Abstract:
An improvement in the process for dyeing synthetic fibers containing anionic groups, e.g., acrylonitrile copolymers, with basic dyestuffs in chlorohydrocarbon dyebaths containing 0.1-4 percent by weight of water is obtained by utilizing a dyeing auxiliary having the formula WHEREIN R1 and R2, independently of one another are C14-C22-alkyl or C14-C22-alkenyl in which the total of the carbon atoms contained in R1 and R2 is 32-44; R3 is lower alkyl, haloalkyl or hydroxyalkyl; R4 is optionally substituted cycloalkyl, aralkyl or C1-C4-alkyl, or together with R3 forms a 5- or 6-membered heterocycle; and X( ) IS AN ANION.
Abstract:
Process for dyeing or printing NH-containing fibers with reactive dyestuffs containing at least one group reactive to the NH-group and more than 1 sulfonic acid group comprising adding as surface active compounds aminoxides with at least eight carbon atoms in one and the same radical.
Abstract:
New polyamine derivatives of the formula
IN WHICH R, R1, m, n, p and q have the measuring given below in the disclosure and a process for their manufacture. The polyamines are useful as textile plasticisers for synthetic fibres, preferably polyacrylonitrile fibre materials.
Abstract:
Synthetic fibers containing anionic groups, e.g. polyacrylonitrile modified with sulfonic acid groups, are dyed by exhaustion in a dyebath comprising: A. hydrocarbon chloride solvent; B. 0.1 to 4% of water based on the solvent; C. a basic dyestuff soluble in hydrocarbon chloride solvent; and D. an organic nitrogen compound containing at least 12 carbon atoms, e.g. a fatty amine such as dodecylamine.
