SU852984A1 - Ink for printing on cotton fabrics - Google Patents

Description

The invention relates to the field of dyeing and finishing production, namely, to paint for printing cotton material.

Known ink for printing cotton material containing 10-30 g / kg of active dye, 80-120 g / kg of urea, 10 g / kg of ludigol, 7-10 g / kg of soda ash, 70-79.3 g / kg of modified starch thickener - starch-metasilicate, and the rest - up to 1 kg of water [1].

The disadvantage of this paint is the insufficient degree of fixation of the dye on the material (43%).

The purpose of the invention is to increase the degree of fixation of the dye on the material.

This goal is achieved due to the fact that the known paint as a modified starch thickener contains a grafted copolymer of starch with polyacrylic or polymethacrylic acid in a ratio of 0.72: -.1 - 1.25: 1 (PSK-1), respectively, in the following ratio components, g / kg:

Active dye 10-30

Urea 80-120

Ludigol5-10

Soda ash (25th aqueous solution) 5–125

Modified starch thickener 52-157

Water The rest (up to 1 kg)

Example 1. Cotton fabric 5 is printed with printing ink having the following composition, g / kg:

Active red dye

purple 2 CT 10 Urea 80 Thickener based on PSK-1 520 Ludigol 5 Soda ash (25% solution) 5 Water 380 The fabric is dried after printing, s

soar for 10 min and first washed with cold and then warm (50 ° C) water. In conclusion, the tissue is washed with hot (80–90 ° С) water, hot (80–90 ° С) surfactant solution (2 g / l) and again with hot and cold water.
