Design Development and Manufacture of Novel Dyeing/Washing Lab Model Machine

Wet processing industries and laboratories were facing dyeing problems because of its unmanageable dye accessories and inadequate technology. Basically, there are a lot of laboratory materials or equipment’s in a laboratory such as beakers, stoves, thermometer, and stirrers which required to be maintained. In the laboratory as a common practice both the dyeing process and the washing process are done separately at different places. This process takes space, cost and time as well. The cost of equipment’s like stove is expensive and moreover very difficult to repair with inadequate supply of spares. Washing is done manually and due to the chemicals used during the dyeing process that causes hazardous to the experimenter, resulting in different skin diseases, breathing problem and so on. The other problem is the amount of MLR is limited, maximum up to 20gm of fabric so it is difficult or might cause uncertainty how the dye reacts on and its evenness or difficult to see if shade variation occurs on that particularly limited small sample. In this study we tried to solve two issues namely high cost due to material such as beaker, thermometer and expensive stoves. The Space minimization and improvement of experimenter safety is the other objective of this project and the design and development of integrated dyeing and washing machine process. Manual washing system was completely eliminated in the new design and methods to increase the MLR of the fabric from to 20gr to 1 kg. The fabrication was conducted at EiTEX laboratory, Bahir Dar University, Bahir Dar. The trails on the effective working of the machine were studied. The designed lab model is robust, easy to operate, safety to experimenter and at affordable cost.
