摘　　要：选用Lanasol染料对牛奶蛋白纤维进行染色,通过对电解质及固色碱的复配,探讨了牛奶蛋白纤维低盐低碱染色的可行性,并优化了染色工艺。研究表明,采用10 g/L复配电解质Na2SO4/K2SO4(质量分数比1∶1)和2 g/L复配固色碱剂NaOH/KOH/Na2CO3/K2CO3(质量分数比1∶1∶1∶1)染色的牛奶蛋白纤维,上染率和K/S值均与常规工艺相当,且减少了Na2SO4和Na2CO3的用量,纤维蛋白质损失少。Milk protein fiber was dyed with Lanasol dyes.Through combination of electrolytes and alkali,the possibility of milk protein fiber dyeing with low-salt and low-alkali was discussed,and the dyeing process was optimized.The study showed that the dye uptake and K/S value of the dyed milk protein fiber with lower dosages of Na2SO4 and Na2CO3 were comparable with those of conventional technology,under the condition of 10 g/L mixed electrolytes of Na 2SO 4/K2SO 4（mass fraction to 1∶1） and 2 g/L compound fixing alkali of NaOH/KOH/Na2CO3/K2CO3（mass fraction to 1∶1∶1∶1）.
