摘要
优选分散染料和中性染料对涤粘织物进行一浴法染色研究。通过正交试验,确定最佳染色工艺为:分散染料4%,中性染料2.3%,硫酸钠30 g/L,环保载体2 g/L,pH 7,温度100℃,时间40 min。采用该工艺染色的涤粘织物具有较高的染色牢度,耐摩擦色牢度达4~5级,浅色织物耐水洗色牢度可达4级以上,深色织物耐水洗色牢度可达3级以上。与二浴法染色工艺相比,该工艺在获得相同的染色深度和相似的染色牢度时,可节约能源和提高生产效率。
Disperse dyes and neutral dyes are selected for one-bath dyeing of polyester/viscose fabric.The optimal dyeing process obtained by orthogonal test is:disperse dye 4%,neutral dye 2.3%,sodium sulfate 30 g/L,environmental friendly carrier 2 g/L,pH 7,dyeing at 100℃for 40 min.The polyester and viscose fabric dyed by this process has high color fastness:the rubbing fastness can reach Grade 4-5,the washing fastness of light-shade fabric can reach Grade 4 or above,and the washing fastness of darkshade fabric can reach Grade 3 or above.Compared with the two-bath dyeing process,this one-bath dyeing process can save energy and improve production efficiency when obtaining the same dyeing depth and similar dyeing fastness.
