Description

一种超临界CO2染色专用偶氮型活性分散染料
技术领域
本发明涉及偶氮型染料,尤其涉及一种超临界CO2染色专用偶氮型活性分散染料。
背景技术
超临界CO2无水染色技术由Schonmeyer等人在1988年提出,随后经Knittel进一步发展(参考文献:超临界流体染色技术的过去、现在和将来(一)[J].印染,2003,29(3):42-45;在超临界二氧化碳中活性分散染料对天然纤维的染色[J].国外纺织技术:纺织针织服装化纤染整,2003,9:22-27.)。目前,合成纤维(如涤纶、尼龙等)的超临界CO2流体染色技术相对较为成熟,部分适用染料可在现有的分散染料中进行筛选,牢度性能优良。
然而,在天然纤维的超临界CO2无水染色方面存在的问题较多,适用的染料较少。这主要是因为天然纤维为极性纤维,在非极性的CO2中无法打开足够的氢键使染料扩散进入纤维内部,或染料对纤维的亲和力小,无法上染纤维。为此,人们也作了许多努力,试图改变这一现状。例如:对天然纤维进行溶胀剂和交联剂浸渍处理,对纤维进行改性,以及使用共溶剂等。但这些方法需要对纤维进行预处理,在染色过程中需添加相当高浓度的改性处理剂以获得较高的染色深度,有时纤维在染后还需进行清洗,从而失去了超临界CO2染色的独特优势(参考文献:超临界流体染色技术的过去、现在和将来(二)[J].印染,2003,4:37-45;Applicationofsupercriticalcarbondioxideinfinishingprocesses[J].JournaloftheTextileinstitute,1993,84(4):534-552;Dyeingofcottoninsupercriticalcarbondioxide[J].DyesandPigments,1998,39(4):335-340;Mordantdyeingofwoolbysupercriticalprocessing[J].TheJournalofSupercriticalFluids,2000,18(3):247-252;Dyeingwoolwithoutwater-possibilitiesandlimitsofsupercriticalCO2[C]//4thInternationalSymposiumExtractionforSamplePreparation-SFE-(X)SE-SPME-Bookofabstracts.1999:29-30;Dyeingofcottonfiberswithdispersedyesinsupercriticalcarbondioxide[J].DyesandPigments,1998,36(2):103-110;Thedyeingofnaturalfiberswithreactivedispersedyesinsupercriticalcarbondioxide[J].DyesandPigments,2003,56(1):27-35.)。
活性分散染料以分散染料为母体,并带有活性基,可以与天然纤维大分子上的官能团反应,从而实现共价键结合,其湿处理牢度优良。此外,偶氮型活性分散染料,其母体结构通常发色强度高,色谱齐全,色泽艳丽,且合成方法较为成熟,生产成本较低,可为解决超临界CO2流体中天然纤维的染色难题提供较好的途径。
发明内容
为解决上述技术问题,本发明的目的是提供一种超临界CO2染色专用偶氮型活性分散染料,该染料反应活性较高,染色温度低,适用于天然纤维的超临界CO2流体染色。
