Abstract

The invention relates to the dyeing and finishing production of the textile industry and can be used to obtain patterns on mixed fabrics by burning off the cellulosic component. The invention allows reducing the loss of strength of the material, increasing its light resistance and facilitating the removal of carbonation products by treating it with an aqueous composition containing 15-25 wt.% Aluminum chloride, 1.5-2.0 wt.% Oxyalkylated monoalkylphenols based on propylene trimers, 3 to 5 wt.% Decanol and 6 to 8 wt.% Derivatives of galactomanan. 2 tab.

Description

The invention relates to dyeing and dividing the textile industry and can be used to obtain patterns on mixed fabrics by burning the cellulose component.

The purpose of the invention is to reduce the loss of strength of the material, increase its light resistance and facilitate the removal of carbonization products.

EXAMPLE 1 In 59.5% by weight of softened water, while stirring, 6% by weight of diagum A8 (a derivative of galacta-manon) are poured in. Stir until a homogeneous mass is formed and left until complete swelling (10-12 hours). ). Then, while stirring, 15% by weight of aluminum chloride dissolved in 15% by weight of water, 1.5% neonol AF9-12 (oxyalkylated monoalkylphenols based on propylene trimers TU 38 103625-87), 3% decanol (TU 609 -1574-75) and mix until homogeneous.

masses. 1000 g of carbonisation mass ready for use are obtained.

Example 2. In 47.3% of tempered water, with stirring, 7% of the guaranate fuels and lubricants (a derivative of galaxyanonone) are gradually filled up. Stir until a homogeneous mass is obtained and leave until complete swelling (10-12 h). After that, while stirring, 20% ammonium chloride dissolved in 20% water, 1.7% neonol AF9-12, 4% decanol are poured in alternately and all is stirred until a homogeneous mass is formed.

Example 3. In 40% of untreated water with agitation, 8% of ionohum (a derivative of galactamanon) is sprinkled. Mix until homogeneous and leave until complete swelling (10-12 h). Then with stirring, 25% aluminum chloride dissolved in 200 g (20%) of water, 2% neonol AF9 / 12, 5% decanol and all mix until smooth.
