Description

一种通用型数码喷墨印花打底浆及其制备方法
技术领域
本发明涉及染整技术领域，更具体地说，涉及一种通用型数码喷墨印花打底浆及其制备方法。
背景技术
市场上现有的大多数数码印花上浆处理剂都是专门性的，针对于不同的染料和纺织材质，有不同的数码印花上浆处理剂，这样容易造成工厂使用不方便，需要备用很多品种的数码印花上浆处理剂；另外目前市场上几乎所有的数码印花上浆处理剂，都是拿传统的印花糊粉来替代，使用时需要化料，搅拌12小时甚至更长的时间，给工厂使用带来极大不便；用传统印花糊粉开释替代数码上浆处理剂仅仅只能满足现代数码印花技术的基本要求，但不能满足数码印花高质量的要求。如得色浅、容易渗化造成清晰度很差、印制后的牢度很差等；目前市场上的数码上浆剂基本上都是传统的印花糊料改过来的，使用时，粘度不好掌控，慢慢变大，流动性不好，容易形成浆斑。
发明内容
有鉴于此，本发明提供了一种通用型数码喷墨印花打底浆及其制备方法，以解决现有技术中数码印花上浆处理剂因流动性差而形成浆斑的缺陷。
一种通用型数码喷墨印花打底浆，其原料包括有去离子水，还包括有2-丙烯酰氨基-2-甲基丙磺酸、丙烯酸、丙烯酰胺、氢氧化钠以及引发剂；其中，按重量比，所述2-丙烯酰氨基-2-甲基丙磺酸的占比为15％-30％，所述丙烯酸的占比为1％-5％，所述丙烯酰胺的占比为1％-5％，所述氢氧化钠的占比为3％-10％，所述引发剂的占比为0.1％-10％，余量为去离子水。
作为本发明的优选方案，按重量比，所述2-丙烯酰氨基-2-甲基丙磺酸的占比为20％-25％，所述丙烯酸的占比为2％-4％，所述丙烯酰胺的占比为2％-4％，所述氢氧化钠的占比为6％-9％，所述引发剂的占比为0.5％-5％，余量为去离子水。
作为本发明的优选方案，所述引发剂为过硫酸铵水溶液，其原料包括有过硫酸铵和去离子水。
作为本发明的优选方案，按重量比，所述2-丙烯酰氨基-2-甲基丙磺酸的占比为20％，所述丙烯酸的占比为2％，所述丙烯酰胺的占比为2％，所述氢氧化钠的占比为6.5％，所述引发剂的占比为2.5％，余量为去离子水。按重量比，所述引发剂原料包括有0.5％的过硫酸铵和2％的去离子水。
作为本发明的优选方案，按重量比，所述2-丙烯酰氨基-2-甲基丙磺酸的占比为22.5％，所述丙烯酸的占比为3％，所述丙烯酰胺的占比为3％，所述氢氧化钠的占比为7.5％，所述引发剂的占比为2.05％，余量为去离子水。按重量比，所述引发剂原料包括有0.75％的过硫酸铵和1.3％的去离子水。
作为本发明的优选方案，按重量比，所述2-丙烯酰氨基-2-甲基丙磺酸的占比为25％，所述丙烯酸的占比为4％，所述丙烯酰胺的占比为4％，所述氢氧化钠的占比为9％，所述引发剂的占比为2.3％，余量为去离子水。按重量比，所述引发剂原料包括有1％的过硫酸铵和1.3％的去离子水。
一种通用型数码喷墨印花打底浆的制备方法，其特征在于，用于制备所述的通用型数码喷墨印花打底浆，包括以下步骤：
S1、依次把2-丙烯酰氨基-2-甲基丙磺酸、丙烯酸和丙烯酰胺单体加入烧瓶中，再加入去离子水，搅拌溶解；
S2、往烧瓶中加入NaOH中和使得pH调为7.0；
S3、往烧瓶通氮气保护，并将烧瓶内溶液加热升温到75℃；
S4、加入引发剂，降温并保持烧瓶内溶液温度维持在75℃；
S5、加热保温反应之后，将产物冷却至室温，得到浅黄色透明粘稠液体的通用型数码喷墨印花打底浆。
从上述的技术方案可以看出，本发明的有益效果为：本发明所制备的通用型数码喷墨印花打底浆，是一种合成的高分子化合物，粘度适中，流动性好，在织物上上浆均匀，水溶性佳，容易在喷墨织物的后洗水过程中容易脱除，不影响最终成品的手感；在织物上浆过程中，始终粘度保持一致，粘度容易控制，对上浆工艺压辊的压力要求不高，不会出现浆斑，影响后续喷墨印花成品质量，能满足不同纤维材质的数码印花上浆剂要求；增深效果比较好，印制出来的布面效果清晰、鲜艳度高，从而解决了现有技术中数码印花上浆处理剂因流动性差而形成浆斑的缺陷，得到一种低成本和高性能的通用型数码喷墨印花打底浆。

使用前先把实施例2、尿素、硫酸铵、水搅拌均匀，再添加柠檬酸制成数码印花浆料，织物上浆(80-90％轧液率)→烘干(温度80℃，时间10min)→喷印→汽蒸(蒸化温度102℃，时间20min)→冷水淋洗(5-10min)→皂洗(防沾皂洗剂2g/L，碳酸钠1g/L，室温，时间10min)→皂洗(皂片2g/L，温度40℃，时间12min)→皂洗(防沾皂洗剂2g/L，碳酸钠1g/L，温度45℃，碳酸钠1g/L，时间10min)→定型烘干→成品检测

效果测试：经优化工艺上浆后，尼纶/氨纶织物数码印花表观得色量K/S值大于市场传统的天然植物胶改性的数码印花上浆剂，渗化程度R在45-55之间，渗化度较低，印制花纹比较精细，各项色牢度均达到4级以上，也就是说，本实施例1所制备的数码印花打底浆对于尼纶/氨纶织物数码印花的印花精细度是高于传统的瓜儿胶改性浆对于尼纶/氨纶织物数码印花的印花精细度，且本实施例1所制备的数码印花打底浆对于尼纶/氨纶织物数码印花的印花效果是高于传统的瓜儿胶改性浆对于尼纶/氨纶织物数码印花的印花效果的。
实施例6
织物涤纶增白织物(220g/m2)
试剂分散染料墨水(红、黄、蓝)，数码印花打底浆实施例3，尿素，柠檬酸，酸性还原清洗剂，醋酸，罗望子果改性浆
测试方法
表观得色量K/S测试：在Datacolor 800测色配色仪上采用D65光源和10。视场测定。测5个不同的位置，取平均值。
墨水在织物上的渗化程度R测试：R＝(S-S′)/S*100％,其中S′表示设计印花图案的面积,S表示喷印完成后图案的实际面积,渗化程度R值越小，印花精细度越高,印花效果越好。
耐洗色牢度:参照GB/T3921.1-1997《纺织品色牢度试验耐洗色牢度》测定。
耐摩擦色牢度:参照GB/T3920-1997《纺织品色牢度试验耐摩擦色牢度》测定。

使用前先把实施例3、尿素、水搅拌均匀，再添加柠檬酸制成数码印花浆料。织物上浆(80-90％轧液率)→烘干(100℃)→熨平织物(120℃)→喷印→纸张热转移热压织物(220℃，15秒)→冷水洗→热水洗一皂洗(酸性还原清洗剂2g/L,醋酸0.5g/L,85℃X20min)→冷水洗→定型烘干→成品检测

效果测试：经优化工艺上浆后，涤纶织物数码印花织物表观得色量K/S值大于市场传统的天然植物胶改性的数码印花上浆剂，渗化程度R在45-55之间，渗化度较低，印制花纹比较精细，各项色牢度均达到4级以上，也就是说，本实施例1所制备的数码印花打底浆对于涤纶织物数码印花的印花精细度是高于传统的罗望子果改性浆对于涤纶织物数码印花的印花精细度，且本实施例1所制备的数码印花打底浆对于涤纶织物数码印花的印花效果是高于传统的罗望子果改性浆对于涤纶织物数码印花的印花效果的。
从上述实施例可以看出，现有数码上浆预处理剂都是用传统的植物胶化学改性品，使用前需要化成粘稠液体，才能使用，天然化学改性植物胶很难化料，需要搅拌24小时，静止放置24小时，才能上机使用，所以给工厂生产带来十分不变；本发明所得的产品本身就是粘稠液体，可以直接使用，给工厂提高生产效率，节约成本(2)市场上传统的天然植物胶化学改性产品，由于原料产地、自然生长环境不一样，造成原料批次质量不稳定，从而造成化学改性后的产品质量不稳定，粘度和流动性变化很大，影响最终数码印花产品的质量；本发明所得的产品，是通过化学聚合得到的高分子粘稠液体，产品粘度和流变性能容易控制，质量稳定，容易控制数码印花产品质量(3)本发明所得产品可以适用于不同纤维制成的面料，预处理在织物上，喷墨时不容易渗化，得色深，花纹精致清晰，容易洗水去除手感好；市场上植物胶改性的数码印花上浆预处理剂，难于洗水去除，手感差，得色浅，容易渗化，不适合印制精细花纹。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分相互参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
