STUDY ON COLOR STRENGTH OF COTTON FABRICS DYED WITH TECOMA STANS FLOWER EXTRACT

摘要

Natural dyeing of fabrics is preferred to be more ecofriendly compared with synthetic dyes since no harmful chemicals were involved in the dyeing process. In this study dye was extracted from the tecoma stans flowers by Soxhlet method using water as a solvent media. Multi level factorial design was used to select different combinations. Pretreated cotton fabrics were dyed with the above extract using three different mordants by varying its concentrations as per above design. The results showed that premordanting method with myrobalan and pomegranate gives good color strength compared with post and simultaneous mordanting methods.
