GB/T 4464-2016 specifies the determination method of dyestuff swimmability. The standard specifies the materials required for the experiment, such as specific fabrics, dye solution, etc. The experimental process is strictly controlled, including pre-dyeing preparation, condition setting during the dyeing process, and drying. By observing the distribution of dyestuff on the dyed fabric, the degree of dyestuff swimmability is evaluated by rating method. The standard provides a unified measurement standard for dyestuff manufacturers and the printing and dyeing industry, which helps to accurately judge the migration characteristics of dyestuff during the dyeing process, ensure the Stability and uniformity of the dyeing mass, and promote the standardization of dyestuff and the printing and dyeing industry.
