COMPOSITION FOR WASHING CLOTHES CONTAINING DYES Russian patent published in 2016 - IPC C11D3/40 C11D3/37 C11D3/386 C11D3/42 C09B29/08 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions for washing clothes containing thiofenazocarboxylated tone dyes for fabrics and a method of processing textile materials, including such compositions for washing clothes. Described is a method of processing textile material containing polyester and/or nylon, herewith the method includes the steps of: (i) textile material processing with aqueous solution containing auxiliary means for washing clothes and 1 part per billion of up to 500 ppm thiofenazocarboxylated dye; and (ii) washing and drying the textile material, herewith the dye contains a colouring agent, having the structure of Formula I:

,

where R¹ and R² are independently selected from [(CH₂CR′HO)_x(CH₂CR″HO)_yQ], C_1-12 alkyl, C₇-C₂₂ arylalkyl, provided that at least one of R¹ and/or R² represents [(CH₂CR′HO)_x(CH₂CR″HO)_yQ], where R′ is selected from a group consisting of H, C_1-4 alkyl CH₂O(CH₂CH₂O)_zQ; where R″ is selected from a group consisting of H, C_1-4 alkyl, CH₂O(CH₂CH₂O)_zQ; where 1≤x+y≤50; where y≥1; where z = from 0 to 20 and where Q is selected from a group consisting of H and Y, where Y is such as specified below; provided that the colouring agent contains at least one group Q, which is Y; and where Y is an organic radical described in Formula II:

,

where independently for each group Y, M is H or cation, balancing the charge; m is from 0 to 5; n is from 0 to 5; sum of m+n ranges from 1 to 10; each R⁸ is independently selected from a group consisting of H and C₃-C₁₈ alkenyl, and where at least one group R⁸ is not H.

EFFECT: provision of tone dye effect, uniform tone during precipitation onto a number of fabrics.
