The textile industry is a sector completely dependent on water for its full functioning; on the other hand, water represents a very high cost in the production process. The textile chemical processing area is mainly responsible for the large consumption of water. On the opposite side of this high consumption there is an evident water crisis worldwide. That fact has led to many problems to textile companies, mainly for the preparation, dyeing and printing sectors. This present work focuses on an ecologically friendly alternative for cellulosic fiber dyeing processes using seawater. Dyeing cotton fabrics with reactive dye in three primary colors (blue, yellow and red) was performed, and the results compared with processes using distilled water. Samples dyed with seawater exhibit good uniformity, intense color (color strength – K/ S) and excellent washing and rubbing fastness properties compared to the conventional process. It was possible to observe also that the use of seawater did not affect the mechanical properties of the substrate. Thereby, it was verified that the use of seawater presents as a potential and important alternative to applications in the textile dyeing process.

In recent years, the use of low-environmental impact biotechnology giving rises to new types of treatment in the textile industry. From the environmental point of view, particularly the textile dyeing process constitutes a major pollution problem due to the variety and complexity of chemicals employed. In most industrial vat and indigo, sulphur dyeing processes, all of them are reduced mainly using sodium dithionite. This process produces large amounts of hazardous by-products which increase the costs for waste water treatment. Hence, many attempts are being made to replace the environmentally unfavorable sodium dithionite by ecologically more attractive alternatives, such as organic reducing agents or catalytic hydrogenation and natural reducing agent. In this paper ,a natural reducing agent is introduced that comes from a plant and have been studied on the substance for comparison it with sodium dithionite on vat, indigo and sulphur dyeing on cotton fabrics. The color strength of the samples was analyzed by Reflective Spectrophotometer and the color fastness of them was investigated. The results show that, the use of natural reducing agent in natural indigo dye and sulphur dye is better and for the rest of them has almost good advantage, but it cannot reduce synthetic indigo as well as sodium dithionite. Therefore, with introducing the substance, consumption of chemicals is minimized and vat, indigo and sulphur dyeing should be environmental.

AbstractThe conventional dyeing process requires a substantial amount of auxiliaries and water, which leaches hazardous colored effluents to the environment. Herein, a newly developed sustainable spray dyeing system has been proposed for cotton fabric in the presence of reactive dyes, which has the potential to minimize the textile dyeing industries environmental impact in terms of water consumption and save significant energy. The results suggest that fresh dye solution can be mixed with an alkali solution before spray dyeing to avoid the reactive dye hydrolysis phenomenon. After that, drying at 60–100 °C, wet fixation treating for 1–6 min, and combined treatments (wet fixation + drying) were sequentially investigated and then dye fixation percentages were around 63–65%, 52–70%, and above 80%, respectively. Following this, fixation conditions were optimized using L16 orthogonal designs, including wet fixation time, temperature, dye concentration, and pH with four levels where the “larger-the-better” function was selected to maximize the dye fixation rate. Additionally, the color uniformity and wash and rubbing fastnesses were at an acceptable level when both treatments were applied. Finally, the dyes were hydrolyzed after wet fixation, and the hydrolysis percentages were enhanced after the drying process.

To develop an online monitoring and control system for textile dyeing process, an optical fibre sensing system was designed and developed. This paper focused on the measurement of reactive dye concentration in dyebath using the optical fibre sensing system. The optical fibre sensors were proved to be practicable to measure the dye concentration in the dye concentration range during the dyeing process. The measured data was compared with the calculated value, and the linear relation of absorbance to dye concentration was examined. The experiment included single dyes and mixture with double dyes. Dyes concentration measurement accuracy was discussed. The results show that the absorbance is proportional to dye concentration within actual dyeing concentration range. Measured data of dyes concentration well matched the calculated value. The limitations and the approach for improving this optical fibre sensing system were discussed.

Eco-friendly textile dyeing with natural dye is a global soaring interest for avoiding environment pollution incurred by synthetic dyes. This study attempts to compare the dyeing properties of cotton knitted fabric dyed with banana floral stem (BFS) sap and reactive dye. Natural dye i.e. BFS sap was extracted from the species of Musa sapientum by roller squeezer machine. The recipe of reactive dyeing was selected to match the exact shade with the natural dyed specimens. Conformation of the dye molecule fixation onto fiber surface was assured by FTIR-ATR spectra. Comparative analysis were carried out in response of degree of color levelness, color fastness to water, washing, perspiration, rubbing, light and effluent qualities. The economic viability of natural dyeing was also estimated. The specimens dyed with BFS sap have excellent color levelness and color durability characteristic alike reactive dye except light fastness properties. Moreover, natural dyeing costs were almost half of the reactive dyeing. Finally, this inquiry forecasts a less time, energy and water consuming, economical and ecofriendly dyeing process which could be deployed as replacement of reactive dyes with a few compromises.

Textile Dyeing Wastewater

An environmental problem facing the textile industry is the coloured effluent from the dyeing of cellulosic fibres with reactive dyes. Reactive dye loss during dyeing operations is about 10 to 40 %, indicating the need to learn more about the fate of these dyes. Increasing environmental regulations are driving technical innovation to manage this problem. Good analytical techniques for the separation and detection of reactive dyes and their derivatives are necessary for monitoring dye-house effluent, as well as in the optimisation of dye synthesis, purification, formulation and application.

Dyeing Finishing (DF) textile industries which consume a lot of energy, chemicals, water, etc., then produce a lot of wastewater which creates significant environmental problems, can be anticipated by applying Cleaner Production. This paper is presented to discuss the technical modification process of dyeing production machines, which reuse process wastewater to save water and energy consumption in the production process. For that reason, there are three steps taken. First, understand the process flow of the textile dyeing industry. Second, understand in detail the dyeing process of the Jet Dyeing (JD) machine. Third, implement steps on the floor, focusing on the JD machine, starting from the initial conditions until the third step. As a result, savings in water consumption per day for 10 JD machines were achieved by almost 50 %, with details; at the initial status 700 000 L, 600 000 L in the first step, 430 000 L in the second step, and finally 400 000 L in the third step. A similar action can be carried out in other processes, such as washing, de-sizing, or in other industries which also consume a lot of water and energy.

Abstract BackgroundNatural dyes used since historic times for coloring food, leather, textile fibers, and paint body parts. The use of natural dyes has suffered drastically under the influence of modern technologies in the textile industry and socio-economic changes. Hence, ethnobotanical studies of indigenous dye plants and dyeing craft in local communities are urged to protect their potential ecological and economic value. MethodsWe conducted semi-structured surveys on dye plants and traditional craft in 11 Monpa villages of Mêdog County, South-east Tibet, China. The cultural significance of local dye plants was evaluated by an index of cultural importance (CI). Field research was conducted to record the indigenous madder (the root of Rubia wallichiana Decne.) dyeing craft. An experiment was performed with aqueous extract and ethyl alcohol extract of residue remained after water extraction. These two dye solutions were respectively used to dye two fabrics with two biomordants and two metallic mordants by three mordanting methods. We evaluated color properties that were characterized by physicochemical evaluations using UV-visible spectroscopy and FTIR analysis. The dyed fabrics were evaluated by indicators of color strength and fastness including washing, rubbing, and perspiration. ResultsAltogether 15 species belong to 12 families were listed as dye plants, which were used in cloth and food dyeing. The CI of R. wallichiana was highest. Monpa ethnic group used madder directly or with metallic mordants. It was found experimentally that biomordants and metallic mordants were comparable in improving the dyeing properties of indigenous madder. The dyeing properties of both extracts of madder were equal or ethyl alcohol extraction was marginally better.ConclusionsUse of dye plants and indigenous knowledge of dyeing still present in the Monpa ethnic group. Our experiment revealed the feasibility of enhancing the dyeing property and reuse of the residue from madder dyeing. The improved dyeing and reuse of residue can improve the ecological and economic benefits of local meanwhile provide basic application research for the subsequent commercialization of plant dyes.
