Extraction of eco-friendly natural dyes from mango leaves and their application on silk fabric


The aim of the study was to evaluate the performance of dyes extracted from mango leaves in silk dyeing. Extraction medium was optimized by extracting dyes from fixed quantity of crushed leaves under pH values from 3 to 12. The maximum relative color strength of the extracted dye liquor was found to be at pH 10. The optimum dye extraction conditions i.e., the temperature, time, and material-to-liquor ratio were found to be 98 °C, 60 min, and 1:10, respectively. Dyeing was carried out with the optimized dye extract on mordanted and unmordanted silk fabrics. The dyed materials were evaluated by measuring the color yield and fastness properties. It was concluded that the color values were found to be influenced by the addition of mordants, consequently different fashion hues were obtained from the same dye extract using different mordants. It can also be said that mango leaves have good potentiality for dyeing of silk fabric.


Textile dyeing industry at present uses excessive amount of synthetic dyes to meet the required coloration of global consumption of textiles due to cheaper prices, wider ranges of bright shades, and considerably improved fastness properties in comparison to natural dyes (El-Nagar et al. 2005; Iqbal et al. 2008). But the production of synthetic dyes is dependent on petrochemical source, and some of these dyes contain carcinogenic amines (Hunger 2003). The application of such dyes causes serious health hazards and influences negatively the eco-balance of nature (Bruna and Maria 2013; Goodarzian and Ekrami 2010; Jothi 2008). Moreover, many countries already imposed stringent environment standards over these dyes. For instance, Germany has banned the azo dyes (Almahy et al. 2013). In this situation, a higher demand is put towards the greener alternatives or agricultural residues (Ammayappan et al. 2014). As a result, natural dyes are among the promising options for developing a greener textile dyeing process and such interest is reflected to the increased number of recent publications. Plant leaves are potential sources of natural dyes because of their easy availability and abundant nature.

Silk has been known as the “queen of fibers” since its discovery. Clothes made from silk are luxurious and have many excellent qualities including the material’s luster, light weight, superior mechanical performance, fine and smooth texture, excellent moisture transportation, and excellent draping quality (Cai et al. 2001). Mango bark has been reported to be used on silk and cotton materials as a source of natural dyes, and a wide range of colors have been produced using different mordants (Bains et al. 2003; Win and Swe 2008). On the other hand, the use of acid activated mango leaf powder (MLP) has been reported in another study for the removal of the Rhodamine B (RB) dye from aqueous solution (Khan et al. 2011). However, apart from this application of mango leaves, different leaves such as peach, poinsettia, acalypha, and parthenium leaves have also been reported to extract colors which were used in dyeing of silk materials (Mahajan et al. 2005; Rawat et al. 2006; Saravanan et al. 2013; Suneeta and Mahale 2002) while mango leaves have been reported to be used in batik painting technique on silk fabric in comparison with other four natural dyes (Klaichoi and Padungtos 2010). There is scope to extract color from mango leaves for the use in dyeing of silk fabric in order to get different fashion hues. The aim of the research was to evaluate the performance of dyes extracted from mango leaves in silk dyeing. The specific objectives were to analyze the aqueous extraction process of the dyes, to explore the possibilities of producing fashionable hues from the dyes using different mordants, to compare between unmordanted and mordanted dyed fabrics, to analyze the color values, and to assess the color fastness properties of dyed fabric.



Mango leaves used for the extraction purpose was collected from Roads & Highways Department, Dhaka, Bangladesh. Mangiferin as shown in Fig. 1 (1,3,6,7-tetrahydroxyxanthone-C-2-β-D-glucoside) was the chemical responsible (Luo et al. 2012) for providing color from mango leaves.

Chemical structure of mangiferin

Plain weave (1/1) raw silk fabric (22 g/m2 fabric) purchased from Sopura Silk Limited, Dhaka, was used for this study.


The leaves were washed thoroughly with water to remove dirt. They were dried under direct sunlight and grinded into very small units with the help of a grinding machine. The wastages are removed using a fine strainer, and finally, weight was taken. After drying, crushing, and removing wastages, the weight of 1 kilogram leaves was found to be 318 gram. Raw, dried, and crushed leaves are shown in Fig. 2.

The color component was extracted from the leaves in aqueous extraction process. Extraction was carried out with fixed quantity of crushed leaves (10 gram) under ten different pH values from pH 3 to 12 with a liquor ratio of 1:10 (Weight of crushed leaves in gram; amount of water in milliliter) at 98 °C for 60 min to optimize extraction medium. In each process of extraction, the mixture was cooled down and finally the dye extracts were filtered with fine filter paper three times to ensure clear dye solution.

The dye extracts obtained at different pH values were used for obtaining standard calibration curves through their absorbance values found using a dual beam reflectance spectrophotometer. The dilution of the extracts was carried out for the linear dependence on the concentration-absorbance relation at an absorbance peak (λ max). The absorbance values of extracted dye liquors under alkaline (pH 8–12) and acidic (pH 3–6) conditions were considered as batches, and relative color strength values of these batch solutions were measured from the spectrophotometer by comparing with the absorbance value of extracted dye liquor under neutral condition (pH 7) which was considered as standard.

Again, the dye extract which gave the maximum color strength was utilized to optimize the extraction levels of temperature, time, and material-to-liquor ratio. An orthogonal design of experiments was undertaken for this purpose.


Raw silk fabric was degummed in an aqueous solution containing soap (15 g/L), sequestering agent (1 g/L), and wetting agent (1 g/L) maintaining the bath at pH 9. The material-to-liquor ratio during the treatment was maintained at 1:50. The temperature was gradually raised to 80 °C and run for 60 min. The degummed fabric was washed with 2 g/L detergent at 65 °C for 10 min.


The degummed fabric was bleached by treating with 35 % hydrogen peroxide (3 mL/L), sequestering agent (1 g/L), wetting agent (1 g/L), and trisodium phosphate (2 g/L), maintaining a material-to-liquor ratio of 1:50 at pH 9 and temperature 60 °C for 60 min followed by washing with 2 g/L detergent at 65 °C for 10 min. CIE whiteness index of the bleached fabric was found to be 63.26.


Pre-mordanting was carried out on silk fabric using 5 % (on fabric weight) of ferrous sulfate, alum (potassium aluminum sulfate), and tin (stannous chloride) mordants individually and using four different combinations of mordants such as ferrous sulfate-alum (2.5 + 2.5 %), ferrous sulfate-alum-tin (2 + 2 + 1 %), alum-tin (2.5 + 2.5 %), and alum-tin-tannic acid (2 + 2 + 1 %) at 60 °C for 60 min keeping a material-to-liquor ratio of 1:30. Again, cream of tartar (CT) was used as a mordant assistant (Mortazavi et al. 2012) with stannous chloride, written as tin-CT.


Dyeing was carried out IR sample dyeing machine with the optimized dye extract as per standard parameters recommended for silk fabric, reported in Clariant manual, i.e., at 80 °C for 60 min under pH 5, keeping a material-to-liquor ratio of 1:50. Opticid PSD (1.5 g/L) was used as a buffering agent in the extracted dye liquor.

Color yield of dyed fabrics

Dyed samples were analyzed by measuring the reflectance curve between 350 and 750 nm with the spectrophotometer with illuminant D65 at 100 observer. The minimum of the curve (R min) was used to determine the ratio of light absorption (K) and scatter (S) via the Kubelka-Munk function (Mcdonald 1997).

$$ {\left(\frac{K}{S}\right)}_{\mathrm{Dyed}}=\frac{{\left(1-{R}_{\min}\right)}^2}{2{R}_{\min }}. $$

Color coordinates of dyed fabrics

The color coordinates of the dyed samples were determined based on the CIELab system via the spectrophotometer. In addition, ∆ECMC value was determined to show the color difference between mordanted and unmordanted samples.

Color fastness

Washing and light fastness tests were carried out in ISO 105 C02 and ISO 105 B02 method, respectively.

Results and discussion

Color strength of extracted dye liquors

Optimum pH was selected based on the relative color strength value of the extracted dye liquor at which maximum color was extracted. Changes in color strength were found due to changes in pH as shown in Table 1.

Table 1 Relative color strength of extracted dye liquors at pH 3 to12

It can be seen from the extraction results that the extracted solution showed maximum color strength at pH 10 which was 108.5. It was also found that from the neutral condition (pH 7), relative color strength values gradually decreased up to pH 4 and then increased at pH 3. The reason of extracting more coloring component in alkaline medium was due to the presence of acidic phenolic groups in mangiferin which reacted with alkali and formed more soluble salts in water as shown in Fig. 3. The solubility of the coloring component was increased due to the increased ionization of hydroxyl (phenoxide) groups in alkaline medium (Ali 2007).

Reaction of mangiferin with caustic soda

Again, increasing the pH from neutral condition improved the color strength of the extracted dye liquors up to a certain point. A further increase in alkaline pH resulted in decrease in the color strength of the extract. This decline in color strength was due to the high reactivity of mangiferin in concentrated alkaline medium (Spyroudis 2000).

Furthermore, the cell wall of leaves is composed of cellulosic material which gains anionic charge under alkaline medium. Because of these anionic repulsive forces among the cell walls, they lose their strength and ruptured easily (Ali 2007). In addition, as the observed leaf dyes have polyphenolic chromophoric structure, hence better extractions were observed using aqueous method (Sivakumar et al. 2009a, b).

Study of pH stability of dye extracts

It was noticeable during extraction that pH of the extraction bath changed gradually with time. Table 2 shows the pH variation after filtration and with time elapsed.

Table 2 Changes in pH at the extraction process

pH was found to be decreased in all the extraction baths from pH 3 to 12. This was due to the release of acidic color components from the leaves during extraction. From the neutral pH bath where the pH was set 7, the higher the alkalinity of the extraction bath, the greater was the pH drop rate. The drop rate became gradually slower while gradually approaching to more acidic bath from neutral bath. The pH was also measured after 24 h of the filtration process to notice the stability of the extracted bath at acidic pH, and no major noticeable change was reported.

Again, the dyes can show resonating form and give different tones with the change in pH because for natural dyes, pH changes very often. Furthermore, silk dyeing is recommended to be carried out in acidic medium as silk is sensitive to alkaline medium of dyeing, but extraction of the mangiferin dyes was optimized at alkaline pH. Therefore, the stability of the dyes after extraction is of importance.

Optimization of aqueous extraction conditions

The levels for each of the three factors in the orthogonal design of experiments are shown in Table 3. The extraction experiments were performed under optimum pH condition (pH = 10). The results of the orthogonal design of experiments are shown in Table 4.

Table 3 Factors and levels in orthogonal design of experiment for aqueous extraction
Table 4 The absorbance values and range analysis from orthogonal experiment

Optimum factors: A3B2C1,

Absorbance = 1.041.

The optimum extraction conditions were 98 °C for temperature factor, 60 min for time factor, and 1:10 for material-to-liquor ratio. It has been found that dye liquor extracted under optimum conditions had the maximum absorbance value, which was 1.041. From the range analysis of the average absorbance results as shown in Table 4, the most influential factor of extraction was material-to-liquor ratio, while extraction time factor was the least influential.

Dyed samples

The use of mordants and their combinations produced different shades on silk fabric which are shown in Table 5.

Table 5 Shades of dyed silk

Color measurements of dyed fabrics

The results of color measurements of the dyed silks are shown in Table 6.

Table 6 Color yield, color coordinates, and color difference of dyed fabrics

K/S value of the unmordanted dyed sample was found to be 11.85. This dye uptake on the silk fiber is attributed to the structural features of the fiber. However, in the mordanting method, mordant resulted in improved color yield of the dyed fabrics, except tin. Ferrous sulfate as a mordant significantly increased the color yield of silk. The K/S value was found to be 17.46 using ferrous sulfate which showed the maximum relative surface color strength value of 147.4 % considering the unmordanted dyed sample as reference. Besides, using alum with ferrous sulfate, and tin and alum with ferrous sulfate as a combination, color strengths were found to be 140.3 % (K/S = 16.62) and 121.7 % (K/S = 14.42), respectively.

In single mordanting process of silk, the order of color yield was found to be ferrous sulfate > alum > tin. It was obvious that color yield gradually decreased when approached from ferrous sulfate to tin. Again, among the four different combinations of mordants, the order was found to be ferrous sulfate-alum > alum-tin-tannic acid > ferrous sulfate-alum-tin > alum-tin.

The addition of ferrous sulfate mordant increased the greenness quality 21.58 % when compared with the reference dyed sample. Tin reduced 22.23 % redness while tin-CT increased 34.05 % redness of the reference dyed sample. Again, from b* values, it was noticed that all the ferrous sulfate mordanted samples were bluer than the reference samples while tin-CT and alum-tin-TA mordanted samples increased yellowness of dyed fabric. The color saturation value (C*) were found to be least in ferrous sulfate mordanted sample (8.7) whereas the values were found to be maximum in the case of alum (32.3) and tin-CT (32.6) mordanted samples. Moreover, the hue angles lie within 67.8° to 83.7°, so all of the dyed samples were closer to yellowish shade than the reddish. Higher color difference (∆E CMC) was noticeable between reference and ferrous sulfate mordanted samples, and the difference reduced from ferrous sulfate to alum and then alum to tin as shown in Table 6.

The presence of hydroxyl or carbonyl groups in dye structure is capable to form metal complex with the positively charged metals. Dye anions and metal cations have strong attraction towards positively charged amino and negatively charged carboxyl groups of silk, respectively. Hence, they form ionic bonding between dye and fiber, metal and fiber, and finally dye and metal ions. The dye-metal complex also forms coordinate bonds with the uncharged amine (−NH2) groups of silk as shown in Fig. 4. In addition, one molecule of dye can form a bond with one site of fiber molecule while one molecule of mordant can form bonds with two or more molecules of dyes. Therefore, these are some of the different features indicating application of mordants increased the color yield (Bhattacharya and Shah 2000; Temani et al. 2011; Uddin 2014).

Structure of mangiferin with ferrous sulfate on silk

Again, ferrous sulfate as a transition metal having coordination number 6 forms a large number of complexes with the dye molecules (Mongkholrattanasit and Punrattanasin 2012). As a result, when they interact with the silk fiber, some coordination sites remain free, and at that time, amino and carboxylic groups on the fiber can occupy these free sites. Thus, ferrous sulfate can form a ternary complex on one site with the fiber and in another site with the dye (Fig. 4). This strong coordination tendency can enhance interaction between the fiber and the dye (Bhattacharya and Shah 2000). This resulted in higher dye uptake as well as shade change due to mordanting with ferrous sulfate (Uddin 2014).

In contrast, aluminum and tin salts formed weak coordination complexes with the dyes. This tends to form quite strong bonds with the dye molecule but not with the fiber (Cotton and Wilkinson 1972). Thus, they block the dye and reduce its interaction with the fiber. This is the reason behind the lower K/S values in the case of aluminum and tin salts than those obtained from ferrous sulfate. Moreover, CT as an assistant increased the color yield from 11.16 to 13.19 when used with tin. CT is chemically potassium hydrogen tartrate which can be used in addition to dyes and mordants to change the pH in order to change colors and to help the absorption of the mordant metal (Mortazavi et al. 2012).

Fastness results

Washing fastness

The results of washing and light fastness of the dyed fabrics are shown in Table 7.

Table 7 Washing and light fastness of dyed fabrics

The unmordated dyed silk showed color change rating of 4. This can be explained that the good fastness to washing for the sample dyed without mordant was due to the affinity of coloring component through H-bonding and van der Waals forces. Using mordants, the color change ratings were found to be within 3/4 to 5, where a rating of 5 (excellent) was found using tin-CT mordant. The ratings were found to be 4/5 in the case of using alum and alum-tin. So it can be said that the overall ratings of color change were good. As wash fastness is influenced by the rate of diffusion of dye molecules and state of dyes inside the fiber, dyes has a tendency to aggregate inside the fiber. Thus, their molecular size is increased resulting in good wash fastness. In addition, in the case of mordanted samples, complexing with mordant also has the effect of insolubilizing the dye, making it color fast.

On the other hand, the color staining ratings were found to be from 4/5 to 5 for all the dyed fabrics, except when ferrous sulfate and its combinations were used as mordant. There were very slight staining observed on to the adjacent wool fiber of the multifiber fabric in the case of ferrous sulfate and its combination samples where the ratings were 4 and almost no staining on the other fibers of the multifiber fabric.

Light fastness

Light fastness as shown in Table 7 was found to be better, and among those, the lowest ratings attained were 5 in the case of tin and alum-tin combination while the unmordanted dyed fabric showed a rating of 6.

In the case of metallic mordants, ferrous sulfate mordanted samples dyed with the mango leaf extracts showed excellent light fastness. This happened due to the formation of a complex with transition metal which protected the chromophore from photolytic degradation. The photons sorbed by the chromophoric group dissipated their energy by resonating within the six-member ring thus formed and, hence, protecting the dyes. Thus, ferrous sulfate can bind with more dye molecules than alum or tin. During exposure to light, the fabrics mordanted with ferrous sulfate, alum, or tin may have the same number of dye molecules destroyed. But as the fabrics mordanted with ferrous sulfate had deeper shades due to bonding with more number of dye molecules, it seemed to fade less compared to the fabric mordanted with alum or tin.


This study was planned in search of greener alternative to satisfy the consumers’ growing demand of eco-friendly products, and progress has been made with this study in the use of mango leaves extracts. The maximum relative color strength of the extracted dye liquor was found to be at pH 10. But the extracted dye liquors have shown good pH stability in acidic conditions. It was shown that different fashion hues were obtained on silk fabric from the same dye extract using mordants and their combinations. Again, color yields were found to be influenced by the addition of mordants. In single mordanting, the order of color yield was ferrous sulfate > alum > tin. In combined mordanting, the order was ferrous sulfate-alum > alum-tin-tannic acid > ferrous sulfate-alum-tin > alum-tin. Other color values were also found to be influenced due to mordanting. Washing and light fastness properties were found to be from good to excellent in most of the cases. Thus, on the basis of the results, it can be said that mango leaves have good scope for application on silk fabrics.
