Wastewater color remains due to the non-biodegradable nature of the dyes. However, treatment with ozone can lead to the destruction of the dye molecule, decolorizing thus the textile effluent. In this paper, treatment with ozone in a bubble column reactor resulted in rapid destruction of azo-reactive dyes, utilized primarily for dyeing cellulose fibers. Moreover, ozonation kinetics can be described as a mass-transfer-control process. Combining ozonation with a novel radio-frequency alternating electric field inductance device led to faster destruction of the azo-reactive dyes due to synergetic effects.

Journal of Fashion Technology -  Juniper publishers  Introduction We have always argued that the concept of sustainability invites us to set aside our ideological and institutional assumptions and address global problems and needs with a sense of humility. The size of the sustainability challenges- and, therefore, the potential opportunities for progress-exceed anything that has been faced in the history of mankind. Today, the major challenge is to strike a reasonable balance between usually conflicting issues. And, in the process of striking a reasonable balance, all sectors of society must learn to co-exist and, indeed, to actively collaborate if catastrophe is to be averted and a more ecologically sustainable, socially equitable and economically stable world is to be achieved for a world of up to 9 billion people in the coming decades. And the textile and fashion sectors are not spare from this. Many authors and organizations have analyzed the impact of the tex...

Journal of Fashion Technology -  Juniper publishers  Abstract Natural dyes have been used since long back in various areas such as textiles, craftwork, food colouring and also as medicine. This work was based on expansion of the colour shade that can be obtained from natural dyes for use by the small scale users. The natural dye was extracted from three naturally available plants locally in Zimbabwe using the cold extraction under gravity method. An alcohol was used to extract the dye using a vacuum pump and left to dry. The extracted dye was then used to dye fabric strips using different metals as mordants. From the colour charts generated from the various dyeings it was shown that the shades can be extended for certain plants and in some cases they are not easy to expand. Application of the metal mordants at different concentrations was also found to have an effect on the hue of the dyed fabric strips. The results show that the natural dye from the Mukwa (Pterocarpu...
