Abstract (en)
[origin: EP0784117A2] Dyeing of fibrous materials containing wool with anionic dyes is carried out in the presence of a wool preservative containing acrylamide homo- or copolymer. Also claimed is the use of polyacrylamide homo- or copolymers as anti-setting agents in exhaustion dyeing of fibrous materials containing wool. Preferably the (co)polymer has a molecular weight of 800000-15 x 10<6>. It is a homopolymer of acrylamide or copolymer with acrylic acid or vinyl acetate, especially of 70-100 wt.% acrylamide and 0-30 wt.% acrylic acid or vinyl acetate. In particular, the copolymer contains ≥ 70 wt.% acrylamide, more particularly 75-90 wt.% acrylamide and 10-25 wt.% acrylic acid.; and the homo- or copolymer has a molecular weight of (1-15) x 10<6>, more particularly (1.5-3) x 10<6>. The (co)polymer is used as an aqueous formulation. It is used in the dyebath in an amount of 0.0001-2, especially 0.0005-1 g/l. The wool preservative also contains hydrogen peroxide (H2O2).
