Benefits of Glauber's salt in textile wet processing

摘要

The Buzz word which is dominating the present decade in the textile processing industry is "Environment aspect". We could not survive without eco friendly approach at the same time we could not change the existing textile processing system completely, which is taxing the environment heavily. However, we can modify processes in such a way that causes less pollution load and are reusable. By keeping an eye on this objective, Textile Research and Application Development Centre (TRADC) carried out a study by using Birla's Glauber salt, which is a byproduct of Birla Cellulose's viscose manufacturing process. In this study, emphasis is given on fabric dyeing by using Glauber salt and its comparison with common salt and vacuum salt. Moreover, pollution load caused by addition of all salts are comparatively analyzed. After extensive experimental trials, TRADC got positive results not only in terms of environmental issues but also from fabric processing point of view. The key things like prevention of premature hardness of the dyestuff, low TDS level, less effluent load and better depth of dye shade are achieved during various trials.
