摘要
含β-牛磺基乙基砜和一氯均三嗪双活性基活性染料,是一种新型丝绸用染料,这类染料在丝绸上有很好的染色性能,匀染性好,各项色牢度优异,且染色工艺简单,染色重现性好。在色度1%、浴比为1:40的标准染色条件下,温度为50℃时,放入真丝织物,以1℃/min的升温速度升温至95℃,保温40min,用含3g/l标准合成洗涤剂溶液沸煮15min,清水漂洗干净,晾干。吸色率:95.6%~98.6%;固色率:88.5%~97.4%;当色度从0升至5%时,Integ值可达11~68.1;随电解质用量上升,Integ值增加,以40g/l~60g/l为宜;在pH为6.5~7时,染色效果最好;而对温度、染色时间和浴比的变化不敏感。所有染料的色牢度均在4~5之间,有三个品种的耐光牢度达到了6~7级。
Some novel reactive dyes containing 2-{{2-(4-Aminobenzenenesulfonyl)-ethyl}-methylamino}ethane sulfonic acid and monochlorotriazine reactive groups were used for dyeing silk, these dyes had very good dyeing properties, especially good levelness, excellent color fastnesses, good reproductivity, and employed a simple dyeing process. Silk fabrics were dyed in dyeing bath containing 1% dyes with bath ratio of 1:40 at 50℃, heated to 95℃ by 1℃/min, and kept for 40min at 95℃, then boiled in a solution containing a surfactant 3g/l, rinsed with water and air dried. The dye uptake was 95.6~98.6%, fixation was 88.5~97.4%. When the concentration of dyes was increased to 5%, the integ value was 11-68.1%. With the increase of electrolyte, the integ, value increased, and the suitable dosage of electrolyte was 40-60g/l. The dyeing effects were the best at pH 6.5-7, and not sensitive to dyeing temperature, time and bath ratio. The color fastnesses of these dyes were 4-5, and three of these dyes had high lightfastness of 6-7.
