“…Natural dye was extracted from Cassia singueana plant was successfully used in dyeing of silk fabric in the presence of Aloe Vera juice as natural mordant [8]. Tanned leather materials were dyed using extracted natural dye from this plant in the presence of natural mordants extracted from Aloe Vera and mango bark [9]. The possibility of using extract of bark of mango tree (Mangifera indica) as a mordant to dye cotton fabric with natural dye (bitter leaves) has been investigated by Wangatia [10].…”

Dyeing of textiles with natural dye was started in the early stage by the traditional dyers. In this century, a global awareness is already in place favoring the use of natural resources for protecting the environment and earth from pollution and ecological imbalances. In this study fully, environmental friendly dyeing of wool fabric was investigated using natural dye and natural mordant extracted from Cassia singueana plant and mango bark respectively. Wool fabric was dyed with Cassia singueana extract using different combinations of dyeing temperature, time, pH and concentration of extracted dye solution. Color strength, CIE L*a*b* and fastness properties (washing, rubbing and light), were investigated. The fastness property results of all dyed wool fabric samples with Cassia singueana plant extract were in the range of Good to excellent.

“…The rate of 4/5 on dry basis implies that leather has good to very good fastness, while the rate of 5 showed very good fastness on the finished leather (Çolak and Ortafidan, 2016;Berhanu & Ratnapandian, 2017). It was observed that the higher parts of gambir in the finishing process did not increase the wet and dry rubbing fastness.…”

The discovery of natural local resources for tanning and coloring agents are growing dramatically to sustain a cleaner leather manufacturing technology. Gambir (Uncaria gambir Roxb) has been found potential as tannin and dyestuffs for leather and textile industry. Therefore, to explore these issues, a combination tanning and finishing system were evaluated to observe the efficiency of this extract on leather processing. A combination tanning system based on chrome or glutaraldehyde – gambir and followed by gambir as coloring agent with different concentrations (100 - 200 parts/L) have been applied. In this FTIR (Fourier-transform infrared spectroscopy) analysis of gambir extract showed the presence of phenolic hydroxyl group. Our results revealed that chrome - gambir and glutaraldehyde - gambir finished leather product with 150 parts/L of gambir extract showed excellent rub fastness, color fastness to perspiration and washing. Most of the result values obtained were generally at satisfactory levels which were between 3/4 and 5 fastness values. Visual evaluation reported that chrome-gambir finished leather product with 150 parts/L of gambir extract exhibited better uniformity of colour fastness.

“…The high temperature degrades and unstabilize the desired polyphenol compounds. Opposite to this the low temperature slows downs the color extraction (Berhanu & Ratnapandian, 2017;Khoo et al, 2017). This material also occupies the space and hold high amount of water so, the solvent ratio is kept from 1:100 to 1:200.…”

Coconut is used throughout worldwide in various rituals, festivals and in food. A huge amount of unused parts of coconut such as fibrous husk and shells are thrashed every day. The present study illustrates the sustainable use of fibrous husk as a source of natural dye. Hence, in order to improve the dye yield, various dye extracting factors were optimized with the help of statistical software. The RSM based Box Behnken approach for optimization was found effective which increases dye yield up to 37%. The analysis of the model implies that the model fits well for all the four factors and found to be significant. All the factors M: L ratio, temperature, Time and pH were found influential in the dye extracting process. The system also helps to improve the yield for desired pH to obtain multiple hues. The optimized parameters to improve dye yield were M:L ratio of 1:130, temperature 80°C, time 250 minutes, pH 9.3.
