摘　　要：为解决在传统轧-蒸(P-S)染色工艺中因轧余率高、湿织物升温缓慢而导致的活性染料水解的严重问题,提出了在汽蒸前增加真空脱水工序的棉织物浸轧-真空脱水-湿蒸固色工艺(以下称作低含水率-湿蒸(L-W-S)染色工艺)。以活性蓝19为例,研究了织物含水率、汽蒸时间和Na2CO3质量浓度对棉织物低含水率-湿蒸染色的影响,并对L-W-S工艺与传统轧-(烘)-蒸(P-(D)-S)工艺染色棉织物的表观色深(K/S值)和染料固色率进行了比较。结果表明,不同染色深度时,活性蓝19采用L-W-S工艺上染试样的K/S值和固色率始终高于经传统P-(D)-S工艺上染试样,可为提高活性染料轧-蒸染色工艺的固色效率提供有效途径。In order to reduce the serious reactive dye hydrolysis ascribed to high pick-up and slowly heating of the wet fabric in the conventional pad-steam （P-S） dyeing process, a vacuum-dehydration procedure was employed for the padded cotton fabric prior to steaming （low-water content-wet steaming （L-W-S） dyeing process）. Reactive blue 19 was adopted as an example to investigate the influence of fabric water content, steaming time and Na2CO3 concentration on the steaming fixation of padded fabric with low water content. Comparison of the color strength （K/S value） and dye fixation rate （F） of the cotton fabrics dyed with the L-W-S dyeing process and the conventional pad-（dry）-steam [ P-（D）-S ] dyeing process was made. The results show that both K/S value and F of the dyed cotton fabric obtained from the former process are higher than those from the later process. Incorporating vacuum-dehydration procedure in the P-S dyeing process offers a potential way to improve reactive dye fixation.
