摘　　要：研究了低温型黑色活性染料的染色性能,探讨了各因素对染色效果的影响。结果表明,低温型黑色活性染料在中性盐浴的吸色阶段上色缓和,固着率较高;加入纯碱5g/L和液碱3g/L时,可获得最高得色量;在盐质量浓度20～70g/L范围内,得色深度对电解质的依附性较大;低温型黑色活性染料的上染率受浴比影响较大,染深性较好,铜离子对其影响较大,染色牢度总体较好。The dyeing properties of four L-type black reactive cold water dyes and factors influcing dyeing process are discussed. The dyeing rate of L-type black reactive dyes is lower and fixation rate is higher. Higher color yield is obtained when adding 5 g/L sodium carbonate and 3 g/L liqufd alkali, color depth is largely dependent on electrolyte with 20 - 70 g/L sodium sulfate. The influence of liquor ratio and metal ion Cu2＋ on dye-uptake is higher. The dye depth and color fastness is good.
