Description

合成纤维同时洗脱整理剂和染色的方法
本发明涉及对用矿物油整理剂、硅油整理剂或这两种整理剂整理过的合成纤维或合成纤维纺织材料同时进行整理剂洗脱和染色的一步工艺法。这一方法通过用含有如下物料作为基本成分的水溶液处理纤维或纺织材料而完成:a)一种或多种选自由阴离子和两性表面活性剂组成的一类表面活性剂,b)一种或多种染料以及c)任选还含有一种或多种选自由非离子表面活性剂、萜烯烃类、萜烯醇类及它们与低级羧酸的酯类、山梨醇酯类和它们的烷氧基化合物、脂肪酸乙醇酰胺类、烷基聚苷类和溶剂组成的一类化合物。该处理在pH范围4.0-7.5,最终温度范围80-110℃,以及浴比5∶1-100∶1条件下进行。
可按照本发明处理的合成纤维例子为聚酰胺纤维,例如锦纶-6(贝纶和其他)或锦纶6,6、聚酯纤维、聚氨基甲酸乙酯纤维和其他本专业普通技术人员已知的纤维、和它们相互或各自的混合纤维,以及它们与植物和动物来源的其他纤维的混合纤维。本发明的方法特别涉及聚酰胺类组成的纤维和聚氨基甲酸乙酯类所组成的纤维,并涉及它们各自或彼此的混合纤维,以及它们与植物及动物来源的纤维的混合纤维。特别优选的是聚酰胺、聚氨基甲酸乙酯或聚酰胺/聚氨基甲酸乙酯混合物组成的纤维。将合成纤维纺织材料搓捻,或经其它机械纺织处理纱线和制成针织品或纺织品。对某些用途,例如生产袜子,则使用例如含有聚氨基甲酸乙酯纤维和卷曲的或未卷曲的聚酰胺纤维的混合纱。
为了改进纤维及由此制得的纱线的加工性能,给它们提供一种整理剂,该整理剂随后也存在于由此制得的纺织材料上。对于合成纤维来说,整理剂常见的是一种矿物油或一种硅油。然而,这些油性整理剂由于引起明显的污斑而影响纤维、纱和纺织材料的染色。从而,必需在染色工艺之前通过洗涤除去矿物油或硅油整理剂。这种预洗涤原则上是已知的,并且在已知的设备中进行。这一分离洗涤的缺点主要是需时间较长(洗涤约80-90分钟),需配置为此目的的分离设备,为这一工艺还需要工作人员,且产生必须排放的大量额外废水,以及在分离操作中为加热和冷却的能量消耗。染色工艺直至洗涤后才能进行,必须付出上述各项更新费用方能实施。
现已发现,如果所用的溶液包含有一种或多种选自由阴离子表面活性剂和两性表面活性剂组成的一类表面活性剂。并且还有任选一种或多种选自由非离子表面活性剂、萜烯烃类、萜烯醇类及它们与低级羧酸的酯类、山梨醇酯类和它们的烷氧基化合物、脂肪酸乙醇酰胺类、烷基聚苷类和溶剂组成的一类化合物,以及一种或多种染料,则可在同一时间,同一溶液,以一步法进行迄今的分离预洗涤和染色工艺。
因此,本发明提供了一种对用矿物油整理剂、硅油整理剂或这两种整理剂整理过的合成纤维或合成纤维纺织材料同时进行整理剂洗脱和染色的工艺方法,该方法包括用一种水溶液处理这些合成纤维或合成纤维纺织材料,该水溶液含有如下物料作为基本成分:
a)一种或多种选自由阴离子和两性表面活性剂组成的一类表面活性
  剂,
b)一种或多种选自由酸性染料、金属配合物染料和分散染料组成的
  一类染料,以及
c)任选一种或多种选自由非离子表面活性剂、萜烯烃类、萜烯醇类及它们与低级羧酸的酯类、山梨醇/甘露糖醇酯类及它们的烷氧基化合物、脂肪酸乙醇酰胺类、烷基聚苷类和溶剂组成物的一类化合物,处理时的pH范围为4.0-7.5,最终温度范围80-110℃,浴比为5∶1-100∶1。
因此,本发明的方法涉及使经整理剂处理而载有整理剂的合成纤维或纺织材料染色。在这一方法中,分离除去矿物油或硅油整理剂或这两种整理剂和染色仅在一种溶液中进行。本发明的方法在下文详细说明的条件下进行。
本发明方法合适的两性表面活性剂为含有C10-C22烃基的氧化胺、甜菜碱和磺基甜菜碱或它们的混合物。
优选的两性表面活性剂是下式的甜菜碱
Figure A9810892800051
其中X为单键或-CO-NH-(C2-C3烷基)-,以及R1和R2彼此独立地为氢、甲基或羟乙基。
这些甜菜碱包括下式此类化合物:氧化胺中,优选下式的此类化合物:其中X,R1和R2各自是如上所定义的。
特别优选的氧化胺是下式此类化合物:
合适甜菜碱(II)的具体例为:十二烷基-二甲基甜菜碱、椰子烷基-二甲基甜菜碱、十四烷基-二甲基甜菜碱、十八烷基-二甲基甜菜碱、牛油烷基-二甲基甜菜碱、油基-二甲基甜菜碱、椰子烷基-双-羟乙基甜菜碱、硬脂酰-双-羟乙基甜菜碱、牛油烷基-双-羟乙基甜菜碱。
合适氧化胺(IV)的具体例为:例如十二烷基-二甲基氧化胺、椰子烷基-二甲基氧化胺、十四烷基-二甲基氧化胺、十八烷基-二甲基氧化胺、牛油烷基-二甲基氧化胺、油基-二甲基氧化胺、椰子烷基-双-羟乙基氧化胺、硬脂酰-双-羟乙基氧化胺、牛油烷基-双-羟乙基氧化胺。
合适的阴离子表面活性剂例如为C10-C22链烷醇、链烯醇的硫酸化产物,或它们与1-50单元环氧乙烷(EO),优选1-40单位EO的反应产物。这些硫酸化产品可以以碱金属、碱土金属、铵、胺或乙醇胺的盐类存在。其他的阴离子表面活性剂是C12-C18脂肪酸皂类、烷基磺酸盐和烷基苯磺酸(它们以上述盐的形式存在)。其他合适的阴离子表面活性剂是化学式为C8-C20烷(链烯)基-(O-CH2-CH2-)x-O-CH2-COO-M的聚醚类羧酸盐,其中x是2-30,优选为3-10,而M为一种上述成盐阳离子等价物。
上述各种两性和阴离子表面活性剂广泛地在纺织品处理的领域中使用,并为本领域的普通技术人员所公知。
通过使用上述两性和阴离子表面活性剂及进一步任选其他化合物,可以消除经整理剂处理的上述合成纤维或纺织材料上的矿物油、硅油或矿物/硅油整理剂,而不会影响同时进行对合成纤维或纺织材料的染色。实际上,意外地达到了高均匀度的染色。矿物油整理剂经常在聚酰胺和聚酯纤维的场合下使用,而硅油整理剂经常在聚氨基甲酸乙酯纤维的场合下使用。矿物油例如是粘度范围为10-40mPa.s的石蜡油;硅油例如是粘度范围为3-100mPa.s的M级油。已发现,阴离子表面活性剂消除矿物油整理剂较好,而两性表面活性剂对消除硅油整理剂较佳。从而,在混合纤维场合下,例如聚酰胺/聚氨基甲酸乙酯或聚酯/聚氨基甲酸乙酯,可以使用阴离子和两性表面活性剂的混合物。
处理溶液另外还包含有染料,优选酸性染料、金属配合物染料或分散染料。所有这些染料均为本领域普通技术人员已知的,不需作进一步说明。
处理溶液任选地还含有一种或多种选自由非离子表面活性剂、萜烯烃类、萜烯醇类及它们与低级羧酸,例如C1-C4羧酸,优选乙酸形成的酯类、山梨醇/甘露糖醇酯类及它们的烷氧基化合物、脂肪酸乙醇酰胺类、烷基聚苷类和溶剂组成的物类的化合物。
非离子表面活性剂例如是有9-13个碳的脂肪化学醇或羰基合成醇之类的醇,或脂肪化学胺或羧酸,它们已与3-10个单位EO并任选另加2-5个环氧丙烷(PO)反应过。在这些反应产物中,优选上述碳原子数的醇类。这些非离子表面活性剂是本领域普通技术人员已知的,从而不需作进一步说明。
