SU852985A1 - Method of washing acetyl-cellulose textiles printed with dispersed dyes - Google Patents

Description

0.2 g / l of triethanolamine at a solution temperature of 15 ° C, incubated for

3 minutes and washed in the pass-through apparatus according to the following mode: the first box is cold running water, the second box is an aqueous solution of sodium hydrosulfite 1.0 g / l and soda ash 0.5 g / l, temperature 55 ° C, the third box is an aqueous solution acetic acid 0.5 g / l, temperature 35 ° C. This is followed by drying of the fabric and appropriate finishing.

Example 2. Diacetate tissue art. 32567 type printing ink of the following composition, g / kg ink:

Disperse dye

brown25

Urea75

5% water thickener

Salvitozy MVS300

2% water alginate zagastkaTo 1 kg

After printing and maturation in superheated steam at 150 ° C for

4 min, the fabric is fed to the wash. Before washing the fabric is moistened to 70% moisture with an aqueous solution containing

0.4 g / l precellar W-OF (technical product of the oxyethylenation of technical fatty alcohols), 1.2 g / l soda ash, 0.25 g / l triethanolamine at 17 ° C, incubated for 10 min and washed in a flow apparatus the next first box is cold running water, the second box is an aqueous solution of sodium hydrosulfite 1.0 g / l and kalp. irovina soda 0.5 g / l, temperature

55 ° C, the third box - an aqueous solution of acetic acid 0.5 g / l, temperature 35 ° C. Next comes the drying of the fabric and the appropriate finishing.

Example 3. Triacetate art. 42416 type printing ink of the following composition, g / kg of ink:

Dye disperse orange 4K30

Urea150

5% water thickener

Salvitozy MVS540

2.5% pa of Indalka PA-3 thickener (ether of carob seed flour) Up to 1 (kg)

After printing and maturation in superheated steam at 155 ° C for 5 minutes, the fabric is fed to the washing. Before washing, the fabric is moistened to 80% moisture with an aqueous solution containing 0.5 g / l of DS-7 synanol (a product of technical fatty alcohols oxethylation), 1.5 hl of soda ash, 0.3 g1l of triethanolamine at 20 ° C, withstand moist fabric for 20 minutes and washed in a throughput apparatus according to the following mode: the first box is cold running water, the second box is an aqueous solution of sodium hydrosulfite 1.0 g / l and soda ash 0.5 g: l, temperature 55 ° C, third box - an aqueous solution of acetic acid 0.5 g / l, temperature 35 ° C. Next followed by drying the fabric and appropriate finishing. The results of washing the material are shown in the table.

Note: For washing according to a known method, the triacetate fabric art. 42416, printed and matched according to the visitor 3.

As can be seen from the lazy tissue in Table 40 before washing. Odnadannyh, using the proposed method allows you to more quickly and qualitatively wash the printed fabric. The effectiveness of the washing increases with increasing curing time. It is not advisable to withstand a moistened cloth for more than 20 minutes because the washing efficiency does not increase significantly.
