Abstract: Reactive disperse mono-azo dyes containing a β-hydroxy-ethyl sulfonyl sulfuric ester group in diazo component have been synthesized. The preparation of anthraquinone derivatives with the same reactive group are also studied. These dyes reacted chemically in weak alkali medium with synthetic polyamide fibres, such as nylon 66 and 6. The dyeing properties of both azo- and anthraquinone reactive disperse dyes on nylon 66 and 6 are being studied. The fastness properties of the dyed substrate are also examined. As expected, these dyes showed bright colours on various substrates, and the dyed fabrics have good fastness to light and wet treatment. The formation of the covalent bond between the reactive group and nylon fibre is proved and discussed. The reactive disperse dyes containing β-hydroxy-ethyl-sulfonyl-sul-furic ester group behaves the important characterictics of either acid reactive or disperse dyes for dyeing polyamide fibres. These dyes are suitable for dyeing various kinds of polyamide fibres as well as natural silk, tussah silk and crepe fabrics of silk with cellulose acetate and others.

摘要： 本文综合了应用于锦纶染色的弱酸性染料酸性浴上色的高竭染率,活性染料与纤维的共价键结合,分散染料在纤维上迁移、匀染、盖染性好等优点,提出一类含β-羟乙基砜硫酸酯基的活性分散染料。用分子较小的分散染料结构,以含β-羟乙基砜硫酸酯为活性基;在弱酸性浴中染色,再在弱碱性浴中与聚酰胺纤维反应成共价键结合。 合成了一系列偶氮型和蒽醌型染料。进行了合成工艺、对锦纶的染色性能以及染色锦纶的牢度等试验。并讨论了染料与聚酰胺纤维的结合 这类染料可用于锦纶66和锦纶6丝纺、弹力锦纶丝和针织品,还可用于桑丝、柞丝及其与人造丝的提花织物。这类染料在锦纶上色泽鲜艳,竭染率较高,益染性优良,耐晒、耐湿处理等牢度较好,适于各种锦纶织物的染色。这类活性分散染料,具有酸性染料、活性染料和分散染料染锦纶的主要特点。
