Description
技术领域
本发明属于印染技术领域,具体涉及一种绒面毛织物数码印花浆料,还涉及上述的浆料的制备方法。
背景技术
传统的印染工业由于污染严重、生产周期长、工艺复杂、设备投资大而越来越不能满足当前消费者对纺织服装面料个性化、高档化以及保健、舒适、环保的要求,在这种情况下,数码印染技术应运而生,它具有低能耗、无浪费、颜色无限制、快反应、应用广等特点,从而能够适应个性化、小批量、快反应的市场需求。
数码印花技术发展迅速,与传统的印花方式相比,数码印花工艺清洁,生产过程灵活,可以进行远程定货,纳入供应链网络,是未来纺织品印花技术发展的方向。虽然数码喷墨印花的优势很明显,但是纺织品在数码印花过程中也存在许多缺陷。比如,存在成本高,上浆中的问题以及在染色后羊绒织品的色差问题和墨水堵塞喷头、漏点现象等问题。羊绒数码印花前处理中浆料的好坏直接影响印染的效果,而浆料各成分的配比和各自的作用又对浆料至关重要。但是现数码印花浆料配比使用在绒面织物上,不能够使织物表面的绒毛贴服在表面,打印时易出现沾色和发色不均的现象。
董利光等人在《毛纺科技》2009年12月第37卷第12期的《毛织物数码印花浆料及其工艺研究》一文中披露了如下的方案:药品:海藻酸钠、尿素、碳酸氢钠、元明粉、磷酸氢二钠均为分析纯;二氧化硫脲,高效渗透剂AB,活性染料墨水为工业用。得出如下的结论:①数码印花羊毛织物上浆处理采用配方:海藻酸钠用量2%(owp),尿素用量7%(owp),二氧化硫脲、碳酸氢钠质量比3:2,二氧化硫脲与碳酸氢钠总用量0.75%(owp),高效渗透剂AB用量1.0%(owp),元明粉用量1%(owp)。②经过实验选用的浆料配方上浆,使得羊毛数码印花产品获得了较高的K/S值、鲜艳的颜色、清晰的图案及较高的色牢度。可以用于羊毛织物数码印花产品的开发。
该方法中汽蒸温度为102℃,时间是60分钟。汽蒸时间过长,不仅会对织物的品质产生影响,而且耗能高。但是汽蒸时间过短,会导致色牢度等指标达不到要求。
因此,需要针对上述的数码喷墨印花的缺点,设计一种适用于绒面毛织物的印花浆料及浆料的配制方法,通过调整浆料及上浆工艺,达到减小能耗但是并不影响产品品质的目的。
发明内容
为了解决上述的技术问题,本发明提供了一种适于绒面毛织物的印花浆料,采用该浆料对织物处理,上浆后织物表面的绒毛贴服在表面,织物表面平整,打印时不会出现沾色现象;又能使数码印花纺织品得到优良的色牢度,同时保持织物的原始手感和风格。
本发明还提供了上述的浆料的制备方法,以及上述的绒面毛织物数码印花的方法。
本发明的绒面毛织物数码印花浆料,包括下述的原料:
亚硫酸钠、尿素、海藻酸钠、DGT–7、渗透剂、硫酸铵、冰醋酸、水。
海藻酸钠占原料总重量的3.5-4.5%。
海藻酸钠与DGT–7的重量份数比为1:1。
绒面毛织物数码印花浆料,包括下述重量份数的原料:
亚硫酸钠:4-9;尿素:8-12;海藻酸钠:2-6;DGT-7:2-6;
渗透剂:4-7;硫酸铵:2-5;冰醋酸:1-3;水:60-72。
绒面毛织物数码印花浆料,包括下述重量份数的原料:
亚硫酸钠:6;尿素:10;海藻酸钠:4;DGT-7:4;
渗透剂:5.5;硫酸铵:2.5;冰醋酸:2;水:66。
绒面毛织物数码印花的工艺,包括下述的步骤:
(1)配制浆料;
(2)在浆料中加入防染盐,搅拌均匀;
(3)上浆;数码印制:在印制过程中,先印制反面花型,彻底烘干,再印制正面;
(4)蒸化;
(5)水洗。
绒面毛织物数码印花的工艺,其特征在于,
加水:在打浆桶中加入所需的水量;
开搅拌机:搅拌机的桨叶置于浆桶中心,距桶底的高度为0.5-1倍桨叶的直径,开搅拌机,转速调至1440r/min;
加亚硫酸钠:当搅拌至桶内为均匀浆状体,无颗粒状物时,即缓慢向浆料漩涡中心加入所需的已溶解好的亚硫酸钠,继续搅拌均匀;
加尿素:待无不溶物时,缓慢向浆料漩涡中心加入所需尿素,继续搅拌;
加硫酸铵:放置,当浆料温度在50℃以下,缓慢向浆料漩涡中心加入所需的加硫酸铵,继续缓慢搅拌,确保浆料不发热,待其搅拌均匀,调浆完毕;
加糊料:加入DGT-7、海藻酸钠;控制搅拌机的转速为650-750r/min,缓慢向浆料漩涡中心加入所需的糊料粉状物,继续搅拌;
加其它助剂:待浆料完全搅拌均匀时,控制搅拌机的转速为650-750r/min,加入渗透剂和冰醋酸,再高速搅拌均匀,高速搅拌的转速>1500r/min;
静置:检查浆料无明显颗粒后,再放置2小时,使各组分混合均匀。
绒面毛织物数码印花的工艺,其特征在于,
防染盐为防染盐S、防染盐K中的任一种,防染盐的加入量占元明粉重量的20-30%。
数码印制过程中,保持室内温度为20-24℃,湿度为45-50%。
蒸化步骤中,抽出蒸罐中的废气,将蒸罐预热到70℃;再将印制完成后的面料或织物置于蒸车中,推入蒸车到蒸罐中,在95-100℃下蒸化25-35分钟;
水洗步骤中,冷水冲淋,加入防沾剂后用冷水清洗,50-60℃温水洗,皂洗,冷水洗净,采用柔软剂浸泡3-7分钟,晾干。
本发明的有益效果在于,采用本发明的浆料对绒面毛织物处理,上浆后织物表面的绒毛贴服在表面,织物表面平整。打印时不会出现沾色现象。
而且采用本发明的浆料处理后的织物抱水性、匀染性好,对染料上染影响小,可得到既精细又均匀艳丽的印花效果。
浆中所有添加助剂,均需符合生态纺织品的要求,固含量低,易脱糊洗净。既能减轻环境工作压力,又能使数码印花纺织品得到优良的色牢度,同时保持织物的原始手感和风格。

测试指标:
(1)表观色深度量/S值
将打印色块的布折成4层,使用ORINTEX测色配色***,测定染色织物的K,S值,测定3个不同的位置,取平均值。本文实验采用色卡C、M、Y、K,印花后K/S值的加和作为实验K/S值的评判标准,并且以K/S值作为印花效果的主要评价指标,即K/S值越高,印花效果越好。
(2)印花颜色鲜艳度
将打印色块的布折成4层放到ORINTEX测色配色***上,然后测定染色织物的C值,为了读数准确测定3个不同的位置,取平均值。
具体的方法参照《颜色科学与计算机测色配色实用技术》薛朝华北京:化学T业出版社,2004,62—63。
(3)印花后织物未印花部分的白度
将织物未印花部分折叠4层置于白度仪,不同位置上测3次,取测量的平均值作为试样的白度值。
(4)印花后织物的色牢度
耐摩擦色牢度参照GB/T 3920-1997-纺织品色牢度试验耐摩擦色牢度》测定。耐洗色牢度参照GB/T 3921.1—1997《纺织品色牢度试验耐洗色牢度:试验1》。
