摘要
本文研究了靛蓝染料对棉织物染色中,还原剂保险粉、二氧化硫脲的应用。探讨了还原剂的用量,氢氧化钠的用量对染液还原电位以及染色后织物的K/S值、干摩擦和湿摩擦牢度的影响,得出靛蓝染料浓度为10g/L时,二氧化硫脲用量为7g/L,氢氧化钠10g/L时染色性能较好。
An investigation into the application of reducing agents sodium hydrosulfite and thiourea dioxide is made during dyeing of cotton fabric with indigo, the paper discusses the effects of the dosages of reducing agent and sodium hydroxide on the reduction potential of dye liquor and the K/S value, dry and wet rubbing colour fastness of the dyed fabric. And it is found that better dyeing result can be achieved when indigo concentration =10g/L (omf), thiourea dioxide =7g/L, sodium hydroxide =10g/L.
