EP0877116A2 - Alkali system for pad dyeing cellulosic textiles - Google Patents

Abstract

An inorganic polyphosphate is advantageously used instead of water glass as an alkali system in padding or spraying processes for dyeing cellulosic textiles used.

Description

Cellulosic textiles can be dyed using the pull-out or block method or by printing on textiles. The reactive dyes are of particular importance here, being able to form a covalent bond with the fiber during the dyeing process. Particularly noteworthy is the good wet fastness level of the reactive dyes, which other dye classes cannot achieve or only with difficulty.
However, reactive dyes can generally only form a covalent bond if the dyeing process has been carried out under alkaline conditions. Carbonates, hydrogen carbonates, hydroxides and, above all, silicates in block dyeing are used as alkali donors. The auxiliary chemicals are used as pure substances or as mixtures. Carbonates / hydroxide mixtures in particular are highly efficient and are preferably used. As a rule, the alkali system is matched to the respective reaction anchor of the reactive dye and the special dyeing process.

In the dyeing industry, "padding" means applying a treatment liquor to a textile web and then squeezing off excess liquor. In this context, a distinction is made between two order processes, namely the one- and two-step processes.
Two-stage processes always have the disadvantage of complex mechanical use and the use of salt in the second process stage. After impregnation of the web with a dye solution in a first step, the material is run into so-called "boosters" (second stage), in which the goods are loaded with an alkaline salt liquor (alkali and electrolyte salts).
In contrast, the entire treatment liquor, which typically contains the reactive dye, alkali-donating agents and optionally detergents, is applied to the goods in a single step before the fixing step.

Silicate in the form of water glass (Na ₂ O: SiO ₂ , ratio 1: 2 to 1: 3.5) is very often used as an alkali-donating agent in block-cold dwellings, primarily for reactive dyes containing vinyl sulfone. The dye liquor also contains between 6 and 40 ml / l sodium hydroxide solution (32.5% by weight). Water glass has a pH-buffering effect and increases the so-called pad liquor stability of reactive dyes. In this context, the edge protection of the docked goods against carbon dioxide in the circulating air must be mentioned as a positive effect.
However, the use of water glass does not only offer advantages. It is disadvantageous that water glass has a strong tendency to crystallize (soiling of the machines) and there is no possibility of neutralization before the washing process, that use in "steam processes" is not possible without restrictions and that in some cases unsightly handle effects also occur.

The invention was therefore based on the desire for an alkali system that Avoids disadvantages described above.

The US-PS 4,555,348 describes a liquid buffer system made of trisodium or Tripotassium phosphate and sodium hydroxide solution with pH values between 11 and 13 should be suitable as an addition to pull-out dye baths.

It has been found to replace silicates in block processes Surprisingly, low molecular weight and high molecular weight polyphosphates are used can. The low molecular weight metapolyphosphates are also for this Suitable for use. This effect is particularly surprising because because the salts of polyphosphoric acids dissolve with a neutral pH.

The present invention therefore relates to a process for dyeing cellulosic textiles according to a block process or spray process, thereby characterized in that the dye liquor or spray solution 5 to 100 g / l, preferably 7th contains up to 40 g / l, in particular 10 to 20 g / l, of an inorganic polyphosphate and has a pH of 10 to 13.5, preferably 11 to 13.

Inorganic polyphosphates are generally understood to mean the salts of polyphosphoric acids which result from these through condensation processes. A distinction is made in the case of the condensed phosphoric acids between linear polyphosphoric acids H _{n + 2} P _n O _{3n + 1} and cyclic metapolyphosphoric acids H _n P _n O _3n which arise from the former by ring closure and H ₂ O elimination and can be converted back into them by hydrolysis . While the number n of phosphorus atoms in the ring-shaped metapolyphosphoric acids and their salts is relatively small (n = 3-8), they can grow to much larger values in the open-chain polyphosphoric acids and their salts. Low molecular weight polyphosphates M _{n + 2} P _n O _{3n + 1} (with n = 2-10) and high molecular weight polyphosphates M _n H ₂ P _n O _{3n + 1} (with n = 11-90) are known, in which two terminal hydrogen atoms, which have only a very low acid character, are not replaced by metal atoms and whose composition is very close to that of the formula M _n P _n O _3n of metaphosphates. M each represents an alkali metal, for example Na or K.

The low molecular weight polyphosphates M _{n + 2} P _n O _{3n + 1} are generally obtained by dewatering a mixture of primary and secondary monophosphates in different molar ratios and at different temperatures. Examples include the five-base triphosphoric acid H ₅ P ₃ O ₁₀ and the six-base tetra-phosphoric acid H ₆ P ₄ O ₁₃ and their salts. These phosphates are already used today as water softeners. The cyclic metapolyphosphates M _n P _n O _3n are generally formed when primary monophosphates are heated by way of polyphosphates M _n H ₂ P _n O _{3n + 1} by ring closure with the escape of water.
Among the high molecular weight polyphosphates of the formula Na _n H ₂ P _n O _{3n + 1} , mention should be made of "Graham's salt", "Maddrell's salt" and "Kurrol's salts". The "Graham salt" is created by heating NaH ₂ PO ₄ to over 600 ° C and consists of chains of 30 to 90 phosphorus atoms.

The preparation of the various polyphosphates is familiar to the person skilled in the art and can be found in the literature.

The polyphosphates can be used either as solids directly or in the form of their solutions be added to the water of the dye liquor. Mixtures of the above Polyphosphates can be used. To set the required pH an appropriate amount of alkali, e.g. Caustic soda or soda, the Dye bath can be added.

The polyphosphates can be used in all padding processes instead of silicates Alkaline dispensers or pH buffering substances can be used. To this Processes include the block-cold dwell process known to those skilled in the art Pad-Dry-Pad-Steam process, the Pad / Air-Steam process and the Thermosol / pad steam process.

In the pad-dry-pad-steam process, the fabric to be dyed is after Pad dry the dye between, then the alkaline Padded brine and then at steam temperatures of about 100 to 103 ° C the reactive dye fixed.

In the pad / air steam process, the alkaline dye liquor is padded and 2 to 3 minutes at about 120 ° C and a wet temperature of the goods of about 70 ° C with dampened by a humidity of about 20%.

With the Thermosol / Pad-Steam process (for mixed items, e.g. polyester / cotton) a disperse and reactive dye is first padded and at about 120 ° C dried. Then heat-set at about 180 ° C and then block one alkaline salt liquor. There follows an approximately 1 minute steaming process at approximately 102 ° C.

The spraying process is a non-contact application technique for the dyeing liquor understood, for example an ink jet process.

The method according to the invention is particularly suitable for dyeing with suitable for fiber-reactive dyes.

Fiber-reactive dyes are organic dyes which contain 1, 2, 3 or 4 fiber-reactive radicals from the aliphatic, aromatic or heterocyclic series. Such dyes have been extensively described in the literature. The dyes can belong to a wide variety of dye classes, for example the class of monoazo, disazo, polyazo, metal complex azo, such as 1: 1 copper, 1: 2 chromium and 1: 2 cobalt complex monoazo. and disazo dyes, further the series of anthraquinone dyes, copper, nickel and cobalt phthalocyanine dyes, copper formazan dyes, azomethine, nitroaryl, dioxazine, triphendioxazine, phenazine and stilbene dyes. Fiber-reactive dyes are understood to mean those which have a “fiber-reactive” group, ie a group which is able to react with the hydroxyl groups of cellulose or with the amino and possibly carboxy groups of polyamides to form covalent chemical bonds. The fiber-reactive residue can be bound to the dye residue directly or via a bridge member; it is preferably directly or via an optionally monoalkylated amino group, such as, for example, a group of the formula -NH-, -N (CH ₃ ) -, -N (C ₂ H ₅ ) - or -N (C ₃ H ₇ ) -, or via an aliphatic radical, such as a methylene, ethylene or propylene radical or an alkylene radical of 2 to 8 carbon atoms, which can be interrupted by one or two oxy and / or amino groups, or via a bridge member containing an amino group, such as a phenylamino group, attached to the dye residue.

Fiber-reactive radicals are, for example: vinylsulfonyl, β-chloroethylsulfonyl, β-sulfatoethylsulfonyl, β-acetoxy-ethylsulfonyl, β-phosphatoethylsulfonyl, β-thiosulfatoethylsulfonyl, N-methyl-N- (β-sulfatoethyl-sulfonyl) -amino, acryloyl, -CO- CCl = CH ₂ , -CO-CH = CH-Cl, -CO-CCl = CHCl, -CO-CCl = CH-CH ₃ , -CO-CBr = CH ₂ , -CO-CH = CH-Br, -CO -CBr = CH-CH ₃ , -CO-CCl = CH-COOH, -CO-CH = CCl-COOH, -CO-CBr = CH-COOH, -CO-CH = CBr-COOH, -CO-CCl = CCl -COOH, -CO-CBr = CBr-COOH, β-chloro- or β-bromopropionyl, 3-phenylsulfonylpropionyl, 3-methylsulfonylpropionyl, 3-chloro-3-phenylsulfonylpropionyl, 2,3-dichloropropionyl, 2,3-dibromopropionyl, 2 -Fluoro-2-chloro-3,3-difluorocyclobutane-2-carbonyl, 2,2,3,3-tetrafluorocyclobutane-1-carbonyl or -1-sulfonyl, β- (2,2,3,3-tetrafluorocyclobutyl-1 ) acryloyl, α- or β-methylsulfonylacryloyl, propiolyl, chloroacetyl, bromoacetyl, 4- (β-chloroethylsulfonyl) butyril, 4-vinylsulfonylbutyryl, 5- (β-chloroethylsulfonyl) valeryl, 5-vinylsulfonylvaleryl , 6- (β-chloroethylsulfonyl) caproyl, 6-vinylsulfonyl-caproyl, 4-fluoro-3-nitro-benzoyl, 4-fluoro-3-nitrophenylsulfonyl, 4-fluoro-3-methyl-sulfonylbenzoyl, 4-fluoro-3-cyano-benzoyl, 2-fluoro-5- methylsulfonyl-benzoyl, 2,4-dichlorotriazinyl-6, 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-methylsulfonyl-pyrimidinyl-6, 2,5-dichloro-4 -methylsulfonyl-pyrimidinyl-6, 2-fluoro-4-pyrimidinyl, 2,6-difluoro-4-pyrimidinyl, 2,6-difluoro-5-chloro-4-pyrimidinyl, 2-fluoro-5,6-dichloro-4 -pyrimidinyl, 2,6-difluoro-5-methyl-4-pyrimidinyl, 2,5-difluoro-6-methyl-4-pyrimidinyl, 2-fluoro-5-methyl-6-chloro-4-pyrimidinyl, 2-fluorine -5-nitro-6-chloro-4-pyrimidinyl, 5-bromo-2-fluoro-4-pyrimidinyl, 2-fluoro-5-cyano-4-pyrimidinyl, 2-fluoro-5-methyl-4-pyrimidinyl, 2 , 5,6-trifluoro-4-pyrimidinyl, 5-chloro-6-chloromethyl-2-fluoro-4-pyrimidinyl, 2,6-difluoro-5-bromo-4-pyrimidinyl, 2-fluoro-5-bromo-6 -chloromethyl-4-pyrim idinyl, 2,6-difluoro-5-chloromethyl-4-pyrimidinyl, 2,6-difluoro-5-nitro-4-pyrimidinyl, 2-fluoro-6-methyl-4-pyrimidinyl, 2-fluoro-5-chloro 6-methyl-4-pyrimidinyl, 2-fluoro-5-chloro-4-pyrimidinyl, 2-fluoro-6-chloro-4-pyrimidinyl, 6-trifluoromethyl-5-chloro-2-fluoro-4-pyrimidinyl, 6- Trifluoromethyl-2-fluoro-4-pyrimidinyl, 6-trifluoromethyl-2-fluoro-4-pyrimidinyl, 2-fluoro-5-nitro-4-pyrimidinyl, 2-fluoro-5-trifluoromethyl-4-pyrimidinyl, 2-fluoro 5-phenyl or -5-methylsulfonyl-4-pyrimidinyl, 2-fluoro-5-carbonamido-4-pyrimidinyl, 2-fluoro-5-carbomethoxy-4-pyrimidinyl, 2-fluoro-5-bromo-6-trifluoromethyl-4 -pyrimidinyl, 2-fluoro-6-carbonamido-4-pyrimidinyl, 2-fluoro-6-carbomethoxy-4-pyrimidinyl, 2-fluoro-6-phenyl-4-pyrimidinyl, 2-fluoro-6-cyan-4-pyrimidinyl , 2,6-difluoro-5-methylsulfonyl-4-pyrimidinyl, 2-fluoro-5-sulfonamido-4-pyrimidinyl, 2-fluoro-5-chloro-6-carbomethoxy-4-pyrimidinyl, 2,6-difluoro-5 -trifluoromethyl-4-pyrimidinyl, 2,4-bis (methylsulfonyl) pyrimidinyl-4, 2,5-bis (methylsulfonyl) -5-chloropyrimidinyl-4, 2-methyls sulfonylpyrimidinyl-4, 2-phenylsulfonyl-pyrimidinyl-4, 2-methylsulfonyl-5-chloro-6-methyl-pyrimidinyl-4, 2-methylsulfonyl-5-bromo-6-methylpyrimidinyl-4, 2-methylsulfonyl-5-chloro 6-ethyl-pyrimidinyl-4, 2-methylsulfonyl-5-chloromethyl-pyrimidinyl-4, 2-methylsulfonyl-5-nitro-6-methyl-pyrimidinyl-4, 2,5,6-tris-methylsulfonyl-pyrimidinyl- 4, 2-Methylsulfonyl-5,6-dimethyl-pyrimidinyl-4, 2-ethylsulfonyl-5-chloro-6-methylpyrimidinyl-4, 2-methylsulfonyl-6-chloropyrimidinyl-4, 2,6-bis (methylsulfonyl) -
