Definitions

  • the invention relates to a fabric pile dyeing technology, in particular to the preparation of functional cotton fabrics with dopamine and reactive dyes.
  • Reactive dyes are commonly used dyes for cotton fibers. They are mostly used in solution phase dyeing, pad dyeing, and continuous pad and steam dyeing (such as hot-melt and steam continuous dyeing of polyester-cotton fabrics). There are active groups in the structure of reactive dyes that can react with cotton fibers. The active groups can form covalent bonds with the hydroxyl groups on cotton fibers, and can also undergo hydrolysis reactions with water to lose the activity of the dye.
  • Pad-batch dyeing of reactive dyes is to pad cotton fibers with reactive dye dyeing solution, and at the same time, roll padded cotton fabrics into rolls, and stack them at room temperature for a certain period of time to complete the covalent bonding of reactive dyes and cotton fibers; and then pass Conventional soaping and washing post-dyeing processes are used to remove impurities on the fiber, such as unfixed dyes, hydrolyzed dyes and dyeing auxiliaries.
  • the biggest feature of pad-batch dyeing with reactive dyes is that dyeing and fixing can save a lot of energy consumption. However, reactive dyes with strong activity must be selected before they can be used. Otherwise, the fixation rate of reactive dyes will be significantly reduced and a large amount of dyes will be wasted. This limits the majority of The application of reactive dyes, therefore, the development of lower temperature hot pile dyeing technology with reactive dyes meets the requirements of energy saving and emission reduction.
  • Dopamine is the amino catechol. In recent decades, dopamine and its analogs have been widely used in the field of materials. Dopamine can undergo oxidative self-polymerization under certain conditions. The self-polymerization of dopamine can be used to modify the surface coating of materials to prepare functional materials. Because oxidative self-polymerization is the simplest and most efficient, dopamine has been extensively studied in the textile field to prepare textiles with hydrophilicity, UV resistance, and antibacterial properties.
  • polydopamine is difficult to control to a fixed color, which makes the modification process difficult to control and the color reproducibility is poor.
  • Dopamine is easily adsorbed on the surface of textile fibers and generates polydopamine through oxidation and self-polymerization.
  • polydopamine is formed into a porous loose structure and cannot form a uniform film-like structure on the fiber surface. Therefore, it cannot be used for textile clothing.

  • the invention uses dopamine and reactive dyes to process cotton fibers in the same bath to achieve oxidative self-polymerization of dopamine and fixation of reactive dyes to fibers, which can not only enrich the color of cotton fibers, but also utilize the functionality of polydopamine; and can form polydopamine on textile fibers.
  • the dense film-like polydopamine can meet the requirements for color fastness (such as rubbing and home washing) when using textile clothing.
  • the present invention adopts a pad-dying method in which dopamine and reactive dyes are bathed in the same bath, and is combined with padded cotton fabrics to be stacked in rolls. The polydopamine penetrates into the yarn and the fiber to modify the fiber with polydopamine.
  • the stacking conditions are further disclosed.
  • the swelling effect on cotton fibers is conducive to the oxidation and self-polymerization of dopamine to form dense film-like polydopamine.
  • the selection range of reactive dyes is also wider, and its dyeing performance is better than the existing reactive dye padding process.

Description

一种基于多巴胺和活性染料的棉织物轧堆染色方法 技术领域
本发明涉及一种织物堆染色技术，具体涉及多巴胺和活性染料制备功能性棉织物。
 背景技术
活性染料是棉纤维常用的染料，多采用溶液相染色、轧堆染色、连续轧染汽蒸染色（如涤棉织物的热溶和汽蒸连续染色）。活性染料结构上存在能与棉纤维反应的活性基，活性基能与棉纤维上的羟基生成共价键，也能与水发生水解反应而失去染料的活性。活性染料的轧堆染色是将棉纤维浸轧活性染料染色液，同时将浸轧棉织物卷装成卷，在室温下堆置一定时间，完成活性染料与棉纤维的共价键结合；再通过常规的皂洗和水洗的染色后处理工序来去除纤维上的杂质，如未固着染料、水解染料及染色助剂等。活性染料轧堆染色的最大特点是染色和固着能节约大量的能耗，但必须要选择活性强的活性染料才能使用，否则会明显降低活性染料的固着率，浪费大量的染料，这限制了多数活性染料的应用，因此开发活性染料的较低温度热堆染色技术符合节能减排和节能降的要求。
随着休闲运动面料的快速发展，制备功能性棉织物是今后发展的重要方向。多巴胺是氨基的邻苯二酚，近几十年来，多巴胺及其类似物在材料领域得到了广泛应用。多巴胺在一定条件下可以发生氧化自聚合，多巴胺的自聚合可用于对材料表面涂层修饰，制备出功能性的材料。因氧化自聚合最为简便和高效，多巴胺已在纺织领域得到广泛的研究，制备出具有亲水性、抗紫外线性和抗菌性的纺织品。
基于聚多巴胺的表面改性适用于任何基体材料，且对样品的外形和尺寸没有特殊要求，因此基于多巴胺研究几乎涉及各个领域，在纺织材料上也得到深入研究，其文献报道很多。虽然，多巴胺能在纤维材料上生成聚多巴胺，制备出功能纺织品，但是，从目前的文献报道来看，聚多巴胺在纺织材料上的改性技术缺乏实际应用的前景。其主要原因有：1）聚多巴胺反应时间长，多巴胺的形成机制复杂，聚多巴胺的颜色由黄色向黑色过渡，颜色生成强烈依赖于反应温度、反应时间和碱剂选择。即聚多巴胺的颜色很难控制成固定的颜色，导致改性过程难控制，其颜色的重现性较差。2）多巴胺容易吸附在纺织纤维表面，通过氧化自聚合生成聚多巴胺，但聚多巴胺的生成是一种多孔隙的松散结构，不能在纤维表面形成均匀的膜状结构，因此，不能满足纺织服装服用过程中对摩擦牢度和皂洗牢度的要求，即在使用过程中，聚多巴胺会大面积剥落而失去功能性，且脱落的聚多巴胺是一种粉尘颗粒，会对人体和环境产生污染。这是多巴胺或聚多巴胺在纺织纤维上不能很好应用的重要原因。在棉纤维上制备聚多巴胺，从纤维扫描电镜图可清晰观察到聚多巴胺的多孔隙的松散结构，当受到机械摩擦、机械剪切等外力作用，多孔隙的松散的聚多巴胺很容易脱落，这是多巴胺改性纺织纤维产生的最严重的问题，直接导致聚多巴胺很难在纺织领域得到应用。因此，聚多巴胺在纺织上的应用，其前提是解决聚多巴胺容易脱落的问题，满足使用过程中对摩擦和皂洗色牢度的要求，但是，采用现有溶液改性处理不能阻止聚多巴胺的多孔隙和松散结构的生成。
 技术问题
本发明采用多巴胺和活性染料同浴加工棉纤维，实现多巴胺的氧化自聚合与活性染料与纤维固着，既能丰富棉纤维的色彩，又能利用聚多巴胺的功能性；而且能在纺织纤维上形成致密的膜状的聚多巴胺，能满足纺织服装使用时对色牢度（如摩擦和家庭洗涤）的要求。另外，本发明采用多巴胺和活性染料同浴的轧染方法，结合浸轧棉织物卷装成卷堆置，聚多巴胺向纱线内部和纤维内部渗透，对纤维进行聚多巴胺改性。进一步公开堆置的条件，对棉纤维的溶胀作用利于多巴胺氧化自聚合形成致密的膜状的聚多巴胺，活性染料的选择范围也更广泛，其染色性能要优于现有活性染料轧堆工艺。实际应用表明，当多巴胺与活性染料同时存在时，能起到协同效应，既有利于聚多巴胺的生成，又促进了染料得色深度。
 技术解决方案
为达到上述发明目的，本发明采用的技术方案是：一种基于多巴胺和活性染料的织物轧堆染色方法，包括以下步骤：将活性染料、多巴胺、碳酸钠、硫酸钠、明矾、匀染剂、水混合，得到染色溶液；将织物连续浸轧所述染色溶液，然后卷装为圆筒状织物；再将圆筒状织物堆置，完成织物轧堆染色。
一种基于多巴胺和活性染料的染色织物及其制备方法，包括以下步骤：将活性染料、多巴胺、碳酸钠、硫酸钠、明矾、匀染剂、水混合，得到染色溶液；将织物连续浸轧所述染色溶液，然后卷装为圆筒状织物；再将圆筒状织物堆置，然后进行皂洗、水洗，烘干得到染色织物。
本发明公开了染色溶液及其在织物轧堆染色中的应用或者在制备织物轧堆染色整理液中的应用，将活性染料、多巴胺、碳酸钠、硫酸钠、明矾、匀染剂、水混合，得到染色溶液。
本发明中，以染色溶液的质量百分数为100%，所述染色溶液由以下质量百分数的原料组成： 。
优选的，以染色溶液的质量百分数为100%，所述染色溶液由以下质量百分数的原料组成： 。
优选的，以染色溶液的质量百分数为100%，所述染色溶液由以下质量百分数的原料组成： 。
   本发明中，浸轧时，轧液率为60～70%；所述堆置的温度为40～70℃，所述的堆置时间为1～5小时；优选的，所述堆置的温度为50～60℃，比如55～65℃，所述堆置时间为2～4小时浸轧时，轧液率为65～70%。
与现有技术在氧化阶段加入金属盐不同，本发明采用新的方法，利用多巴胺和活性染料同浴加工棉纤维，实现多巴胺的氧化自聚合与活性染料与纤维固着，有利于与多巴胺的配位结合和自聚合，解决了现有技术仅能增加纤维表面生成更多的聚多巴胺不利于获得良好的色牢度的问题。另外，本发明公开的方法中不需要单独的氧化处理，尤其不需要双氧水与金属离子共同存在下的氧化处理。多巴胺与活性染料起到协同效应，既有利于聚多巴胺的生成，又促进了染料得色深度。
 有益效果
由于上述技术方案运用，本发明具有下列优势：1）采用堆置的多巴胺和活性染料处理棉织物的工艺，纤维表面的聚多巴胺呈均匀致密的膜状结构，提高了耐摩擦色牢度和耐皂洗色牢度，抑制了聚多巴胺在纤维表面的多孔和松散结构。
2）当多巴胺和活性染料同时存在时，既能增加聚多巴胺的生成，又能提高棉织物染色深度，且丰富了基于聚多巴胺功能性棉织物的色泽，且耐摩擦色牢度和耐皂洗色牢度都不低于3-4级。
3）采用堆置染色技术适合活性染料染色棉纤维，热源选择热定形机的废热，能拓宽废热回用技术的应用，具有明显的节能降耗效果。

性能测试：K/S值光谱曲线：在 Ultranscan-XE 电脑测色配色仪上测试K/S值光谱曲线，绘制K/S值～波长曲线，以表示染色性能。
在 Model 670 型摩擦牢度仪上，按 GB/T3920-2008《纺织品色牢度试验  耐摩擦色牢度》测试色牢度。
水润湿角：在动态接触角测量仪上测试织物的润湿性能，注射液体为去离子水。
表面形貌：在S-4800型冷场发射扫描电镜（SEM）上观察PTFE膜的表面形貌，扫描之前采用喷金处理，以减少荷电效应。
表1为实施例一、实施例三、对比例四和对比例五制备的棉织物的水接触角、干摩擦色牢度和纤维表面形貌以及对比例六和对比例七制备棉织物的色牢度。可知，纤维上聚多巴胺都带来优异的润湿性。对比例四和对比例五制备的棉织物，聚多巴胺在纤维表面形成松散多孔的膜，分别见附图6和附图7，导致干摩擦色牢度仅为1级，摩擦色牢度很差，但是单独染料染色后，成卷堆置、平整堆置对色牢度没有影响。本发明技术下，聚多巴胺在纤维表面生成了致密光滑的膜，分别见附图4和附图5，即能控制聚多巴胺在纤维表面成膜结构，结果是干摩擦色牢度得到明显提高，达到甚至超过3-4级，与单独染料染色近似；这是现有技术多巴胺聚合改性不能解决的问题。
。
对比例一至对比例三，三种多巴胺浓度单独改性棉纤维的K/S值光谱曲线可知，当多巴胺浓度分别为1%（附图1的曲线A1）、1.5%（附图2的曲线A5）、2%（附图1的曲线A2）时，波长在370nm是聚多巴胺的特征吸收峰，其K/S值分别为7.90（1%）、8.10（1.5%）、7.76（2%）。即采用轧堆的多巴胺处理棉纤维，不同浓度的多巴胺对棉纤维得色深度的影响较小；但是进行干摩擦测试时，存在明显的聚多巴胺粉末脱落。
比较实施例一、实施例二染色加工可知，相同多巴胺浓度（1%）下，活性红3BFN浓度直接影响到棉织物K/S值（附图1）。波长为530nm为活性红3BFN的特征吸收峰，K/S值分别为5.00（0.5%活性红3BFN，附图1的曲线A3）和10.64（1.5%活性红3BFN，附图1的曲线A4），都大于单独活性红3BFN染色织物。在活性红3BFN的影响下，波长在370nm的特征吸收峰明显增大，K/S值分别为12.32（0.5%活性红3BFN）和15.73（1.5%活性红3BFN）。即活性红3BFN存在下，能提高370nm波长处的吸收峰。
比较实施例三、实施例四的染色加工可知，相同多巴胺浓度（1.5%）下，活性蓝M2GE浓度直接影响到棉织物K/S值（附图2）。波长为605nm为活性蓝M2GE的特征吸收峰，K/S值分别为6.47（0.2%活性蓝M2GE，附图2的曲线A6）和10.64（1.0%活性蓝M2GE，附图2的曲线A7），都大于单独活性蓝M2GE染色织物。在活性蓝M2GE的影响下，波长在370nm的特征吸收峰明显增大，K/S值由8.10（无活性蓝M2GE）增加至13.71（0.2%活性蓝M2GE）和14.72（1.0%活性蓝M2GE）。
比较单独活性嫩黄4GL、单独多巴胺、多巴胺和活性嫩黄4GL同浴的轧堆的染色加工可知，单独活性嫩黄4GL（浓度为1.0%）轧堆的染色棉织物，其特征吸收峰波长为430nm，K/S值为5.61（附图3的曲线A9）。单独多巴胺（浓度为1.0%）轧堆的棉织物，其特征吸收峰波长为370nm，K/S值为7.90（附图3的曲线A1）。当多巴胺（浓度为1.0%）和活性嫩黄4GL（浓度为1.0%）同浴轧堆的染色棉织物，其K/S值分别为13.51（430nm）和10.1（370nm），附图3的曲线A8。这说明活性染料存在下，不仅能提高370nm特征吸收峰的强度，也提高了活性染料的得色深度，且干摩擦色牢度3-4级；作为对照，单独活性嫩黄4GL得到的染色棉织物干摩擦色牢度为3-4级。
在棉纤维上制备聚多巴胺，从纤维扫描电镜图可清晰观察到聚多巴胺的多孔隙的松散结构，当受到机械摩擦、机械剪切等外力作用，多孔隙的松散的聚多巴胺很容易脱落，这是多巴胺改性纺织纤维产生的最严重的问题，直接导致聚多巴胺很难在纺织领域得到应用，但是现有改性处理不能阻止聚多巴胺的多孔隙和松散结构的生成。本发明采用新的染料溶液，结合轧堆工艺，解决了聚多巴胺容易脱落的问题，满足使用过程中对摩擦和皂洗色牢度的要求。
