DE1176605B - Process for dyeing and / or printing textiles made of cellulose - Google Patents

Description

Process for the dyeing and printing of textile material or of cellulose or additive to Patent: 1,154,789 object of the patent 1,154,789 is a process for dyeing and printing of textile material or, or of cellulose, wherein the Tetrazaporphinfarbstoffe the general formula T- ( CH2-X) n where T is the residue of a copper or nickel tetrazaporphine, X is a quaternary ammonium salt group, which in turn bears at least one free or functionally modified sulfonic acid group or carboxylic acid group, and n is an integer from 1 to 8, in the absence of weakly acidic agents applies to the material by customary dyeing and / or printing processes and the material treated in this way is heated to temperatures between 50 and 150 ° C. in the presence of alkaline agents.

It has now been found that textile goods such as fibers, threads, flakes, Woven and knitted fabrics made from native and / or regenerated cellulose according to the process of the main patent in a simple manner that is rub-proof and wet-fast dyeing and / or printing can, if the previously identified tetrazaporphin dyes together with Reactive dyes for dyeing and / or printing textiles made of cellulose used.

Reactive dyes are in the literature, for example in the publication "To the knowledge of reactive dyes" by J. Wegmann in the magazine Textilpraxis, 13 (1958), on pages 936 to 940 and on pages 1056 to 1061, in the publication "Reactive Dyes for Cellulose Fiber Goods "by BCM Dorset in the journal Textile Manufacturer (1958), on pp. 522 to 526, and in the publication" Chemismus der Reaktivfarbstoffe "by H. Z o 11 inger in the journal Angewandte Chemie, 73 (1961 ), on pages 125 to 136.

Otherwise, the information and measures of the main patent apply.

The parts and percentages given in the examples are weight units. Example Cotton fabric is printed with a printing paste containing 1000 parts of 30 parts of the yellow reactive dye of the formula given in Example 2 of German Auslegeschrift 1 112 225 and under No. 3 in the table of Example 1 of French Patent 1 182 529 40 parts of the turquoise-blue dye described in Example 1 of German Patent 843 725 in the form of an approximately 50% aqueous slurry, 50 parts of sodium carbonate, 500 parts of 10% alginate thickening and 380 parts of water. The printed material is then dried at 60 to 70 ° C. and steamed for 5 minutes at 100 to 103 ° C. After the usual soaping and drying, bright green prints with very good fastness properties are obtained.

Example 2 Cotton fabric is printed with a printing paste containing, in 1000 parts, 60 parts of the turquoise-blue dye used in Example 1, 10 parts of the blue reactive dye of the formula identified in Example 4 on page 15, line 6 of Belgian patent 560 034 Contains 20 parts of sodium carbonate, 10 parts of 38 'B6 aqueous sodium hydroxide solution, 500 parts of 10% alginate thickener and 400 parts of water. The printed material is then dried and steamed for 5 minutes at 100 to 103 ° C. The printed fabric is then rinsed, soaped and dried. Wet-fast prints in bright blue-tinged turquoise shades are obtained. Example 3 20 parts of the yellow reactive dye used in Example 1, 40 parts of the dye suspension described in the second paragraph of this example, 50 parts of urea and 50 parts of sodium carbonate are dissolved together in 1000 parts of water. Cotton fabric is impregnated with this solution using a padder (the liquor pick-up should be 800%). The fabric is then dried with the aid of a so-called hot flue at 80 ° C and then steamed for 5 minutes at 100 to 1030C. After the usual rinsing and soaking of the material to be dyed, a bright green dyeing with very good wet fastness properties is obtained.

The dye slurry used in the first paragraph of this example is produced as follows: 50 parts of an aqueous filter material that contains 10 parts contains a mixture of tris- and tetrakischloromethyl copper phthalocyanine, 10 Parts of sodium dimethylglycocolland 5 parts of water add up to about 2 to Stirred for 3 hours at 90 to 95'C until a sample of the reaction material in Water is clearly soluble. The low-viscosity dyestuff suspension obtained in this way is used for dyeing in the manner indicated in the first paragraph of this example.
