摘　　要：采用3只L型活性染料安诺素黄棕L-F,安诺素红L-S,安诺素藏青L-3G用于羊毛染色,探讨染色方法、碱剂用量、氯化钠用量、固色温度和时间对染色K/S值的影响,测试了染色牢度。研究结果表明,采用先酸后碱法用于羊毛的染色,染色可获得较高的表观色深值,当染料用量为2%（owf）时,最佳染色工艺为：染色pH值4,纯碱1 g/L,氯化钠30 g/L,固色温度90℃,固色时间30 min左右,染色的耐洗和耐摩擦牢度均在3～4级以上。Three L type reactive dyes namely ANOZOL yellow L-F,red L-S and blue L-3G were used to dyeing of wool fiber. The influence of dyeing method,dosage of alkali and sodium chloride,dyeing temperature and time on K /S value of wool fabrics was investigated. The dyeing fastness of dyed fiber was also tested. It was found that use the dyeing method of first dyeing at acid condition then fixing at alkali condition,the dyed fiber obtained high K /S value. The results showed that the optimal process was reactive dyes 2%（ owf）,pH value 4,sodium carbonate 1 g /L,sodium chloride 30 g /L,fixing at90 ℃ for about 30 min. The fastness of dyed fiber was all above of 3 ～ 4 grade.
