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.
Abstract:
Compositions and a process for dyeing and printing synthetic materials of polyacrylonitrile, polyamides, or polyesters which contain anionic groups which comprises using a treating composition for aforesaid materials which consists of an aqueous dispersion of a basic dyestuff salt and a polynuclear aromatic sulfonic acid whereby the fixing times are reduced and fast and level dyeings are produced.
Abstract:
This invention relates to the production of basic modified polyamides produced by the polycondensation of lactams or omega -aminocarboxylic acids with 0.1 to 5 mol of triamines of the formula H2N - (CH2)n - NH - (CH2)n - NH2 where n equals 2 to 6 PER 100 MOL OF LACTAM AND 2 EQUIVALENTS OF CARBOXYL GROUPS IN THE FORM OF DICARBOXYLIC ACIDS AND MONOCARBOXYLIC ACIDS PER MOL OF TRIAMINE, USING A MOLAR RATIO OF MONOCARBOXYLIC ACIDS TO DICARBOXYLIC ACIDS OF BETWEEN 10 : 1 AND 1 : 20, WHICH POLYAMIDES ARE DYED WITH REACTIVE DYES.
Abstract:
Synthetic fibers containing NH-groups, e.g. polyamides are dyed by exhaustion in a dyebath comprising halogenated hydrocarbon and the amine salt or adduct of a dyestuff containing carboxyl and/or sulfonic acid groups.
Abstract:
PROCESS FOR THE MANUFACTURE OF HIGH BULK TEXTILE MATERIALS OF POLYACRYLONITRILE BY HEAT TREATMENT OF TEXTILE MATERIALS CONSISTING OF POLYACRYLONITRILE FIBRE MATERIALS OF DIFFERENT THERMAL SHRINKABILITY, CHARACTERISED IN THAT THE HEAT TREATMENT IS CARRIED OUT IN CHLORINATED HYDROCARBONS WHICH OPTIONALLY CONTAIN SMALL AMOUNTS OF WATER AND SMALL AMOUNTS OF EMULSIFIERS.
Abstract:
Process for dyeing cellulose fibres and textile materials containing cellulose fibres with water-soluble reactive dyestuffs by the exhaustion method, characterized in that it is carried out using dye liquors, the particular fibre-reactive reactive dyestuff content of which is less than 10% of the total content of fixed dyestuff in the end dyeing.
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.
