  • Liquid dyes are dye processing agents that have developed rapidly in recent years. Due to their advantages such as simple production method, convenient operation, energy saving and emission reduction, and improved dyeing performance, they are highly valued by printing and dyeing factories and have a relatively fast development speed.
  • the preparation of liquid dyes has the following characteristics: 1.
  • the liquid dye does not need to be processed by drying, granulation, molding, etc., so the processing equipment is greatly simplified, the production process is obviously shortened; 2.
  • the storage stability of liquid dyes is poor, and precipitation is easy, so Requiring the rational use of high-efficiency dispersing agents and other supporting additives, the formulation research and preparation process of the products need to be refined; 3.
  • Advanced micro-emulsification, ultra-fine pulverization and dispersion suspension processing technology is required.
  • For water-insoluble dyes It is also possible to produce a stable liquid dye dispersion by wet ultrafine pulverization technology; 4. It is especially suitable for the production and processing of disperse dyes, thereby further purifying the disperse dyes, reducing impurities and improving purity.
  • Liquid disperse dyes have the following basic requirements: 1. The liquid dispersion system should be stable and can be stored under a longer period of time; 2. It has good fluidity and can be pumped and can be dumped; 3. At room temperature Or cold water is easy to disperse or dissolve, can be miscible or mixed with similar or other dyes; 4, does not contain toxic substances, PH is neutral; 5, should increase the dye concentration as much as possible; 6, can be applied to a variety of printing and dyeing processes .
  • liquid disperse dyes 1. Good application performance. In the printing and dyeing industry, powdery and granular dyes have been used for a long time. Dye dust is the most troublesome problem when mixing or preparing dyeing liquids, which not only affects The environment, which hinders labor protection, is often adhered to the ingredients of the ingredients or suspended in the formulated dye liquor foam. Large particle dyes that have not been dispersed or dissolved, especially dyes with low solubility and poor dispersion properties, have poor wettability and dispersion properties, and easily stick to each other to form agglomerates, which tend to cause defects in the fabric during dyeing, affecting product quality. . The liquid dye has substantially no such problems, and can significantly reduce the occurrence of dyeing rickets.
  • the degree of migration of dyes is related to many factors. It is mainly related to the content of additives in the dye. Studies have shown that many dispersants and wetting agents have a tendency to increase the migration of dyes. In the liquid dye processing formulation, since the amount of the dispersant is greatly lower than that of the solid dye (generally equivalent to one-fifth or less of the liquid dye), the degree of migration during the post-treatment of the dyeing process is effectively reduced. : 3, can improve the dye up rate, some water-insoluble dyes, especially disperse dyes when dyeing polyester or other synthetic fibers, the fineness of the particles is more important.
  • the powdery and granular dyes are subjected to a drying process after pulverization, which inevitably causes agglomeration of a part of the particles, and the dispersion property is lowered. Therefore, the solid dye is coarser than the particles of the liquid dye, and the same amount of the powder dye and the liquid dye are dyed with the hot melt method, and as a result, the dye dye has a higher dye uptake rate than the powder dye, and the maximum difference sometimes reaches 50%. the above. Moreover, powder dyes are prone to defects when hot melt dyeing, while liquid dyes can avoid such problems. 4. Liquid dyes reduce production costs. Liquid dyes do not require a drying process or dry pulverization when compared with solid dyes.
  • Dry mix process This greatly shortens the production process. Drying is a high-energy operation process in production. It saves production cost by eliminating drying.
  • the use of water in liquid dyes instead of some additives has greatly reduced the cost of raw materials, so liquid The dye can effectively reduce the raw material cost and production cost of the dye; 5. Reduce the COD in the dye residue; because the dye dispersant and other additives used in the liquid dye are relatively small, the COD content in the dye residue is naturally reduced; 6. The chroma of the dye residue is reduced. Since the liquid dyeing rate is higher than that of the powder dye, the residual dye in the residual liquid after dyeing is less, and the color of the residual liquid is significantly reduced. 7.

节能减排型高强度液体分散染料及其制备方法以及应用 技术领域
本发明涉及一种节能减排型高强度液体分散染料及其制备方法以及应用，所述的液体分散染料适用于合成纤维着色，特别是涤纶及其混纺织物的染色和印花。
背景技术
近年来，随着环境问题日益严重，国家对环保方面的要求越来越高，对纺织印染行业的整治也越来越严格，纺织印染企业迫切需要节能减排的高强度染料。
液体染料是近年来发展比较快的染料加工剂型，由于其具有生产方法简便、使用操作方便、节能减排、可提高染色性能等优点，受到印染厂的高度重视，发展速度较快。
液体染料制备有如下特点：1、液体染料不需要干燥、造粒、成型等加工过程，因此加工设备大大简化，生产过程明显缩短；2、液体染料的贮存稳定性较差，容易产生沉淀，因此要求合理选用高效分散剂以及配套的其他添加助剂，对商品的配方研究、制备工艺更需要精益求精；3、需要采用先进的微乳化、超微粉碎分散悬浮体加工技术，对于非水溶性染料，也可以通过湿式超微粉碎技术，生产加工稳定的液体染料分散体；4、尤其适合于分散染料的生产加工，从而使分散染料进一步得到净化处理，减少杂质，提高纯度。
液体分散染料具备以下几项基本要求：1、液体的分散体系应较稳定，能在较长期时间下下贮存；2、具有良好的流动性，可以用泵输送，可以倾倒；3、在常温下或冷水中易于分散或溶解，能与同类或其他染料混溶或拼混；4、不含有毒物质，PH为中性；5、应尽可能提高染料浓度；6、可适用于多种印染工艺。
液体分散染料的优点：1、良好的应用性能，在印染工业中，长时期以来一直使用粉状、粒状染料，在调浆或配制染液时，染料粉尘是最令人头疼的问题，不但影响环境，有碍劳动保护，而且常黏附在配料的用具上或在配制的染液泡沫中悬浮。没被分散或溶解的大颗粒染料，特别是溶解度小、分散性能差的染料，润湿性能和分散性能都较差，容易相互黏结成团块，在染色时容易使织物形成疵点，影响产品质量。而液状染料基本不存在上述问题，可显著降低染色疵病的产生。2、减少泳移现象，染料的泳移是一个值得注意的问题，染料的泳移程度与许多方面的因素有关。又主要与染料中助剂的含量有关。有关研究表明，许多分散剂、润湿剂都有增加染料发生泳移的趋势。在液体染料加工配方中，由于分散剂的用量较之固状染料大大降低(一般相当于液体染料的五分之一或更少)，所以也就有效降低了染色加工后处理时的泳移程度：3、可以提高上染率，一些非水溶性染料，特别是分散染料在染涤 纶或其他合成纤维时，颗粒细度比较重要。通常粉状、粒状染料在粉碎后需经过干燥过程，这就不可避免地使部分颗粒产生凝聚，分散性能下降。因此，固状染料较液体染料的粒子粗大，相同量的粉状染料和液体染料用热熔法染涤纶，其结果是液体染料比粉状染料的上染率高，最大差别有时可达到50％以上。而且热熔法染色时粉状染料易产生疵点，而液体染料却可以避免这样的问题；4、液体染料降低生产成本，液体染料同固状染料比较，不需要干燥过程，也不需要干粉碎和干拼混过程：这就大大缩短了生产工艺流程。干燥在生产中是一个高耗能操作过程，省去了干燥就节省了生产成本，另外，在液体染料中用水代替了部分助剂的使用，在很大程度上也降低了原料成本，所以液体染料可以有效降低染料的原料成本和生产成本；5、减少染色残液中的COD，由于液体染料中使用的染料分散剂及其它助剂相对较少，自然就使得染色残液中COD含量降低；6、降低了染色残液的色度，由于液体染料上色率高于粉状染料，染色后残液中残余的染料较少，残液的色度明显降低；7，随着现在劳动力市场的成本增加，越来越多的印染企业使用了自动化工艺设备，液体分散染料特别适合自动化计量，随之得到了大量的应用。
现有市场上的液体分散染料的原染料重量百分比控制范围为17.9％～36％、助剂重量百分比控制范围为4.5％～14.4％、助剂与原染料重量百分比控制范围为0.25～0.4∶1，存在液体染料强度偏低，印染厂在应用时存在些局限性，助剂含量偏高，染色后残液的色度abs值、COD偏高，还没有真正实现最佳的节能减排的目的。

本发明还提供一种织物，通过本发明所述的节能减排型高强度液体分散染料进行染色和印花制得。
在下列各实施例中，本发明选用分散橙288、分散橙30、分散橙31、分散橙61、分散红145、分散红153、分散红167、分散蓝54、分散蓝56、分散蓝60、分散蓝73、分散蓝77、分散蓝79、分散蓝165、分散蓝183：1、分散蓝291、分散蓝291：1、分散紫93中的一种或多种随意混合与并且助剂和水按表1的比例拼混后，用砂磨机进行研磨分散制成一种节能减排型高强度液体分散染料。
所述分散染料原染料和助剂均为已知的化合物并且可以在市场上购得，或者可由现有的方法制备。
表1：各个实施例的配方表。
Figure PCTCN2018000135-appb-000001
对比例1：将55.00克分散染料原染料、32.50克扩散剂MF加入162.50克水，用砂磨机进行研磨分散，制成液体分散染料。
对比例2：将43.50克分散染料原染料、43.50克扩散剂CNF加入161.50克水，用砂磨机进行研磨分散，制成液体分散染料。
将实施例1和对比例1-2的液体分散染料进行性能测试。具体测试方法如下：称取 1.0克实施例1-11和对比例1-2的液体分散染料以及市售的粉状染料分别置于5000ml的水中，制成分散染料悬浮液。吸取50ml分散染料悬浮液与50ml的水混合，用醋酸调节染浴pH到5，然后升温到60℃，同时分别放入2g聚酯纤维进行高温高压染色，在35分钟内升温到130℃，保温45分钟，冷却到80℃取样。
观察布样色光并采用GB/T6688-2008中规定的方法测其染料强度，用紫外可见分光光度计UV-2550测其染色残液在波长为380-750nm的色度abs值，用GB11914-89化学需氧量一重铬酸盐法测定其染色残液COD，测得数据见表2。
表2：各个实施例以及对比例的检测数据表。
Figure PCTCN2018000135-appb-000002
由表2可知，实施例1-11的液体分散染料与对比例1-2相比，出现沉淀的时间得到了延长，为运输和使用带来了极大的方便。并且实施例1-11的液体分散染料与对比例1-2以及粉状染料相比，染色残液色度浅、COD低，更加环保。
