Abstract (en)
[origin: CA2036224A1] 1-17962/+ Process for dyeing wool with reactive dyes There is disclosed a process for producing non-skittery and level dyeings on wool with reactive dyes in the presence of an auxiliary combination, which process comprises dyeing wool with an aqueous liquor consisting of at least one reactive dye and an auxiliary combination comprising, as component (a), at least one compound of formula (1a) and, as component (b), at least one compound of formula (1b) wherein R1 and R2 are each independently of the other an aliphatic radical of 12 to 24 carbon atoms, Q and Q' are each independently of the other C1-C4alkyl, -CH2-CO-NH2, or A? and A'? are an anion, Z1,Z2,Z'1 and Z'2 are each independently of one another hydrogen, SO3M or PO3M, wherein M is hydrogen, alkali metal or ammonium, t1 and t2 are 1 or 0, when t1 and t2 are O,Z1,Z2,Z'1 and Z'2 are hydrogen or one of Z1,Z2,Z'1 and Z'2 is hydrogen and the other is SO3M or PO3M, m1, n1, P1 and q1 are integers, the sum of (m1+n1) being 2 to 15 and that of (p1+q1) being 25 to 200, and finishing the dyeing, irrespective of the depth of shade, in the pH range from 4.0 to 5.0. The dyeing process of this invention gives non-skittery and level dyeings, especially in light to medium shades of good light- and wetfastness properties.
