This standard specifies the method for determining the pH adaptation range of the dyeing bath when cation dyestuff dyes acrylic fibers. This method evaluates the pH adaptation range of the dyeing bath by conducting dyeing tests under different pH conditions to observe the change of dyeing intensity and color light. The standard is applicable to the dyeing process of various types of cation dyestuff and acrylic fibers, and provides an important basis for controlling the pH value during the dyeing process to ensure the conformity and controllability of the dyeing mass. Applicable normative documents and equipment requirements are also detailed in the standard.
