摘　　要：为了推进低温活性染料在生产中的应用，研究了染色工艺对L型活性染料上染百分率的影响与L型活性染料的染色性能．结果表明，当L型活性染料质量分数为3％时，用纯碱与烧碱的混合碱为固色碱剂。最佳染色和固色温度为40℃、最佳食盐用量为50g/L、最佳纯碱用量为5—6g／L、最佳固色时间为70min，L型活性染料对纤维素纤维的亲和力及直接性低、反应速率大、染料之间相容性好．In order to promote the application of low temperature reactive dyes in production, the effect of dyeing process on the dye uptake of type L reactive dyes and dyeing performance of type L reactive dyes were investigated. The results showed that the optimal conditions were sodium chloride 50 g/L, sodium carbonate 5 -6 g/L, dyeing and fixing at 40 ℃ , and fixing for 70 min with L type reactive dye 3% , blend of sodium carbonate and sodium hydroxide as fixing alkali agent. The affinity and substantivity of type L reactive dye with cellulose fibers are low, while reaction rate is high, and compatibility is good between dyes.
