Abstract

A little variation in dyeing procedure applied when fabric dyed with ground water and sea water. When ground water from natural sources used as dyeing medium wetting agents, sequestering agents, anti- creasing agents, salt, soda everything were applied to complete dyeing process. But in case of sea water we didn’t apply sequestering agents so that the hardness of sea water might not be broken. Again Bay of Bengal water contains a lot of salts, so it wasn’t needed to use salts for dyeing with sea water. The main purpose of our research was to find out the differences in several physical and chemical properties of dyed fabrics and to determine whether can be used sea water as dyeing medium for dyeing process. Sea water is available in Bangladesh. Again due to lack of ground water availability the layer of our ground water falls down every year. So, it has become a crying need to find out another alternative source of water to continue our industrial dyeing process. For this purpose we wanted to find out the possibilities and opportunities of using sea water as dyeing medium instead of ground water.
