Eco-Friendly Cotton Dyeing Using Turmeric, Henna, and Citric Acid
收藏资源简介:
Dyeing recipe data Dyeing is a basic procedure in the textile sector wherein it is used to provide color to fibers, yarns or fabrics to improve the aesthetic and functional characteristics of the material. Natural dyeing has recently attracted a lot of interest as a greener alternative to synthetic dyes that are usually linked to environmental contamination and health hazards. Natural dyes are acquired out of renewable resources, including plants, roots, leaf, bark, fruits, and minerals. They are non-toxic, biodegradable and usually harmless to the human skin and the environment. The natural dye process generally follows three steps, namely preparation of the fabrics, mordanting, and dyeing. To increase the affinity of the dye to the cloth and to increase the color fastness, mordants like lemon juice, alum, or vinegar are added. As an illustration, turmeric and henna are two popular natural dyes, which can be used to create unique colors with eco-friendly processes. The coloring substance, curcumin, in turmeric gives it a shocking yellow, and henna, in abundant quantities, a warm reddish-brown. The dyeing process in both cases includes controlled heating and constant stirring to provide homogenous color absorption, rinsing followed by shade drying to maintain the quality of colors in a dye. Natural dyeing is both less wasteful of chemicals and a way of preserving ancient artisanship and facilitating the sustainable development of textiles. With the trend in the fashion sector to a more environmentally responsible approach, natural dyes can provide the avenue towards both the design and the eco-friendly approach.
