GB/T 9291-2008 focuses on the field of surfactants, mainly testing the anti-dyeing effect of leveling agents when disperse dyes dye polyester fabrics at high temperature. The standard specifies the experimental materials, including specific polyester fabrics, disperse dyes and various leveling agents, etc. The experimental process is specified in detail, such as dyeing solution preparation, dyeing temperature and time setting, fabric dyeing operation steps, etc. Through standardized testing, the inhibitory effect of leveling agents on dyestuff rate during high temperature dyeing can be accurately evaluated. It provides a scientific basis for the rational selection of leveling agents and the improvement of dyeing mass in the Spinning & weaving printing and dyeing industry, and promotes the technological progress of the industry
