2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. General conditions for determination of dye dyeing

3 terms and definitions

The following terms and definitions apply to this document. 3.1 Reactivity reactivity Describe the parameters of the chemical reaction rate of reactive dyes and cellulose fibers.

4 principle

The reactive dye is dyed on the cotton fiber, and the higher the fixation rate in a short time, the faster the reaction rate of the reactive dye and the fiber is. Through the test The reactivity of the reactive dye can be determined by determining the fixation rate for a short period of time. The reactivity of the reactive dye was measured at 5 min fixation rate.
