Use advice for data set When utilizing this LCA data, users must pay close attention to the energy allocation amongst various processing stages in the dyeing and finishing of cotton fabrics. The reported coal consumption ratio for steam and conduction oil boilers should be accounted for in the use of coal as an energy source. Additionally, it is crucial to consider that this data is based on specific operations of a survey enterprise located in Changshu, within the Yangtze River Delta Economic Zone in Jiangsu Province. Users must consider regional energy mix and technology levels, and, if needed, adjust the data to reflect local or specific production conditions. Recycling and end-of-life scenarios are not included in this data set, and users need to handle these aspects separately as per their LCA study requirements.

General comment "Mercerization" is a treatment in the printing and dyeing process aimed at applying a silk finishing agent to the fabric's surface, giving it a bright and silky luster. This process typically involves applying the silk finishing agent to the fabric after the printing or dyeing is complete, followed by curing through heating or other means to achieve a smooth and glossy surface.

Technical purpose This industrial process involves the wet steaming cotton dyeing and finishing method used in the textile industry, specifically for printing and dyeing cotton fabrics with mercerization. Mercerization enhances the luster, strength, and dye affinity of cotton. Coal is used in steam and conduction oil boilers to produce steam and maintain high operating temperatures, essential for various stages of textile processing, including scouring, bleaching, mercerizing, raising, width washing, stentering, and pad-dyeing. Steam is utilized for drying the fabric after each of the processes mentioned, with two drying steps for pad-dyeing and one for all other stages. The process is designed to efficiently allocate steam usage among different stages according to the proportion of 2:1:1:1:1:2 based on the assumption that each drying cylinder consumes an equal amount of steam.
