Key technologies of clean dyeing of PLA fiber fabric
The dyeing temperature of low temperature disperse dip dyeing of PLA/cellulosic blended fabrics is usually above 110℃ .The dyeing temperature of PLA can be reduced to below 100℃ by the development of environment-friendly carriers,and there is no special requirement for disperse dyes.The disperse dyes commonly used in pad dyeing can improve the dyeing depth of PLA fiber,reduce the strength loss of PLA fiber fabrics and improve the fastness of fabrics.
