dyed material in the alkaline solution, controlling the liquid carrying rate and drying; and (2) performing non-aqueous medium dyeing of the reactive dyes, namely performing non-aqueous medium dyeing of reactive dyes on the dried to-be-dyed material, thereby obtaining the finished dyeing product....
Furthermore, the dyeing enthalpy and dyeing entropy of cotton dyeing using reactive dyes in LP and D5 media were positive, which was significantly different from those in an aqueous medium. These properties help to understand and interpret the dyeing properties and behavior of reactive dyes onto ...
REACTIVE dyesFIBERSCOTTONThis study reviews the evolution of and recent developments in non‐aqueous reactive dyeing systems for cotton fibre. As conventional water‐based reactive dyeing causes adverse effects to the environment because of the need for huge quantities of water and chemicals, as well ...
To alleviate these problems, non-aqueous dyeing technology appears as an alternative for improving dye fixation and reducing effluent discharge. Here we used silicone non-aqueous medium to dye a wool fabric. Continuous pad dyeing with reactive dyes was investigated. We optimized the type of ...

The invention provides a high-fixation-rate non-aqueous solvent dyeing method for reactive dyes. The method comprises the following steps: swelling fibers in aqueous solution of an alkaline matter until the liquid carrying rate is 30-200 percent, and drying; mixing the dried fibers with reactive ...
of the good solvents of the reactive dyes to the poor solvents of the reactive dyes is 1:(3-20), and the ratio of the volume of the good solvents of the reactive dyes to the mass of the fiber is (2-50):1 in the unit of mL/g; drying, and finishing dyeing, wherein the good ...
