ASSESSMENT OF Sorghum bicolor Leaves and Hibiscus sabdarifa CALYCES AS DYE ON COTTON FABRICS FOR WEALTH CREATION IN POST-COVID-19 PERIOD

Abstract

The study assessed the extraction and application of dyes from Sorghum bicolor leaves and Hibiscus sabdarifa calyces on cotton fabrics as a means of wealth creation during covid_19 period. It examined extracted dyes from the two plants, the composition, the color properties, and acceptability of consumers on these plant dyes for wealth creation. The study adopted research and development design. The composition were determined by High Performance Liquid Chromatography. Colorimeter was used to determine the L*a*b* colour properties. Acceptability of Treated Fabric Evaluation with a rating scale of 1-5 and 3 was decision rule. Two coded samples treated with the dye extracts were assessed by sixty respondents. Frequency, mean, and standard deviation were used to analyze the data. The HPLC analysis of the extracts showed that anthocyanin is the major colour bearing compound in Sorghum bicolor leaves and Hibiscus sabdarifa calyces. The colour properties identified showed that sample HYS is brighter with the value 54.82 than sample SXB with 54.07. The redness to greenness shows that the samples are reddish however, SXB is more reddish with a* value of 14.50 than HYS with a value 11.43. HYS is more bluish with b* value-19.21 while sample SXB has a value of -6.39. It was revealed that the two samples were acceptable in terms of overall acceptability: HYS is more acceptable with a value of 4.74 and SXB is 3.57. It was concluded that Sorghum bicolor and Hibiscus sabdarifa are good sources of natural plant dyes as they are rich in colour yielding compounds. It was recommended that the awareness of its utilization for households and commercial dyeing should be publicized as means of wealth creation.
