Description

(54) PROCESS FOR DYEING AND PRINTING SHEETS OR SHEET-LIKE STRUCTURES (71) We, BAYER AKTIENGESELLSCHAFT, a body corporate organised under the laws of Germany, of Leverkusen, Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The subject of the invention is a process for dyeing and printing, with disperse dyestuffs, textile sheets or sheet-like structures consisting wholly or partly of fibres containing OH or NH groups.
The process is characterised in that the sheet or sheet-like structure is impregnated or printed with a liquor or printing paste containing a) a fibre-reactive compound (as hereinafter defined) which is at the same time a solvent for disperse dyestuffs, b) an acidic compound which catalyses the reaction and optionally a swelling agent for fibres and optionally a crosslinking agent and c) disperse dyestuffs, and is dried, and the textile sheet or sheet-like structure is then subjected to a heat treatment.
"Fibre-reactive compounds" a) are substances which contain, on the one hand, at least one hydrophobic hydrocarbon radical and, on the other hand, at least one reactive group which enters into a chemical bond with the OH or NH groups of the fibre materials in the presence of the catalyst b) by a condensation reaction, that is to say splitting off, for example, water, alcohol or halogenohydrocarbon.
Suitable hydrocarbon radicals are those which have 6 to 22 C atoms. The radicals can be saturated or unsaturated, straight-chain, branched or cyclic and can be interrupted by hetero-atoms (for example 0 or S) and can also be substituted by substituents (for example C1-C4-alkoxy, phenoxy, phenyl, cyclohexyl, benzyl and halogen, provided that the solvent character of these radicals is not thereby substantially impaired. Suitable reactive groups are the customary groupings which are known from permanent finishing and the chemistry of reactive dyestuffs and which contain at least one radical which can be split off and which is capable of reacting, in the presence of suitable catalysts and optionally under the influence of heat, with the functional groups of the said types of fibre with the formation of a covalent bond.Such groupings are described in large numbers in the literature, for example in "The Chemistry of Synthetic Dyes", volume VI, chapter 1, edited by Venkataraman, and in British Patent Specification 1,378,244, page 1, line 15 to page 3, line 60 (with the exception of the relative groups capable of adding on).
Preferred reactive compounds are formaldehyde derivatives of organic nitrogen compounds, especially those of the formula
wherein R represents an optionally substituted alkyl, alkenyl, cycloalkyl, aryl or aralkyl radical having 6 to 22 C atoms, A represents a direct bond or a divalent bridge member, R' represents hydrogen, an optionally substituted alkyl, alkenyl, aryl, aralkyl or acyl radical or the radical
and R2 represents hydrogen, an optionally substituted alkyl, alkenyl or aralkyl radical, the radical CH2OR' or the radical

The alkyl radicals R can be interrupted by oxygen atoms and substituted by substituents, for example, C1-C18-alkoxy, phenoxy, phenyl, cyclohexyl, benzyl, chlorine, bromine or OH.
The alkenyl radicals R are preferably unsubstituted. Suitable cycloalkyl radicals are cyclohexyl radicals which can be substituted, for example, by C1-C4- alkyl or chlorine.
Suitable aryl and aralkyl radicals R and R' are phenyl and phenyl-C1-C4-alkyl radicals, which can be substituted in the benzene nucleus by C1-C4-alkyl, C1-C4- alkoxy, chlorine, bromine and others.
Suitable alkyl radicals R' and R2 are those which have 1-6 C atoms and which can be interzupted by oxygen bridges and substituted by substituents, for example, OH, Cl, Br, CN,
C1-C4-alkoxy, C1-C4-alkoxycarbonyl or the radicals
wherein V represents H or a cation and Z represents V or C1-C4-alkyl or hydroxy C1-C4-alkyl.

The compounds described in the preceding text are, in part, known or are readily accessible by methods which are in themselves known.The formaldehyde derivatives which are to be used preferentially are obtained, for example, by reacting corresponding compounds containing amino groups (e.g. amides, ureas and urethanes) with formaldehyde in the presence of alkali and optionally by subsequent etherification or esterification, carried out in a customary manner.
Methods of this type are described, for example, in Org. Reactions 14 (1965), pages 52-269, Helv. Chim. Acta 24, (1941), pages 302 et seq., DT-OS (German Published Specification) 2,313,554, U.S. Patent Specification 2,361,185 and 2,313,742.
Suitable catalysts b) are customary substances which split off acid under hot conditions. Suitable catalysts for the reactive compounds of the formula I which are to be employed preferentially are acid donors, such as ammonium chloride, ammonium sulphate, ammonium phosphate or the chlorides, nitrates and perchlorates of magnesium or zinc, aluminium sulphate and sodium dihydrogen phosphate.
Suitable catalysts for reactive compounds which react with the OH or NH groups of the fibres with the elimination of hydrogen halides, are customary alkaline compounds, such as alkali metal hydroxides, carbonates and bicarbonates.
Suitable swelling agents to be employed in accordance with the process are, above all, customary cellulose swelling agents which are not volatile under the conditions of transfer printing or thermofixing.
The following may be mentioned as examples: caprolactam, ethylene glycol, diethylene glycol, dipropylene glycol, butanediol, hexanediol, glycerol, sorbitol, ethylene glycol monomethyl ether, diethylene glycol monomethyl ether, diethylene glycol monobutyl ether, triethylene glycol, pentaglycol, butanediol, ethylene glycol monoacetates, acetic acid glycerol esters, diethylene glycol monomethyl etheracetate, polyethylene oxides and polypropylene oxides having molecular weights of 200 to 1,000, oxyethylated nonylphenol or polyethers in accordance with British Patent Specification 1,249,896 (DOS (German Published Specification) 1,811,796) of the general formula
wherein n=0 or 1, m=2 to 20, R=H, alkyl, aralkyl, alkaryl, -COR2, SO2R2 or CO2R2, R2=alkyl, cycloalkyl, aralkyl or aryl, R1=OH, OR2, SR2, NHR2, OCOR2, OSO2R2 and NH-aryl, x=the number of unsaturated valencies in A and A=ROCH2CHORCH2, CH2-CHORCH2-(CH2)4C and CH2C(CH2OR)2.
The quantity to be employed depends on the substrate to be dyed, the nature of the dyestuff and so on, and must be determined in an individual case by simple preliminary tests.
Phosphoric acid alkyl esters, such as dibutyl phosphate, are also very suitable as swelling agents.
Suitable crosslinking agents for improving the creasing behaviour are reactant resins, melamine resins and also urea-formaldehyde resins, for example, the following substances: dimethylolurea, dimethylolethyleneurea, dimethylolpropyleneurea, dimethyloldihydroxyethyleneurea, trimethylolmelamine, trimethoxymethylmelamine, hexamethoxymethylmelamine, dimethylolhydroxyethyltriazone, dimethylolmethyl-carbamate, dimethylolethyl-carb amate, dimethylolhydroxyethyl-carbamate, N-methylolacrylamide, glyoxal, tetraoxane, chloral hydrate, glutaraldehyde and epichlorohydrin.
Water-soluble, masked isocyanates, especially bisulphite adducts of customary isocyanates, such as are described, for example, in Liebigs Annalen, volume 562.
page 205 et seq.: Anew. Chemie, volume 49, page 257 et seq. and German Patent Specification .859,156, are also suitable.
It is preferable to use the bisulphite adducts in the form of their aqueous or aqueous-organic solutions which are stable on storage and which contain, in accordance with DT-OS (German Published Specification) 2,414,470, 0.5 to 20 per cent by weight (relative to the bisulphite adduct) of an aromatic sulphonic acid (preferably toluenesulphonic acid).
Textile sheets or sheet-like structures such as woven fabrics, knitted fabrics, non-wovens, sheets and carpets, are suitable for the process according to the invention.
Preferred fibre materials are those consisting of cellulose fibres, for example, cotton, staple rayon, linen, jute and hemp, as well as natural polyamides, such as wool, silk and leather.
Synthetic polyamides are also suitable for the process according to the invention, as are mixed structures of the fibre materials previously mentioned with materials composed of cellulose esters, polyurethanes, polyamides, polyacrylonitrile and particularly aromatic polyesters.
The reactive substances according to the invention are applied in quantities of 1-10%, preferably in quantities of 26%, relative to the textile material.
The quantity of the catalysts to be employed can be 0.510%, preferably 58%, relative to the reactive substances.
The quantities of swelling agent added can vary, depending on the nature of the textile material. They amount to 15%, preferably 23%, relative to the textile material. The quantity of crosslinking agents added to improve the creasing behaviour can vary within wide limits depending on the effects desired. The quantities can be 214%, preferably 38%, relative to the substrate.
The substances previously mentioned are preferably applied to the textile material from an aqueous medium, whilst adding disperse dyestuffs, but they can also be applied from organic solvents, for example perchloroethylene.
Unless the fibre-reactive compounds possess groups which impart solubility, they are preferably employed, for the preparation of the aqueous liquors, together with 1--20 (relative to fibre-reactive compounds), especially with 510%, of a customary anionic, cationic, non-ionic and/or amphoteric emulsifying or dispersing agent. In addition, it is also possible to add further auxiliaries, such as solubilisers or thickening agents to the liquors.
Catalysts which split off acid under hot conditions, and disperse dyestuffs are also added to the liquors. The liquors can be applied to the textile material by dipping and squeezing out, by spraying or by slop-padding on one or both sides.
In carrying out the process in practice, the procedure followed is, for example, to apply the liquors according to the invention to the textile by means of a padder.
The textile is then dried at 80-130 C, preferably at 120-130 C, for example in a stenter frame, and subsequently heated at 140-220 C. For textiles which consist only of cellulose, the subsequent heating can be carried out for 4-5 minutes at 140-170 C, preferably et 160 C. For mixed fabrics consisting of fibres containing cellulose and synthetics, for example a textile material consisting of cotton and polyester fibres, the heat treatment is appropriately carried out for 30-45 seconds at 20W220 C, preferably at 2100C. For light-weight goods a so-called shock condensation is also possible. The textile which has been treated with the liquors according to the invention is subjected to a heat treatment at 210-220 C for 60-90 seconds.In the course thereof the textile material dries and the substances according to the invention and the disperse dyestuffs become fixed.
For the production of prints, the fibre-reactive substances are emulsified in water together with the emulsifiers previously mentioned. Thickening agents which are customary in printing, for example those based on methylcellulose, sodium alginate or commercially available starch ethers, are added to the emulsions.
Disperse dyestuffs as well as agents which split off acid and optionally further crosslinking agents can now be added to the resulting pastes.
The sheet-like structures are printed with the printing pastes according to the invention in a customary manner, for example by the silk-screen printing process, the roller printing process or the spray printing process.
The printed textile material is dried as described above and is then subjected to a heat treatment.
Dyestuffs which can be used for dyeing and printing are commercially available disperse dyestuffs, the dyestuffs which are suitable for the thermosol process being preferred for mixed fabrics, for example fabrics consisting of cotton and polyester fibres.
The process according to the invention, which has been described, makes it possible preferentially to dye and print polyester/cellulose mixed fabrics with only one category of dyestuffs, with high tinctorial strengths.
Excellent tone-in-tone dyeings or prints of good fastness properties to use are produced.
The sheets or sheet-like structures which have been printed or dyed by the process according to the invention have attractive characteristics of handle and good creasing behaviour.
