“…Color Strength and Color Difference: Color strength (K/S) values of the samples were determined using the Kubelka-Munk formulation (Equation (1), where R: the decimal fraction of the reflectance of fabric, K: the absorption coefficient, S: the scattering coefficient), which was programmed in a Minolta 3600d Spectrophotometer (illuminant D65, 10 standard observers) based on reflectance measurements. The color difference in the treated sample compared to untreated fabric was evaluated using the L*, a* and b* coordinate values according to CIELAB; see Equation (2).…”

“…Textile dyeing processes consume excessive amounts of water and leave a large amount of untreatable hazardous waste, such as salts, hydroxides and unreacted dyes, in the environment. Environmental pollution associated with the textile industry is seen as a critical global problem and new technologies and alternative environmentally friendly processes need to be developed to alleviate this situation [1][2][3][4][5][6][7].…”

Large amounts of water, synthetic dyestuffs and chemicals are used in the wet processes of textile finishing, and at the end of these processes, liquors containing chemical substances create a waste load. For this reason, it is of great importance to develop new wet-finishing processes that use less water, dyestuffs and chemicals. For this purpose, the layer-by-layer deposition method (LbL) was used in this research as an environmentally friendly, sustainable method that can be used in wet-finishing processes to minimize chemical, water and energy consumption. The dyeing and functional finishing of cotton fabrics were carried out in one process by the LbL method. Cotton fabrics were pre-treated with a commercial cationic dye fixation agent and cationic charges were produced on the fabric surfaces. Reactive and direct dyestuff groups were used in the dyeing process of cotton fabrics and fluorocarbon was used in the functional finishing process. Eight and 12 dye/fluorocarbon layered structures were obtained by LbL deposition using a laboratory-type padder. Cotton fabrics were dyed and finished with the same dyes and fluorocarbon via the padding method and both samples were compared. The washing, rubbing and light color fastness properties, color strength and color difference of the dyed samples were tested. Tensile strength, air permeability, SEM graphs, contact angle, water and oil repellency analyses were performed for the treated fabrics.

“…Synthetic dyes are detrimental for health and have some hazardous impacts on the environment as well [2,3]. Natural dyes have emerged as an eco-friendly solution to the textile industries [4,5] due to their diverse shades on textile fibers [6] and fabric [7]. They can be extracted from natural resources like plants [8,9], herbs [10], fungi [11], lichens [1], minerals [12], insects [12] and different tissue cultures of animals [13,14].…”

Most of synthetic dyes are toxic for the environment. On the other hand, natural dyes are ecofriendly and can replace synthetic toxic dyes. In the present studies, a natural dye was extracted from rinsed and grinded olive peel in 1:10 ratio (m/V) with water. Then, fabrics (wool and silk) were dyed with the peel extract by using different types of dulling and shining mordants (FeSO 4 , CuSO 4 , CoSO 4 , SnCl 2 , K 2 SO 4 , Al 2 (SO 4 ) 3 , ZnSO 4 and NiSO 4 ). The mordants have shown best results for wool at the acidic pH (4-5) and for silk at the basic pH (8-9). After dyeing wool (at 70-80ºC) and silk (at 100ºC) with olive peel extract, by simultaneous mordanting method, an interesting variety of beige, buff and khaki shades were obtained. Color fastness was noted by matching the dyed fabric color with grey scale. The colors of dyed fabric were again noted after its washing, pressing by iron, rubbing and light exposure. The fastness results were found quite satisfactory. The investigated procedure of natural dye extraction is eco-friendly, safe for the environment and a safe technique as it does not involve any organic solvent. The natural dyes can be satisfactory potential substitutes of the synthetic environmentally hazardous dyes.

With the improvement of living standards, everybody is very much conscious about the environmental protection and health safety. Natural dyes have attracted more attention to the industry due to exhibiting better biodegradability and more compatibility with the environment. Characteristic colours that are gathered from common assets can be categorized as either plant, creature, mineral, or microbial colours and can be used for colouring a wide range of regular filaments. Late examination shows that it can likewise be utilized to colour a portion of the manufactured filaments too. Normal colours are not just utilized in the shading of material filaments, they are also utilized for food, prescriptions, handiwork articles, and leather preparing. Extraction and purification play a vital role in the processing of natural dyes. There are different types of extraction process currently available for these natural dyes, such as solvent extraction, aqueous extraction, enzymatic extraction and fermentation, extraction with microwave or ultrasonic energy, supercritical fluid extraction, and alkaline or acid extraction. All these extraction processes have their own advantages as well as some drawbacks depending on the parameters that need to be maintained during the extraction process. Appropriate extraction can be beneficial for specific types of such dyes. In this paper, the classification, characteristics, extraction methods, and the application of natural dyes are introduced in an organized manner.
