DE2013891C - Process for the simultaneous coloring or printing of textile fiber mixtures with cationic and anionic dye - Google Patents

Description

The present invention relates to a method for the simultaneous dyeing or printing of textile fiber mixtures, especially in the form of carpets or upholstery fabrics where at least one Fiber type has an affinity for cationic dye and at least one other fiber type has an affinity for anionic dyes Has dye, as well as those dyed or printed by the process according to the invention Textile fiber mixtures.

The single bath dyeing or printing of textile material made from fiber mixtures of different dye affinity depends on the selection of certain dyes for each type of fiber. The selection to be made often means a compromise with regard to the evenness and the authenticity of the results Coloration, liquor stability and other properties, because the ideal dye for one type of fiber is often completely unsuitable for the other. Typical For example, there are fiber mixtures which have to be overcome with such difficulties when they are colored au .. 1 olyacrylonitrile and synthetic polyamide fibers or from polyacrylonitrile and cotton fibers.

Fs has now been found that fiber mixtures of the above mentioned type color very uniformly with satisfactory Echthcitscigenschaften and without a gray haze (so-called sandwich effect) on (<o color or in multiple colors, or may be printed by the fiber mixture at temperatures below the Aufziehtemperatur of the dyes impregnated or printed with an optionally thickened solution, which contains at least one cationic and at least one anionic dye, sufficient acid and buffer to maintain a pH of the solution between 3 and 7. at least 0.5 g of 1 sulfated or sulfonic compound as anion-active Auxiliaries and at least 0.5 g of an amide of aliphatic S bi: monocarboxylic acids containing carbon atoms or mixtures of such fatty acids with primary or secondary amines containing at least one lower hydroxyalkyl group and a water-soluble condensation product of equivalent F contains fatty acids with 8 to 20 carbon atoms or mixtures of such fatty acids with up to 3 equivalents of a di- and: or trialkanolamine and optionally other auxiliaries customary in dyeing, and completes the dyeing or printing by a moist heat treatment.

Instead of the above-mentioned amides, in the process according to the invention, according to the definition, Condensation products from 1 equivalent of fatty acids

45 mn 8 to 20 carbon atoms or mixtures of such fatty acids with 1 to 3 equivalents of a di- and / or trialkanolamine can be used. These condensation products can be prepared by the process described in US Pat. No. 2,089,212 by heating the fatty acids with 1 to 3 equivalents of di- and / or trialkanolamines. especially diethanolarnine. with the elimination of more than 1 mol of water. Condensation products of 1 equivalent of the fatty acids mentioned or of mixtures of such fatty acids are preferred, above all the acid mixture with 2 equivalents of dialkanolamine combined under the collective term "coconut oil fatty acids".

The amounts of anionic auxiliaries and amides to be used in the process according to the invention or condensation products can vary within wide limits and depend on both on the type and amount of dyes used as well as on the choice and composition of the Substrate. They can be used in quantities of up to 50 g liters of dye liquor or printing paste will. The anion-active auxiliaries are preferably used in amounts of 1 to 10 g liters of dye liquor or Printing paste urd the amides or condensation products mainly in quantities of 0.5 to 2.5 g liters used. The anion-active auxiliaries and the amides or condensation products are expediently used in a mutual weight ratio of about 1: 1 to 10: 1, preferably 1: 1 up to 5: 1.

Cationic dyes which can be used according to the invention are advantageously those that are technically easy accessible salts and metal halides, for example zinc chloride double salts of the known basic Dyes into consideration. These are, for example, thiazines containing onium groups. Oxazine. Diphenyl methanes, triphenyl methanes. Rhodamines. Azo and anthraquinone dyes, preferably monoazo, methine and azomethine dyes, ammonium groups are primarily to be mentioned as the onium group.

The anionic dyes which can be used in the process according to the invention are both so-called acidic wool dyes as well as reactive or substantive dyes of any classes into consideration, their The coloring agent is an anion. such as the alkali or ammonium salts of dye sulfonic or carboxylic acids or of 2: I metal complex dyes, namely metal-free or metallized sulfonicrtc mono-. Dis- or polyazo dyes, which also include the formazan dyes, their chromium, cobalt, nickel and Copper complexes and sulfonated anthraquinones, nitro and phthalocyanine dyes. As reactive dyes come those with the amino groups of wool fibers or with the hydroxyl groups of the cellulose fiber react and especially from the azo, anhraquinone or phthalocyanine dyes derive into consideration.

For the purpose of adjusting or raising the pH value of the dye liquor or printing paste between 3 and 7 are preferably used lower aliphatic carboxylic acids, especially monocarboxylic acids, such as formic acid or, above all, acetic acid and the usual buffer salts. like sodium acetate. Potassium acetate or ammonium acetate or the corresponding sulfates and phosphates.

The dye liquor advantageously contains b / w. Printing paste

acid-resistant thickener. The products known in textile printing are used as thickeners. z. B. locust bean gum derivatives, galactomannans. Tragacanth. Solvitose or British Gum. Cellulose derivatives, like methyl cellulose. Natural rubber and open rubber types, such as industrial rubber, or synthetic thickeners such as polymerization and copolymerization products of acrylic acid. Methacrylic acid or: maleic acid.

As a further aid, the dye liquor or 10 ' Printing paste, for example, fixing substances, such as ethylene carbonate; Solubilizers, such as Cellosolve: bactericidal and fungicidal compounds or contain moth repellants.

Dyeing ballots or printing pastes which can be used according to the invention are expediently prepared in such a way that that one dissolves the anionic dye in hot water, with the auxiliary mixture and optionally added to the thickener and the resulting solution after cooling to room temperature Stir in solution of the cationic dye. The latter is advantageously made with acid and buffer salt made into a paste and then dissolved in warm water and cooled.

As textile fiber mixtures dyed according to the invention or can be printed, z. B. those made of natural and synthetic polyamide fibers, natural and regenerated cellulose fibers and polyacrylonitrile fibers - among the latter too basic modified - into consideration. As a synthetic polyamide fiber material come with both anionic Dyestuff-dyeable fiber types as well as acid uiodified polyamide fibers used in the textile industry are known in question. Fiber mixtures of acidic and basic dyeable fibers are preferred synthetic polyamide, from polyacrylonitrile and synthetic polyamide or from polyacrylonitrile and Cellulose fibers, especially cotton.

The fiber blends can be in any form, e.g. B. as tufted material, non-woven articles, such as needle felt, woven fabric, knitted fabric, flake, twisted or braided yarn, etc. Preferably the textile fiber mixture to be dyed or printed according to the invention is used in Form of carpets, such as tufted carpets or furniture coverings and decorative fabrics, such as furniture plush and the like

The process according to the invention is suitable for dyeing by customary impregnation processes, for example by means of dipping, foulardicren, putsches or doctor blades, as well as for printing or for combinations of the methods mentioned.

The impregnated or printed fiber material is finished according to the usual type of fiber adapted methods, advantageously by steaming with neutral saturated steam at temperatures between 90 and 102 C followed by rinsing and drying.

Auxiliary fluid mixtures which can be used according to the invention of anion-active auxiliaries and the amides or condensation products mentioned have opposite known nonionic auxiliaries or auxiliaries have the advantage that with the first more stable dye liquors or printing pastes and / or more uniform, stronger colors. more brilliant, haze-free Dyeings or prints are obtained.
