Definitions
- the present invention relates to a novel process for dyeing textile cellulosic fibers with vat dyes, sulfur dyes, leuco vat ester dyes or azo development dyes using the padding process.
- the foulard process is a dyeing process known for cellulose fibers, which allows large amounts of textile fiber materials to be dyed and soaked by impregnating or impregnating the fiber with the dye solution in a trough with the shortest liquor ratio and usually only once passing through the foulard with a short dyeing time then fix it.
- Tailing / reverse tailing is the difference in strength and nuance between the beginning and end of a game. When only one dye is used, the end unevenness is noticeable in differences in strength, while shades in the shade can often also occur with combination dyeings.
- Tailing is a weakening of the color strength between the beginning and end of the batch, which is due to a decrease in the dye concentration in the trough. This depletion of the dye in the liquor is caused by drawing up the dye in the padding process caused. Differences in strength and shade based on tailing occur particularly in the case of dyes with medium to high substantivity and very particularly often when coloring light shades.
- Reverse tailing is an increase in color strength between the beginning and end of the batch, which is due to the increase in the dye concentration in the trough. This dye accumulation in the padding liquor is caused by a preferred water adsorption in the padding process. Differences in strength and shade based on reverse tailing occur with dyes of low substantivity, especially when coloring dark shades.
- the azine compounds of formula (1) are preferred.
- the colorless nitrogen-containing compound of formula (1) or (2) used in the process according to the invention is water-soluble and has substantivity for cellulose fibers, i.e. it is fiber-affine.
- the amount of the fiber-affine compound in the processes according to the invention depends in particular on the amount of dye used, a minimum amount of 0.5 g / l and generally from 0.5 to 20 g / l, preferably 3 g / l to 10 g / l has proven to be very beneficial.
- the fiber-affine compound contains 1 to 6, expediently 1 to 4, acidic water-solubilizing groups, which are in particular carboxyl groups or especially sulfonic acid groups.

- V is preferably R2-X2 ⁇ and W is especially R3-X3 ⁇ .
- Azine compounds of the formula (1) in which X1, X2 and X3 each represent ⁇ NH- are particularly preferred.
- aryl radical such as e.g. is a naphthyl or especially a phenyl radical.
- V R2-X2 ⁇ and W are hydroxyl.
- triazine compounds of the formula (5) in which X1, X2 and X3 each have ⁇ NH ⁇ , R1, R2 and R3, independently of one another, each phenyl or naphthyl, Z is the sulfonic acid group and m 2 to 4, preferably 2 or 3 mean.
- triazine compounds of formula (6) in which V 'R2-X2 ⁇ and W' are hydroxyl.
- colorless nitrogen-containing compounds which can be used according to the invention are and
- Suitable cellulose fibers are natural fibers, such as mercerized or bleached cotton and linen (bleached), and regenerated fibers, such as viscose, rayon, polynosic and copper rayon. Mainly woven or knitted fabrics made of these fibers, especially cotton.
- Fiber blends e.g. those made of polyester / cotton, the polyester portion being colored with disperse dyes, can also be used.
- Suitable dyestuffs which can be used in the process according to the invention are the dyestuffs of the type mentioned which are customarily used for dyeing or printing cellulose textile materials.
- the leuco vat ester dyes are e.g. from vat dyes of the indigo, anthraquinone or indanthrene series by reduction e.g. with iron powder and subsequent esterification e.g. available with chlorosulfonic acid and are referred to in the Color Index 3rd Edition, 1971, Vol. 3 as "Solubilized Vat Dyes".
- vat dyes are, for example, higher fused and heterocyclic benzoquinones or naphthoquinones, in particular anthraquinone or indigoid dyes, especially sulfur dyes.
- vat dyes which can be used according to the invention are listed in the Color Index 3rd Edition (1971) Vol. 3 on pages 3649 to 3837 under the names "Sulfur Dyes” and "Vat Dyes”.
- the components for the azo development dyes are the color index 3rd edition 1971 as Azoic Coupling Components ("Naphthole”) and the chemical compounds listed as Azoic Diazo Components.
- the amount of dyes in the process according to the invention generally depends on the desired color strength, with end unevenness especially in the case of light shades, i.e. at a concentration of 0.03 g / l to 10 g / l, preferably 0.05 to 6 g / l.
- a particularly preferred embodiment of the process according to the invention consists in that an aqueous dye liquor is used which contains 1 to 6 g / l of dye and 3 to 10 g / l of azine compound.
- the term g / l means grams per liter. For dyes, it refers to 100% powder trading form.
- the dyeing liquors can contain other conventional additives in addition to the colorless compound, e.g. Alkali such as sodium carbonate, sodium bicarbonate, sodium hydroxide, potassium hydroxide, trisodium phosphate, borax, aqueous ammonia, or alkali dispensers such as e.g. Sodium formate or sodium trichloroacetate, electrolytes such as e.g. Contain sodium chloride or sodium sulfate as well as urea, thiourea or glycerin.

- the amounts in which the wetting agents are added to the dyeing liquor are more appropriately between 0.2 to 10 g, preferably 0.5 to 3 g, per liter of liquor.
- the dye fixation on pure cellulose fibers is carried out by customary methods, the fixing time and fixing temperature depending on the fiber material and on the dye. Steaming times in saturated steam between 30 seconds and 5 minutes at 100 to 105 ° C. are generally sufficient to achieve a uniform and optimal dye fixation. High-temperature steaming or dry heat steaming is used to fix at 105-190 ° C for 20 seconds to 3 minutes. In particular, the dyes are fixed with steam at a temperature of 100 ° C to 120 ° C for 30 seconds to 3 minutes. If necessary, the textile material is dried before fixing.
- fixation can also be carried out by the cold dwell process, such as 6 to 24 hours residence time at room temperature.
- the dyed cellulose material can be washed out in a conventional manner in order to remove unfixed dye.
- the substrate is treated, for example, at from 40 ° C. to cooking temperature in a solution which contains soap or synthetic detergent. Treatment with a fixative can then be carried out to improve wet fastness.
- the dyeings are completed by rinsing in hot and / or cold water and, if appropriate, with subsequent washing in the presence of a commercially available detergent, followed by rinsing in water and drying.
- the dive time is 3 seconds.
- the fabric is steamed at 101-103 ° C for one minute and rinsed with water at 25 ° C.
- the dyeing is then oxidized with 5 ml of hydrogen peroxide for 2 minutes at 70 ° C., then soaped and rinsed hot and cold.
- a cotton cord fabric dyed in the same shade of red with very good fastness properties is obtained.
- Example 1 If one proceeds as described in Example 1, but uses a liquor without the triazine compound of the formula (8), a cotton cord fabric dyed in a different shade of red is obtained, the beginning of the lot being darker in color compared to the end of the lot, because the squeezed liquor is depleted of dye and thus diluted.
- the dyeing is treated with saturated steam at 101 ° C for 90 seconds and rinsed cold, then the dyeing is oxidized at 70 ° C for 60 seconds with 7 ml / l hydrogen peroxide, boiling soaped with 1 g / l detergent, hot and rinsed cold and dried.
- the fabric is rinsed cold, neutralized with an aqueous solution containing 2 g / l sodium carbonate, soaped at the boil, rinsed hot and cold and finally dried.
- a cotton fabric dyed in the same shade of blue with very good fastness properties is obtained.
- the cotton cretonne fabric After 30 seconds of air, the cotton cretonne fabric is dried in a hot flue at 120 ° C. for 45 seconds. The color is then developed by impregnation on the pad with a squeezing effect of 80% liquor absorption with an aqueous liquor which contains 13 g / l of an Azoic Diazo Component 1 with a CI No. 37135. The dive time is 6 seconds. After passing the development pad, there is an air passage of 30 seconds. The cotton cretonne fabric is then rinsed with water at 70 ° C., soaped at the boil with 2 g / l detergent, rinsed hot and cold and dried.
- the fabric is rinsed cold, neutralized with an aqueous solution containing 2 g / l sodium carbonate, soaped at the boil, rinsed hot and cold and finally dried.
