Abstract

Abstract: An investigation of the process involved in the production of and dyeing with indigo based on a CO2/O2 sensor device and a cellphone-camera is reported. The former involves transforming indican to indigo, and the latter the process by which indigo and indigo-white are produced. During the process of indigo production, a clear and positive correlation can be observed between the concentration of gas levels (either the production of CO2 or the consumption of O2) and the final yield. The authors found that for the first time that the change in the concentration levels of CO2/O2 can be used as important parameters for indigo dyeing. The optimal time required to produce indigo can be decided by the change of CO2/O2 concentration level. It is no long should depending on the experience of a craftsperson. Furthermore, the optimal time needed to produce indigo also can be decided by the concentration levels of glucose. The color analysis of indigo dyeing can be performed by using a camera and by calculating the RGB and HSV (hue, saturation, value) values. Graphical abstract: [Figure not available: see fulltext.]
