一种冷转移数码印花用油墨染料的制备方法与应用
技术领域
本发明涉及印染油墨,尤其涉及一种冷转移数码印花用油墨染料的制备方法与应用。
背景技术
面对国内印染业逐渐激烈的竞争,国外发达国家日益提高的环保壁垒,为了生存和发展,走高附加值、高科技含量的绿色印染之路是中国印染企业的必然选择。中国《纺织工业“十二五”发展规划与2020年强国纲要》指出:纺织行业需要加快产业结构和产品结构的升级调整,特别强调印染企业的清洁生产和环保技术。
转移印花在上世纪50年代左右发明的,即升华法,通过热量和压力,使得染料升华促使油墨层从转印纸上剥离,将转印纸上的图案转印到织物上,但是这种热转移印花技术指南使用在涤纶等化纤面料上,且在染料油墨的选择上局限性较大,很多染料在热转移时容易分解成致癌芳香胺物质,大大限制了热转移的发展,从而使得另一种印花工艺有了得以发展的空间,即冷转移印花,也称湿法转移印花,其对棉毛丝等天然纤维的印花具有显著的优势,但是将其应用到涤纶等面料中去时由于印花时无法达到一定的温度,现有的一些油墨染料的转移印花效果不佳,存在固色率较低,转移效率低的缺点。
发明内容
发明目的:为了解决现有技术所存在的问题,本发明提供了一种能有效提高化纤面料冷转移固色率和转移效率的冷转移数码印花用油墨染料的制备方法与应用。
技术方案:为达到上述目的,本发明提供了一种冷转移数码印花用油墨染料的制备方法,包括如下步骤:

更进一步的,所述界面引发剂为RMMA/PS核壳乳胶。
更为优选的,所述抗静电剂为亲水抗静电整理剂,与生物酶的相辅相成作用,进一步提高冷转移的转移效率。
更进一步的,所述亲水抗静电整理剂为聚丙烯酸酯类整理剂与柠檬酸钾质量比为6:1混合而成。
所述吸附剂为活性炭纤维;活性碳纤维固体表面原子呈不饱和结构,具有独特的表面化学性能,在一定的引发条件下会产生羧基、酚基、醌基等含氧基团,有效增加活性染料的吸附力和转移效率。
