"Reactive dyes are a type of dye capable of forming a covalent bond with fibers, particularly well-suited for dyeing cotton fibers. They typically require application under alkaline conditions to ensure the dye thoroughly binds with the fibers, enhancing the permanence of the dyeing effects. In the roller dyeing process, research indicates that the energy consumption for dyeing with reactive dyes constitutes 47% of the total process energy consumption." When utilizing this dataset for Life Cycle Assessments, it is necessary to properly allocate energy consumption based on the reported proportion of energy use for dyeing relative to the total process energy consumption, which is 47%. Consider the reported coal consumption ratio for the two types of boilers, 17:1, in your calculations. It is essential to ensure methodological consistency in system boundaries by assessing the steam usage in each step of the process according to the provided steam usage ratio of 2:1:1:1:1:2. This data should be contextualized within the regional economic conditions of the Changshu area, located in the Yangtze River Delta economic zone of Jiangsu Province.
