The invention relates to finishing jjOMy textile production, in particular, to the composition of printing ink for cotton-cotton fabric.

The purpose of the invention is to reduce the consumption of thickeners and the elimination of the toxic carrier while maintaining the strength properties of Color and the degree of dye fixation on the fabric. ; As a thickener, a mixture of low viscosity alginates with starch ether in a mass ratio of; 2: 1 is used.

As an organic solvent that reduces cotton fibers in the swollen state under conditions of drying and heat-setting, as well as the case with its solvent dispersed edge: the Sitel at the fixation temperature and: the medium for its diffusion deep into the cotton fiber is used polyethylene l picol and / or polypropyl-1g glycol, and / or their EFF1P with mol, m. 300-600 in combs 80-125 g / kg. When the content in the printing ink of an organic solvent mite and above the specified interval, a decrease in the degree of fi: saturation, respectively, on cotton and by: 1 ether fibers of blended fabric, is observed

Sodium tetraborate is used as a substance that causes the formation of one of the components of the mixed thickener, namely starch ether. The use of a mixed thickener consisting of low viscosity alginate and starch ether with the addition of tetrabrate. Sodium increases the dye yield from the thickener polymer film and the dye fixation on the cotton fabric. When the content of sodium tetraborate in the printing ink is less and more than the specified interval, a decrease in the fixation of the dispersed dye is observed.

The amount of dye in a printing ink depends on the form produced (powder or paste) and on the required color intensity. In the case of the use of dyes in the form of a 30% paste, its amount is increased by 3 times.

Disperse dyes used in the proposed composition have the general formula

Disperse dyes have a mol.m., 300-400 and a slight solubility in water and an organic solvent at 20-25 C.

Printing is carried out on printing equipment, followed by drying at 90 and heat setting with hot air at 205-210 C for 90-60 s.

PRI me R s 1-5. To prepare the composition, a thickener of low-viscous sodium alginate (Lamitex-10) in an amount of 90 g in powder form is gradually introduced into 910 g of cold water with constant stirring and formed to swell for 1 hour. A thickener of starch ether (Solvitose C5 ) prepared in the same way. Then the thickeners are mixed in a 2: 1 ratio by weight (2 parts of alginate thickener and 1 part of thickener from starch ether). .

To the prepared mixed thickener in the amount of 400-500 g, 5-10 g of ludigol dissolved in warm water and 3-5 g of sodium hexametaphosphate are added. After stirring, 80-125 g of an organic solvent is added, the composition is stirred, and 0.5-1.5 g of sodium tetraborate dissolved in warm water is added to it. With stirring, 20-60 g of dispersed dye is added to the specified total

formulas and water up to 1000

For printing use fabric art. 82188, containing 67% polyester and 33% cotton.

The resulting printing ink is applied on cotton-cotton fabric, dried at 90-100 ° C and heat-set at 205-21 ° C and time 60-90 seconds. The data are given in table.1.

As can be seen from the data presented in Table 1, the degree of fixation of disperse dyes from cotton-cotton fabric is increased at a concentration of sodium tetraborate of 0.5-1.5 g / kg of printing ink. Below and above this interval, the degree of fixation decreases.

Example of fish-10. A composition containing sodium tetraborate 1.5 g / kg of printing ink is used. Use disperse dye of the formula

ABOUT

The amount of polyethylene glycol varies in the range of 0-125 g / kg.

The resulting printing ink is applied to the cotton-cotton fabric, dried at 90 ° C and heat-set at 210 ° C for a time of 60 seconds.

Data are given in gabl, 2.

For examples 6-10, the degree of dye fixation is greatest in the range of concentrations of polyethylene glycol 80-125 g / kg of printing ink, below and above this range the degree of fixation of dyes on cotton fabric is reduced.

Examples 11-13. A formulation containing sodium tetraborate 1.5 g / kg and polyethylene glycol with 90 g / kg of printing ink is used.

The data are given in table 3. Examples 15-18. The ratio of components and the degree of fixation are given in table 4.

JO As can be seen from the data of Table 4, the degree of fixation of the dyes does not actually depend on the concentration of sodium hexametaphosphate within these limits at a constant water hardness. The amount of J5 honestly thickeners within the specified limits also does not affect the degree of fixation of the dyes.

Examples 19-23. The ratio of components and the results are shown in Table 5.

The degree of fixation of the painters in the indicated concentration intervals of the dye and ludigol is almost unchanged. At the same time, the proposed composition 25 of printing ink for cotton-cotton fabric is more economical than the known one (Example 14), since it allows reducing the consumption of thickeners and eliminating the use of carriers that pollute wastewater.

The resistance of color to physical and mechanical effects corresponds to PC (strong dyeing).
