1、实验
织物：18支棉气流纱园形针织物175g/m2
化学品：NOBS(P&G公司)
TBCC(按文献15合成)
润湿剂Kieralcnjer B conc(BASF)
稳定剂Prestogen N-D(BASF)
实验：按中心组合设计，取3因子与5水平，具体安排如表11所示
表11 实验设计的代码与水平
因子符号 | 因子 | 代码及水平 | ||||
-1.68 | -1 | 0 | +1 | +1.68 | ||
Xl | 温度(℃) | 60 | 70 | 85 | 100 | 110 |
X2 | NaOH(25%)(g/L) | 0.05 | 0.90 | 2.15 | 3.40 | 4.25 |
X3 | 活化剂(mmol/L) | 0.15 | 2.40 | 5.70 | 9.00 | 11.25 |
注:漂白液中含润湿剂lg-L,H2O2 (35%W-W)6.4g-L,浴比：10:1。
二种活化剂(TBCC-NOBS)各进行18次试验，试样白度测定结果如表12所示
