With increasing environmental awareness, there is a growing interest in the textile industry towards bioactive extracts obtained from plants or plant waste as renewable and sustainable bio-resources. This interest is driven by the non-toxic, biodegradable and environmentally friendly nature of these extracts. Much research indicates that natural bioactive extracts provide various functions, including antibacterial and antioxidant properties, UV protection, flame retardants, and more. These results indicate promising opportunities for incorporating bioactive extracts into textile product development, especially in the field of medical and hygiene-related textiles. Furthermore, the use of natural functional dyes in textiles integrates dyeing and finishing procedures, representing an efficient technology characterized by minimal water and energy consumption. Moreover, natural finishing of textiles on an industrial scale is emerging as a tangible possibility in the eco-friendly textile market, paving the way for a greener and more sustainable textile industry. In this article, some plant extracts and wastes used in the dyeing and textile finishing were mentioned, such as: aloe vera, corn, orange, guava, banana, lemon, and peanut skin.
