莫代尔氨纶混纺针织物的染整工艺

Dyeing technology of the Modal/polyurethane blended knitted fabric

为解决莫代尔氨纶混纺针织物在活性染料染色时,因对染化料较敏感,而在染整加工过程中易产生毛羽、擦伤、折痕等疵点问题,根据染整工艺流程,重点介绍了该织物染整工序中预定形、前处理、染色、柔软整理等工序的工艺处方和条件、工艺曲线及注意事项,得出在各个工序中要选择合适的助剂及加工工艺,是保证莫代尔氨纶混纺针织物较少疵点,提高质量的关键。

The Modal/polyurethane blended knitted fabric is sensitive to dyes and other chemicals,and thus the hairiness,scratching and rig mark are easily to occur in the dyeing and finishing process.According to the dyeing and finishing flow,this paper mainly introduces the technological plan,conditions,curves and precautions of pre-setting,pre-treatment,dyeing,softening finishing,and determines the appropriate auxiliaries and processes in different working procedures,which are keys to reduce defects and improve quality.
