COMPOSITION TO DYE TEXTILE MATERIALS FROM POLYESTER FIBRES Russian patent published in 2011 - IPC D06P3/54 D06P1/66 

FIELD: textile, paper.

SUBSTANCE: composition is proposed to dye textile materials of polyester fibres, including 0.5-1.0 g/l of a dispersed dye, 1.0-5.0 g/l of an intensifier - quaternary ammonia salt of the following formula: , where R₁ - CH₃, C₂H₅; R₂ - CH₂C₆H₅, C₁₂H₂₅, C₁₃H₂₇, C₁₄H₂₉, C₁₅H₃₁, C₁₆H₃₃; X- CI, Br , and the balance is water.

EFFECT: improved conditions of labour due to application of low toxic and ecologically safe intensifiers to dye polyester materials with disperse dyes with preservation of intensity and strength of colour and simplified technology of dyeing due to reduction of processing time and exclusion of pH monitoring.
