Description
技术领域
本发明涉及一种数码印花分散墨水及其制备方法和应用。
背景技术
近年来，时尚行业的高速发展使得纺织品印花行业面临着前所未有的变革压力，要求对市场快速响应、降低滞销产品及压低库存。同时，全社会对于环保的重视，也对纺织品印花行业的营运提出了更多的要求。伴随着科技的发展，数码印花行业应运而生。使用喷墨打印技术，结合喷墨设备专用的水性分散墨水、活性墨水、酸性墨水或者涂料墨水，可以实现纺织品印花的即时设计、生产，大幅降低印花过程产生的污染。
对于日益增加的工业级应用设备，由于喷头的改进，输出速度更快、精度更高，对于墨水的要求也有所不同。为保证高速打印下墨水的供应稳定，工业级喷头要求墨水粘度更高。然而现有的数码印花分散墨水在印花输出后干燥速度过慢，对于生产速度有显著影响，并且对于节能也有负面影响。汉生胶、卡波普等增稠剂，使用在喷墨墨水中，产生较明显的触变性，喷墨墨水希望墨水尽量接近于牛顿流体，汉生胶、卡波普在这方面也存在缺陷；另外，此类胶体，仅微量的添加，就已对粘度产生巨大影响，对于日常生产管理难度高。因此，本领域亟需研究新的具有合适粘度的数码印花分散墨水。
发明内容
本发明的目的是解决本领域缺乏一种具有合适的粘度的数码印花分散墨水的问题，进而提供了一种数码印花分散墨水及其制备方法和应用。本发明的数码印花分散墨水打印流畅，输出性能良好，且墨水的稳定性好，可长期放置，具有较高的工业推广应用价值。
本发明是通过以下技术方案来解决技术问题的。

由表3可见，相对于甘油，使用黄原胶制备的数码印花分散墨水的粘度更趋向于所期望的9.0mPa.s，且同套墨水粘度更一致。
效果实施例2
将本发明实施例1-4制备的数码印花分散墨水使用希望高科星光喷头测试机进行流畅性测试，连续打印5000张没有断线且无斜喷，流畅性良好。
而对比例1-5制备的数码印花分散墨水只能打印100张左右，由于漏墨严重，无法继续打印。
效果实施例3
将本发明实施例1-4制备的数码印花分散墨水进行1、3、5天60℃加热老化试验，墨水理化参数及性能没有发生明显改变。
应用实施例1-4
本申请应用实施例1-4为实施例1-4制备的数码印花分散墨水在工业数码纺织印花机(即希望高科星光喷头纺织印花机)中的应用。
具体的运用方式为：
(1)印花：将实施例1-4制备的数码印花分散墨水用于工业数码纺织印花机(即希望高科星光喷头纺织印花机)中直接喷墨印花；所述希望高科星光喷头纺织印花机的工作环境温度35℃、湿度20％；
(2)烘干：将打印好的织物与烘干机相连接，织物进入烘干机进行烘干；
(3)汽蒸固色：将烘干后的织物放入蒸箱进行汽蒸固色，汽蒸温度为160℃，汽蒸时间为12min。
