"Widthwise setting is a textile treatment process aimed at stretching fabric and fixing its shape under specific conditions, providing the fabric with the necessary dimensional stability and form. This process typically involves passing the fabric through a series of stretching and setting devices to ensure that the fabric retains its original shape during use, preventing deformation or shrinkage. Coal is used in steam and thermal oil boilers to generate steam and higher operating temperatures, respectively. According to the clean production report from the surveyed company, the consumption ratio of coal between the two types of boilers is 17:1. The processes of singeing and widthwise setting both require coal consumption through a thermal oil boiler to heat gasoline for providing oil temperature, assuming a consumption ratio of 1:1. Gasoline, as a heat transfer medium, circulates through the corresponding pipelines with minimal loss and does not produce corresponding pollutant emissions. The material usage and pollutant emissions from the gasoline production process are evenly distributed between these two processes." When utilizing this data set for Life Cycle Assessment, consider the ratio of coal consumption between steam and thermal oil boilers as 17:1 according to the surveyed company's clean production report. The coal consumption for singeing and stenter shaping should be assumed as equal due to the heating of oil through thermal oil boilers. Gasoline, used as a heat transfer medium circulating in pipelines, shows negligible loss and does not produce pollutant emissions. Allocate the material use and pollutant emissions from gasoline production evenly between these two processes. This unit process data is based on a case study of a printing and dyeing company located in Changshu, within the Yangtze River Delta economic zone in Jiangsu Province.
