Abstract:
The growing popularity of environmentally-friendly textile manufacturing has started the study of green dyeing methods. Here, emphasis is laid on the issue of the dyeing method on the use of bi-functional reactive dyes on cotton and viscose fabric in terms of water and energy use, and exposure to environment. Effluent, water and chemical usage and fabric performance may be improved through bi-functional reactive dyes, containing both reactive and bifunctional groups. The dyes being studied are cotton and viscose that has been massively applied in the textile industry. Such fabrics have been tested in terms of how they receive color, how these colors are retained by the fabrics, and their environmental friendliness with regard to these new dyes. The comparisons with the traditional dyeing practices are made in order to identify the extent of effluency, discharge into various toxic chemicals, and recyclability in the course of the dyeing procedure. It has been established that bi-functional reactive dyes have the ability of replacing other types of dyeing processes with a lower environmental load without compromising the overall quality of a product or without any side gains in its quality. The boundary of future explorations is a sustainable dyeing methodology technology and its application in the industry, to attain sustainable growth in the textile industry. Through this work, it is imperative to say that bi-functional reactive dyes are necessitated since they are potential technological change of reaction of eco-friendly dyeing that may meet the aspect of global dyeing without compromising its quality. However, further research is needed to make such methods more industrialized and more presentable.
