Since 1856, the textile industry has used natural dyes, a form of cellulosic fibre that may be printed with a wide range of hues. Cellulose is a natural polymer consisting of long chains of AGUs (anhydrous-D-glucopyranose units). Benefits include high specific characteristics, low density, cheap cost, abundant availability, and renewable nature. Renewable and biodegradable indoor and outdoor dyes cannot fulfil the vast demands of the textile industry since most land is used for food and feed production. Several international initiatives have been launched to address the issue of colour flaws, and the use of certain synthetic hues on endangered species is prohibited by the Global Organic Textile Standard (GOTS). Natural dyes are now exclusively used to irradiate textiles by traditional craftspeople, hobbyists, and small businesses in the cottage industry. Dyeing cellulosic fibres with a mordant did not appreciably improve their colourfastness, but mordanted cotton fibres absorbed more dye under the same dyeing circumstances. Protein and cellulosic textile substrates may be dyed and finished with Acacia auriculiformis. Experiments have revealed that by adding damping to the cellulosic process, thermal stability and colour retention are enhanced after washing. More education is required to increase demand and consumption.
