A study on reducing the color difference between dyeing in the laboratory and dyehouse

Within the scope of the study, it is aimed to examine the laboratory-dyehouse harmony, which is one of the biggest problems in the business, and to minimize the difference. In addition, it is aimed to make the necessary corrections in order to reduce the trials made during the application of the recipes prepared by the laboratory and to prevent the time, labor and dye/chemical consumption lost in this process. For this purpose, dyeing processes were applied to a selected woven fabric containing viscose / cotton / elastane with different recipes in the laboratory and in the dyehouse, and evaluations were made by comparing the color values. The color difference has been tried to be minimized with the applied experiments. In the results of working; it has been observed that darker colors can be obtained by completely removing the caustic from the dyeing recipe in the laboratory and lowering the pH value.
