The invention relates to a manufacturing process of contaminated cloths, in particular to a manufacturing process of a sebum-contaminated cloth for evaluating the cleaning performance of a washing machine on oily dirt. In the manufacturing process, water is used as a production solvent for preparing the pollution liquid, unsaturated fatty acid, olive oil and wax (liquid paraffin) are used as mainoil components, a rolling suction tentering setting machine is adopted for printing and dyeing, and manual intervention in the printing and dyeing process is reduced by controlling the pressure of a padder, the drying temperature of a dryer, the air volume of a fan, the chain rate and the like, and the automation degree is high. The reflectivity of four points on the two sides of a sebum-contaminated cloth finished product prepared by the process is between 22% and 28%, and the rate of finished products can reach more than 90%.
