    • A process for reduction clearing dyed or printed polyester textiles, which comprises adding, to an acidic dyeing liquor or a wash bath, an aftertreatment composition comprising as components a) at least one compound of the formula (I) Am[(CR1R2)mSO2M]p,q  (I)  where A is NR33−q or OR42−p; p,q means q when A is NR33−q, and p when A is OR42−p; R1, R2, R4 are each hydrogen or C1-C6-alkyl; R3 represents identical or different radicals selected from the group consisting of hydrogen, C1-C20-alkyl, C3-C8-cycloalkyl opt. substituted by from one to three C1-C4-alkyl radicals; M is the equivalent of an ammonium, alkali metal or a kaline earth metal ion; m is 0 or 1; p is 1 or 2; and q is 1, 2 or 3, subject to the provisos that at least one of R1, R2, R4 is C1-C6-alkyl when A is OR42−p and that, if m is 0: the compound of formula (I) is S2O4M2, and the compound of the formula (I) is used together with sufficient acid acceptor to raise the pH of the dyeing liquor or of the wash bath by from 1 to 3 units, b) optionally at least one compound of the formula (II) A[CR1R2)SO3M]p,q  (II)  where A, R1, R2, R3, R4, M, p,q p and q are each as defined for the formula (I), although the specific choice of these variables does not have to be the same for the compounds of the formulae (I) and (II) c) and optionally further additives.
    • 一种用于还原清除染色或印花聚酯纺织品的方法,其包括向酸性染色液或洗涤浴中加入后处理组合物,所述后处理组合物包含作为组分的至少一种式(I)化合物,其中A为NR 3 -q或OR 4 = 2-p; p,q表示当A是NR 3-q时的q,当A是OR 4或2-p时,p表示p。 R 1,R 2,R 4各自为氢或C 1 -C 6 - 烷基; R 3表示选自氢,C 1 -C 20 - 烷基,C 3 -C 8 - 环烷基选择的相同或不同的基团。 被一至三个C 1 -C 4烷基取代; M相当于铵,碱金属或碱土金属离子; m为0或1; p为1或2; 并且q是1,2或3,条件是当A是OR 4或2-p时,R 1,R 2,R 4中的至少一个是C 1 -C 6 - 烷基, 如果m为0,式(I)化合物为S2O4M2,式(I)化合物与足够的酸受体一起使用,以使染液或洗浴液的pH值提高1至3 单元,b)任选地至少一种式(II)的化合物,其中A,R 1,R 2,R 3,R 4,M,p,qp和q各自如 通式(I)虽然这些变量的具体选择对于式(I)和(II)c)和任选的其它添加剂的化合物不必相同。
