深色锦/氨针织物耐湿摩擦色牢度的改善方法

Method for improving the color fastness to wet rubbing of deep colored nylon/spandex knitted fabrics

耐湿摩擦色牢度反映染色织物的染料分子以及其附着物在湿态下通过界面接触摩擦,向测试用标准白布转移的程度。耐湿摩擦色牢度不合格反映织物表面残余染化料较多,需要皂洗固色。不同织物染色需要不同染料和不同固色剂,其原理也不同,改善锦/氨针织物耐湿摩擦色牢度的方法主要有:选择高牢度染料,合理选择固色剂,科学控制固色温度、时间、pH及水质硬度,优化皂洗工艺,选择合适的设备等。

The color fastness to wet rubbing reflects the degree to which dye molecules of dyed fabric and their at-tachments transfer to the standard white cloth for testing by contact and friction through interface interface contact friction in a wet state.Unqualified color fastness to wet rubbing reflects that there are many residual dyes and chemicals on the surface of the fabric,which requires soap washing and color fixing.Different fabrics require different dyes and fixing agents for dyeing,and their principles are also different.The methods for improving the color fastness to wet rubbing of nylon/spandex knitted fabrics mainly include the selection of dyes with high fastness,the reasonable selection of fixing agents,the scientific control of the temperature,time,pH and water hardness,the optimization of soap process,and the selection of suitable equipment.
