淡水是一种日益稀缺的资源，广泛用于纺织品湿加工。在寻求确定替代低淡水使用染色技术，本研究探讨了潜在的使用海水（SEAW）作为染色介质的羊毛染色使用一系列活性染料。最初，羊毛织物在模拟海水（SSW）中的染色行为进行了比较，从蒸馏水（DW）使用-溴丙烯酰胺基Lanasol染料和硫酸根合乙基砜基Remazol染料的常规染色。这些初步研究表明，基于对染料吸尽性、染料固定性、颜色产率和匀染性的评估，在SSW培养基中可以实现相当的着色。随后使用Lanasol和Remazol活性染料对羊毛进行的染色研究证实，基于染料吸尽率、染料固色率、颜色收率和匀染性，可以实现可比的着色，突出了用海水替代淡水作为染色介质的可能性。
Freshwater is an increasingly scarce resource that is extensively used in textile wet-processing. In seeking to identify alternative low freshwater-usage coloration technology, this study examined the potential use of seawater (SEAW) as the dyeing medium for wool coloration using a range of reactive dyes. Initially, the dyeing behaviour of the wool fabric in simulated seawater (SSW) was compared with conventional dyeing from distilled water (DW) using -bromoacrylamide-based Lanasol dyes and sulphatoethyl sulphone-based Remazol dyes. These preliminary studies demonstrated that comparable coloration could be achieved in the SSW medium based on an assessment of the dye exhaustion, dye fixation, colour yield and levelness. Subsequent dyeing studies of wool using Mauritian seawater with both the Lanasol and Remazol reactive dyes confirmed that, based on the dye exhaustion, dye fixation, colour yield and levelness, comparable coloration could be achieved, highlighting the possibility of substituting freshwater with seawater as the dyeing medium.
