Abstract
A process for slop-padding textile cellulose material with anionic substantive dyes, which consists in applying to said material an aqueous dye liquor which, in addition to the dye, contains (a) a quaternization product of a polyalkylene oxide adduct of 2 to 100 moles of alkylene oxide and optionally 1 mole of styrene oxide with 1 mole of a fatty amine containing at least 8 carbon atoms, (b) an etherified N-methylolmelamine, and (c) an acid catalyst, if desired drying the impregnated cellulose material and then subjecting it to a heat treatment.
Claims27
A process for slop-padding textile cellulose material with anionic substantive dyes, which comprises applying to said material an aqueous dye liquor which, in addition to the dye, contains
- (a) a quaternisation product of a poly adduct
- (a.sub.1) of 2 to 100 moles of alkylene oxide with 1 mole of a fatty amine containing at least 8 carbon atoms, or
- (a.sub.2) of 2 to 100 moles of alkylene oxide and 1 mole of styrene oxide with 1 mole of a fatty amine containing at least 8 carbon atoms,
- (b) 2.5 to 15 g/l an etherified N-methylolmelamine, and
- (c) an acid catalyst,
- and then subjecting the textile material to a heat treatment.
An aqueous dyebath for slop-padding textile cellulose material which comprises at least one anionic substantive dye, a preparation containing (a) a quaternisation product of a poly adduct (a.sub.1) of 2 to 100 moles of alkylene oxide with 1 mole of a fatty amine containing at least 8 carbon atoms or (a.sub.2) of 2 to 100 moles of alkylene oxide and 1 mole of styrene oxide with 1 mole of a fatty amine containing at least 8 carbon atoms, and (b) an etherified N-methylolmelamine, and an acid catalyst.
