Abstract (en)
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).
Abstract (de)
Beschrieben wird ein Verfahren zum Färben von wollhaltigen Fasermaterialien mit anionischen Farbstoffen, welches dadurch gekennzeichnet ist, dass man diese Materialien in Gegenwart eines Wollschutzmittels enthaltend mindestens ein Acrylamid-Homo- oder -Copolymer färbt. Nach dem Verfahren sind reibechte egale Färbungen mit reduziertem Setting erhältlich.
