Description

3,294,474 Patented Dec. 27, 1966 United States Patent Ofiice 9 Claims. lei. s 2s This invention relates to dye compositions and methods of dyeing cellulosic textile materials therewith, and more particularly to dye compositions comprising as the principal constituents the alkali salts of thiosulfonic acids of sulfur dyestuffs, an alkali, a reducing agent for said sulfur dyestuffs and a reactive dyestuff as defined herein, said composition being capable of dyeing said textile materials in a single dye bath under controlled temperature conditions with good uniformity of color.
Heretofore, dyeing of textile materials with sulfur dyestuffs and reactive dyestuffs have usually been carried out in two dyeing steps, that is, using. separate dye baths for the sulfur dyestuffs and the reactive dyestuffs, which is objectionable with respect to the time requirement and required chemicals.
The dyestuff compositions of the present invention have simplified the dyeing operation and produced bet ter dyeing results with the combination of the sulfur dyestuffs and the reactive dyestuffs used in a single bath. This has been made possible by using the water soluble alkali salts of thiosulfonic acids of sulfur dyestuffs, instead of the usual sulfur dyestuffs, and by using an alkali that effects fixation of the reactive dyestufi and concurrently using a reducing agent that effects fixation of the sulfur dystuff onto the textile fiber.
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. Likewise, the basic fiber of this material may be any of the presently known cellulosic textile fibers, e.g. cotton, rayon, linen. Also, cellulosic constituents in blends or mixed fabrics may be dyed satisfactorily by the dyestutf compositions of this invention.
For the reactive dyestuff component, any of the commonly known reactive dyestuffs may be employed, such as for example those with haloacetyl-, B-halopropionyb, acryloyl-, and fi-phenylsulfonylpropionyl-amino 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.
Regarding the controlled temperature feature of the dyeing method of the present invention, this involves dyeing of the textile material with the dyestuff composition above mentioned containing the alkali salt of the thiosulfonic acid of a sulfur dyestuif, the reactive dyestuff and an alkali, such as for example sodium carbonate, at a relatively low temperature, e.g. about 30 C., for a period of minutes and then adding a suitable reducing agent, such as for example sodium sulfide or sodium hydrosulfide, and increasing the temperature of the dye bath to about 6090 C. for a further period of minutes; and subsequently rinsing and oxidizing the dyed textile material and applying the usual finishing operations.
A presently advantageous procedure for carrying out the dyeing process of the present invention comprises treating the cellulosic material to be dyed in a first step with dye liquors containing as an essential component, aside from the water-soluble alkali salt of the thiosulfonic acid of the sulfur dyestutf and the reactive dyestuff, only alkali which gives rise to the fixation of the reactive dyestuif, and then further treating at an elevated temperature, after the addition of the reducing agent necessary for the reduction of the sulfur dyestuff. Thus also the sulfur dyestuff goes onto the fiber, and after the usual finishing, full combination dyeings are obtained, having a very good uniformity.
Illustrative but non-limiting more specific examples of the dyestuff compositions containing a thiosulfonic acid group containing sulfur dyestuff in combination with a reactive dyestuff and the methods of dyeing textile materials therewith are as follows:
Example 1 A cotton cheese is processed in a circulating liquor containing 5% Hydrosol Fast Yellow-brown GL (C.I. Solubilized Sulfur Brown 60, C.I. No. 53326), 2% Procion-yellow M-RS (C.I. Reactive Yellow 4), 20 g./l. calcined sodium sulfate, and 10 g./l. sodium carbonate, during 45 minutes at 30 C. Then 7.5% of a 20% sodium hydrosulfide solution are added, dyeing is continued for a further 10 minutes at 30 C. and, after increasing the temperature of the liquor to C., for a further 30 minutes at this temperature. Subsequently, the material is rinsed, oxidized at 40 C. with a liquor containing 1 g./l. sodium perborate, soaped, and rinsed again. A deep yellow-brown dyeing of good uniformity is thus obtained.
Example 2 A cotton cheese is first treated in a circulating bath containing 5% Hydrosol Blue FFG (C.I. Solubilized Sulfur Blue 2, C.I. No. 53481), 2% Cibacron Turquoiseblue G (C.I. Reactive Blue 7 constitution described in Collection Czechoslov. Chem. Commun, vol. 25 (1960), page 2797), 20 g./l. calcined sodium sulfate, 20 g./l. calcined sodium carbonate, and 7.5% of a 20% sodium hydrosulfide solution during 10 minutes at 30 C.; the temperature of the liquor is then increased during 20 minutes to 90 C., the material is dyed during 30 minutes at this temperature, then cooled down to 50- 60 C., and treated for a further 10 minutes at this temperature. Subsequently, the dyeing is finished by rinsing, oxidizing with 1.5% potassium bichromate, and 3% of a 30% acetic acid at a temperature of 6070 C again rinsing, soaping, and rinsing once more.
Example 3 A cotton cheese is treated in a circulating bath containing 3% Hydrosol Blue R (C.I. Solubilized Sulfur Blue 7, C.I. No. 53441), and 2% Procion Brillitant-blue MRS (C.I. Reactive Blue 4), 30 g./l. calcined sodium sulfate, and 15 g./l. calcined sodium carbonate during 30 minutes at 30 C.; then 4.5% of a 20% sodium hydrosulfide solution are added, the material is dyed for a further 10 minutes at 30 C. and, after the temperature of the liquor has been raised to 60 C., another 30 minutes at this temperature. Subsequently, the dyeing is rinsed, oxidized at 40 C. with 0.5% of 35% hydrogen peroxide, soaped, and rinsed again. Thus, a deep and brilliant blue dyeing of a good uniformity is obtained.
Example 4 A cheese of mixed cotton-cellulose yarn is first treated in a circulating bath containing 10% Hydrosol Fast Yellow G (C.I. Solubilized Sulfur Yellow 5 being the thiosulfonic acid of C.I. Sulfur Yellow 5, the constitution of which is described in Collection Czechoslov. Chem. Commun., vol. 27 (1962), page 1533/48), 2% Cibacron Turquoise-blue G (C.I. Reactive Blue 7, constitution described in Collection Czechoslov. Chem. Commun., vol 25 (1960), page 2797), 20 g./l. calcined sodium sulfate, 2% sodium sulfhydrate, and g./l. calcined sodium carbonate, during 10 minutes at 30 C. The temperature of the liquor is then increased to 90 C. within 30 minutes, and the material is dyed during 30 minutes at this temperature. Subsequently, the dyeing is finished by rinsing, oxidizing at 40 C. with a liquor containing 1 g./l. sodium perborate, soaping and rinsing. A brilliant green dyeing is, thus, obtained which is impossible to obtain with sulfur dyes only.
Example 5 A cotton cheese is treated in a circulating bath containing 6% Hydrosol Fast Yellow-brown GL (C.I. Solubilized Sulfur Brown 60, Cl. No. 5326), 2% Cibacron Scarlet 2G (C.I. Reactive Red 9, constitution described in Collection Czechoslov. Chem. Commun., vol 25 (1960), page 2794/95), 30 g./l. calcined sodium sulfate, and g./l. calcined sodium carbonate during 60 minutes at 60-65 C. The dye liquor is then cooled down to 30 C., admixed with 2% sodium hydrosulfide, and dyeing is continued for 10 minutes at 30 C. and, after the temperature of the liquor has been raised to 90 C., for another 30 minutes at 90 C. Subsequently, the dyeing is rinsed, oxidized at 40 C. with a liquor containing 1 g./l. sodium perborate, soaped, and rinsed again. Thus, a vivid red brown dyeing is obtained, having a very good uniformity.
