Natural dyes extracted from natural sources are likely to be less harmful and more eco-friendly than synthetic dyes. In this study, cotton fabric was dyed with natural dyes extracted from Java plum fruit (Syzygium cumini). Dyeing was accomplished with or without mordanting agents using simultaneous and post-mordanting methods. The color of the treated substrates was investigated in terms K/S and CIELAB values. In addition, the attenuation co-efficient and solubility in organic solvents of the extracted dyes were determined. The wash and rubbing fastness of the dyed fabrics were good to excellent. Deep shades were obtained by post mordanting method with ferrous sulfate, whereas alum treated fabrics produced brighter shades with excellent fastness. Java plum fruit is available in many countries and offers a possible substitute for synthetic dyes.

Natural dyes are environmentally friendly and have become important alternatives to synthetic dyes in some dyeing products. Therefore, better extraction and dyeing techniques need to be developed for the dyeing process of natural dyes. In this work, cotton fabric was dyed using turmeric extraction solution under an ultralow liquor ratio (materials to liquor ratio of 1:5) and ultrasonic-assisted conditions. Dye extraction using different dispersants and pH values has been investigated and three-factor-three–level Box–Behnken design was employed to explore the dyeing conditions. It was found that sodium dodecyl sulfate systems and ultrasonic waves can effective improve the dyeing depth under neutral condition. The K/ S value can reach 2.53 with ultrasonic power of 200 W, dyeing time of 30 min and temperature of 40℃. Scanning electron microscope images showed that the application of ultrasound did not cause obvious fiber damage. The developed technique could be used in the textile industry to make dyeing cotton fibers with natural dyes more sustainable than it is at present.

Harmful Effects

The main idea of extracting dyes from plant (natural) sources is to avoid the environmental pollution. Natural dye from plants has been given much interest in recent years due to the threat and harmful effects are used by synthetic dyes and environmental awareness created by researchers. The drawback of synthetic dyes is that they are not durable as they do not completely fix on all kind of fabric and remaining dyestuff drained into rivers, becoming the cause of water pollution as well as they cause diseases in human being like cancer and allergies. On the other hand, natural dyes are eco-friendly and find use in the colouring of textiles, drugs and cosmetics etc. Owing to their non-toxic effects, they are also even used for colouring various food products. Mordents are used in natural dyes which enhance the colour of dye and stick it on fabric. Due to lack of availability of precise technical knowledge on the extracting and dyeing technique, it has not commercially succeeded like the synthetic dyes. Hence, the present study was planned to isolate eco-friendly dyes from the bark of the plants (Ziziphus jujube Mill., Albizialebbeck L., Cordia dichotoma G Forst., Ficus benghalensis L. and Cassia fistula L.) and the roots of Ficus benghalensis L. Later on the dyes were applied on silk fabric by using metamordating technique. Then fastness properties like rubbing, heating, washing and sunlight were evaluated by using gray scale. F. benghalensis showed excellent fastness properties. Z. jujube showed series of colour variations on silk. Therefore, the bark and root of these plants can be successfully used for dyeing of silk. Natural dyes worldwide should be increased to prevent us from pollution and other harmful effects.

Cielab Color

Silk and cotton fabrics were dyed using the extract from blackcurrants, and the properties of the dyed fabrics were investigated. The natural dyes present in the blackcurrants were identified as four types of anthocyanins, i.e. delphinidin-3-glucoside, delphinidin-3-rutinoside, cyanidin-3-glucoside, and cyanidin-3-rutinoside. The colors of the fabrics dyed with and without five types of mordants, including Mg2+, Ca2+, Al3+, Fe3+, and Cu2+, were measured and expressed according to the CIELAB color system, Δ E* value, and K/ S value. The affinity of the extracted dye for the silk fabric was higher compared with that for the cotton fabric. The crystallinity of silk was lower than that of cotton. The fabrics dyed with blackcurrants had UV shielding ability, especially at 330–400 nm, and antibacterial properties. Although color fastness to light and washing (color change) was not sufficient, treatment with Mg2+, Fe3+, and Cu2+ mordants could enhance the color fastness.

Purpose The majority of the synthetic dyes have been found to be non-biodegradable, toxic and carcinogenic. As a result, there has been a growing trend toward the use of natural dyes as alternates to synthetic dyes. This shift calls for more research to come up with more sources of natural dyes to satisfy their increasing demand. Euclea divinorum plant has been used traditionally as a source of dye, however, its textile dyeing properties have not been studied. This study aims to determine the textile dyeing properties of E. divinorum extract. Design/methodology/approach Optimization of dyeing conditions of Euclea divinorum natural dye extract on the cotton fabric was done using response surface methodology (RSM). The combined effects of examined dyeing conditions on the relative color strength (K/S) were studied using a central composite experimental design. Analysis of variance (ANOVA) was used to determine the significance of the statistical model generated for the study. Mordanting effects were measured using standard ISO wash, rub and lightfastness tests. Findings The optimum dyeing conditions were found to be 68 min, pH 3.3 and 82°C with color strength 0.609. Temperature and pH showed some interaction effects during the dyeing experiments. The predicted optimum K/S value was validated experimentally using the optimum conditions and was found to be in agreement with the experimental values. All the metallic mordants used enhanced the color strength and provided a variety of brown shades, therefore, a suitable alternative for the toxic synthetic dyes. Originality/value Optimization of dyeing conditions of Euclea divinorum dye on cotton using RSM and mordanting at optimal conditions has not been done elsewhere.

Kepentingan meningkat untuk pewarna semulajadi bermula beberapa tahun lalu tetapi di pihak pengguna, manfaat tersebut hanya mula dirasai. Pewarna asli dianggap sebagai pewarna mampan dan mesra alam; mereka boleh menghasilkan warna yang berbeza warna dan mempunyai ketahanan luntur yang lebih rendah daripada pewarna sintetik. Oleh itu, kertas kerja ini dikaji pada sifat kubu daripada pewarna yang diekstrak daripada kacang belalang dan buah-buahan asam buah.Warna-warna ini dipetik menggunakan kaedah berair dan pelarut dan telah digunakan di dataran terluntur ditenun kapas dan sutera kain.Yang digunakan bagi pedas meningkatkan penembusan warna (pewarna) dan sampel dicelup telah tertakluk kepada ujian kubu (membasuh, menggosok, peluh & ujian cahaya). Perbandingan analisis kepada tahap pewarnaan telah direkodkan dan ujian kubu baik daripada analisis membuktikan bahawa; warna boleh digunakan sebagai pewarna pada kapas dan sutera kain.   An interest for natural dyes increased several years ago but on the part of the consumers, the benefits are just beginning to be felt. Natural dyes are considered as sustainable and ecofriendly dyes; they can produce different shades of colours and have lower colour fastness than synthetic dyes. Therefore, this paper researched on the fastness properties of colorant extracted from locust beans and tamarind fruits pods. The colours were extracted using aqueous and solvent methods and were applied on bleached plain weaved cotton and silk fabrics. The use of mordant increased the penetration of the colours (dyes) and the dyed samples were subjected to fastness test (washing, rubbing, perspiration & light test). Comparative analyses on the degree of staining were recorded and good fastness test from the analysis proved that; the colours can be used as dyes on cotton and silk fabrics.

Recently many batik industries owner have switched to using natural dyes because synthetic dyes in the long time have a negative impact on the environment. Natural dyes that are widely used are mahogany (Swietenia Mahagony L.) bark dyes. In the process of coloring batik fabric, there is stage of fixation. Fixation is the stage of binding the color with the fixator. There are three types of fixators used, namely alum (Al2(SO4)3.12H2O), calcium oxide (CaO) and ferrous sulphate (FeSO4) with certain concentrations. The owner of batik industries don't know yet the concentration of a strong and optimal fixator for binding natural dyes in batik fabric. The purpose of this study is to determine the type of strong fixator and optimal concentration of fixator for binding natural mahogany dyes on batik fabric. The owner of batik industries usually use an estimated concentration of 30 g / L to 100 g / L. In this study, the variables are 30 g / L, 60 g / L and 90 g / L in each type of fixator to test the color aging value. and color fastness to rub wet and dry. Judging from the value of R% (color aging) and color fastness test against wet and dry rubbing, it can be concluded that alum and calcium oxide are strong fixators that used with mahogany dyes and the most optimal concentration of alum and calcium oxide is 60 g / L.
