The Application of Dispersing Agent NNO in the Package Dyeing of P/C Yarn

扩散剂NNO是阴离子表面活性剂。外观为浅棕色粉末。易溶于水、无渗透性、不起沫。利用NNO的扩散性对涤棉筒子纱染色。使染色后的纱线得色均匀,克服了内外色差。节约了染料,降低了成本,简化了工艺。扩散剂NNO用量为1g/L。

Dispersing agent NNO, an impermeable and foamless powder with light brown colour, is an an-ionic surface active agent which is easy to solve in water. The package dyeing process in a quantity of 1g/L dispersing agent NNO for P/C yarn is introduced, with which the yarn is even dyed without inner-outer colour difference,chemicals are saved, technological process simplified and the dyeing cost decreased .
