Process for dyeing textile materials

The invention relates to a method for dyeing textile materials, especially a. Proceed s for Färbsii τοπ natural or regenerated ceilulose textile fibers, except Cellulose esters with polyester textile fibers other than Cellulose acetate, butyrate and propionate are mixed.

The inventive method is particularly favorable for Production of wet-fast dyeings on textile materials, the natural or regenerated cellulose textile fibers, except Cellulose esters mixed with polyester textile fibers, except Cellulose acetate butyrate and propionate contain, whereby on .these textile materials an aqueous dye mass on · - * is brought, which consists essentially of water, a finely divided Suspension - a disperse dye, a disperser * -

A method for dyeing cellulose and polyester textile fibers has already been proposed, a mixture of a dye mass being applied to this, which consists of water, a thiosulfuric acid derivative of a sulfur dye, a disperse dye and a fixing agent such as thiourea or urea, whereupon is dried and fixed by means of an elevated temperature. In this proposed method, some difficulties arise because, for _e B "a) the accessibility and the cost is more expensive of the fixing means far more cumbersome or" as in the present process, b) the fixing agent in the heating a degree of chemical attack with a Show number of disperse dyes, which results in a lower color yield than in the present process with these dis-

Persfarbstoffen results, c) the thiosulfuric acid derivatives the sulfur dyes in the proposed method are strongly related to the polyester fibers as well as to the cellulose fibers fix, while in the present process the thiosulfuric acid derivatives of the sulfur dyes do not fix on the polyester fibers and d) with the proposed one Process results in more damage to the cellulose fibers than it does. in the present proceedings the Pail is.

The following is a detailed description of the invention Procedure given.

The method according to the invention is particularly advantageous insofar as it can be carried out quickly, economically and continuously and see wet-fast dyeings with excellent results In addition, there is no decomposition of the disperse dyes and there is heating of cellulose fibers to a high temperature in the presence of a fixative is avoided, "the Damage or deterioration of cellulose fibers up to lowered to such a level that they are almost as avoided must be designated. The cellulose and polyester fibers can be colored with substantially the same color or different colors as desired,

0098 38/198

by adding a thiosulfate dye of the desired shade for the cellulose fibers and a disperse dye of the desired shade Shade chosen for the polyester fibers

The method of the invention is particularly useful for woven fabrics General cargo suitable, although it is also possible with a number of pastes of forms, for example knitted or hosiery goods, non-woven cloths and strands or nonwovens of yarns can be. ■

The textile fibers used for dyeing by means of the present Process suitable include natural or regenerated Cellulose fibers, with the exception of cellulose esters, which are made with polyester textile fibers, ' except for cellulose acetate, butyrate and propionate, are mixed.

Natural cellulose fibers are suitable for the present use and include, but are not limited to, Cotton and linen.

Regenerated cellulose fibers, other than cellulose esters, are suitable for use herein and include, but are not limited to, copper ammonium rayon, viscose rayon, and the rayons with a high moisture modulus sold under the names "Fiber 40"("Avril"),"Moynel""and ^tt Zantrel" are available, and generally as polynosisehe Rayons (poly-

contain water-soluble organic thiosulphate dyes, migration inhibitors such as sodium alginate, and Na Cl »

Water-soluble organic dyes with at least one thiosulf a tgruppe per molecule are suitable for the present use and ZoB. from ITS patents 2 180 805, 2 245 971, 2,283,326, 3,097,908, 3,088,790 and 3,100,673, British patents 490,945, 510,453 and 953,428 and Belgian patents Patents 608,829 and 652,691 are known. You let yourself Manufactured in a variety of ways, such as by implementation of sulfur dyes and alkali metal sulfites or by coupling of diazotized aromatic amines, the thio- Have sulfate groups, with coupling components or by condensation of reactive halogen derivatives of "dyes with aliphatic or aromatic amines, the thiosulfate groups The thiosulfate groups can be attached directly to a carbon atom an aromatic ring of the dye or via bridges of aliphatic or hydrocarbon radicals, which can be substituted if desired and can be interrupted by heteroatoms, be bound »Such dyes usually contain 1-4 · bonded thiosulfate groups and in the case of azo dyes the thiosulfate groups can either on the diazo component or on the azo coupling component be part of or both *

The disperse dye is dispersed in the aqueous medium with the aid of a dispersing agent and the water-soluble orgäni _s see Thiosulfatfarbstoff is hereby present in aqueous solution when the aqueous, -Färbungsmasse containing these compounds is applied to the textile materials.

The aqueous coloring mass can by mixing an aqueous Dispersion of the disperse dye, which already contains the suitable dispersant, with the water-soluble one organic thiosulphate dye, which is in the form of a paste, of a powder or an aqueous solution before mixing can be produced.

The aqueous dispersion of the disperse dye can be prepared in a customary manner, for example by diluting a Disperse dye powder with a "particle size of 10-40" Micron or an aqueous disperse dye paste of a Particle size from 0.1 - 1 micron, which is already the dispersant included, with water.

Disparate dyes are a well-known class of dyes, many of them as C.I. disperse dyes in the COLOR IHDEX listed are · A group of disperse dyes, without limitation, which are particularly useful in the present Processes are those of the benzothiazole, anthraquinone, Pyrazolone, methine, quinizarine, azo, nitrodiphenyiamine,

00 98 38/1985

Nitroacridone, quinoline, faphthaquinone and naphth (2,3-b) indolizine type.

The term "azo dyes" as used herein denotes dyes with at least one -N = Ii group per molecule and this also include dyes with more than one -N = H group per molecule . . ·.

The amount of each dye employed in the aqueous dye composition is determined by the depth of that desired for each fiber Coloring determined, the disperse dye for the polyester fibers and · the water-soluble organic thiosulfate dye is intended for the cellulose fibers. General will be about 1 - 120 g, usually 15-3Og of the disperse dye and about 0.1-100 g and usually 5-50 g of the water-soluble Thiosulfate dye, calculated as solids, per liter of aqueous coloring matter used. It goes without saying that at least one disperse dye and at least one water-soluble Thiosulphate dye in the aqueous dye mass is used and that if desired more than one disperse dye and / or more than one water soluble thiosulfate dye can be used in the coloring matter.

The aqueous dye mass is then applied to the mixed fibers. The application can be in any desired manner, for example by dipping, spraying or

00 9838/198 5

DIE aqueous coloring composition ka3m from room temperature up to about 85 ⁰ C to be accommodated, and is preferably between about 35 and 60 ⁰ C (TQO - HO ⁰ F) applied "

After applying the aqueous dye mass, the Fibers practically dried to dryness, for example by means of hot air in a heated, sealed frame, by infrared heat or contact heat. Desired case & · can the fibers are braided or steamed before drying to prevent the thiosulphate dye from penetrating to promote the cellulose fibers,

After drying, the fibers are heated sufficiently to fix the disperse dye on the polyester fibers' »This heating is carried out in the usual way for heat setting disperse dyes on polyester fibers and the water-soluble organic thiosulfate dye has no influence on the conventional heating or disperse dyes nor will the water-soluble thiosulphate dye influenced by the heating. Usual heating devices for thermosetting the disperse dye are hot-air roller curing ovens (thermosol ovens), infrared ovens and contact heat, for example from hot rotating cylinders ₀ Zei.t and temperature for

003838/1985

The heating of polyester fibers to fix disperse dyes is mainly determined by the heating equipment used and the weight of the textile material and to a certain extent by the moisture content of the practically dry textile material at the beginning of the heating period.Generally, the temperature varies inversely with time are, fixing may be accomplished by virtually dry textile materials dry tensile air 175-235 ⁰ C (350-450 ⁰ F) for about 15 seconds "up to 3 minutes, usually 200 - 22Q ⁰ Q for 45 - 90 seconds and preferably 21O ⁰ C (410 ⁰ F) exposed for 90 seconds "If hot rotating cylinder are applied, the fixation may be achieved by the textile materials with the approximately 200-235 - heated (400 45O ⁰ F) cylinders for approximately 12 - Are brought into contact for 20 seconds, preferably 15 seconds at 210 ¹ U (410 ^{0 F), if infrared} ovens are used, the fixing can be achieved when the substantially dry textile materials infrared units of about 435 - are subjected to 10 seconds in a conventional manner - 1100 ⁰ C (1000-2000 ⁰ F) for about. 6

Subsequent to the fixation of the disperse dye on the polyester fibers, the fibers, which carry the non-fixed water-soluble organic dye in the thiosulfate salt form, are _{brought into contact with an aqueous Na 2} Sp ^ fixing solution in order to fix the water-soluble organic dye on the cellulose fibers.

■ - "& _ - ■■ - -.. - ■■■ ..- ■""

The fixing solution contains an aqueous solution of ITa ₂ S ₂ -i->. The term Na ₂ S ₂ ^ used here denotes - .a sodium "polysulphide or mixtures of sodium polysulphides, for example disodium sulphide or disodium trisulphide or disodium tetrasulphide or mixtures of two or three such polysulphides. In the case of mixtures, the designation 2-4 is not on the sulfur atom necessarily a whole number of sodium polysulphides are known and can be prepared by adding sulfur bloom to a hot aqueous solution of sodium sulphide.

The amount of Na ₂ S ₂ - ^ used relates to the amount of the water-soluble organic thiosulfate dye to be fixed; about 0.0? - 0.46 g of Na ₂ S ₂ ^ and preferably about 0.214 g of Na ₂ S ₂ λ can be applied to the fibers for every g of thiosulfate dye · on the fibers. If desired, the fixing solution can also contain a simple water-soluble / inorganic electrolyte, for example NaCl, in order to prevent those dyes which have a tendency to bleed into the fixing solution.

The Na ₂ S ₂ - ^ is applied as an aqueous solution to the fibers usually at room temperature and can be applied by a cushion pressing process, spraying, Ειηΐαμοΐιβη the fiber into the solution or any other suitable method,

00903 ^ 8/1985

A rapid convenient and exemplary process is that the fibers grope having thereon the unfixed water-soluble organic Thiosulfatfarbstoff by a Polst containing about 1-1Og Na ₂ S ₂ "- ^ per liter of fixing solution to each 1 wt _o - to $ of Thiosulfatfarbstoffes contains the fibers, whereupon the fibers are squeezed between rubber-coated press rollers, so that a 60% moisture absorption of the fixing solution, based on the fiber weight, sets in. The thiosulfate dye is fixed very quickly and can be used for practical purposes as Fixation can usually be considered complete when the dye and NapSp-4 have been in contact for about 1-30 seconds.

There is no particular advantage if the Na ₂ S ₂ ^ ..- solution is kept above room temperature.

After contact with the Na ₂ S ₂ ^. the fibers are washed with water, which can be at room temperature. The water is used to remove polysulphide salt residues and other water-soluble residues from the fibers. If desired, the fibers can be passed through air, steam, or saline before washing. -

After washing, the fibers can be rinsed and used Way to be dried.
