| | The dyeing properties of reactive disperse dyes containing β-sulfatoeth- ylsulfone groups on nylon have been studied. A batchful dyeing of these dyes on the fibre shows they are brilliant in shades, good fastness of light and wet treatments, particularly in its covering properties. | | 研究了含β-羟乙基砜硫酸酯基的活性分散染料在锦纶上的染色性能。经生 产中放样证明:这类染料具有色泽鲜艳、盖染性优异以及良好的耐光、耐湿处 理牢度等优点。 | | 文摘来源 | | 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. | | 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。 | | 文摘来源 | | This paper deals with the characterization of the oriented state both in the sheathand in the core of the polyamide 6-polyethylene terephthalate bicomponent fiberunder the condition that the individual components need not be separated inadvance.This can be done by measuring simultaneously the apparent acousticorientation factor of the bicomponent fiber,the birefringences and X-ray orientationindices of polyamide sheath and polyethylene terephthalate core.From the experi-mental results obtaied it may be seen... | | 本工作的目的在于不进行组分分离、不破坏复合丝结构的条件下,逐级测定和研究锦-涤纶皮芯型复合丝的取向态结构及其与工艺过程的关系。首先用声速法测定了复合丝的表观声学取向因素,而后用双折射法分别测定锦纶皮层和涤纶芯层的双折射率,最后用X-光法测定了复合丝中锦纶组分与涤纶组分晶区的取向指数。研究结果表明,在拉伸过程中锦纶皮层取向态的变化规律与纯锦纶相同,而涤纶芯层又与纯涤纶相同。拉伸温度对皮芯层取向态结构的影响也同样如此。这就从侧面证实了上述三个测试方法的合理性。这些方法的建立对其它品种复合丝的研究也具有一定参考价值。 | | 文摘来源 | |   | | << 更多相关文摘 |
