FORMULA FOR DYEING OF AROMATIC HETEROCYCLIC FIBER MATERIAL Russian patent published in 2009 - IPC D06P1/44 D06P3/04 

FIELD: textile, paper.

SUBSTANCE: invention relates to the textile industry and can be implemented at dye-finishing factories. A formula is suggested to be used for dyeing aromatic heterocyclic fiber material and containing, wt %: 5-20 pigment selected fron the group including TiO₂, 2[Na₂O·Al₂O₃·3SiO₂]·Na₂S₄, CoO·7.9Al₂O₃·0.5ZnO·0.13P₂O₅, CdS·(0.5-0.6)CdSe, CdS·(0.2-0.3)ZnS, 25-30 binding material which is a product of copolycondensation in equal portions of acrylonitrile, butyl acrylate and methacrylic acid, water and the rest.

EFFECT: aromatic heterocyclic fiber material which is more resistant to thermal oxidation and breaking load and at the same time increased fire-resistance as well as uniform and high colours of a wide colour range owing to using evironmentally friendly compounds suitable for using at textile finishing factories.
