SU1636494A1 - Method of washing woven fabric of cellulose acetate rayon printed with dispersed dye - Google Patents

Abstract

The invention relates to dyeing and finishing production, in particular, to a method of washing printed textile material from acetylcellulose fibers printed with disperse dyes. The invention allows to increase the degree of whiteness of an unpainted background from 71.4 to 74.1% of the strength to wet treatments, sweat and friction from 3-4 to 4 and 5 points due to the fact that the material is treated first with water and then with an aqueous solution based on quaternary ammonium salt of polyglycol ethers of alkylphenols conc. 0.3-0.5 g / l, sodium hydrosulfite, non-ionic surfactant and soda ash at 55-60 ° C and then with an aqueous solution of sodium chloride conc. 50-150 g / l and washing with water. 2 tab.

Description

The invention relates to the field of dyeing and finishing production, in particular, to a method of washing a textile material made from dispersed dyes of acetylcellulose fibers.

The purpose of the invention is to increase the degree of whiteness of an uncolored background and the strength of color to a solution of soap, sweat and friction.

Example 1. Triacetate fabric (art.42793) is printed in red, which has the following composition, g / kg of dye: Scarlet dispersed polyester dye20

Urea 100

2.3% water alginate thickener (Manutex PC) Up to 1000

After printing and maturing in a superheated steam environment at 155 ° C for 6 minutes, the fabric is fed for washing. Washing is carried out at the checkpoint apparatus according to the following mode: the first box is cold flowing water; the second box is an aqueous solution of syntanol DS-10 1.0 g / l (the product of hydroxyethylation of synthetic fatty alcohols), soda ash — 2.0 g / l, sodium hydrosulfite 1.0 g / l, quaternary ammonium salt of polyglycol alkylphenol ethers 0.3 g / l, solution temperature 55 ° C; third box - an aqueous solution of sodium chloride 50 g / l, solution temperature 80 ° C; fourth bath - cold running water (15 ° С).

followed by drying the fabric and appropriate finishing.

Example 2. Diacetate tissue (art. 232567) is printed with printing ink of the following composition, g / kg of ink:

Disperse orange 2K polyester dye25 Urea 75% water thickener salvitose MBC 300 2% water alginate thicken Up to -1000 After printing and maturing in superheated steam at 160 ° C for 5 minutes, the fabric is passed to the wash. The flushing is carried out in the pass-through apparatus in the following mode: the first box is cold water; the second box - an aqueous solution of precellar-OG (the product of the oxyethylation of technical fatty alcohols) 1.5 g / l, soda ash 2.5 g / l, sodium hydrosulfite 1.5 g / l, quaternary ammonium salt of alkyl glyphenol ethers 0, 4 g / l, solution temperature 55 ° С; the third box is an aqueous solution of sodium chloride concentration of 100 g / l, temperature 95 ° С; the fourth box is water, the temperature is 17 ° С. This is followed by the drying of the fabric and the appropriate finishing.

2.5% aqueous thicken of the PA-3 Indalka (ether of carob seed flour) Prior to LLP After printing and maturing in superheated steam at 160 ° C for 5 minutes, the fabric is fed to the wash. Washing is carried out at the checkpoint apparatus according to the following mode: the first box is cold flowing water; the second box - aqueous solution of precellose-OG 2.0 g / l, soda ash 3.0 g / l, sodium hydrosulfite 2 g / l, quaternary ammonium salt of polyglycol ethers of alkylphenols 0.5 g / l, solution temperature 60 ° C; the third box is an aqueous solution of sodium chloride concentration of 150 g / l,

temperature 105 ° C; the fourth box is water that is gchenna, temperature is 20 ° С. This is followed by drying and appropriate final finishing. The results of the washing material are given in table.1. For washing according to a known method, the fabric printed and steamed according to example 2 is used.

As can be seen from the above data, the application of the proposed washing method increases the degree of whiteness of the uncolored background and the color strength to the solution of soap, perspiration and friction.

When using the concentration of the backup component lower than that specified in example 1 (0.3 g / l), the whiteness of the uncolored background decreases, and with increasing concentration of the backup component above O, 5 g / l (more than that used in example 3) further increase the brightness Uncolored background practically does not occur.

The results of carrying out the proposed method without introducing an additional reserving component and processing the material with a hot solution of sodium chloride followed by treatment with cold water are shown in Table 2.
