Abstract
式(I)的活性染料,其中R1和R2各自独立地为氢或未取代或取代的C1-C4烷基,A是C2-C8被氧间隔的亚烷基,和Y是式-SO2-Z的纤维用活性基,其中Z是乙烯基或-CH2-CH2-U基,而U是在碱性条件下可除去的基团。这种染料特别适合于棉花的染色,且得到的染色品具有优良的综合性能。
Description
本发明涉及新型活性染料,其制备方法和其在染色或印染织物纤维材料中的应用。
新近,用活性染料染色的实践导致对染色质量和染色方法的益处提出了更高的要求。结果,仍然需要具有改进性能的,特别是就其应用而言的新型活性染料。
现今,染色要求具有足够直接性的活性染料,并且同时未固着的染料要很容易洗去。它们还应具有良好的着色率和高活性。目标特别是提供具有高固着度的染色。已知的染料不能在所有性能上满足这些要求。
因此,构成本发明基础的问题是为纤维材料的染色和印染找到新的改进的活性染料,其具有上述的高质量。这类新型染料特别应表现出高固着率和高纤维-染料结合稳定性;作为染料,还应该是未固着到纤维上的部分容易洗去。该染料还应产生具有良好综合性能如耐光性和耐湿性的染色。
已经证实,上面提出的问题以由下面定义的新型染料很好地解决。
因此本发明涉及式(1)的活性染料式中
R1和R2各自独立地为氢或未取代或取代的C1-C4烷基,
A是被氧间断的C2-C8亚烷基,
X是卤素,和
Y是式(2)的纤维用活性基
-SO2-Z (2)式中
Z是乙烯基或-CH2-CH2U基,而U是在碱性条件下的可除去的基团。
作为R1和R2的C1-C4烷基,可考虑的分别独立地为如甲基、乙基、丙基、异丙基、丁基、仲丁基、叔丁基和异丁基,优选甲基或乙基,尤其是甲基。上面指出的烷基可以是未取代的,或被例如羟基、磺基、硫酸根、氰基或羧基取代。
作为X的卤素,可考虑如氟,氯和溴。
作为离去基团U,可考虑如-Cl、-Br、-F、-OSO3H、-SSO3H、-OCO-CH3,-OPO3H2、-OCO-C6H5、-OSO2-C1-C4烷基和-OSO2-N(C1-C4烷基)2。
U优选-Cl、OSO3H、-SSO3H、-OCO-CH3、-OCO-C6H5或-OPO3H2,特别是-Cl或-OSO3H,更尤其是-Cl。
对于A,可考虑如式-(CH2)2-O-(CH2)2-、-(CH2)3-O-(CH2)2-或-(CH2)3-O-(CH2)3-的基团。
优选的本发明的活性染料是其中R1和R2各自独立地为氢或C1-C4烷基,尤其是氢。
优选的本发明的活性染料是其中X为氟或氯,尤其是氯。
在本发明的活性染料中A优选为被氧间断的C2-C6亚烷基,尤其是C2-C4亚烷基,例如-(CH2)2-O-(CH2)2-。
优选的本发明的活性染料是其中式-A-Y-的基团为式(3)的基团
-(CH2)2-4-O-(CH2)2-4-SO2Z (3),尤其是式(3a)的基团
-(CH2)2-O-(CH2)2-SO2Z (3a),其中
Z是乙烯基,β-氯乙基或β-硫酸根合乙基,特别是乙烯基或β-氯乙基。
因为上述该方法的步骤可以按不同的顺序进行,所以同样不同方法的变种是可能的。反应一般分步进行,特定反应组分之间的简单反应顺序最好由现行的条件确定。例如约1摩尔当量的式(6)的胺与约1摩尔当量的氰尿酰卤反应,然后将得到的产物与约1摩尔当量的式(5)化合物缩合。在另一个方法变体中,例如约1摩尔当量的式(5)化合物与约1摩尔当量的氰尿酰卤反应,然后将所得到的混合物与约1摩尔当量的式(6)化合物缩合。
个别的缩合反应例如用本身已知的方法,通常是在水溶液中,在温度如0-50℃,尤其是0-10℃,和在pH如3-10,尤其是3-7下进行。
作为氰尿酰卤,合宜的如氰尿酰氯和氰尿酰氟,特别是氰尿酰氯。
最终产物可任选地发生进一步的变换反应。这种变换反应是例如把存在于Y中并能转变成乙烯基的活性基转变为其乙烯基形式,方法是用稀氢氧化钠溶液处理,例如β-硫酸根合乙基磺酰基或β-氯乙基磺酰基转变成乙烯基磺酰基。这类反应本身是已知的。
式(5)和(6)的化合物是已知的或可按已知的化合物制备。
按照本发明式(1)的化合物适于作为染色和印染广范围材料的染料,如含羟基或含氮的纤维材料。含氮纤维材料的实例包括丝、皮革、毛、聚酰胺纤维和聚氨酯。本发明的活性染料尤其适合于所有类型的纤维素纤维材料的染色和印染。这种纤维素纤维材料是例如天然纤维素纤维,如棉花、亚麻和大麻纤维,和纤维素和再生纤维素,优选棉花。本发明的活性染料也适于纤维素混纺织物,例如棉花和聚酰胺纤维混纺或特别是棉花/聚酯混纺的染色或印染。
本发明的活性染料可施加于纤维材料并以许多方式固着到纤维上,特别是以染料水溶液或印染浆的形式。它们适合于浸染法和也适用于用轧染法染色,按这种方法织品用染料水溶液(任选含盐)浸渍,在用碱处理或在碱存在下,任选在热作用下或在室温下存放数小时后染料被固着。固着后,染色品或印染品用冷和热水彻底漂洗,任选地添加具有分散作用和促进未固着的染料扩散的试剂。
本发明的活性染料的特征是高活性,良好的固着性和极佳的组合特征。因此,它们可应用于在低染色温度下的浸染法以及在轧染-蒸汽(Pad-Steam)法中仅需短的汽蒸时间。其固着度高,且未固着的染料容易洗去,吸色率和固着度之间的差异常地小,也就是说皂洗的损失很小。本发明的染料还特别适合于印染,尤其是在棉花上,但也适合于印染含氮纤维,例如毛或丝或含毛或丝的混纺织物。
用本发明的活性染料得到的染色品和印染品具有高着色力和高的纤维-染料结合稳定性,无论是在酸性和碱性范围内,以及它们还具有优良的耐光性和极佳的耐湿性,例如耐洗涤、耐水、耐海水、耐交染和耐汗湿,以及优良的耐氯、耐折叠、耐热压和耐摩擦。
下列的实施例有利于说明本发明。给出的温度是摄氏度,份是重量份以及百分数是指重量百分数,除非另有说明。重量份是指按千克与升之比的体积份数。

b)在4℃和pH7下,首先将下式
H2N-(CH2)2-O-(CH2)2-SO2-(CH2)2-Cl的化合物22.63份加到按a)所得反应混合物中,然后在温度4-6℃,通过加入20%苏打溶液调节pH为7.5。在24-34℃和pH7.5下再进行4小时缩合。然后用稀盐酸调节pH至6,然后在室温下搅拌过夜。
c)按照b)得到的反应混合物通过加入氢氧化钠溶液被调节到pH11,在该pH值和在室温搅拌35分钟。然后用稀盐酸将pH调节至6;通过过滤将所得反应混合物澄清,并在稍稍升温下通过真空蒸发浓缩。得到152.9份混合物,其含有相应于式(101)的游离酸形式的化合物,它把棉花染色为具有良好综合性能的红色。
染色操作I
于80℃将100份棉织物放入盛有45g/L氯化钠和2份由实例1得到的活性染料的1500份染色浴中。45分钟后于80℃加入20g/L纯碱。于该温度下再染色45分钟。然后将染色织物漂洗,在沸腾下用非离子洗涤剂皂洗15分钟,再次漂洗和干燥。
作为上述操作的替换,染色也可在60℃而不是在80℃进行。
染色操作II
将0.1份按照实施例1的染料溶于200份水中,并加入0.5份硫酸钠,0.1份均染助剂(以高级脂族胺和环氧乙烷的综合产物为基础)和0.5份乙酸钠。然后用乙酸(80%)把pH调节至5.5。将染色浴在50℃加热10分钟,然后加入10份羊毛织物。将染色浴在大约50分钟的时间内加热至100℃,并在该温度下染色60分钟。然后冷却至90℃,然后移出染色织物。用热和冷水洗涤该羊毛织物,然后旋压和干燥。
印染操作
在快速搅拌下将3份按实施例1得到的染料撒布到100份含50份5%藻酸钠增稠剂,27.8份水,20份尿素,1份间硝基苯磺酸钠和1.2份碳酸氢钠的储备增稠剂中。将如此得到的印染浆用于棉花织物的印染;干燥,并在饱合蒸汽中于102℃蒸烘印染织物2分钟。然后漂洗该印染织物,任选地于沸腾时皂洗,并再次漂洗和干燥。
