“…Nowadays, the dyestuff industry is suffering from the increase in costs of feedstock and energy for dye synthesis and is also under increasing pressure to minimise the damage to the environment caused by the production and application processes used and the effluent produced. Natural dyes exhibit better biodegradability and generally have higher compatibility with the environment compared with their synthetic counterparts [19][20][21][22][23][24][25][26][27][28][29][30].…”

Cotton and wool fabrics were dyed with nine natural dyes obtained by aqueous extraction of the original plants/insect in an attempt to reconstruct traditional textile dyeing recipes, to optimise the methodology at all stages, i.e. extraction, mordanting and dyeing, and to standardise it. Cochineal, madder, alkanna, henna, brazilwood, red sandalwood, safflower, indigo and logwood were used for the dyeings, which were carried out directly and after mordanting of the textile material. A variety of mordants, namely, aluminium potassium sulphate, potassium dichromate, copper sulphate, zinc chloride, iron(iii) chloride, iron(ii) sulphate and tin chloride, is anticipated to meet both early and recent requirements and options. The dyeings were evaluated through colour measurements and standard wash, light and rub fastness tests. Generally, the mordanting process known for many centuries and connected with the textile dyeing resulted in an improvement in dye absorption and fastness properties mainly for the cotton samples, as is concluded from the tests and measurement assessments.

“…It is therefore being used to dye high-quality textiles manufactured with silk, cotton or wool (Takaoka et al, 1992;Tsatsaroni and Eleftheriadis, 1994;Liakopoulou-Kyriakides et al, 1998;Tsatsaroni et al, 1998). It is also used to dye rugs, hats and traditional clothes in Sardinia.…”

Saffron, with its intriguing history, is the world's most valuable spice and has a great reputation. Saffron spice consists of dried Crocus sativus L stigmas, used either whole, cut or ground. It is important to note that this plant cannot survive without human handling, which is why it does not grow in the wild. This chapter presents the origins, history, classifi cation, biology and morphology of saffron. Its chemical composition and dehydration procedures are described, together with its production and distribution, functional properties in relation to food, textiles, medicine (both traditional and modern) and others. Quality issues and applicable standards and specifi cations are described.

“…Enzymes have enjoyed considerable use for many years in the textile industry [5,6]: for example, amylases are used in desizing; cellulases are employed in denim finishing and the bio-polishing of cellulosic fibres; proteases are used in leather, silk and wool processing; and pectinases -amylase, lipase and diasterase -are used in the biopreparation of cotton fabrics. In our laboratory, we previously used enzymes for dyeing cotton with two natural dyes -namely, tectona and catechu -with very encouraging results [7,8].…”

The flowers of Delonix regia have been evaluated for the natural dyeing of silk using a biomordant and enzymes. This is an eco-friendly textile pretreatment that does not utilise metal mordanting. The aqueous extract obtained from the dried red flowers was used for the dyeing of silk fabrics. A bright reddishbrown hue colour was observed when 30% owf Delonix extract was used on the pretreated silk material. The silk fabric was treated with either an enzyme or biomordant. The resulting dyed fabric showed resistance to fading. Finally, all dyed specimens were tested for wash and light fastness properties, making Delonix a viable alternative to synthetic red dyes. Through desorption studies, the order of reactivity of enzymes towards dye uptake in the one-step process was found to be lipase > diasterase > protease-amylase = Pyrus (biomordant). For the two-step process, the order of reactivity of enzymes was found to be protease-amylase > lipase > Pyrus (biomordant) > diasterase. Overall, it can be concluded that, treatments, the two-step process was better in terms of larger colour yield values, fastness properties and both dye adherence ability.
