摘要:
A process for indigo dyeing of wool and wool blends comprising the steps of subjecting the wool and wool blends to a step of pretreatment by impregnation with a shrink resistance agent, subjecting the pretreated wool and wool blend yarns to the step of indigo dyeing and post dyeing, wherein the step of dyeing and post dyeing includes a single step or a plurality of steps of impregnation of the pretreated wool and wool blends in an indigo dye bath followed each time by the step of oxidation.

摘要:
An improved process for dyeing of fibre material, especially textile fibres, by applying to the fibre material at a temperature below the absorption temperature of the dyestuffs and with a goods-to-liquor ratio of 1:1.5 to 1:4, a concentrated aqueous dye liquor, said concentrated aqueous dye liquor containing at least one dyestuff which, in the case of the substrate to be dyed, has affinity to the fibres and which is either soluble or dispersible in water and 0.2 to 10 g/l, preferably 2 to 5 g/l, of at least one nonionic, surface-active agent from the class of ethylene oxide addition products and having a cloud point below 85.degree. C., and finishing of the dyeing by means of a heat treatment, e.g. introduction of saturated steam, superheated steam or hot air, preferably by heating from without, at temperatures of 95.degree. to 140.degree. C.
摘要:
Synthetic fibers and synthetic fiber textile materials finished with mineral oil finishes, silicone oil finishes or both can be simultaneously stripped of these finishes and dyed in one liquor comprising as essential ingredientsa) anionic and/or amphoteric surfactants,b) dyes, andc) optionally further compounds selected from the group consisting of the nonionic surfactants, the terpene hydrocarbons/alcohols, sorbitol esters and their alkoxylates, fatty acid ethanolamides, alkylpolyglycosides and solvents.The treatment is carried out at pH 4.0 to 7.5 at 80-110.degree. C. and at a liquor ratio of 5:1 to 100:1.

摘要:
The present invention relates to a method of dyeing polyester-containing textile material characterised in that the textile material is treated with a liquor containing (a) at least one disperse dye and (b) at least one compound of the formula (1), wherein G1 and G2, independently of one another, are C1-C4alkyl or together are pentamethylene, Z1 and Z2 are methyl, Or Z1 and Z2 together form a bridging member which is unsubstituted or substituted by an ester, ether, hydroxyl, oxo, cyanohydrin, amido, amino, carboxyl or urethane radical, and E is oxyl or hydroxyl.

An improved process for dyeing of diverse fibre material, especially textile fibres, by applying to the fibre material at a temperature below the absorption temperature of the dyestuffs a concentrated aqueous dye liquor and with a goods to liquor ratio of 1:1.5 to 1:4, the said aqueous dye liquor containing at least one dyestuff which, in the case of the substrate to be dyed, has affinity to the fibres and which is either soluble or dispersible in water and 0.2 to 10 g/l, preferably 2 to 5 g/l, of a non-foaming anionic dispersing agent from the class of aromatic sulphonic acids or the water-soluble salts thereof, and finishing of the dyeing by means of a heat treatment, e.g. introduction of saturated steam, superheated steam or hot air, preferably by heating from without, at temperatures of 95.degree. to 140.degree.
