This standard specifies a method for determining the degree of fixation of reactive dyes in pad dyeing, applicable to evaluating the fixation rate after padding onto cotton fabric. The method involves padding the dye solution onto cotton, followed by drying, steaming for fixation, and soaping. The dye is then extracted from both unfixed and fixed fabric samples, and the absorbance is measured using a spectrophotometer to calculate the fixation rate. The standard details the apparatus, reagents, procedure, and calculation formula, providing a unified quality control tool for dye manufacturers and the textile printing industry.
