Synthetic dyes are widely used in the majority of the large textile industry. The use of synthetic dyes can cause water pollution from sewage disposal of the textile industry. Some types of synthetic dyes contain heavy metals that are harmful to human health and can damage the environment. With increasing awareness of the current environmental problems, people begin to focus on returning back to natural dyes. These natural dyes can be extracted from various parts of plants, such as leaves, flowers, fruit, wood or stems, and roots. Papaya leaves have the potential to be used as a basic ingredient to make natural dyes due to fairly high chlorophyll content. Therefore, we took the initiative to conduct research on the production of natural dyes from papaya leaf extract. Papaya leaf extract was produced by using a solid-liquid extraction process using two different solvents, ethanol (96%) and n-hexane. From the results of the study, it was found that the most optimum extract results in the extraction process was about 2.20% of the raw material of dried papaya leaves by using ethanol solvent. The prepared cotton cloth was then colored with papaya leaf extract through three simple steps, namely: mordanting, dyeing, and fixation. Fabric staining results then tested its fastness by two methods, namely the rub method and the washing method with soap. From the test results it was found that the fabric which was dyed with papaya leaf extract was not too resistant to fade from rubbing and soap washing. Therefore, further research is needed, such as using other agents during the mordanting and fixation processes.

Potential Use

In this modern era, most of the textile industries used synthetic dyes for coloring their fabrics. The reason why most of textile companies use synthetic dyes is that synthetic dyes are easier to obtain, the availability of colors is guaranteed, vast variety of colors, good color fastness. Nevertheless, the use of synthetic dyes in the textile industries has caused environmental problems if the waste not treated properly. Additionally, synthetic dyes commonly contain chemicals which are not good for human health. They can cause cancer, attack the nerves of the brain, etc. Therefore, most of people now focus on using natural dyes as alternative to subtitute synthetic dyes. Nowdays, in Indonesia, naturally-dyed textile products, such as Batik tulis (using natural dyes) has a high market potential as a superior commodity of Indonesian products to enter the international market. Therefore, to develop the use of natural dyes in the textile industries, it is necessary to explore the sources of natural dyes from various potential natural resources in Indonesia. Most of these natural dyes are coming from the plants. Cassava leaf is widely known and used for cooking by the people of Indonesia. Based on the literature, cassava leaf contains natural pigments such as chlorophyll a, chlorophyll b, xanthophyll, carotene, and anthocyanin Based on this, we took the initiative to conduct research to investigate the potential use of cassava leaves extract as natural coloring substance for coloring fabrics. In this research, Cassava leaf extract has been obtained via solid-liquid extraction process using two different solvents, ethanol (96%) and n-hexane. From this study, it was found that the most optimum extract resulted from the extraction process was about 1.67% with ratio of cassava leaves and ethanol solvent of 1:10. This extract was then used for coloring the cotton cloth. After colored, the cloth was then tested for its color fastness by two methods, namely rub method and washing with soap. From the test results, it was found that the fabric dyed with cassava leaf extract was not much able to withstand against rubbing and washing with soap. Based on this result, further research is needed, such as using other agents during the mordanting and fixation processes

Textile Dyeing

The textile industry is one of the biggest industrial consumers of water especially dye houses which utilize synthetic dyes and other chemicals. Natural dyes are generally environmental friendly and have many advantages over synthetic dyes with respect to production and application. In recent years, there has been an interest in the application of these dyes due to their bio-degradability and higher compatibility with the environment. A review of previous work in the field of applying dyestuffs of natural source as possible textile dyes is given. From an ecological viewpoint, the substitution of chemical dyes by 'natural products' in textile dyeing may be feasible and may represent not only a strategy to reduce risks and pollutants, but also an opportunity for new markets and new businesses which can develop from the inclusion of ecology in trade policy.

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.

Abstract There has been increased interest in the use of natural dyes for textile coloration as alternatives to synthetic dyes, due to the general belief that natural dyes are more environmentally friendly. However, natural dyes have poor affinity for textiles, which can lead to high dye levels in the resultant wastewater. While chlorine treatment has proven to be effective for dye wastewater disinfection and decolorization, this process can also lead to the formation of more toxic degradation products for certain synthetic dyes. On the other hand, little information is available regarding the ecotoxicity of natural dyes and their chlorination products. To advance knowledge in this area, madder was selected due to its historical importance and wide application in the textile industry. Specifically, we sought to characterize the chlorine-induced degradation products of an aqueous madder solution and to assess their ecotoxicity. The main component of the present madder sample was Alizarin (89.8%). Chlorination led to complete decolorization, and 2-hydroxynaphthalene-1,4-dione and phthalic anhydride were identified as key degradation products. Chlorination of madder decreased toxicity to Daphnia similis (microcrustacean) 10-fold and removed the toxicity to Raphidocellis subcapitata (algae), when compared to the parent dye.

Abstract: Dying is a popular practice in textile industry which is prevalent at all parts of the world from the period of ancient civilization. Initially, natural dyes i.e. dye derived from natural resources like vegetables, flowers, minerals, plants etc. were used. Now-a-days, due to technological and scientific innovations synthetic dyes are processed at large scale in the laboratories as it is still one of the most profitable industry globally. However, the rapid utilization of chemicals in textile industry for production of synthetic dyes causes degradation of environment like soil pollution, water pollution etc. Hence, it is necessary to promote the utilization of natural dyes globally. In this paper, the exhaustion of dye extracted from red chillies, one of the most used vegetables same has been studied on cotton fabrics at different temperatures using UV-Visible light spectrophotometer. The colour strength of the fabric before and after application of soap therein are also studied experimentally. Keywords: Natural dye, red chillies, cotton fabrics, exhaustion of dye, absorption.
