    • The invention concerns a process for the reductive post-cleaning of coloured or printed polyester-containing textiles and is characterized in that a mixture is added as a post-treatment agent to the acid dye liquor or the washing bath. Said mixture comprises as components: a) at least one compound of formula (I) Am[(CR R )mSO2M]p,q, in which A designates NR 3-q or OR 2-p, R , R , R designate hydrogen, C1-C6 alkyl, R designates identical or different groups selected from the group comprising hydrogen, C1-C20 alkyl, C3-C8 cycloalkyl, optionally substituted by between one and three C1-C4 alkyl groups, M is an equivalent of an ammonium, alkali or alkaline earth ion, m is 0 or 1, p is 1 or 2, q is 1, 2 or 3, at least one of the groups R , R , R being a C1-C6 alkyl when A stands for OR 2-p, and, when m equals 0: p, q assuming the value 2, and the compound of formula (I) is used in a mixture with an amount of acid-binding substance which is sufficient to increase the pH value of the dye liquor or washing bath by between 1 and 3 units; b) optionally at least one compound of formula (II) A[(CR R )SO3M]p,q, in which A, R , R , R , R , M, p and q have the same general meanings as in formula (I); and c) optionally further additives.
    • 一种用于着色或印刷的含聚酯的纺织品的还原清洗后处理步骤,其特征在于,加入到所述酸染液或洗涤浴中的后处理剂是包含a)式(I中的至少一种化合物作为组分)的混合物中上午[(CR <1> [R <2>)mSO2M] p,q,其中A = NR <3> 3-q或或<4> 2-p; [R <1>,R <2>,R <4>为氢,C1-C6烷基; [R <3> =从选自氢相同或不同的基团,C1-C20烷基,C3-C8环烷基任选被一个至三个C1-C4烷基; 铵,碱金属或碱土金属离子的M =当量; M = 0或1; P = 1或2; Q = 1,2或3,其中R <1>,R <2>,R中的至少一个<4>是一个C1-C6烷基,当A是OR <4> 2-P,并且其中用于所述 为p,q为2取,并在混合式(I)的与酸结合物质的使用量是足以降低染色液或洗涤浴的pH的化合物为1〜:·如果m是等于0 3个单位增加; b)任选地前者(II)A的至少一种化合物[(CR <1> [R <2>)SO3M] P,Q,其中A,R <1>,R <2>,R <3>,R <4> 中,M,p和q具有相同的一般意义与在式(I); c)和任选的其他添加剂。
