In order to prevent light-colored clothes from being stained by dyes released from dark clothes during the washing process, some new-type washing machines have developed the dye transfer inhibition washing program. However, there is no certified reference materials for the test of dye transfer inhibition function. To this end, cotton fabric and reactive dyes are used as experimental materials to prepare standardized samples to evaluate the dye transfer inhibition function of washing machines. Firstly, the single factor analysis method is used to analyze the significance of the dyeing parameters including dye dosage, dyeing temperature, sodium sulfate dosage and sodium carbonate dosage. Secondly, a 4-factor 5-level experimental design and theoretical prediction of the best dyeing parameters are successively carried out through central composite design and response surface method. Two evaluation indicators, the dye release amount of the standardized sample of dyed fabric and the color difference value of the standardized sample of white fabric after washing, are proposed as the response values for response surface analysis to search the optimal dying parameters in theory. The optimal dyeing parameters obtained through response surface analysis are that the dosage of dye is 5.63% (owf), the dyeing temperature is 60 °C, the dosage of sodium sulfate is 93.60 g/L, and the dosage of sodium carbonate is 15 g/L. Experimental results indicate that the standardized samples prepared with optimal dyeing parameters can effectively distinguish the dye transfer inhibition function of washing machines.

棉花标准化样品染色参数的优化用于染料转移抑制程序的洗衣试验。

为了防止浅色衣服在洗涤过程中被深色衣服释放的染料弄脏，一些新型洗衣机开发了抑制染料转移的洗涤程序。但是，没有用于测试染料转移抑制功能的认证参考材料。为此，将棉织物和活性染料用作实验材料以制备标准化样品，以评估洗衣机的染料转移抑制功能。首先，采用单因素分析法分析了染色参数的重要程度，包括染料用量，染色温度，硫酸钠用量和碳酸钠用量。其次，通过中心复合设计和响应面法相继进行了四因子五级实验设计和最佳染色参数的理论预测。提出了两个评价指标，即染色织物标准化样品的染料释放量和洗涤后白色织物标准化样品的色差值，作为响应面分析的响应值，从理论上寻找最佳的染色参数。通过响应面分析获得的最佳染色参数是染料用量为5.63％（owf），染色温度为60°C，硫酸钠用量为93.60 g / L，碳酸钠用量为15 g /升
