Abstract
The application relates to the production of a soiled fabric, and more particularly to a method of manufacturing a standard carbon black soiled fabric for performance testing of washing machines. Water is adopted herein as the solvent to prepare a soil, which renders this method safe, environmentally friendly and economical. Moreover, this method introduces a fully-automatic continuous rolling-suction tentering and setting machine to control the pressure of the padder, the drying temperature, the air volume of the fan and the speed of chains, which reduces the manual intervention, achieving a highly-automatic printing and dyeing process. The reflectivity at four points on both sides of the standard carbon black soiled fabric according to the invention is 95% or more.
