- a temperature between 100 ° and 220 ° C., in particular 100 ° to 105 ° C. or 150 ° to 190 ° C., based on a pressure of 1 bar, has been found to be particularly advantageous for fixing in a hot steam atmosphere proven.
- a particularly preferred embodiment of the method according to the invention is characterized in that printed textile materials are used, in particular those which are printed with printing pastes containing a thickener that promotes reduction.
- printed textile materials with dye mixtures containing at least one water-soluble reactive dye and at least one disperse dye are used in the process according to the invention as printed textile materials from blended fabrics, in particular printed polyester / cellulose blended fabrics and, above all, printed cellulose fibers.
- a polyester / cellulose blend fabric which is printed with a printing paste containing at least one water-soluble reactive dye, at least one disperse dye, alginate and fixing alkali is very particularly preferably used as the printed textile material made of polyester / cellulose blend fabric. and above all a polyester / cellulose blended fabric is used which is printed with a printing paste containing at least one fiber-reactive, sulfo-containing azo or metal complex azo dye, at least one azo dispersion dye, alginate and a fixing alkali and in a water vapor atmosphere under normal pressure at 150 ° to 220 ° is fixed, which contains 1.5 to 3.5 percent by volume of air.
- Textile materials are those made from natural and synthetic fibers and mixtures thereof. Examples include: cotton, linen (bleached), viscose, polynosic, copper synthetic silk, wool, silk, synthetic polyamide, polyester and polyurethane fibers, wool / polyamide, wool / polyester, wool / cellulose, wool / Polyacrylonitrile and polyester / cellulose blended fabrics.
- Synthetic polyamide, polyester, cellulose fibers and polyester / cellulose blended fabrics are preferably used as textile materials.
- the textile materials are dyed or printed by methods known per se, dried and then fixed in accordance with the method according to the invention.
- the fixation takes place in one of the conventional continuous or discontinuous dampers known per se, which must have a device for the targeted addition of air.
- the air inlet can be regulated, for example, via a valve.
- the water vapor state in the process according to the invention corresponds to the steam state customary in industrial dampers, such as Saturated steam and superheated steam.
- Steaming time and steam temperature depend on the dyes and textile material used.
- textile materials are used which are dyed or printed with azo, metal complex azo and metallized formazan dyes.
- These dyes can be water-soluble or water-insoluble.
- Suitable disperse dyes come e.g. B. the dyes known from the Color Index as Disperse Dyes.
- the radical Q 1 is especially a radical of the benzene series, such as phenyl or sulfophenyl, or an alkyl radical, such as. B. methyl, a low molecular weight alkanoyl group, such as. B. Actyl, a carbalkoxy group having up to 4 carbon atoms, a benzoyl group or a heterocyclic radical, and A and B are preferably phenyl radicals substituted by sulfo, sulfonamido or alkylsulfonyl groups.
- Y 1 and Y 2 are mainly OH and COOH groups. Suitable heavy metals are copper, chromium, cobalt and nickel.
- Cellulose fibers printed with fiber-reactive azo dyes are preferably fixed according to the inventive method; printed polyester / cellulose blended fabrics are also preferably fixed with dye mixtures containing at least one fiber-reactive azo dye and at least one dispersion azo dye.
- Fiber-reactive radicals X are to be understood as those which react with the hydroxyl groups of cellulose, the amino, carboxy, hydroxyl and thiol groups in wool and silk, or with the amino and possibly carboxy groups of synthetic polyamides to form covalent chemical bonds capital.
- X is preferably a fiber-reactive radical of the aliphatic, aromatic or heterocyclic series which is bonded to the radical D directly or via a bridge member.
- X is preferably directly or via an optionally monoalkylated amino group, such as, for example, -NH-, -N (CH 3 ) -, -N (C 2 H 5 ) - or -N (C 3 H 7 ) - or via a bridge member containing an amino group bound to the radical D, where D is an azo, metal complex azo or metallized formazan dye.
- an optionally monoalkylated amino group such as, for example, -NH-, -N (CH 3 ) -, -N (C 2 H 5 ) - or -N (C 3 H 7 ) - or via a bridge member containing an amino group bound to the radical D, where D is an azo, metal complex azo or metallized formazan dye.
- fiber-reactive radicals X of the heterocyclic series are to be mentioned, such as. B. 2,4-dichlorotriazinyl-6, mono-, di- or trihalopyrimidinyl residues, such as 2,4-dichloropyrimidinyl-6, 2,4,5-trichloropyrimidinyl-6-, 2,4-dichloro-5- nitro- or 5-methyl- or -5-carboxymethyl- or -5-carboxy- or -5-cyano- or -5-vinyl- or -5-sulfo- or -5-mono-, -di or trichloromethyl- or 5-methylsulfonylpyrimidinyl-6-, 2,5-dichloro-4-methylsufonyl-pyrimidinyl-6-, 2-fluoro-4-pyrimidinyl-, 2,6-difluoro-4-pyrimidinyl-, 2,6-difluoro -5-chloro-4-pyrimi
- Azo, metal complex azo or metallized formazan dyes which dyed or printed on textile materials in conventional dampers with an air content of less than 0.3 percent by volume to at least 1% during the fixing process are particularly suitable as strongly reduction-sensitive dyes.
- a major advantage of the method according to the invention is that both with continuous and discontinuous steam fixation there are no nuance fluctuations and a consistently high yield of the dyes used is ensured. This advantage is particularly important for light shades, i. H. Textile materials that are dyed or printed with less than 0.5% dye based on the fiber weight.
- Another advantage of the method according to the invention is that textile materials can be used which are printed with printing pastes which contain thickeners with a reducing property.
- a damping chamber for fixing dyed or printed textile materials in a hot steam atmosphere serves as a means for carrying out the method according to the invention, the damping chamber containing a device for admixing air.
- a valve for example, can be used as a device for adding air.
- the air is preferably added to the water vapor via a valve that can be regulated from the outside by a nozzle system.
- DE-A-1 460 356 describes a process which differs in a characteristic manner from the process according to the invention in that the fiber material is first dried in a steam-air mixture and then treated in the presence of pure superheated steam.
- the following examples serve to illustrate the invention.
- the parts are parts by weight and the percentages are percentages by weight.
- the temperatures are given in degrees Celsius.
- the relationship between parts by weight and parts by volume is the same as that between grams and cubic centimeters.
- This printing paste is used to print a cotton fabric in a conventional manner (flat or rotary film printing or Rouleaux printing) and then drying it.
- the printed fabric is steamed for 8 minutes in a water vapor atmosphere without excess pressure (- 1 bar) at 100-102 ° C.
- This water vapor contains 1.5-2% by volume of air.
- the resulting prints have a blue-gray shade after their usual post-washing treatment.
- saturated steam means a saturated water vapor atmosphere at 100 to 102 ° C, which contains 1.5 to 2 percent by volume of air.
- Example 7 A printing paste is prepared according to the following recipe: 1.5 g of the dye of the formula
- This printing paste is used to print a knitted fabric made of synthetic polyamide in a conventional manner and then drying it.
- the printed knitted fabric is fixed for 40 minutes in a water vapor atmosphere without excess pressure (- 1 bar) at 100-102 ° C and an air content of 1.5 to 2 percent by volume. The result is a level, level-stable print.
- Example 8 A printing paste is prepared according to the following recipe: 1.5 g of the dye of the formula
- This printing paste is used to print a knitted fabric made of synthetic polyamide in a conventional manner and then drying it. To the fixie The printed knitted fabric is fixed for 40 minutes in a water vapor atmosphere without excess pressure (- 1 bar) at 100 -102 ° C and an air content of 1.5 to 2 percent by volume. The result is a level, level-stable print.
- the unfixed portion of the dye is removed by repeated cold and warm rinsing. A level print of gray-blue stable, reproducible shade is obtained.
