The aim of this paper is to review the sustainability of natural dyes. Natural dyes are cheap, easily obtainable, decomposable and plenty in nature. These dyes are collected from nature and no need to apply manufacturing process to prepare them. These dyes are easily decomposed in nature after using and they do not pollute the environment while destroying them after end use. Clothing dyed with natural dyes provide excellent feel of nature that cannot be obtained after using synthetic dyes. Due to their excellent nontoxic and non-allergenic characteristics, people of all ages can use the clothing dyed with natural dyes. These dyes do not do any harm to the baby skin. They have wonderful capabilities to protect humane from ultra-violate radiation and extreme sun burning. Shades created by natural dyes are shooting to humane eye, comfortable and soft feel. They produce exceptional color ideas and these shades are normally harmonious. Extensive research can be carried out on green dyes to interchange toxic synthetic petroleum based dyes. It has been a matter of discussion that synthetic dyes give a superior glow and a range of colors where the natural dyes give only limited or dull colors shades. Natural dyes are components those provide the feel of superior sensual experience. This paper opens possible ways for the scholars to further study in this field.

There is a great importance of this paper in the textile wet processing zone since, dyeing of fabrics with natural dye is always exciting. Different scholars worked related to this paper at different times where literature review exposed different results. Some scholars reported that Natural dyes are prepared from numerous plant-based, mineral, and animal products, comprising vegetables, fruits, wood, bark, berries, lichen, roots, plants, grasses, nuts, and kernels as well as creatures, shellfish and nonliving complexes [1]. Considering the poisonous properties of the synthetic dyes, there has been a rehabilitated effort to learning and implementing the different natural dyes in the dyestuff industry. Chiefly, there are three groups of natural dyes. One group is obtained from vegetables, plants or trees like indigo [2].

Second group is obtained from animal sources titled Cochineal, and the balance group is obtained from mineral that is termed as Ocher. Natural dyes can offer the much needed substitute to the intricate world of chemical dyes [3]. The methods used to prepare these dyes comprise the application of a mordant, required chemical and auxiliaries [4]. A mordant is a substance used needed for the colors from the plants to connect with the fibers of the cloth [5].

Mordants are normally acids or metal salts like as copper sulfate. Some dyes are called as functional dyes, like cochineal, don’t requisite a mordant since they naturally cover one, typically tannin [6]. The fabrics those are needed to be colored are generally festered in a mordant solution before the dyeing procedure instigates [7]. The textile manufacturing industries are the second most contaminating industry in the ecosphere [8].

Synthetic dyes donate to a foremost part of this contamination, with approximately 20 percent of worldwide water pollution being related to the textile dyeing procedures [9]. The main funders to this problematic are the use of non-biodegradable petroleum-based dyes to dye textiles, the use of poisonous materials to fix colorants on the textiles, and the relief of great extents of these colorants and complex agents into the nearby environment [10]. Figure 1 shows the ecofriendly natural dyeing components obtained from fruits.
