Chemical Color Stripping of Cellulose Fabric dyed with Reactive dyes
Journal Title: International Journal of Science and Innovative Research - Year 2021, Vol 2, Issue 05
Abstract
Conventionally, the stripping methods implicate high bathing ratios, temperatures and loads of chemicals due to which the fabric strength decreases significantly and these methods were high in cost due to high energy consumptions. Many methods to sort out these faulty dyeing of fabrics has been adapted, such as destructive stripping and desorption stripping etc. In this article, three different techniques have been discussed such as conventional methods of reductive color stripping and advanced stripping methods as oxidative and photo-catalytic color stripping. The purpose of this article is to review the color stripping methods by comparing the color stripping efficiency of these methods which was evaluated by using different parameters such as time, effect of pH, loss in weight and strength of the fabric during the stripping process and the pilling resistance. The results obtained from these methods demonstrated that the conventional method of reductive stripping affects the crystalline of the fabric, harmful towards humans due to the use of harsh chemical usage, time and energy consuming. Furthermore, the oxidative method of stripping found was more efficient as compared to reductive one due to less consumption of energy, water and chemicals. Besides, all of these are novel techniques i.e., photo-catalytic is found to be finest among the all cited techniques as it is more energy conserving and eco-friendly than the others. After stripping the white cellulose fabric moves towards recycling, this helped to overcome the need for textile by giving the astonishing look to the fabric. This article basically highlights the significance of stripping processes and their limitations by providing the opportunities for the new researchers to develop more effective, less time consuming and more energy saver dyeing and stripping procedures to tackle these problems.
