摘　　要：纺织印染工业中的纤维素活性染色面临的主要问题是高耗盐、高耗水和高排污等。在以废烹饪油为染色介质的研究中,考察了染色机理、烹饪油的去除效率及回用方法等。为扩展其应用范围,本文从固色时间对相对固色率的影响、染料投入量对固色效率的影响、拼色稳定性等方面研究了异双活性基三拼色染料在烹饪油/水二元体系中的配伍性能。结果表明,单个染料在棉布中某时刻的固色量差异较小;随着三拼色染料用量的增加,三拼色染料在棉布上的固色量的总和呈现线性增加;在二元体系中,三拼色染料具有良好的拼色稳定性,有色棉布的常规色牢度未明显发生下降。Up to now,the cotton fiber is still an important textile fiber,and it accounts for about 80%of the global annual output of natural fibers.The main problems of the reactive dyeing technology for cotton fibers in the processes of dyeing and finishing are high salt consumption,high water consumption,high sewage discharge,etc.The relevant costs from the removal of hydrolyzed reactive dyes from the dyed cotton fiber and degradation of hydrolyzed reactive dyes from the dyeing wastewater account for about 50%of the total cost of cotton fiber processing.During the past two decades of the 21 st century,many improvement schemes,including cationic modification technology for cellulose,supercritical carbon dioxide dyeing technology,low-water foam dyeing technology,non-aqueous solvent dyeing technology,low-water solvent dyeing technology,etc.of the reactive dyeing technology for cotton fibers have been proposed.However,the new cotton fiber dyeing technology reported above is difficult to meet the requirements of the dyeing quality,production safety,and processing cost simultaneously.A low-water dyeing technology for cotton fibers with waste cooking oil as the dyeing medium was proposed in our previous research,and the dyeing mechanism,removal efficiency of waste cooking oil and recycling methods of waste cooking oil were investigated.To expand the application scope of the low-water reactive technology with waste cooking oil as the dyeing medium,it is especially necessary to study the compatibility of commonly used hetero-bifunctional trichromatic dye mixture in the waste cooking oil/water binary dyeing system.In the waste cooking oil/water binary dyeing system,almost all the hetero-bifunctional trichromatic reactive dye droplets will enter the surface of cotton cloth from the waste cooking oil phase during the dyeing process.Firstly,the trichromatic reactive dye samples were taken at different fixation times during the cotton fibre dyeing process,and the effects of the fixation time on the relative rate of hetero-bifunctional
