SU994598A1 - Composition for dyeing textile fiber - Google Patents

Description

The invention relates to dyeing and finishing production, in particular, to a composition for dyeing textile fibers.

Known composition for dyeing textile fibers, containing 10 g of sodium salt L, L-diphenyldiimide 1, 1-dinaphthyl, 4,4, 5,5, 8, 8-hexacarboxylic acid, 80 g glycerin, 100 g of an alkaline agent - potassium carbonate, triethanolamine or soda ash, 100 g of reducing agent - rongalite or sodium dihydrogen sulfite, 100 ml. water, and the rest, thickener 1.

The disadvantage of this composition is that it can be used to dye only cellulosic fiber. In addition, the coloring on the fiber is fragile to friction, alkaline and wet processing (3-4 points).

The purpose of the invention is to expand the range of fibers used, as well as increasing the intensity of color and its strength to friction, alkaline and wet processing.

The goal is achieved due to the fact that the composition is known. Qi additionally contains turpentine at a ratio of reducing agent to

alkaline agent, respectively (1-2,5) :( 1-1) and the content of components, (g / kg):

Sodium salt of N, N-diphenyldiimide - 1,1-dinaphthyl - 4.4, 5.5, 8.8-hexacarboxylic acid 15-20

Glycerin 30-80

Specified alkaline agent 50-60

Water 79-80

ten

The specified reducing agent 20-60

Turpentine 0,1-10

Thickener Rest up to 1 kg.

Example 1. 15 g of sodium salt of N, N - diphenyldiimide - 1, 1 - 5 dinaphthyl - 4.4, 5.5, 8.8 - hexacarboxylic acid is dissolved in 79 ml of water, injected, g: glycerol 80; potassium carbonate 60; rongalite 60; turpentine 0,1; The weight of the printed area is adjusted.

20 ki starch tragantine or a mixture of starch and carboxymethylcellulose thickener up to 1000 g. Cotton, staple, and viscose are printed with prepared ink.

Claims (1)

25 or flax cloth, dried at 50-60 ° C, then passed through a restorative brew at 101-103 C for 3-12 minutes, oxidized in a solution containing 3 ml of a 30% peroxide of hydrogen and 5 ml 30% acetic acid in 1 liter, then washed with warm water, soaped and washed with hot and cold water. Red color stains with a blue tint resistant to wet treatments and light are obtained. Example 2.17 g of sodium salt N, N of diphenyldiimide - 1, l - dinaphthyl - 4.4, 5.5, 8.8 - hexacarboxylic acid is dissolved in 80 ml of water , enter, g; glycerin 80 potassium carbonate 50; hydrosulfite 20; turpentine 0,1; the weight of the printing ink is adjusted to 1000 g with starch-tractive agglomerate. Cotton fabric is printed with the prepared ink, dried at ZO-S, and then treated with hot air for two minutes. Next come, ka described in example 1. Get a pink color, durable to wet treatments and light. Example 3. 20g of sodium salt-H, L-diphenyl diimide l, l-dinaphthyl — 4.4, 5.5, 8.8-hexacarboic acid is dissolved in 80 water, 30 g of glycerin, and g are added; starch-tragic behind Drug 660670; dextrin thickener; calcinated soda 60; triethanolamine 0.1; 40% rongalite 120; turpentine 0.1. After mixing the components, the paint is heated to 35 ° C, 5.0 hydrosulfite is added and the dye is recovered within 10 minutes. The fabric is printed, dried, passed through a replacement cereal, and then oxidized. On acetate silk get about red color. Example 4. 15 g of N, N-diphenyl diimide sodium salt - 1,1-- dinaphthyl - 4,4, 5,5, 8,8-hexacon of boic acid are dissolved in 80 ml of water, 30 g of glycerin are introduced, 80 ml of water and 30 g of triethanol are added, 343-333 g of tragic starch thickener, 100 g of dextrin condensate, 18.7 g of 15% soda ash in starch-tragative for thickening, 120 g of 40% a solution of ronaglit, 10 g of turpentine in 1 kg of printing ink. Further operations (printing fabrics, drying, etc.) according to example 1. A red color is obtained on fabrics made of natural silk, wool, polyamide. The use of the proposed composition allows to obtain a red color on cellulose, protein ,. polyamide and acetate fabrics with good resistance to physical and chemical5 effects such as resistance; to sweat 4/5, to water 5/5, To soap, soda at 40 ° C 5/5, to soda at 100 ° C 4-5 / 5, to a wipeable 4-5 / 4, to dry friction 4-5. DETAILED DESCRIPTION OF THE INVENTION Composition for textile fiber dyeing, containing sodium aol N, N-diphenyldiimide-1,1-dinaphthyl - 4.4, 5.5, 8.8-hexacarboxylic acid, glycerin, alkaline agent - potassium carbonate, triethanolamine or soda ash, reducing agent - Rengalite or sodium hydrosulfite, thickener into water, which is different from the fact that, in order to expand the range of fibers used, as well as to increase the color intensity and its strength to friction, alkaline and wet processing, it additionally contains turpentine with a ratio reducing agent and alkaline agent, respectively (1-2.5) :( 1-1J and content of components, g / kg: sodium salt N, N - Diphenyldiimide 1, dinaphthyl - 4.4, 5.5, 8.8 h-xacarboxylic acid 15-20 Glycerin 30-80 Specified alkaline agent 50-60 Water 79-80 Specified reducing agent 20-60 Turpentine 0.1-10 Thickener The rest is up to 1 kg.
