摘　　要：为提高活性染料传统轧-蒸染色的固色率和染深性,将真空脱水技术引入棉织物的活性染料轧-蒸染色过程。研究了棉织物含水率、汽蒸时间和碳酸钠用量对活性金黄SRE湿蒸染色的影响,并比较了活性金黄SRE采用浸轧-真空脱水-湿蒸(P-Vac-S)工艺与传统浸轧-湿蒸(P-S)工艺染色棉织物的染深性和耐摩擦色牢度。结果表明;浸轧含25 g/L活性金黄SRE染液的棉织物,将其含水率真空脱水至20%~30%,再进行湿蒸,棉织物的上染率(K/S值)和染料固色率相对较高;含水率为(25±2)%的棉织物湿蒸染色的适宜汽蒸时间和碳酸钠质量浓度分别为5 min和25 g/L;采用活性金黄SRE经P-Vac-S工艺染色棉织物的K/S值比采用P-S工艺染色的K/S值高15%~30%,但是经前者染色棉织物的耐摩擦色牢度比后者略差。In order to enhance the fixation rate and color build-up property of reactive dyes in the conventional pad-steam（ P-S） dyeing process,a vacuum-dewatering procedure was incorporated. Factors influencing the wet-steaming dyeing of reactive golden yellow SRE,such as the water content of the padded cotton fabric,the steaming time and sodium carbonate dosage were investigated. The color buildup property and rubbing fastness of the cotton fabrics dyed using the pad vacuum-dewatering steam（ PVac-S） process and the P-S process were compared as well. The results show that cotton fabrics padded with 25 g/L dye liquor exhibit higher K/S value and dye fixation rate by reducing the fabric water content to 20%-30% by vacuum-dewatering prior to the steaming stage. The steaming time of 5 min and sodium carbonate concentration of 25 g/L were appropriate for dyeing of padded cotton fabrics with（ 25 ± 2） %water content. The K/S value of the cotton fabric is improved by 15%-30% when dyed by the P-Vac-S process,compared with that by the P-S process,however,the rubbing fastness of the cotton fabric obtained by the former process was a bit poorer than that by the later process.
