A review of the characteristics and prospective applications of cola acuminata (cola nut) dye extract on textile materials.

The review explored the potential of cola acuminata (cola-nut) as a natural and eco-friendly dye source for textiles, taking into account its characteristics, and prospective applications on textile materials. Moreover, the review discusses the various techniques used to extract the dye from cola acuminata, the dye yield, the compound responsible for the color yield of the cola, its various applications, and prospect for sustainable management. There has been limited research on the sustainability of cola acuminata dye extract where there has also been a growing interest in the use of natural dye in the textile industry. Additionally, the production and use of synthetic dyes have been associated with several environmental issues, including water pollution, waste generation, carbon emissions, as well as health related problems for textile workers, particularly in developing countries. However, the dye extract of cola acuminata has been found to possess good color fastness properties and has proven to be a sustainable alternative to synthetic dye since it contains tannins, which are a type of polyphenolic compound that can be used as a natural dye. The tannins in the extract have been shown to have flavonoids properties, so that textiles dyed with the extract may be very resistant to microbial growth. Although, the tannin content of the seeds has been reported to be higher than that of some cola such as cola nitida, despite its lower dye yield. Moreso, the review emphasized on the importance of continued research in this field to optimize the dyeing process and contribute also to the enhancement of sustainable practice in the textile sector. It further provides valuable insights into the potential applications of cola acuminata dye extract particularly in the textile industry. [ABSTRACT FROM AUTHOR]
