摘　　要：为解决PLA/棉/PTT 3组分包芯纱针织物采用二浴法工艺染色时出现的加工耗时较长和生产效率较低的问题,研究了PLA/棉/PTT 3组分包芯纱针织物的节能、环保低温一浴染色新工艺。由于PLA不耐碱,出于对其组分性能的保护,选用中性条件下固色的Argazol N系列活性染料染棉组分;同时,选用对棉组分沾色相对较轻的中温型分散染料染PLA、PTT组分;染色处方中加入2.5 g/L扩散剂NNO,可实现很好的防沾色效果。通过对Argazol N染料固色温度的研究和环保载体CWP-910的使用,PLA/棉/PTT 3组分包芯纱针织物可实现在90℃低温条件下染色。研究表明,染色过程保温30 min,既可保证较高的上染率,同时PLA、PTT组分又有很好的同色性。Two-bath process dyeing of PLA /cotton /PTT core-spun yarn knitted fabric is time-consuming and low efficiency.A new low temperature one bath dyeing of PLA /cotton /PTT core-spun yarn knitted fabric is investigated,which is energy-saving and environmentally-friendly.The PLA component is not alkali-resistant.For protecting it,Argazol N reactive dyes which can be fixed under neutral condition were chosen to dye the cotton component.At the same time,the mild temperature disperse dyes which can decrease color contamination were chosen to dye PLA and PTT components.Dyeing prescription by addition of dispersing agent NNO 2.5 g / L into the dyeing recipe can achieve good anti-staining effect.Through investigation of fixing temperature of Argazol N dyes and applying environmentally-friendly carrier CWP-910,PLA /cotton /PTT core-spun yarn knitted fabric can be dyed at low temperature 90 ℃.Holding the temperature for 30 min during dyeing can ensure higher uptaking rate and union dyeing of PLA and PTT components.
