WHITENING COMPOSITE AND METHODS FOR ITS USING Russian patent published in 2002 - IPC

FIELD: textile industry. SUBSTANCE: invention relates to whitening composite for textile articles bleaching and inhibition of absorption and adsorption of pollutions or dyes on absorbing or adsorbing substrate. Invention describes whitening composite comprising effective amount of the oxidizing agent source and activating agent of bleach that presents tetraamido-ligand of the formula (I) resistant to oxidation where X and Z mean hydrogen atom, electron-donor or electron-acceptor group; R¹ and R¹¹ mean alkyl and cycloalkyl; M means transient metal with oxidation degree I, II, III, IV, V, VI, VII, VIII or it is taken among 3, 4, 5, 6, 7, 8, 9, 10 or 11-th group of periodic system of elements, system IU PAC; Q means any anti-ion that would be neutralized the compound charge on basis of stoichiometry; L (if it presents) means labile ligand and when it presents in aqueous solution then L means water. Invention describes also method of textile articles whitening and method of inhibition of absorption and adsorption of pollutions or dyes on absorbing or adsorbing substrate. Invention ensures to enhance whitening degree and decrease degree of transfer of pollutions or dye on fabric due to the use of indicated activating agent of bleach. EFFECT: improved method of whitening agent using, enhanced effectiveness of bleach. 15 cl, 3 dwg, 32 ex
