Definitions

• This invention relates to dyeing of cellulosic textile materials and more particularly to a process of dyeing such materials with a combination of sulfur dyestuffs and reactive dyestuffs to obtain improved wet fastness properties, especially when washing the dyed textile materials with peroxide.
• substantially improved dyeing properties may be obtained by applying the sulfur dyestuff to the textile material, and prior to oxidation of the sulfur dye-stuff, applying the reactive dyestuff in conjunction with suitable chemicals, and subsequently oxidizing the sulfur dyestuif and finishing the dyed goods.
• the process is carried out in this sequential manner, and particularly when the reactive dyestuif is applied before the previously applied sulfur dyestuff is oxidized, more vivid colors and improved fastness to washing is obtained than heretofore possible with the prior art processes.
• the textile material to be treated in accordance with this invention may be in any of the usual forms, such as fibers, yarns, and woven or knitted fabrics.
• the basic fib'er of this material may be any of the presently known cellulosic textile fibers, e.g. cotton, rayon, linen.
• blends or mixed fabrics containing two or more of the above synthetic and cellulosic fibers may be dyed satisfactorily by the dyestuff compositions of this invention.
• sulfur dyestuff component any of the commonly known sulfur dyestuffs may be employed, such as sulfur dyestuffs insoluble and soluble in water.
• sulfur dyestuffs insoluble and soluble in water are especially suited for the last-mentioned group of sulfur dyestuffs.
• alkali salts of thiosulfonic acids of sulfur dyestuffs are especially suited for the last-mentioned group of sulfur dyestuffs.
• any of the commonly known reactive dyestuffs may be employed, such as for example those with haloacetyl-, ,B-halopropionyb, acryloyl-, and ,B-phenylsulfonylpropionyl-arnino groups.
• Particularly suitable are reactive dyestuffs containing as a reactive residue a halotriazine-, halopyrimidine-, or halopyridazine residue, or the residue of a halopyridazineor haloquinoxaline-carboxylic acid.
• Example 1 A dyeing of Hydrosol Fast Yellow G (C.I. Solubilized Sulfur Yellow 5 being the thi-osulfonic acid of C.I. Sulfur Yellow 5, the constitution of which is described in Collection Czechoslov. Chem. Commun., vol. 27 (1962), pp. 1533-48) on cotton yarn (obtained with of the dyestuff, 4 g./l calcined sodium carbonate, 20 g./l. calcined sodium sulfate, and 1.2 g./l. sodium hydrosulfide in a liquor ratio of 1:20 at C.) is rinsed and treated at 90 .C. during 30 minutes in a fresh bath with 2% Cibacron Scarlet 2G (C.I.

Commun, vol. 25 (1960), pp. 2794-), 20 g./l. calcined sodium sulfate, and 5 g./l. calcined sodium carbonate in a liquor ratio of 1:20. Subsequently, the dyeing is rinsed, oxidized at 40 C. with a liquor containing 1 g./l. sodium perborate, soaped, and rinsed again. A vivid orange dyeing of a very good fiastness to washing and to washing with peroxide is obtained. 7
