Study of the feasibility of a natural dye on cellulosic textile supports by red padouk (Pterocarpus soyauxii) and yellow movingui (Distemonanthus benthamianus) extracts

Alkaline and aqueous extractions of padouk and movingui sawdust were performed in this study with the aim of using to dye cotton fabric, wood viscose and bamboo viscose textiles. Coloration was carried out without a mordant. Colored materials were washed with soap and the extent of staining was measured fifteen days later using a Datacolor D65°10 apparatus. The parameters L*, a*, b* were measured to determine the depth of the color penetration after dyeing. A comparison of the different cellulosic supports showed that cotton presents generally a better ability to dyeing than bamboo and wood viscose.
