Abstract

The invention relates to textile and finishing production, in particular to a backup printing method intended for dyeing with cubic logs. The aim of the invention is to obtain a color reserve on the basis of a cubic dye for dyeing cubic photos, providing a clear contour and preventing the fixation of cubes in the backup area. The goal is achieved by the fact that upon receipt of a reserve by applying a printing ink containing a reserving agent, drying, steaming, dyeing the background with subsequent known final operations (oxidation, washing, soaping, washing) as a reserving agent contains thiourea dioxide, and the background is dyed immediately after drying. 1 tab.

Description

The invention relates to textile and finishing production, in particular to a backup printing method intended for dyeing the background with cubic logs.

The aim of the invention is to obtain a color reserve on the basis of a cubic dye for dyeing the background with cubogens, providing a clear contour and preventing the cubogen from fixing in the backup area.

Example 1. Cotton fabric is printed with a composition containing 7g / kg: Vat gold yellow KHP100 Glycerin 50 Potash 65 Thiourea dioxide 85 Thickener Others are dried at 70 ° C, impregnated with dye solution containing / l: Cubogen blue 4K 100 NB1 wetter Urea 150 Potash 60

and steamed at 101-102 ° C for 3 minutes, then the sample is oxidized in running cold water or acetic peroxide solution at 50 ° C, washed with warm water, soaped on a bale for 10 minutes, washed with warm and cold water and dried . A reserve of golden yellow color is obtained on a blue background, the reserve contour is clear. The reflectance spectra of the reserve and the coloration obtained by direct printing with the same composition are close.

and then treated as in Example 1. A reserve of yellow is obtained on a purple background. The outline of the reserve is clear. The reflectance spectra of the reserve and the coloration obtained by direct printing with the same composition are close.

and then processed analogously to example 1. Get on the scarlet background reserve blue. The outline of the reserve is clear. The reflectance spectra of the reserve and the coloration obtained by direct printing with the same composition are close.

Example 4.

and then it is treated as in Example 1. A white reserve — a cubic dye, which is part of the reserve, is not fixed on the fabric in the zone of deposition of the printed composition.

and then treated as in example 4. Get on a red background poor quality reserve, shaded background color. The outline of the reserve is blurred. 40 The indicators of color resistance to physicochemical effects according to examples 1-7 are given in the table.

Due to the presence in the printing ink as a reserving substance of thiourea dioxide, 45, a method of obtaining a color reserve based on the cubic dye for dyeing the background with cubogens was created. High-quality color redundancy is ensured (the contour of the backup pattern is clear and prevents the background dye from fixing when the background is dyed with cubic gens). Taking into account the coloristic features of the cubogens (they supplement the assortment of vat dyes with the lack of light-resistant scarlet and red marks), the proposed method expands and enriches the techniques of artistic and color design of textile materials.

Claims (1)

Claims The method of backup printing by applying to the fabric a printing ink containing a reserving agent, drying, steaming, dyeing the background with subsequent known final operations, characterized in that in order to obtain a color reserve based on the cubic dye for dyeing the background of cubic limes, providing a clear contour and preventing fixation of cubogen in the backup area, the printing ink as a reserving substance contains thiourea dioxide, and background dyeing dt immediately after drying.  The color quality of the reaera was assessed by comparing the spectrum of the reflection of the color of the reserve during the subsequent dyeing of the background with the cubohemum and the coloration obtained by the same composition by direct printing without the subsequent dyeing of the background.
