This article will discuss natural dyes’ role, from colouring the cotton fabrics with some functionality to harvesting sunlight in the dye-sensitized solar cells. Natural dye colourants are identical to the low light- and wash-fastness. Therefore, an approach to improving the colourant’s physical properties is necessary. Colouring steps employing silica nanosol and chitosan will be presented. The first part will be these multifunctional natural dye coatings on cotton fabrics. Then, functionality such as hydrophobic surfaces natural dyed cotton fabrics will be discussed. Natural dyes are also potential for electronic application, such as solar cells. So, the second part will present natural dyes as the photosensitizers for solar cells. The dyes are adsorbed on a semiconductor oxide surface, such as TiO2 as the photoanode. Electrochemical study to explore natural dyes’ potential as sensitizer will be discussed, for example, natural dyes for Batik. Ideas in improving solar cell efficiency will be discussed by altering the photoanode’s morphology. The ideas to couple the natural dyes with an organic–inorganic hybrid of perovskite and carbon dots are then envisaged.

Mordant Dyeing

A new source of natural dyes, which possessed antibacterial and UV protection properties, was proposed. Natural dyes were extracted from Fuji apple peel. The extract contained two anthocyanins and five quercetin glycosides. Silk and cotton fabrics were dyed using the extract with and without six types of mordants: Mg2+, Ca2+, Al3+, Ti4+, Fe3+, and Cu2+. The properties of the dyed fabrics were investigated by various means. The K/S values were used to show relative color strength of the dyed fabrics and the CIELAB color system was used to show the color hue of the dyed fabrics. The crystallinity of the silk was lower than that of the cotton. The silk was dyed deeper than the cotton regardless of the dyeing conditions, including dyeing temperature, dyeing period, and solution pH. This result comes from the existence of carboxyl and amino groups and low crystallinity of silk fibers. Fabrics with various colors, including pink, green, brown, and gray, were obtained by mordant dyeing. The dyed fabrics had splendid performance; that is, antibacterial and UV shielding properties. Color fastness to washing (color change) was comparably low but was enhanced with Ti4+ and Fe3+ mordants.

In this study, the ultraviolet protective properties of the cotton fabrics dyed with natural dyes were investigated. It was observed that cotton fabrics dyed with natural dyes could absorb about 80% of the ultraviolet rays. It was demonstrated that the UV-protective effects were strongly dependent on the absorption characteristics of natural dyes for UV radiation.

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.

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.
