| 摘 要： | 利用某些活性染料与乙烯砜活性染料的耐Na2SO3及其衍生物的差异,以达到活性防染活性的目的.通过筛选部分耐Na2SO3的活性染料,发现一氯均三嗪类活性染料效果较好;推荐以Resistol HWS替代Na2SO3时适用的防印活性染料品种,介绍了以Remazol Salt FD为碱剂的罩印工艺,以及日本专用拔染剂Emvatex DK-TN和助拔剂的性能及其工艺;给出了抑制乙烯砜活性染料"失风"的几种措施.

| Abstract: | Owing to different resistance to sodium sulfate and its derivations of some reactive dyestuffs and vinyl sulfone reactive dyestuffs, reactive discharge or resist printing process is carried out. Suitable reactive dyestuffs are screened, it is found that monochloro-s-triazine dyes have good resistance to sodium sulfite. Because sodium sulfite is not stable, various substi- tutes in market are recommended, such as resist printing with Resistol HWS to replace sodium sulfite, over printing with Rern- azol Salt FD as alkaline agent, as well as discharge agent Emvatex DK-TN and discharge promoter. Measures to prevent deactivation of vinyl sulfone reactive dyestuffs are put forward. |
