Description
技术领域
本发明属于数码印花技术领域，尤其涉及一种适用于京瓷喷头的水性活性直喷印花墨水及其制备方法。
背景技术
活性数码印花，也称活性数码直喷印花或活性数码喷墨印花，即利用数码技术对各种棉布、丝绸、亚麻等天然纺织面料进行直接印花加工，其加工过程简单来说就是通过各种数字化手段，将图像输入到计算机，通过印花软件系统编辑处理后，形成所需要的图案，再由输出软件控制打印，将各种专用印花墨水直接喷印到各种织物上，然后经过102℃的蒸汽固色、脱浆褪浮色、后整理等处理，获得印有高精度图案的印花纺织品。
纺织品数码喷墨印花技术依靠其明显的绿色印花技术和独特的印花方式，已在全球逐步替代传统的纺织品印花技术。随着数码喷墨印花技术的持续发张，从Epson头写真机活性直喷也发展到工业机活性直喷，在全国环保力度进一步加强的背景下，全国印染行业水污染问题更为突出。因而更多印染企业选择更环保的活性数码印花，从而促进了活性数码直喷印花的发展。作为活性数码印花中不可缺少的、决定印花效果的关键因素的活性印花墨水液随之发展。活性印花墨水是纤维素纤维和蛋白纤维上常用着色剂，具有印花产品色牢度高、色谱齐全和色泽鲜艳等特点。随着活性数码印花技术的持续发展，特别是速度更快、效率更高、精度更高的京瓷活性数码直喷印花，市场对活性印花墨水的要求不断增大。而且，由于京瓷喷头具有高精度、高速度以及高喷射墨量的特点，其对于活性印花墨水有着更高的要求，特别是延长喷头寿命、拉丝情况、打印面料的透过性、打印流畅性等要求，需要低含盐量、高得色率、高色彩还原性的环保型活性染料。但是，目前市场上尚未有适用于京瓷喷头活性印花喷墨打印机的国产高性能京瓷水性活性直喷墨水。
发明内容
为了克服现有国内技术中存在的以上缺陷，本发明的目的是提供一种适用于京瓷喷头的水性活性直喷印花墨水及其制备方法。

(4)上述得到的混合物进行测试粘度与表面张力，粘度合格范围为5-6.5mpa.s，表面张力合格范围为30-40mN/cm，合格后在35℃下陈化48h，使墨水中成分完全溶解以及分散体系达到平衡，不溶类物质和不稳定胶体析出；陈化完成后用1um PP熔喷滤芯和0.2um聚乙烯砜折叠滤芯正压过滤第一遍去除大颗粒及树脂沉淀，再用0.2um聚乙烯砜折叠滤芯负压过滤第二遍以进一步去除较小沉淀和絮凝胶体，最后用0.2um pp滤膜负压过滤并使用PALL除泡囊除泡后。
以和实施例1相同的制备方法、不同的配方制备得到实施例2-8和对比例1-8的京瓷水性活性直喷印花墨水，具体配方分别如表1和表2所示。
性能测试
将过滤后的墨水在京瓷KJ4B-300DPI喷头上用专用波形文件和测试图片测试墨水性能，连续打印时间不少于2h，打印前后测试条无断线、斜喷及拉丝等情况；测试完后关闭散喷待机30min，再次打印测试，测试条完好；最后打印机进行保湿处理后关闭电源，保持墨盒负压不滴墨情况下，72h后开机，清洗喷头时无堵孔斜喷现象，墨水性能优异。实施例2-8和对比例1-8的墨水的性能测试结果分别见表1和表2。
通过实施例和对比例对照实验可以得出UREA和Dynol 607的加入有效地改善了流畅性和真丝打印双面透的性能；UREA的加入有吸潮保湿的性能也能改善喷头长时间保湿。
