提高色泽深度的方法
摘要：
本发明涉及提高染色天然或合成聚酰胺纤维材料的色泽深度的方法，所述方法包括在染色之前、当中或之后采用包含式(1)的化合物的液体处理纤维材料，其中R为卤素、C1－C12烷基、C5－C24芳基、C6－C36芳烷基、－OR1或－NR1R2，R1和R2各自独立为氢、C1－C12烷基(未取代或用一个或多个羟基、氨基、巯基、羧基、磺基、C1－C12烷基磺酰基、C5－C24芳基磺酰基或C6－C36芳烷基磺酰基取代)、C5－C24芳基(未取代或用一个或多个羟基、氨基、羧基、磺基、C1－C12烷基磺酰基、C5－C24芳基磺酰基或C6－C36芳烷基磺酰基取代)或C6－C36芳烷基(未取代或用一个或多个羟基、氨基、羧基、磺基、C1－C12烷基磺酰基、C5－C24芳基磺酰基或C6－C36芳烷基磺酰基取代)，X和Y各自独立为巯基、－NR3R4或－N+R3R4R5A－，其中R3、R4和R5各自独立为氢或C1－C12烷基，A－为氯离子、溴离子、碘离子、硫酸根离子或甲基硫酸根离子，R6和R7各自独立为氢或C1－C12烷基，x和y各自独立为2至12的数。
摘要（英）：

The invention relates to a method of increasing the depth of shade of dyed natural or synthetic polyamide fibre materials, which comprises treating the fibre material before, during or after dyeing with a liquor comprising a compound of formula (1) wherein R is halogen, C1-C12alkyl, C5-C24aryl, C6-C36aralkyl, -OR1 or -NR1R2, R1 and R2 being, each independently of the other, hydrogen, C1-C12alkyl unsubstituted or substituted by one or more hydroxy, amino, mercapto, carboxyl, sulfo, C1-C12alkylsulfonyl, C5-C24arylsulfonyl or C6-C36aralkylsulfonyl groups, C5-C24aryl unsubstituted or substituted by one or more hydroxy, amino, carboxyl, sulfo, C1-C12 alkylsulfonyl, C5-C24arylsulfonyl or C6-C36aralkylsulfonyl groups, or C6-C36aralkyl unsubstituted or substituted by one or more hydroxy, amino, carboxyl, sulfo, C1-C12alkylsulfonyl, C5-C24arylsulfonyl or C6-C36aralkylsulfonyl groups, X and Y are, each independently of the other, mercapto, -NR3R4 or -N<+>R3R4R5 A<->, wherein R3, R4 and R5 are, each independently of the others, hydrogen or C1-C12alkyl and A<-> is chloride, bromite, iodide, sulfate or methylsulfate, R6 and R7 are, each independently of the other, hydrogen or C1-C12alkyl, and x and y are, each independently of the other, a number from 2 to 12.
