PROCESS FOR APPLYING ON TEXTILE FIBRES ORGANIC-INORGANIC HYBRIDS WITH NON-IONIC CHROMOGENS IN THE SOL-GEL SYSTEMS

The invention relates to a process for dyeing natural or synthetic fibres. According to the invention, the process consists of the impregnation of the textile fibre in a bath containing 20...60% tetraethyl-orthosilicate , 1...15% sizing agent, 1...30% modifying agent, 0.1...5% non-ionic chromogen, 0.05...0.5% acid catalyst, 10...40% solvent, 0.5...5% cross-linking agent and complexing agent, respectively, 5...20% additional solvent and 10...40% water, followed by drying at a temperature of 20...25°C for 2 hours, heat setting at 100...140°C for 10...60 min and rinsing in running water. Invenţia se referă la un procedeu de vopsire a unor fibre naturale sau sintetice. Procedeul conform invenţiei constă din depunerea pe fibra textilă, prin impregnare, a unei flote care conţine 20...60% tetraetilortosilicat, 1...15% agent de ancorare, 1...30% un agent de modificare, 0,1...5% un cromogen neionic, 0,05...0,5% catalizator acid, 10...40% solvent, 0,5...5% un agent de reticulare, respectiv, de complexare, 5...20% un solvent auxiliar şi 10...40% apă, urmată de uscare la temperatura de 20...25°C, timp de 2 h, termofixarea vopsirii la 100...140°C, timp de 10...60 min, şi clătirea în apă curgătoare.
