The value of pH in outlet water was higher than grade- I of Emission Standard (6-9), so this water were not permitted to emit. But a certain quantity of the water could be reused in the working procedure of hydrolyzing calcareousness, and the remains could be reused as washing water or emitted directly after neutralization by acid.

出水的pH值高于一级排放标准的6～9，不能直接排放，但部分出水可回用于石灰消解工序，其余出水经加酸调节后可作为工艺冲洗水或外排。

Cotton and silk fabrics were dyed with natural carminic acid after the Iron ion pre-mordant treatment. The K/S values of the fabrics were characterized. The single factor process experiments were carried out for mordant concentration, temperature and time. The optimal process parameters were mordant concentration cotton: 1×10^(-3mol/L and 10 min at 90℃; silk: 1×10^(-3)mol/L and 10 min at 40℃.

将铁离子前媒染处理后的棉、丝织物采用天然染料胭脂虫酸进行染色，以染色织物的K/S值进行表征，对媒染剂浓度、温度、时间3个因素进行了单因素工艺实验，得到了铁离子前媒染棉、丝织物的最佳工艺参数（棉：1×10^(-3)mol/L， 90℃，10分钟；丝：1×10^(-3)mol/L， 40℃，10分钟）。
