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.

In modern world, most of the countries tend to use the eco-friendly concept in many industries to minimize environmental pollution [1]. Synthetic dyes that are used in the textile industry offer more unfavourable and harmful effect to human beings such as carcinogenic, health-hazardous like skin allergies, toxic etc. And also, there is no systematic way to dispose of synthetic waste in the environment. So that it can be harmful to the ecosystem [2]. Therefore, the world tends to use natural dyes instead of synthetic dyes. Natural dyes have many advantages than synthetic dyes such as non-carcinogenic, eco-friendly, non-allergic, non-hazardous to human beings, etc. Natural dyes are mainly extracted from three different sources such as minerals, plants, and insects. Among these, plants are the most abundantly used natural dye source to extract dyes [3]. The main objective of this study was to extract natural dye from areca concinna peels and use extracted dye to dyeing the cotton fabrics.

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.

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.

Ultrasonic Assisted Extraction

The textile industry uses synthetic dyes because they are cheaper and easier to obtain. Moreover, the color availability is guaranteed and more varied. However, these synthetic dyes have a negative impact on health and the environment. The natural dye from avocado (Persea Americana Mill) seeds can become an alternative for synthetic dyes. Polyphenol compounds, such as tannins and flavonoids, are natural color sources found in avocado seeds. The extraction of natural dyes from avocado seeds is carried out by using a non-conventional method, namely ultrasonic-assisted extraction which has great efficiency and short operating time. In this study, researchers examined the parameters that affect the yield of dye extraction from avocado seeds, namely solvent concentration and extraction time. In addition, researchers also conducted qualitative analysis on the pigment content in the yield of extraction using UV-Visible Spectrophotometry and GC-MS tests. The results indicated that the highest yield obtained from avocado seeds was 16.6742% with 90 minutes extraction time using 70% ethanol solvent. Furthermore, if the dye is applied to cellulose fibers, such as the cotton cloth, the color will change depending on the fixator added. Based on the result of the UV-Visible Spectrophotometry test, the avocado seeds contain flavonoids. Meanwhile, from the result of the GC-MS test, the compound with the largest percentage detected in avocado seeds is the 13-Tetradecynoic acid, methyl ester (C15H26O2). The compound contains a chromophore, such as a carbonyl group (C = O) which is a common feature of flavonoids.

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.

Plants, which are the biggest source of natural dyes, have been used as coloring agents since the beginning of humanity. In this study, the usability of eastern groundsel, which is thought to be an alternative for the textile dyeing industry, especially for sustainable and renewable textile production, was investigated. Dyeing processes were performed with different concentrations of dyeing baths of natural dye which is extracted from the crowns of the eastern groundsel (Senecio vernalis) plant. After dyeing, dye flotte concentrations were determined using UV-visible spectrophotometer and the percent uptake of natural dye on cotton fabric was measured Spectrophotometric color analysis of the fabrics was performed and fastnesses of the samples were evaluated. It was found that the coloration of cotton fabrics with the use of Eastern groundsel (Senecio vernalis) in suitable dyeing application conditions could be managed with almost sufficient fastnesses.

P25 TiO2powders were calcined at different temperatures in a muffle furnace in air. The P25 powders before and after calcination treatment were characterized with XRD FTIR, UV-visible diffuse reflectance spectra, SEM, TEM, HRTEM, and N2adsorption-desorption measurements. The photocatalytic activity was evaluated by the photocatalytic oxidation of methyl orange aqueous solution under UV light irradiation in air. The results showed that calcination treatment obviously influenced the microstructures and photocatalytic activity of the P25 TiO2powders. The synergistic effect of the phase structure, BET surface area, and crystallinity on the photocatalytic of TiO2powders (P25) after calcination was investigated. An optimal calcination temperature () was determined. The photocatalytic activity of TiO2powders calcined at was nearly 2 times higher than that of the uncalcined P25 TiO2. The highest photocatalytic activities of the calcined samples at for 4 h might be ascribed to the enhancement of anatase crystallization and the optimal mass ratio (ca. 1 : 2) of rutile to anatase.
