Abstract:
Sorghum bicolor and Hibiscus sabdariffa are common plants whose uses have not been fully utilized. However, the two plants are rich in anthocyanins which make them a good dye substrate. Therefore, this study assessed the extraction and acceptability of dyestuffs from Sorghum bicolor leaves and Hibiscus sabdariffa calyxes. Organoleptic Attributes Acceptability of Treated Fabric Evaluation (OAATFE) was used to evaluate the 5 coded samples treated with the dye extracts and the composites developed, which were SXB1, HYS4, ABS6, ASH8 and ABH3. Questionnaire was used to gather information on the acceptability and utilization of the two dye extract by women in five communities randomly selected in Moro local government area. The result of the findings revealed that characterization of Sorghum bicolor leaves and Hibiscus sabdariffa calyxes shows that different anthocyanins are the major colour bearing compound. All the samples are acceptable with fabric dyed, with dye extracted from Hibiscus sabdariffa calyxes is more acceptable. Additionally, in terms of organoleptic acceptability, there exist significant differences between the samples with Hibiscus sabdariffa calyxes having the highest acceptability. Thus, the study concludes that Sorghum bicolor leaves and Hibiscus sabdariffa calyxes are good sources of natural dyes as they are rich in colour yielding compounds (anthocyanin). Hence, dye extracts from Sorghum bicolor leaves and Hibiscus sabdariffa calyxes can be applied in dyeing cotton fabric. However the study recommends the use of extract of 100% Hibiscus sabdariffa for women inMoro local government area as a means of poverty alleviation.
