food colourant, in cosmetics and in textile coloration. This work aims the extraction of a concentrated dye from turmeric spice and its application for textile dyeing. The extraction method using Soxhlet extractor yields a highly concentrated dye. The various parameters that may affect the dyeing process were investigated. It was found that pH and temperature of dyeing influence considerably the results. Quality control of all dyeing was performed using standard fastness tests and colour measurements. The results were promising for turmeric concentrated extract as a natural dye. Thermodynamics of dyeing process were investigated
