摘　　要：采用AnozolL型活性染料对纯棉针织物进行低温染色，探讨了染色温度、碱剂种类、固色pH值、元明粉质量浓度和固色时间对K/S值的影响，得出的优化染色工艺为：染料2％（omf），纯碱5g／L，烧碱0．5—1．0g／L，元明粉4｜Dg／L，40℃固色90min。该系列染料提升性好，适宜染中深色；染色织物匀染性好，耐摩擦色牢度和耐皂洗色牢度均较高，具有显著的节能减排优势。Anozol L-type reactive dyes are applied to cotton knits dyeing at low temperature and the factors affecting the K/S values are discussed, including dyeing temperature, alkaline agent, fixing pH value, dosage of Na2SO4 and fixing time. The results show that the optimum dyeing process is L-type reactive dye 2% （omf）, Na2CO3 5 g/L, NaOH 0.5 - 1 g/L, Na2SO4 40 g/L, fixing at 40 ℃ for 90 min. Anozol L-type reactive dyes have good building up properties and levelness which are suitable for medium to dark shade dyeing, as well as good fastness to rubbing and soaping. L-type reactive dyes also have the advantage of energy saving and emission reduction.
