SU1151559A1 - Blend dye for colouring cellulose fibres black - Google Patents

Description

The invention relates to the paint industry, in particular to the mixed dye for cracking cellulose fibers in black. The aim of the invention is to simplify the technology of obtaining a mixed dye and reduce its consumption while maintaining the color intensity and its resistance to chemical physic effects. Example 1. 71.3 g of the chromium complex (1: 2) 8- (2-amino-4 -chloro-symmetr. triazin-b -yl) amino-2- (5-11Itro-2 -oxypheno azo) 1-naphthol-3,6-disulfonic acid of the formula (mixed with 8.5 g of the known copper complex 8- (2 -aminO4-chloro-symmetr. triazIn-b-and -amino-2- (5 -sulfo-2 -oxyphenylazo) -1 -naphthol-3, 6-disulfonic acids of formula 11. To stabilize the dye, diethyl is added before or after mixing. sodium methanylate in the amount of 2.55 g. To remove dust, a transformer oil is introduced before ish after blending: oil in an amount of 2.65 g. A composition of the composition is obtained, wt%: Chromium complex of formula 184 Copper complex of formula 1110 Sodium diethylmethyl acetate 3 Transformer oil 3 The resulting composition dyes cel line fibers black with a reddish tint. Stains resistant to wet treatments and light Example 2. The composition is prepared similarly to the previous example, added to the 76.4 tonnes of the chromium complex of the formula 1 15.1 g of the copper complex form A silicone oil, 0.9 g, and a stabilizer — a mixture of di-and mono-phosphates of potassium and sodium — 2.6 g are introduced as a dust collector. A composition of the composition, wt.% is obtained: Chromium complex of the formula 190 Copper complex of the formula 116 Phosphate mixture 3 Silicone oil1 The resulting composition dyes cellulose fibers in a deep neutral black color. Stains are resistant to wet treatments and light. Example 3. The composition was prepared analogously to example 1, added to 77.3 g of a chromium complex of the formula, 117.3 g of a copper complex of the formula, 5 g of urea as a stabilizer and 0.9 g of dode benzene dust collector. Composition, wt.%: Chromium complex of the formula I Copper complex of the formula II Urea Dodecylbenzene Semi-yellow composition colors cellulose fibers in black with reddish OTfeHKOM. Stains are resistant to wet treatments and light. Example 4. The composition was prepared as in example 1, added to 72.9 g. chromium complex of formula 1 3.6 g of copper complex of formula 11, 13.5 g of stabilizer and 0.9 tons of dust collector. Dust and stabilization of the dye is carried out similarly to examples 1-3. Composition, wt.%: Chromium complex of the formula 180 Copper complex of the formula 114 Stabilizer, 15 Contour1 The resulting composition dyes cellulose fibers black with a green shade. Stains are resistant to wet treatments and light. Example 5. 76.4 of the chromium complex (1: 2) of formula 1 is mixed with 5.1 copper complex of formula 1: 8- | 2- {2 -sulFO-5- (4-chloro-2 - (3-sulfophenylamino) -triazinyl-b - amino-fsnylamino-4-chlorosym. Triazin-6 -yl-amino-2- (5-sulfo-2 - Oxyphenylazo) -1-naphthol-3,6-disulfonic acids Dust-freezing and stabilization - Dye prowler t analogous to Examples 1-4. Composition, wt.%: Chromium complex of formula 190 Copper complex of formula 1116 Stabilizer3 Dust remover1 in deep neutral black 1 Shet. Stains are resistant to wet-handling and light. EXAMPLE 6 Cotton fabric is printed with paint containing Our dye composition according to Example 2 or Example 5, urea 50 g / kg, water 200 g / kg, alginate thickener 620 g / kg, ludigol 10 g / kg, soda ash 40 g / kg. Printed fabric is dried and steamed in a medium saturated pair at 10О - 102С

7 min and washed. A printed print of deep black is obtained.

Example 7. Cotton fabric plus solution containing the dye composition according to example -1 or according to example 5, urea-50 g / l, wetting agent NB 22 g / l and soda ash 40 g / l. Oplusovaya fabric is dried, steamed in an environment of saturated steam at 100-12CfC for 7 minutes and washed. Get the color of deep black.

The dye compositions of examples 1, 3 and 4 are used in dyeing and printing cotton15594

paper fabrics as in Examples 6 and 7, obtaining similar results.

Compared with the known dye black and cobalt containing 5 active black K (commercially available commercially), the invention makes it possible to obtain compositions of light resistant active dyes for coloring cellulosic fibers into deep black color with high strengths to physicochemical effects and exclude the use of scarce raw materials, cobalt and its salts, replacing them with more affordable copper salts (copper sulfate).
