SU89835A1 - The method of coloring cotton and other fabrics of plant origin - Google Patents

Description

Methods are known for introducing mordant dyes into nitdol solutions and the method for preparing c.Meiiia iHHx dyeing solutions and inks from diazo compounds and indigozols, as well as printing inks made up of nitrogenotol and sulfur dyes.

The proposed method of coloring cotton and cotton fabrics of vegetable origin allows printing with dyes, including one-time and one dye and mordant dyes together with a mordant.

The peculiarity of the described method is that the fabric impregnated with solutions of naphthols, azogols or other compositions: 1 are printed with inks containing a diazo compound together, a mordant dye and a solution of chromium salts or other metals, forming their varnishes with mordant dye mi A diazo compound in the form of N-diazosulfonate together with azo-component can be introduced into the printing ink, the dye is etched and the solution hromch n / fuph: rm: 1.to. printed

Kie produce tissue.

On the basis of the method described above, a neutralized solution of diazososedienes is contained in the treatment, a mordant dye is injected with the appropriate CTByiOHicfi solution, mostly with acetic chromium. The nanoparticulate azogram-filling fabric is dried, zaparnyu in zrennnke 5 min., Spilled with cold and hot, with water, we with a solution of powder (3 g / l at 70 °), washed with hot and cold water and dried.

The best way to get a wide variety of shades. The benzidine diazo compound in combination with the mordant yellow gives a rich brown color along the azotironed tissue. Variamine salt when combined with a mordant yellow gives green, olive and black colors with a greenish tint. A diazosulphonate obtained from variamine salt and sodium sulphate, when printed on non-azotable fabric in combination with a mordant yellow, gives black shading.

As protr, dye

A dry salt of viridone with chrompeak or with chromic acetate is applied.
