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

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.

Coconut husk is considered waste and its fibers can be used as a source of natural dyes for textiles. The objective of this research is to obtain natural dyes from old coconut (Cocos nucifera) husk waste fibers through the extraction process. Brown color was produced in the liquid-liquid extraction method. The brown color natural dyes were then used to dye cotton cloth. Three different binding agents were used during the fixation process, i.e. tunjung, naphtol salt, and alum. The coloring results of the natural dye on the cotton cloth were as follow: with alum binding agent the resulting color was light brown (cream), whereas tunjung binding agent produced a greenish brown color, and using napthol salt binding agent produced yellow color. The colored cotton cloths were tested for their color fastness properties against rubbing, soap washing, and sunlight exposure. The measurement scale used was grey scales, which was used to evaluate the color change (color fading) and color staining (color transfer) during color fastness testing. In general, based on the results, the colored cotton cloth using alum as binding agent showed better color fastness properties against rubbing, soap washing, and sunlight exposure compared to the ones using tunjung and naphtol salt binding agents.

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.

<p class="Default">Synthetic dyes have a high environmental impact, especially on waters. The use of natural dyes for textiles provides new hope for ecological improvement. This article is to find out the yield of water extract of white frangipani (<em>Plumeria acuminate</em>) and hibiscus (<em>Hibiscus tiliaceus</em>) leaves-powder, as well as to find out whether the water extracts have potential as textile natural dyes. Natural dyes must have a good quality of fastness. For this reason, the color fastness tests for washing with a launder meter and colorfastness against rubbing with a crock meter are performed. Colorfastness is assessed by comparing color changes to washing with grayscale and color changes due to staining on fabric with staining scale. The rubbing test is carried out on the wet and dry cloth. Cotton and polyester fabrics are samples that will be colored. Fixers used to bind dyes are Al<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>, CaCO<sub>3</sub>, and FeSO<sub>4</sub>.H<sub>2</sub>O. The results show that the water extraction of hibiscus and white frangipani leaves powder gave a yield of 11% (w/w) and 27 % (w/w), respectively. The test of colorfastness against washing showed that both water extract of the white frangipani dan hibiscus leaves has a pretty good average quality in staining scale but less in grayscale. The test against rubbing shows that the type of fixer used affects the quality of the colorfastness, but in general, the water extract of white frangipani leaves gives better quality as a potential of natural dye than hibiscus leaves</p>

Natural dyes obtained from agro-food waste can be considered promising substitutes of synthetic dyes to be used in several applications. With this aim, in the present work, we studied the use of chlorophyll dye (CD) extracted from broccoli waste to obtain hybrid nanopigments based on calcined hydrotalcite (HT) and montmorillonite (MMT) nanoclays. The synthesized chlorophyll hybrid nanopigments (CDNPs), optimized by using statistical designed experiments, were melt-extruded with a polyester-based matrix (INZEA) at 7 wt% loading. Mechanical, thermal, structural, morphological and colour properties of the obtained bionanocomposites were evaluated. The obtained results evidenced that the maximum CD adsorption into HT was obtained when adding 5 wt% of surfactant (sodium dodecyl sulphate) without using any biomordant and coupling agent, while the optimal conditions for MMT were achieved without adding any of the studied modifiers. In both cases, an improvement in CD thermal stability was observed by its incorporation in the nanoclays, able to protect chlorophyll degradation. The addition of MMT to INZEA resulted in large ΔE* values compared to HT incorporation, showing bionanocomposite green/yellow tones as a consequence of the CDNPs addition. The results obtained by XRD and TEM revealed a partially intercalated/exfoliated structure for INZEA-based bionanocomposites, due to the presence of an inorganic filler in the formulation of the commercial product, which was also confirmed by TGA analysis. CDNPs showed a reinforcement effect due to the presence of the hybrid nanopigments and up to 26% improvement in Young’s modulus compared to neat INZEA. Finally, the incorporation of CDNPs induced a decrease in thermal stability as well as limited effect in the melting/crystallization behaviour of the INZEA matrix. The obtained results showed the potential use of green natural dyes from broccoli wastes, adsorbed into nanoclays, for the development of naturally coloured bionanocomposites.

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.
